Loud pipes do save lives, cause when your neighbour breaks your legs,it stops you riding.
🤣
Carbs designed to run with an intake plenum, and fuelling problems running them on pod filters. A tale as old as time.
100%.
Neighbours - "right, that's it.
I’ve had some loud bikes… and I’d be complaining.😀
I'd be complaining then looking around the bike asking if it's for sale
I think you nailed the description " it's the raw essence of a motorcycle" that's a great description. Ive never ridden a hard tail but i do appreciate the engineering and skills that go into building custom bikes. Its raw and barking mad and we need that every now and then👍
that carb holding jig is the bollox
Yes, i was thinking the same thing!
me also. reminds me of the big engine trolleys that can mount and flip engines... but tiny.
I came here to see if anyone had asked for a brand/model number or link because I can't find anything similar in a brief search. Might have to make one.
It's even got a little dial thingy mabob that tells you how many degrees you are turning it around. Which will be very useful for something I'm sure.
@@WhitneyStephenGater MeToo. Please let me know if you figured it out. Thanks!
I have absolutely no idea what you’re talking about most of the time but it’s bloody fascinating when I do!
If them carbs came form a older GSXR that was used for drag racing on methanol and alot still are that would explain your odd shape needles as they flow massive amounts of fuel at wide open. Im saying this as Iv had people turn up with old racing parts thinking it just bolts on and work and have seen a few ex drag racing carbs in the past with wild jetting for methanol and the like.
You might be right about that. Pure ethanol requires 45-ish % more fuel with the same airmass. I experimented with e85 in a turbo car. Runs great if you get it right.
So that would explain those huge holes in the emulsion tubes.
I used to ride a Kawa Zephyr 1100 and i tuned it up a bit. K&N in the airbox and the airbox opened up on the underside. Dyno jet stage1 kit with 98 mainjets. Factory was 95 mainjets. I messed around with needle heights as well.
On the dyno it made 98 wheel HP. Stock was 95 crank HP.
It ran like a peach, pulled really clean from low in the rev range. I once managed 19km/L just gently cruising. Not bad IMO.
This bike with the Bandit engine could do the exact same thing.
They are VERY strong HARD pulling engines provided it is tuned correctly and synchroniced correctly.
I had a couple of 1200 Bandits, the first one I dynotuned, more than enough grunt, especially for Euro touring. A mate put a turbo and open pipe on his, it would wheelie at 100mph and then spin the rear tyre if he opened the throttle. Absolute death trap anywhere except Santa Pod.
Excellent 👍
I’ve got an early 600 Bandit, I fitted a GSX 750 cylinder and pistons (machined the tops of pistons to reduce compression as I refitted the 600 head) rejected carbs with a Dynajet kit, K&N air filter in air box, 750 exhaust. Makes a fair bit more power and torque which made clutch slip, so I added washers to preload clutch springs which cured the clutch slip
The clutch slippage is the only safety feature on the bike :DDD
Well done mate. Honestly it seems like it would have been just better to keep the 1200 bandit stock and ride it like it was meant to be ridden.
Suzuki engineers would commit sepuku if they saw this abomination on 2 wheels.
Wow! I was not only impressed with your rejuvenation of the carbs but your test rides along the narrow lane was well scary. An awesome video 👏👍👌
I just discovered your channel, absolutely loving it, I can't wait for the next fuel injection episode on the v4
Yep, this brings back memories of my bandit. I had the lean issue on mine but whoever worked on it before me messed around a bit too and drilled the jets also. I changed the complete diaphragms and went up to bigger mains and pilots and runs like a dream now. From what I've heard these bikes are best left stock unless you know how to properly tune the carbs or are willing to pay someone that does!!! Thanks for another great video
Love it when Jim gives it the rice and we see the beans!
the bin lorry is new, it has a personalised number plate E15 GWM. stands for Grundon Waste Management
I was gonna comment this. It’s a 1987 cherished plate
Superb channel. Love your honest presentation style. I appreciate the massive time consumption in filming and editing…..thank you.
You are the BOY Jim . FANTASTIC again. Thanks to you, I fixed my ZXR 636 which had a blocked pilot jet. Look forward to your next one. Trying to sell lit by the way. 👍👍👍
Nice exhaust manifold at leat a good attempt at equal lenght pipes
I must be getting old but so does that exhaust..and quick
Yeah love watching you working on carbs, I had a CB450 K5 with carb probs mainly on one, never got to sort it after what seemed too many attempts before trading it.
Good video especially the discussion on emulation tubes and needles. Like your carb jig! Thanks for the Fowlers link, I’ll check em out!
What I love about hardtails is that you know exactly what that rear wheel is doing!
Yes it's busy trying to smash your spine😂😂😂😂😂😂
And your back tells you to book an early apointment at the chiropractors.
I've only discovered this channel in the last week or so, and I've been binging on the vids. Loving it to be honest, waffles and all! And I'm a MK1 1200 bandit owner and DIY mechanic. This is RIGHT up my street.. 😂. I've got one really annoying question about the cold start on my bike. Considering accessing the hive mind on Discord...
My dad raced a 1939 Tiger 100 with a rigid rear end back in the early 70's. He had Ohlins inner tubes fitted.
What… in his spine? 😂
WTF ??
Great stuff....Thanks for passing the knowledge.
That carb strangeness was definitely strange, you need to know your shit to suss that out. The bike Looks and sounds great but I also like my kidneys the way they are🤣
great job again lad keep it going sounds sweet enuff
On my 6 bandit it was the tps that was wrongly set ,took two years to figger it out ,runs brill, now lovely bike.
We need more of this educating about motors.Enjoyed it.
I think the slipping was your urine on the rear wheel lol
Always enjoy your videos 👍🏻👍🏻
Hardtails, great fun on the bends 😁😊
I really like your protective riding outfit....smart! As for your scarey narrow roads I could never confidently ride there
You have me cracking up in the first 3 minutes. 😂
Hello Superbike Surgeon, your videos are fantastic. Information is clear with great comedy. I have to ask where did you get your carburetor set up sir? It looks like something that you made yourself to mount your carbs on, but I have to ask in case there is a place that sells them. Thank you sir and keep up the great videos 👍
Just found this channel. Sign me up, someone seems to know their stuff. 👍🏼🏍️
I'm enjoying your videos, I've only just discovered your channel! I own a '96 1200 Bandit with an after market manifold (no flame trap) and disgustingly loud pipe. A friend of mine bought it new and I had it off of him two years later and got to work tuning it. K&N's and a Dynojet kit didn't make for a happy combo really (even after lots of time on a friend's dyno) so, I ended up re-fitting the airbox with a one piece K&N and tuning the inlet of the air box with various bellmouths until it ran right. The standard clutch soon shit itself and died and a Barnet clutch now has to cope with it all ( into the second set of plates now). It's a great machine and I'll never be able to part with it. Thanks for the entertaining vids!
You know your stuff
Respect
Now go for a lay down and thank god your alive
I fitted a dynojet kit to a gsxr750wn which came with emulsion tubes back in the 90's.
Also noticed the over-reving on acceleration. I had a similar problem on a Ducari ST3 a while back. It was so bad it warped the clutch basket! After a lot of fiddling around, turned out the previous owner had changed the levers and the barrel in the clutch lever which has a small pin which pushes the master cylinder piston was mis-adjusted resulting in the clutch never fully engaging.
Thoroughly enjoyed your video. It was great commentary 😂 did you sort the clutch out and see what the power was like ?
I want, need, one of these carb rack holders. What a device!
‘I’m not gonna go far, it’s terrifying’ 😂
What a true craftsman you are!!
Is a hardtail, bad for the spine after a while Jim😅, great video, really enjoy them and also gets baffling 😅, but very interesting
Great vid - nice carb geekery. Front brake pipe looks like it’s pulling when young open the throttle- could be the camera angle.
Geez... That noise hurt even through the limitations of audio processing.
PSMPLOL. Good effort. Seems like a nice scoot to me LOL!!!
Fowlers are awesome. Even if a part isn't in stock they will get it for you normally within a week. Fantastic service.
I worked there for 13 years and you would not believe the story's I could tell......not just the customers either !
They look like Skoal Bandit needles so they maybe Skoal Bandit carbs?
It may also explain why I was forever replacing broken needles. All that flapping about in the jet makes perfect sense to me now.
VM 33 smoothbores took me two months to sort,running open trumpets on my hot GS 1000
Brilliant video Jim.....
I had a cb750 like this is was a nightmare i told guy buy new carbs or sell it. He sold it. I also thought my clutch was slipping on my Z750, my rear tire was spinning......
Thank you, CZcams algorithm - instant fan
Hi Jim, Once you get off that bike you will be walking like a piece of 6x2. Great work with sorting the problem out as always your expertise shines through. Just one question, admittedly nothing to do with the bike. What make is your camera you use for all the footage? Keep the videos coming there are great. 👍👍
Innovate wideband isn’t really a “gas analyser” and placing it in the exhaust outlet at idle isn’t usually enough to get an accurate reading but certainly better than nothing.
I had use of a kane ega5 gas analyser to troubleshoot a misbehaving delorean - very expensive piece of kit, but it works at idle speeds because it has a vacuum pump sucking gas into it (essentially MOT standard equipment) had provides hc, o2, co and afr/lamda
Cool work mate
Reminds me of my old hardtail Honda 750E. I had the Motor built to 836cc. It was good for a 140mph.
18 years I rode that thing.. It's sat so low, no kickstand required.
Miss it...Age.67🇺🇸Veteran
Old saying over here... Chrome don't get you Home.
I would say the idea of the custom needle & jets, although badly worn, was to deliver a rapid feed of fuel to work in harmony with the short headers especially around midrange as theirs little to no back pressure 😀 😮
The bracket holding the carbs has a degree wheel. Can this be used the replicate the angle of the carbs when fitted to the engine\bike when setting float heights?
The clutch slip... I boosted the power on my 2000 r1 and started getting clutch slip in high revs. turns out lots of bikes clutches don't like fully synthetic oil. after a recommendation from a local old bike mechanic I switched to semi- synthetic and rides like a dream with no slip
I run fully synth (motul) in my 2001 R1, zero issues, bought it brand new in 01, and it had fully synth in from the factory and ive always used it. Having said that, Yamaha clutches of the 80 & 90s are a notorious weak link in their otherwise great engines.
My tinnitus went into overdrive and back went into spasm 😮 Looks like someone didn't understand carbs and did a right old bodge. Bandit 1200 was always the same size, the earliest ones had 1156cc on the barrels, all the engines are 1156.79 cc. Love your videos Jim 👍🏻🍻
OR they tuned it for e85 or pure ethanol. ( needs about 45% more ethanol for the same airmass.)
Once this new owner started to run the bike on gasoline using the ethanol tune it obviously began to run run PIG rich.
Got to love the old oil cooled engine, Suzuki dropped it so many models, From the early GSX-Rs to the GSX 1400, I have the 1156cc engine in my GS1200SS and the 1052cc one in my 86 GSX-R1100.
It sounds like all of the drivable vehicles in the Half Life 2 series all at the same time.
My TV fell off the the stand....lol
That noise..
I thought you were going to say because this bike doesn't have any rear suspension 😁
I always thought the binnedit was a bored but de-tuned gixxer engine. There used to be a chap that regularly turned up at the red lion Avebury meet on a gsxr streetfighter that sounded like that…..wonder why it’s no more?????
Lol great review… Love that bike🤪
my OCD in me is saying i need to get out to yours and sweep all the shitty gravel and muck off the road to your place lol
🤣
An entertaining video, good work
Great work
Now that is an interesting machine. I like it.
1:51 😂 Ha! Caught ya!
8:15 I went to the website on the side of that carburetor service tool(??) and cannot find it! I need one in my life. Is there a part number on there, or what is it labeled as? Great video as always.
Where's the little carb rack holder thing from fella? Cool bit of kit that
I have been wondering this too. Why does it have angles on the side?
@@paullyons4624 I suspect it's either made from a few other parts or the dial indicator is for setting float bowl hight?
We might find out if he sees this lol
Jim Likes ProBike so maybe an older version of this...probike.co.uk/diagnostics/carburettor-stand/
@@paullyons4624 also we share the same last name, brother 🤣
WHY???? My back aches just looking at the rear end.
Back ache isn't cool. Grit you teeth and go!
Yeah makes NO sense… and only [remotely?] doable if the seat is heavily “sprung” [which is the normal way?]
@@Studio51media Nonsense. People have been riding hardtails for years, you just need to man up.
Its a chopper.
Around 86, a friend asked me to ride his bike up to him when he moved to the far north of New Zealand, 380km on NZ roads (they were far from smooth back then, and about 100km was not even sealed🤣) On a rigid tailed monstrosity made out of a 71 500cc Triumph Daytona. The breakdowns, and there were many, were a godsend, it meant my arse and back got a short reprieve from the torture of riding it.🤣🤣
The exhaust noise is personal preference....If you want quieter have the pipes end behind you instead of in front, if it's still too loud install mufflers.
Super random, but you were right, the bin lorry was brand new, the number plate was a personalised one, notice how it only has 6 digits👍
When looks take precedence over function; curl up a hot exhaust in the path of the cooling air to the engine.
My wife had a bobber with an early 80's Yamaha inline 4. I couldn't ride because the inside of my knees were right against the corner of the head.
The teas a good idea thanks .
It’s a Suzuki Bobber. In the Classic looks department it’s spot on except for the “artistic” take on the header. Shouldn’t be to difficult to sort out the fueling.
I know several people with serious back problems because of riding hard tails. Some are in wheel chairs today.
i was watching an old guy riding a chop at the tt this he had a suicide shift with the clutch on the gear handle
It is possible to get it jetted right but you need a LOT of experience and practice on CV carbs with K&N filters and new 'custom' emulsion tubes. (I haven't made emulsion tubes in years, eyesight ain't what it was)
The only person who could do it 'easily' was Leon Moss (LEDAR RACE DEVELOPMENTS) but he died in a hang-glider accident many years ago (he did the carbs for Honda UK in the 80's when they used the DOHC CB750 bored to 998cc, better motor than the longer stroke CB900F)
I haven't found the Dynojet kits particularly great but they can be made to work if you have the full kit with new needles.
1200 Bandit with earlier SACS GSX-750 intake cam plus any decent pipe will give reliable 141bhp at the wheel in a street bike, although I haven't done one for probably 25 years.
I guess that's what's called a visceral experience
Get a ride to Scottsdale Az you can stay in my condo and rebuild the carbs on my GFS 1200s it's a nice 46 Celsius right now 115 Fahrenheit. Lol.
That maze of pipes right in front of the engine keeps the bike and your legs very cool around tiwn😂😂😂😂😂😂😂
I did this very job on a GSXR 1100 streetfighter i built about 30 years ago
Great diagnostic skills jim,no compression test ???? Lol.
Great work, I've got a 1200 bandit mk2, and it's running a black widow full exhaust with stubby end can. The carbs have been rebuilt as standard, but it blows a lot of soot out the exhaust, do you think it would benefit from a dynojet kit? Thanks, liked and subbed 😊
I love the pipe! It might be dogpoo but I love it! Remember the South Park Harley Fags episode? I bet the guy who came up with that exhaust watched it and thought "I can do better!". But it looks so cool.
I won´t laugh at Your expressions after all the beans are present, now. I once had a bike in wich the swing bearing was rusted shut.
No movement at all, it became a hardtail and I hated it so much. The back was jumpy like hell, a little pebble in a curve on my lane made the rear wheel skip and slip. It was bad. So: I´ll never ride a hardtail but they look so cool, too.
Keep the sticky side down and the shiney side up, You´ll be allright. G`Day, Sir!
Congratulations on getting to 30K subscribers and well beyond in a week.👍
Why would someone put spikes on a bike?
That bin lorry looked to have one of those plates to show its an EV 😂😂 no wonder it's fooked.
EV, eventually void.
I got a carb rebuild kit for my early GSX-R1100 from a place in Japan that had emulsion tubes with it, when i got them it was clear they were Mikuni knock offs, the threads weren't Mikuni pitch and couldn't even screw the jets in, used a few o-rings and gaskets, the rest went in the bin.😏
Chineesium parts
@@NormanGnome11 Yep, made out of pure chineseium😆
Wicked bike 👍
I wanna try it!
Read the unedited 'second' post before this one. I didn't watch video when I made comment.
That taper on needle will only be rich when slides are fully lifted.
Mains are too small, unless those 'pods' are very restrictive, which, looking at plugs seems to be case..
I ran 117 mains in a slightly modified 600 Katana with K&N filters, pulled way better than any 600 tourer should right from idle (had way too much experience with SACS motors, was at Suzuki dealers when they were launched, TWS, Bridgend)
Did you pull fuel screws and check for damage? I always found either o-rings missing or they had been screwed in too tight with either broken off tips or enlarged hole. Things are a LOT easier nowadays with all the 'stuff' available
I had to send someone to Fowlers with parts to match up because Honda screwed up on the RFVC head part numbers, the rocker arms are 'diagonally' the same and not intake exhaust like normal SOHC motors.
The 'squared off' numbers/letters meand they are precision machined to closer tolerance than 'ordinary' Mikuni emulsion tube/jets, etc.
I always check the emulsion tube cross drillings, almost all aftermarket and many new have 0.60mm hole when standard size (back in the day) was 0.8mm
(I trained as precision machinist in mid 70's built some 'interesting' bikes over the years)
Oh, how the hell are people getting away with exhaust systems like that?
When I was doing MOT's it would never fly
BTW, I had the very first official mobile repair service in Britain in the 80's (plenty of people did mobile servicing but no one had officially done it).
I think the tax man really hated me. 😇
No front guard, be fun when it rains!
I recall reading an early review of the 1200 Bandits, that described it as a 'stupid bike'. Not, the writer explained, because there was anything wrong with it, but because the power & torque in the basic naked bike made you want to do _stupid things._
In my experience, when a Bandit's running lean it makes more power than it ever did...
...for about 5 minutes.
Then it'll start transferring piston metal to the exhaust valve before it burns up.
It had all the signs of rich running.
102.5 and the needle on a standard should be on the bottom slot dynojet jets there own sizes , mikuni 107.5 be place to start.
