Great bike. As a 73 it must be one of the last.

Good work. Pretty bike!

Great Video! I have dreams of you someday fixing my dad's Triumph.... keep up the good work! you and your wife are the coolest!!

What a beautiful Bike. Great job!

Great job Randy! Question about letting carbs run dry, is there a long term effect caused by not letting them run dry?

I used to own an RM250C2, same year model. Fast motorcycle for it's day. That is a great finish on the restored engine by the way !!

Hi Randy, Fore how long time do you soak the clutch plates?and what kind of oil,and how long will this last, br jan

i happen to be in bombay and was in kathmandu in 2013 , i was 23 and i saw a honda 50ss moped out side a bread shop , your bike reminded me of that , very nice bike

Im no hater. Its dope. #Zilla

I had one of these was a great bike

Randy your bike is not a 73 or 74 checked the first three numbers on the side case I believe it will be 166 that is a 1976 Bultaco did not shift on the left side till 75 but it looks like a very nice bike just like that 72 you had a while back

Utterly brilliant video. So much useful information, clearly explained. One of the best I've seen

How can you identify the different types of carburetors prior to disassembly? Thanks, Dave

The makuni carb has a fuel inlet , is the button and other small inlets for? Are they all only vents? Also does it run on oil mixed fuel?

i have a 97 kawasaki ke100 cant get the bike to idol

Great instructional video. Thanks for posting this. I restored a Yamaha Phazer II snowmobile recently with twin Mikuni carbs that have the cable type plunger/spring system that you showed. I have been starting without the plungers and cable installed and it starts great. Yesterday it got down to 15 degrees and wouldn't start right up first pull like it had been. My question is, will it make the sled run poorly without the plungers installed? Based on your video it sound like without them installed I am essentially keeping the sled "choked" or enriched at all times? Problem is that it came without one of the plungers or springs. Thank you

Very helpful and useful video thank you so much

Hi Randy, i installed a mikuni 28mm type 360 on my jawa 350 twin. The choke- which has 3 positions?- does not work.. so have to start the bike without- ver hard.. then if it runs and i press the choke, the engine will die within seconds. This carb does not have a separate choke jet?This cannot be normal.. any tips?

pls help..my carb start 1 kick..but i go to on road my motor shaking canot go fast full throttle like no fuel.whats the problem?

Thanks so much Randy on the great explanation.

Beautiful!

lots more crome on u.s. bikes to uk bikes

Thanks Randy, great video!

Good instructions !

Jolly good show! May I ask, how many labor hours went into this resto?

Hi I hear it has higher RPM at idle when You pulled up after riding it is that normal for this bike? I have exactly same bike and my RPM's go hey wire too I think I have vacuum leak in one of the boots

That kicked over easy, you can stand on my kick start , if my bikes not at TDC you will get a kick back too.

...yet another work of art from you Randy and another great video to watch - very enjoyable - thanks...what a magnificent bike the 'Interceptor' was...(is)...beautiful..

Beautiful bike, lots of stuff on it says later Mk1-A. Rear mudguard, lack of tool box, seat. Must have changed out for Mk1-A for convenience?

awesome restoration Randy! that bike looks phenomenal!

Man, that thing sounds fantastic! I was a big time biker back in the 80's when I was young, and I remember how badly I wanted one of these but couldn't afford it. Watching this video gave me wood!!

Why was it idling so high?

Good vid., thanks.

Great job. Well done bringing it back to life, better than new, it seems.

Thanks for this vid. This really explains WHY the choke cable is missing on my Amal 930. There is a choke plug replacing it. The bike is a '57 Triumph Frame with a 62 TR6 motor with a 70 AMAL 930. Chopped and Bobbed. Bitch for me to start cold. But this explains lot.

So if im not getting any ohms from the rotor rings or the white and black wires it is safe to assume it is bad?

Thank you for the insight..

have u rebuilt / restored / repaired ab Enfield 200 (mini bullet)

Try not to laugh but I have just been trying to get a BSA B31 to run properly with no success it turns out I have had the choke open all along a thousand blessings to you for the video

Thanks for explaining the Mikuni carb 'Choke'. That thing had me so confused before I watched your vid.

Spot on Andy really nice bike want one

Is there work in this profession abroad or to change my folks this work and good Mahwalaml abroad because I love to work abroad this profession is mechanical Thank you

Very nice video,great detail! Im rebuilding a rusted 72 BSA Thunderbolt right now, it won't be as period correct as the one in your video, but it should be a good starter british bike all the same.

I wanted to figure out how to clean my carburetor. It has been parked for about 4 months while away and when started, it started stuttering. I figure I should clean it, get fresh gas and I should be good.

Maybe the cylinder wasn't bored the last time it was apart. Just honed. You'd expect to see more wear lower in the cylinder as the piston speed is higher there. But, I expect you know that anyway !

tyvm sir, i got my problem solved

On my 85 Honda Rebel... it use to be you choked a cold engine to start it, tweak the choke, and once warmed up you could turn the choke fully off. I assume that is normal and makes total sense to me. Now however, I have to choke a cold engine as before, and tweak it... but the engine seems to run best once its warm with still a bit of choke on. If I turn the choke fully off, the engine will stall out with no throttle like at a stop. I've adjusted the idle screw so it wont do that , but the engine still has a sweet spot it likes to purr and run at when warm and under power with the choke a little on. I don't know if the Rebel has a real choke, or enrichment circuit, or both. It seems to be able to do a fast idle with choke as you described during start. What should I adjust? I'm trying to think maybe I made some changes inside the air box a good while back with a new filter, with maybe a filter that lets air in easier... and maybe that's why it prefers a slightly richer mix. Someone also took a broomstick and punched out the exhaust pipe internals before I bought the bike which might also be letting the air flow out more freely and make it run leaner than factory. I'm going to check the air box tomorrow and see what I did... and if a thicker filter fixes the problem.

excellent video thank you, this has really helped with my restoration project
