Big Bore Installation and First Ride Review - Royal Enfield Classic / Meteor / Hunter 350

- I finally got my Royal Enfield Classic 350 assembled and tested after fitting the 410 cc Big Bore kit. My list of performance modifications now includes: Free Flow Exhaust and Decat, FuelX, DNA stage 2 air filter, Kent performance camshaft and last but not least 410 cylinder Big Bore Kit from Himalayan-tools.com.
Some may say that I should have bought a different bike, maybe just went for the older 500, one of the 650 or a Triumph. However I disagree. One of my main motivations for buying this exact motorcycle was to modify, improve and work on it. In my book the new Classic 350 is probably one of the very best plattforms for doing that.
I must also add that this motorcycle is really capable of handling much more than the 20 hp it comes with. The J-series engine and the new frame is excellent, and much better than that of the older 500 (trust me, I owned one). If RE Could I do believe they would have built it more powerful from start. Maybe as a 500 cc 35 hp single. It is way capable of that!
Seems perfectly logical to me. Agree, or disagree? - feel free to start a discussion in the comments section - Auta a dopravní prostředky
Congrats on the build. I am looking forward for the dynotest results when it is run in.
I really like your mindset. You are riding because you love riding and you are tuning this "slow and cheap" bike not because it is economical to do so or because it is easy. You do it because you are passionate about riding a bike you love.
That is the mindset of a true biker in mine opinion.
Ride safe and love from a swedish veteran rider. 👍
Thanx. Thats really nice words!
I like the idea of this kit but would prefer if it was sold in the UK through Hitchcocks, just for quality assurance and service support.
True. I think they will eventually.
Now that you’ve had a bit of time to ride what, what’s the difference in fuel consumption compared with stock?
@@ironspur2000 sorry. Haven't measured. Will do, and post an update
@@MotoMorten thank you
Your all videos good
@@jagjeetbhinder5024 Thanks 🙏
hell yeah
I’ve done all the mods on my 350 apart from this piston upgrade, we use our bike to ride 2 up and the mods have lifted performance and power 25%, but we only tour 40 - 50mph. It’s great when I’m riding solo - the only trouble with the upright seating position is that above 60mph your torso catches that much wind it’s unpleasant.
I have a 535 Continental GT, and you ride prone cafe racer position, with a small deflection screen over the twin clocks I can sit at 60 - 70mph with no wind. I’m investing in increasing the performance of the cafe racer to 612cc with additional performance upgrades. I think my money’s better invested in that rather than the 350.
Put a oficial windscreen on the 350. It Will transform the bike. No more wind problems untill top speed.
New sub here, awesome videos! Just a request.. could you attach the gear you use to the video description? It's a really cool jacket and helmet you have, I was wondering where to look for it for something similar
@@Grupp87 Thanx a lot. The jacket is Swedish , Halvarssons, and about 25 yrs old 😅I will post a full review with gear later this summer.
I luv royal enfield 😊
Very nice. If you could pop over to England and do mine that would be great. I do offer free tea and coffee.
Thx. I would love to 😊
I would like to know how it runs with the stock front sprocket and a HNTR 350 throttle body. (without speed limiter) Is that someting to consider? Cheers
Yes. But Id rather go for a carburetor. Maybe next year
I remember seeing someone follow a certain sequence to allow the ecu to relearn the the new fuelling. Might be beneficial to check 👍
Thx. Will look it up!
Do you have a link ?
Great endeavor!
Could You please share the video where You installed the rpm/tachometer?
Thx. Sorry. I did not make a video on that
Stewart Fillingham has a vid of installing one. It's the Daytona Velona from Hitchcock's.
Hi, thanks for the video! What are you modifications? Does the motor missfire a lot? And what is your break in plan for the new cylinder? Thanks a lot in advance 😊
@@jakubs318 hello. I have made a lot of mods. Please see my other videos for details. The engine runs fine. Some misfiring when its cold, othervise not. Running a bit carefully for the first 2000 - 3000 kms.
You try 16t/38t of interceptor650 feeling good. Gear 3 120KM/H.
Cost wise, considering that any upgrade would be done by a local bike shop, which is the most effective to get some more torque for a Meteor used on hilly roads with 2 people? This big bore reminds me of my old Vespa PX which was 125cc a long time ago, but now runs like or more than a 200cc
@@andreaceria8481 for more torque it is the big bore that counts. Camshaft is a much easier (and cheaper) job, but primarily adds to mid and top end power
Hei,
Bestilte det samme settet, så at de hadde 500 kit også men det krever mer styr og montere også var det mer usikkert med mapping osv. 410 kittet var mer «bolton» følte det var tryggere. 👍
Akkurat det samme jeg tenkte. Ser at folk sliter med at kompresjonen blir for høy også. Tenker det er økt risiko.
kanskje mer sannsynlig å riste kraftig til jeg kan tenke meg
What’s the compression ratio of the 410cc setup? I think stock is only 8.5:1
I'd be interested to know what the (comfortable) cruising/top speed is now.
In my opinion this is mainly affected by the larger cog. Thus 7% higher than before. The big bore makes it easier to sustain a higher speed even in ahead wind and or going uphill, and of course make the bike pull harder when accelerating (ie out of corners). Short answer, I would say 80 to 100 is ok
Morten, any updates on the kit? Mine is currently being shipped from India and I’m going to do the installation myself like you did. Together with the Kent camshaft and catalytic converter delete I hope it wil make a significant difference.
@@RB87NL yes. It works great, just haven't gotten around to doing a more in depth review
@@MotoMorten Thanks! Really looking forward to the arrival of the package. Did you re-use the original camshaft retainer bolts? The manual specifically states to change them. I have re-used them when installing the Kent camshaft but I am hesitant to re-use them again.
@@RB87NL yes I did
I think your logic is sound, but not so, if you have to pay someone else to do the work for you, ive added K&N air filters and air intake external sensors to my 1200 Speedmaster and 500 Classic (fitting a vibration reduction plate to my Classic today) and both serve me well, i would like to know how much your upgrades have made to your bike?.
They made a lot. And, yes, doing it myself is maybe the main part. Learning and understanding the machine.
I think RE gave the new 350 a counter-balancing shaft. If they made it a bigger bore they would have needed a bigger balancer to get it as smooth as it is. They could have made it a 500 but the balancer made them go with 350cc. I suspect the 410 kit vibes a bit more than the 350 but who cares? You should try my XL1200..
I think the only answer is emissions. As for the 410 kit I do not notice more vibrations. Guess the piston is not much heavier. Also as you say, vibrations are sharm.
That big bore kit is amazing did you notice a change in top speed ?
I dont go that fast. Excluding the speed limiter I believe it would increase from 130 to 145 or something around there.
Tis FAB🎉🎉🎉❤
Thx
I've got a hunter throttle body coming. Apparently, this gets rid of the rev limiter.
It does. (187) but the only road you get it up over 80, be a main dual carriageway or motorway. Then you run the risk of done for speeding 😂.
Bumble got the dna filter and plate, red rooster exhaust and de cat pipe, fuel X lite, Kent cam, and unrestricted throttle body from a Hunter😊
Sat the bike for a good half hour, to re set the ecu.
Great video, but, think I done enough mods lol.
Look forward to the dyne runs, should be big improvement. Great work though 😊
@weemark67 mark is there a specific fuel x lite when you swap the throttle body or just put the meteor one on?
@@scottishian150 just the normal one. I didn’t bother with the one that’s got the different maps etc. Bike does feel cooler when running.its fitted under passenger seat pad.
The rev limiter you want to keep, but the speed limiter yes. I however barely ride that fast. Even with all my mods I find this bike to be best at 60-100 kmh
@@scottishian150 just the normal one….can be bought from Tec bike parts or Hitchcocks.
I went for the Lite due to it, being basically auto. The pro version has, I think 10 maps. You be fanny’in about try the settings,which be a pain in arse. Probably end up on the one, the lite is set at…..lol.
hopefully someday we get to see the carburetor conversion :)))
The music spoils it for me- I wanted to hear the bike.
Sorry. In the full review and dyno I will use a proper mic for the engine sound
@@MotoMorten thank you
so where can we order one of this Big bore kits?
@@davidn1562 www.himalayan-tools.com
How is it going im in the uk and thinking of getting the 410 big bore.... Do you still recommend it 👍
@@DR-lg6xr Sure! Works great 👍
@@MotoMorten thank you.... I think i will purchase for my hunter 👍
Looking forward to your next video on it
hey mate, does that tool roll rub off the paint on those forks?
Would, but I put some protective film between 👍
@@MotoMorten can you suggest or show what film you used? Id love to put my tool roll in the same spot
No link on where it was purchased?
Sorry. www.himalayan-tools.com
Nice job, looking forward to seeing the dyno results! Just wondering if you still hit the ~75mph/120kmh speed limiter that's on these J series bikes?
I imagine that he does, as the limiter is governed by the ABS sensors I believe.
@@BulletBeena would removing every other spoke on the abs disc fool the sensor ?
@@PaulBrooke-qo3hn Interesting idea. I have no clue. The extent of my mechanical knowledge runs to making sure I put petrol and not diesel in it 🤣
Maybe cover some gaps with tape
Thx. Yes I do!
What Company manufactures these big bore kits.?
Dont know. Sold at www.himalayan-tools.com
Thank you! Looking forward to your videos describing this mods performance!
This is a great video - what do you reckon - which installation would give you better performance: camshaft or the bigger bore kit? Thank you!
Thanx. The big bore kit does more to the low end torque and also top end power, while the camshaft only gives a bit more on top. So I would say big bore. However it is also by far a bigger job.
@@MotoMorten No doubt :) Did you have any troubles putting back the time chain and adjusting this? Did you follow any video or manual?
@@arekwi6682 I followed a video. Lost the cam timing tool and adjusted by eye measure. Works great 🙂
What's that small meter for?
Tachometer / RPM
What about Next Video? waiting 😢
@@rishiray26 Thx. Will do a proper review on the big bore kit later this summer.
Where is the Video?🥺@@MotoMorten
@@rishiray26 sorry haven't had any time to film 🙈
Research counter steering br
Buy yourself the 500 classic and save the hassle😂
The thought had crossed my mind!
Nope. The 350 is a much better bike, the j series frame and engine is a much better plattform to work on and get great results. Trust me I have owned a 500. Also I am modding because that is the goal by it self. I want to do it, and live doing it.
Find one
I'd rather keep my testicles from jingling numb all day 350 has a splendid Balance shaft
Tickert ganz schön heftig. Ventilspiel viel zu groß?
Ohne das gemisch abzustimmen (Einspritzung!) wird das gar nix bringen. Und wenn es von 21 auf 24 ps steigt ist das immer noch nichts.
Ich würde das nicht machen und mich an dem motor wie er ab werk ist erfreuen🫠👍🏻
it's wonderful to modify your ride but taking a 315 train to ring more power out of it is a lost battle before you even start you just threw good money after bad to get marginal improvement in performance that really isn't going to equate to a long-term improvement in your riding experience on the 350. If you're going to ride at 350 you had to change the perspective in your mind not the horsepower that the bike puts out it's a different philosophy and unless you can tune into that you're never gonna make it satisfying.
I think you miss the point in his doing this.He does it because he likes the Classic 350 and he likes to tinker with it making it his own.I commend him for his attitude.He takes a very modestly powered bike and makes it more suitable for his pleasure.I have a 350 HNTR i'll be putting this big bore kit i it and messing around with it.I could easily choose to ride one of my big bikes nut I choose the HNTR and the others sit idle.It's a Royal Enfield thing that a lot don't understand.I rate my Classic 350 and HUNTR 350 more fun than the bigger bikes.
The 650 RE is great after you fix the problems.
Like the terrible forks.
And the not great shocks.
The heavy and bulky exhaust. 😂
@@AlanRosborough exactly!
You are probably right, but also wrong. As alan has posted I do this because I love to do it (by it self) and also I want to get the most out of this lovely little machine
That bike is built like a tank it will easily handle the overbore
Loose the annoying music please
