This video series has helped me a lot with my build thanks for putting it up. I've tried running a 42 mm aftermarket carburetor to my 300cc and it didn't have the best of effects on the performance I know that's quite oversized for the engine is anyone here running a larger carb successfully?
The issue is that I am 60 this year and although I thought I would never say this, I am happy it reaches 70 mph it could do more however I did all this to make it sound and feel like an old British thumper and it does. So I won’t put it on a Dino I am happy with how it feels. Many thanks for your interest.
Hello Mr Mark, again I want to say thank you for this education video. I tried to install a big bore cylinder myself but unfortunately I had to abort the mission, and when I put the old cylinder back and everything else together the bike won't start. The electric part is ok and it made some noise but the engine just won't crank up. I think the timing chain is not properly timed/ tensioned. Any suggestion? I have a Suzuki Marauder 125 year 2010. Any comment will be appreciated, thanks and Happy New Year.
hi Mark...what you can sei about the new balance of ensemble of all the parts...new the new piston is little more heavy than original and the segments to...???
Great job .. downloaded and watched on a long flight .. made the hours wiz past! I have a TU250x (1997 (still going well!) .. same engine by the looks of it, so really interesting to see the motor build, just in case I ever need to do it! - thanks for sharing .. I’ll watch the test ride next! Cheers from Australia!
Well l enjoyed that, learned a few things,l,ve a Suzuki gn 125,"Don't temp me"😂 Good to see a good program of work on TH-cam.Hope there's more to come.
hi please do you know how i can set up the clutch command because he is accroching too late i want it more short . the cable is at the maximum . maybe i can set up the command on the box?
You have to lose the cable, not tighten it. It must have a half of inch of free play, at the end of the handle leverage. Also, the best way is to put into first gear, engine off and push it with your feet, you can understand clearly how and where it grabs..
The best way is to go on e bay and see if their is a kit, they tend to come from China and work well. Secondly go on TH-cam and see if anyone has done this before. Good luck.
Hello good mark I've an 150cc HI-REV motorcycle I'd like to convert into a 300cc how do I go abt that build, an how do I choose the right big bore kit for it I'm from jamaica
Hello Mark, enjoyed the videos with the conversion. Is there another test on a dyno in the offing? to see how much horsepower you have found? Greetings Timo Hagedoorn Holland
Do you know the part number for the spark plug I have a suzuki extreme baja 300 that I bought with a bad head I replaced the head but the plug the old head had was not the correct one for it
Полезный апгрейд, но хотелось бы это видеть в одном видео, а не в пяти. Очень много приходилось перематывать. Но за работу 👍 Себе тоже хочу, но путем установки гильзы от гольф 3 и с головой на 2 клапана, а не 4.

Wow 70 mph. That is good to hear. Getting close to 60 too. But 70 is a good cruizing speed for trip to Sweden from Holland. Thanks.👍
Glad you found this useful, I kept with the standard carb and a slightly filed out main jet, it has worked fine. Good luck with finding a solution.
Holy shit this is gold. I got myself a GN250 and these videos is alot of help.

Well done, Mark. I really enjoyed watching you do this step by step. I even had tea breaks as well while watching.
🙂👍

How we men suffer, she is now hinting about getting a motorhome, that blows any future build for the moment.

Just watched all 5 parts on the fitting of the big bore kit, enjoyed very much keep them coming Mark.
The big boar kit and altered rear socket make it a very relaxing bike to cruise on.
Well l enjoyed that, learned a few things,l,ve a Suzuki gn 125,"Don't temp me"😂 Good to see a good program of work on TH-cam.Hope there's more to come.
Thanks for your kind comments
Good job Mark! thank you for sharing the video, looking forward to seeing the update.
Wow, looked like you hit the starter button once and bike fired right up!
Real satisfying watching
That’s what actually happened I guess I was lucky
Thank you Very useful
Thanks enjoyed doing it.
Thanks for being interested
A great outcome,l noticed you didn't have to up jet carburator,all good.👍
Thanks for watching

I will do my best, The wife insists on a holiday next, once paid for the next project will appear.

Would love to see an update of how it rides once you've ran it in!
Colineire should be able to put up a first ride later today
Kept the same carb and jets it seems to run fine, it does spit a bit on over run sounds great.
I have had no overheating issues however I have not had a long top speed run as yet.
Do you know the part number for the spark plug I have a suzuki extreme baja 300 that I bought with a bad head I replaced the head but the plug the old head had was not the correct one for it
Hello,Mark. Great work. What kind of handlebar do you habe?
did you keep the same carb? or is it the 300 also?
Glad you are finding them useful and thanks for commenting.
Great vids Mark, very good. Quick question, what tires do you have?
Top speed? How much is the price of the 300ccm big bore?
Nice job 😊👍
Daniel Podwinski I paid £150.00 including delivery on e bay. Have not done top speed as still running in.
Will the clutch handle the extra power...
Good question, I replaced the clutch and installed heavy duty springs that are available on e bay, works fine.

Голова на 2 клапана лучше чем голова на 4 клапана?
