310 kit with stock 34mm carb? Boring the carb?

[250r'en +TCB]

After the summer/fall season has ended I plan on getting an ESR "econo 310 kit". It's the $799 dollar one in here http://www.esr250.com/cylinder_kits.htm#esrbolton

My question is, Can I keep my 34mm carb on the 310cc engine for a little while, just till I get my 38mm carb down the road???? Will a 310R run on a 34mm carb???
Thanks, Devin

If you are going to invest $800 into a 310 kit, my opinion is that you should spend the extra $100 and get a bigger carb. The 310 kit would be pointless without a bigger carb. You would have to rejet your current carb for the 310 kit, and it wouldn't make anywhere near the power it should..

Is it possible to shave the intake side of the carb (like the cylinder) to get a couple more mm out of it????

You can have a carb bored out, not sure how far you can go though....

Buy a 38mm carb NOW, it will give you a good boost. They you'll be set when you upgrade to the 310 IMO.:beer

yeah but I am kinda planning on getting the 310kit first, then the carb later.
If I bore the STOCK 34MM carb how big can I go????? Does anybody know or have any expierence with doing this???

Well that's like "wipe'n before ya POOP"! :lol:

I've had car TBs borred out, on a lathe with nice precision, a few mm's but theres much more meat on those. Then you need to make sure the slide still fits right (had to make new butterflys for the TBs). I wouldn't mess around with a bike carb. Too much work and too easy to screw up IMO.

^^^ hahahaha thanks for the interesting interpritation!!!!

Anyway if I could bore it to like at least 36 I should be set for a while, then agian maybe I'll just post for one in the classifieds....

It is safe to go 2mm over, but like AZ250R said "its like wipin before you take a poop" lol, that is signature material right there.
