310 or 330?

[sarvas]

i need some help with figuring out wats the best for me. its my first rebuild. so i am thinking about throwing a big bore kit into my R. wondering if i should go with a 310 or 330 and how reliable each are. and ct or esr. and also wat size carb.

right now i got a 86 250r with a mid range pipe from ct and everything else stock. i just want to use it in the sand and show all those 450's out there up.

if someone could start me in the right direction that would help me a great deal. thanx

310's can be set up to be very fast cylinders. and would be easier on your tranny. Plus you have more bores with a 310 than a 330 (at least the bolt on) there is a cylinder that you have to have the cases milled out, but that costs more money. 330 obviously will have a lil more power.

I would reccommed the new esr 310 kit, 600 bucks comes with everything.
