best big bore kit

what is the best big bore kit

[honda400ex2003]

"Kit" is tough unless you go with a company

piston itself
JE and Wiseco get the tie for first. they are the main two that have 440s.

the CPs arent bad either.

I guess it would depend on how big of a bore you are looking for though. to me 440 is a big bore. others 460 is big bore then you gotta get a hot rods or the specific manu piston to run their crank or have it modded to fit. lol. steve

What size piston does the 460 stroker kit use?

[Dobber]

i believe its a 89mm piston and a +4 crank

[honda400ex2003]

you are correct! steve

My big bore kit is the best, that's who.....JK...wiseco no issue's yet,

i have a 440 12.5 comp. wiseco stage 2 hot cam 450r carb. and a 450 t/c and she dose the job for what we do. and we are now spraying (nos) and it is still strong for now. we are spraying a dry shot (15hp) but going to wet shot (20hp) so the 440 is good.

im also running the wiseco 12.5:1 440 and haven't had any problems with it since the rebuild.
