all you have to do is order a 426 piston from je and have teh cylinder bored to match. i have been running this for a couple years with great results.

i dont no about je i havent heard much on them are they as good as wiseco? and were did you get that 13:5 comp ratio just wondering i want a 12 or 11. thanks

all i run are je pistons after a complete cotastrophy with a 465 wiseco. the piston failed ripped the bottom skirt off and destroyed everything. anyways if you are gonna run the 12:1 you will have to run high race octane so make it worth your while and run the 13:1 je. i have the head decked for more compression. the 13:1 makes great torque.

but were did you get it? and is it fast can you beet a stock 450

[SHADETREE101]

it was from ken's cycles. but i will say that he stood behind his product and rebuilt the whole engine. i can kill a stock 450r. even with quite a bit of mods i run away from them. but you have to run alcohol to get that power. http://i18.photobucket.com/albums/b118/shadetree101/iwin.jpg sorry about the blurr.

i have a JE 11:1 426, great power and reliability. the only problem i have had is headgaskets. i replaced it twice before going with a cometic flex-steel gasket and have had no problems since. mine is still on the stock sleeve but wiseco makes a sleeve to use a 426 then go up to a 44o, but a stock sleeve is fine. contact C&D or a local shop to get the parts. a 426 is an 88mm bore, and stay below 12:1 if you want to run pump gas
