My Gen3 made 200HP yesterday on the same dyno as MCN's 194HP Gen5 did with system & flash :surprise: But obviously with a few more mods than just a system & flash :crackup::crackup:

impressive torque curve on a gen 3, those compression mods really help in this area. should pull hard right thru gear changes. nice work.

Good power that. Id be a bit worried about reliability with high compression. Do you know what the compression is? I skim heads at work but .3 is alot to take off

I don't want race fuel it's so expensive although it would be interesting too see what happens. No video I should have done I know, 900grams of the crank it spins so much better much much better, well worth it if your splitting the case anyway.

It's running fine no heat issues so far, rod stretch Kawasaki say 0.06mm Iv got all clearances down to minimums, checked the old fashioned way using clay, it's been smashed off the limiter plenty times on dyno & no contact yet.

if michael refering to .3mm thats about .012 inch. if u do a cnc valve job and valve unshrouding in the combustion chamber, takes about that to bring chamber back to stk. cc. i've decked ten heads as much as .025-.032 inch on stk piston bikes. good build skills on that measured tight piston to head, major factor in making big hp/torque.

The Woosner pistons are just absolute PORN to work with just look at em.:x
