Replacing my head gasket, had the head skimmed, what I need to know is about retorque. I saw some people say it needs to be done after its been run, However my manual doesn't say a thing about it. Im useing a factory yamaha gasket. What's the skinny?

I may be interested. Send a pm

heard back from Ferrea, they are in fact the same valve and ferrea makes a roadracing valve for the intake and exaust. these are way stronger than factory, pn F0110 is the exaust valve and F0109 is the intake valve in Ferreas cataloge and both are made inhouse. now im off to build a head.....

Don, i kinda figured that may be the case, i ordered a nos fzr valve on fleabay to mic and get exact specs, im still waiting to hear back from Ferrea. i will update as i find new info

Anyone know the specs on the 2?? Are they the same? The part numbers are bugger close 3he 12111 00 vs, 4jh 12111 00. Ferrea makes a yzf valve. I'm trying to get a set.

I was curious as I was told my pirelli diablo rosso corsa 120/70 was "pinched" and causing the tires peaked profile to round.

Hello all, new guy to the forum. Just started racing my fzr600r this year in alaska. Anyone know what has to be done to fit a yzf600r rim to the front of an fzr600?
