Ohton Racing shaved 80 thousandths of mine and I still run 92 octane fuel.

 

You can shave 70-80 thou off a stock head. After that you end up breaking through the water jacket. Then just cut into the dome 10 thousandths to get the necessary squish clearance. It will only bring you up to about 160lbs compression so you can still run pump gas.

 

i sent it away to get 20 thou taken off, should i get more? by the way im buying a raptor for motocross, what do u guys think, love the 'shee but i used to own a '88 250r and LOVED the way it handled compared to the 'shee.. hoping to have my blk/white raptor in a month or so {i work at a yamaha shop} thx for the replies guys>> im new at posting here been reading forum for about 5-6 months now...
