Cool Head switch to stock

[BitchenBanshee]

I currently have a cool head which I hate. I like to check the top end of my bike at least twice a year so I am frequently taking this head off. It seems that maybe 50% of the time I get a leak somewhere. Sometimes it seals fine. I would rather go to the stock style head, get it shaved, and never have to deal with these damn O-Rings again. The question is, I'm currently running 17cc domes. What would a .030 shave on a stock head compare to? Is .030 the most that can be shaved from a stock head?

 

thanks!

not tryin to be an ass but sounds to me like u are not puttin the head on wrong or somethin unless its a trinity stage 4 head cuz that mofo is just plain junk from day one we run pro-design heads on our drag bike as well as trail bike and hardly ever have a problem with them leaking or nething else. when u put the o-rings in the head do u use grease or sycilicon to hold the o-rings in place? u may be pinching a ring when puttin the head on and it not tearing completely until a lil way down the road

I agree with A&S, I'm using a P.D. Coolhead and I've had the head off at least 10 times and I'm still using the original o-rings, they've started to flatten out now, but still no leaks.

 

If you've made up your mind to go back to stock, 0.030 is the most you can take off the gasket sealing face with a straight cut. If you want to go more then you have to recut the combustion chamber to correct the squish band.

i have run both stock head and cool head on my bike and with the stock head the motor ran hotter than it does with the pd cool head beacuse the coolant flow is much better with the coolhead as appose to the stock head and when a motor is running cooler the better it will perform and last you. another thing make sure u torque the head nuts to specs and recheck them ever so often as well better safe than sorry

I agree, I've had a P.D. coolhead before and had problems (leaks)... now running a noss and it works great no leaks. I would think about switching to a noss, than going back to a moded stock.
