I was wondering if anyone was running an opticool gasket on a mountain viper and wether it messes up your squish band? I'm just about to put one in my viper and I've stalled because I've heard that it decreases the squish reducing power in the mountains. I'm riding 6000 to 10000ft with a stock mountain viper. A yamaha mechanic told me that cooling is not an issue at the altitudes here in MT. I believe he was refering to lower temps compaired to flatland sleds. Another idea I was thinking about was taking the center gasket out.
Any ideas on this are welcomed. Thanks.

I would love to hear some ideas on this issue as well, I overheated my viper on multiple passes up a big hill in 2 ft of pow at 10k last year and I know its a combination of things including head cooling. I am about to tear mine apart as well. Anybody?
mtn,
I ended up using an opticool gasket but without the center gasket. I didn't measure squish but I did measure the opticool gaskets and compared them to the stock viper gasket. Without the center gasket it seemed like the opticool was about the same as the standard viper gasket. The whole opticool was slightly thicker. So I went with removing the center gasket.
