Base Gasket Blowing out
Base Gasket Blowing out
had part of the base gasket blow out yesterday on my 85' CR500.. all the cylinder nuts were tight but it still blew a small section out of the left side.. the lower cases and cylinder is already dimpled to hold the gasket in place.. this happen to alot of these bikes? im thinking of maybe using an adhesive on the new base gasket?

Then call his ass up, Rosty knows his shit on these.abrracing wrote:the base gasket was a moose racing gasket. I read in another thread roostius recommended the cometic metal gasket.. i was going to order one today if I knew the exact one to get.

Thanks Jay, the cometic gasket comes in every Cometic and Wiseco head set for 1989-01 motors. C7020 and W5223 are their part numbers.
The material is aluminum with a sticky coating on both sides. The reed gasket and the base gasket are made of the same material and are .012" thick.

thanks for the reply Roostius.. My bike is an 85' so is there a metal available for that? aren't the base gaskets the same for the 500's ??Roostius_Maximus wrote:Thanks Jay, the cometic gasket comes in every Cometic and Wiseco head set for 1989-01 motors. C7020 and W5223 are their part numbers.

The base gasket is the same 1984-01. You can use everything but the head gasket.

Looks like it would add a little bit to the equation and maybe prevent an air leak.
My old Yamaha vintage bikes don't use a case gasket, just a coating of Yamabond.
Funny, they do use a base gasket though and I have added Yamabond before dropping the cylinder on.
I've also added Yamabond to the intakes too.
Was thinking of doing it to my '85 when I saw this post yesterday.

I had the same problem on my 500. Cometic gaskets are the way to go, no problems since
