As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • This forum is for placing reviews for parts, accessories, gear and service as it relates to your GS motorcycle. The key here is "GS Related". There is a bit of latitude here but we don't want to see a review on Maytag washers just because that's what you use to clean your riding jacket in.

    Keep your review as factual as possible and please refrain from personal attacks. Posted articles will be reviewed by the Editors and may be removed at their discretion.

    So let's make this a useful addition to the forum! A special pat on the back goes to Hap Call for coming up with this great idea.

Vesrah Gasket Set Failure

Next head gasket I buy will be OEM Suzuki.

We should be so lucky; with an 1166 kit the OEM gasket bore opening are too small (1166cc 75mm v.s. Stock 72mm). :(

Maybe Katman will come along and tell the story he told me. He worked directly with a Cometic Engineer to find a solution to his head gasket issues. After supplying more than 1 special order gasket the engineer finally conceeded that they (Cometic) could not solve the problem (tooling issues). :-# I'm pretty sure we are talking MLS gaskets here.
 
Wouldn't the stock 1150 gasket be a viable option? Their bores are 74 mm and usually gaskets are manufactured slightly larger around the bore than the actual bore size.

I haven't seen an 1150 gasket yet, so I'm just speculating at this point!! I know that this is the case with the 8 valve engines.

The 1150 gasket bore hole is rather "square"ish, and so it exceeds the 75mm diameter for most of the 1166 piston, but at the flats it protrudes into the combustion chamber and would need trimming. Ray does this mod with sharp snips.

The unmodified 1150 OEM gasket would probaly be fine for the 1133cc +2mm pistons.

So what gasket did you use then?

Old style Cometic, composite sprayed with a little Copper Coat; retorque at 50 miles and at 4000 miles no issues not a drop of oil as far as I can tell. :-\\\

The base gasket was never changed despite the three MLS retorques and the head removal for the composite gasket. :o
