Ive never had a Vesrah fail on me before, but theres always gonna be a bad one no matter how good the company is. Pop off the head and take a look, you might also have a groove in the head the waters seeping through?? Also, is the water gushing out, or is it kinda more like a small leak? And how many bolts is it coming from??

try a little silver seal in the fluid..I have had to do that on a few R motors that didn't have acorn nuts..they like to weep out of the stud hole.. 1/4 tube that it.. let it idle

Hey raffa, have you ever tried the oem 83 yz 250k head gasket? They are direct bolt ons and save ya $11 over the oem tri-z. It isn't multi layer sheet like the tri-z. For some reason they didn't feel it was needed on the bike? I don't waste my money on the oem tri-z gaskets anymore.

thats a bike gasket.. the fiber one. OEM are metal.

I have 2 of them bike gaskets .. have allways used metal ... oem and aftermarket.. never had a head gaskit go bad.. like I said use some of that silver seal ..if that dont do it,, them pull the head!

was the surface clean? them fiber gaskets like to become part of the cylinder,


the 83 gasket is .60 uncrunched
the tri-z is .40 uncrunshed


20tho diffrence.. that will do wonders for your compression..NOT!:eek:
