ok so i just got done rebulding my yz85 today new topend gasket set all that stuff i was riding it all good and dandy until i decided to jet it pretty much close to spot on as i could when switched to a 45 pilot it was wicked and then when i went to a 42 i loved the band even more but just recently out of know where it started to leak out the weep hole on the water pump and i read around here and i found out that when i start the bike without the cap on it swirls and all that but it has bubbles in it does that mean my gaskets up top blew?

That bike uses a rubber o-ring for a head gasket.. Simple fix...

Plus, you might want to have a look at the water pump seal.

Hmmm.. I don't think you should put the grease on the head gaskets...

it had came with a little slip that said they needed to be greased with lintuhum or what ever its called but just for the o rings? im about to take it apart right now, what could have caused this?and does it automatically damage your top end?

Did you torque the topend or just do it by feel?

another thing the top end gaskets it came with where just kind of like round the stock ones on the bottem had a flat surface and thats how you installed them could i have used the wrong gasket?
it is a gasket set for a 2002-2005 yz85?, but im going to get the stock head gaskets from bike bandit, when i tear down the water pump whats useally a FULL rebuild for it? i dont want it to fail or something again because i didnt replace something i didnt know i was sapoused too?
