Moderator Airhead Posted May 30, 2014 Moderator Posted May 30, 2014 the head gasket is duff, you shouldnt be using it like this or you risk damaging the head. Buy genuine yamaha gasket, aftermarket options are often crap
alfotuning Posted May 30, 2014 Author Posted May 30, 2014 Its genuine !!!! Head gaskets all other are Athena but head is genuine !
Moderator Airhead Posted May 30, 2014 Moderator Posted May 30, 2014 err the head gasket is leaking....you hearing this? 1
slice Posted May 31, 2014 Posted May 31, 2014 Hi Alf, you need to hear this mate, your head gasket is leaking as Airhead says, not the rad cap or anything else just test the bolts to see if they are done up to the right torque. If they are then you have another problem, your best bet is to whip it off and have a look to see if it's ok but whatever it is you have to take it apart mate.

alfotuning Posted May 31, 2014 Author Posted May 31, 2014 its done 4000 miles with leak another week ill have 170 kit so all be changed so doesn't matter
alfotuning Posted June 1, 2014 Author Posted June 1, 2014 but what makes a head gasket leak? i do rag the shit outta it ?
Moderator Airhead Posted June 1, 2014 Moderator Posted June 1, 2014 could be a number of reasons of course,damaged gasket, bolts not torqued evenly to specification, a crappy gasket (your is a genuine one I know), faces not cleaned properly before the gasket was fitted, warped cylinder head, even a cracked head.
slice Posted June 1, 2014 Posted June 1, 2014 Well that says it all really, if you scream the shit out of it it's gunna blow, unless you work on it on a regular basis then it will throw more than the head gasket, expect to have a visit from the piston soon it will visit via the side of the cylinder
alfotuning Posted June 1, 2014 Author Posted June 1, 2014 its in bits piston looks like new so does bore although a bit of water in there. i took head of and over tightened thermosta bolts and now wont do up. oops. so its in bits now untill Athena kits get on. also looking at spark plug its a light brown its jetting to big 230 jet thanks
