So the #3 and #4 valve guids are toast and the seat on 3 I am sure is garbage.:thumbd: Ordered a used head off of EBay yesterday and I cant wait untill it gets here. Bike still runs good she just birns a bit of oil and tics out the exhaust. hell I have a new head on its way so I am going to ride it to work still (being nice and gentle of course). And yest there is a little bit of a lac of power.
