<font size="2" face="Verdana, Arial">Lapping the valves is when you us lapping compound (it is like a liquid sandpaper) to clean the valve seats (it makes a better seal and that = less compression leak) It doesnt really change the valve enough to messure it.Originally posted by 96Gixx7Fitty:
Hey john.. when you refer to laping the valves.. are you meaning to say you put new grind angles on them, or making them a little shorter?
<font size="2" face="Verdana, Arial">I took the center layer out of my stock head gasket and I didnt check the compression after.. I didnt check the clearance (like a dumb ass, but I was learning and trust what people on this site told me I could do).... 1500 miles later and a new head, block, rod, pistons, and having APE balance the crank, it cost me about 1500 bucks to do this motor...
Also, have you never seen an issue with valve clearance with a thinner head gasket, and has it upped your compression by much?
<font size="2" face="Verdana, Arial">Yes it is bad... if you want a thinner head gasket I would talk to Yosh. I know they make them for my bike but not sure about yours.Originally posted by 96Gixx7Fitty:
Ok John.. I sent you an email when I should have been reading your last posts here. But I have to know.. was it bad taking the center layer out of your head gasket? Did it indeed make the clearancing inadequate? hehe I guess that's one thing I'm asking.. or two things.
