Does anyone know the correct valve clearance for the gy6 150? Is the "A" version spec the same as the "B" version? I've searched several sites and the specs are all different.

I guess, since I have a Carbide too, it would be the same on mine too?

The gy6 valve specs should be .003" intake and .005" exhaust. These are the best clearances I found to give top performance. TOM

I have read the manuals and some engg books, Most of all suggest .003 to .004 is good, some also suggest that it should be .001 for best results, you can look for what suites you best.....
