Thanks Alley, I had to drop down to a #115 jet and its running just a touch fat. But I'm going to leave it at that, I live in Tucson Az. So the engine gets a lot of heat off the road. Thanks again

Ok my gy6 150, I did aBBK 170cc, 30mm carb with 125 main jet and uni filter. big valve head, I had a 4mm stroker crank installed but have gone back to the stock crank. (Didn't like the vibration). I have an A9 cam. and a high flow exhaust. It excellerates great to 1/2 throttle, then falls on its face, till I back off, I can get to full throttle but real slowly, a little at a time. So am I needing more jet? less jet?

What would cause the starter clutch to come loose? I used an impact driver to install it. What would be the tourq spec for that nut.(

It turns out the valves was not the noise source. The stroker set up even with 3 base gaskets let the piston just touch the head. Not enough to feel or hear when turned by hand. But when running I could hear a ticking. I tore it down last night and used a dremel to champher the piston .015 and I even touched up the valve releifs. Should have it back in the scoot tonight.

With a a9 cam now I have a lot of valve clatter. Is this normal? The rockers are set at .oo35 .I also installed a 170cc BBK and 4mm stroker crank. I used 3 base gaskets to clearance the piston.
