LT500R running out of fuel!
I have a 1990 LT500R and I can't seem to get it running properly. Paul Turner pipe with a Fat Boy 2 silencer, Keihn 39mmPWK Carb, .20 over Wiseco piston and rings. I run 32:1 Yamalube with 93 octane. It starts within 15 kicks when cold and immmediately after it is warmed up. It idles perfectly, and runs great in a wooded trail. When running on flat ground, it seems to want to sputter slightly from half throttle up to full throttle, and while winding out fourth and, or fifth gear,(at full throttle only) it seems to run out of fuel. It doesn't shut off, but it loses all power till I let off to regain fuel in the bowl(so it seems).Any Ideas?????????
