Message: [QUOTE="dirt bike dave, post: 1330293, member: 18302"] Check to see if the exhaust is clogged up. It's doubtful that it has a rebuildable silencer, but years and years of running rich could have gummed up the pipe. Make sure the fuel tank is venting properly (under load you need to suck in more fuel, and if the tank vents are clogged it can restrict fuel flow). If there is a fuel filter in the fuel line, remove it or replace it with a new one. Make sure the petc*oc*k inside the fuel tank is not clogged with debris. Is the air filter clean and not over-oiled? Does the bike pull strong and rev out in the lower gears and just peter out in top gear, or is it weak in every gear? How many mph will it top out at in 4th gear? Will it pull in top gear if you slowly and steadily give it more throttle? Does it only bog if you whack the throttle wide open? [/QUOTE]
