I have got my 87 Lt500 put together and running from a ground up build. First it ran like absolute crap. I blamed 25 yo carb and got a 40mm keihin. Now when you blip the throttle it stays high a sec then comes down. I'm pos its the pilot is lean but wondering if anyone has encountered such issues.

 

Try suzukiquadracerhq.com lots of LT500 discussed there.

 

You slumming again erbe?
