engine noise
Hello again. Fusionking topcat and marty. just got bike back together, took out for a ride. runs pretty good tooling around town.Got out on interstate noise happens when you hammer the throttle,noise is there emidiately all the way to top end. If you ease into throttle barely any noise at all. I'm not using indy filters but a uni filter similair to stock filter but made out of foam, and uses oil treatment to trap dirt. I did notice slight popping in exaust at idle but not under load. pulled cover off ignition adv unit.put timing light on it at idle timing is on the money not sure about full advance timing light won't work at that high rpm for some odd reason.forgot popping in exhaust seems to be #4 carb adjust idle mix screw will go away.I did check engine temp at exhaust pipes only 20-30 degrees diff in pipe temp. On nother note vac adv unit feels ok by hand moves freely .vac hose holds vac. motor has 28k on it. valves a little noisy. Do need to adjust. maybe there is something mechanical like vac adv chatter or sloppy chain. need to check comp. I do very much appriciate all your in put and advice. gives me things to look at. Once again thanks to everybody for the great advice.
