I'll take it. As a child of the 60's, I'm used to long rambling dissertations on not much at all, album covers for example. (No offence Catch)

Flash and exhaust have been on the bike for approx 4,000 miles.

One ride I noticed that it was popping a bit on decel. If I ran through a gear hard and cut the throttle it would occasionally backfire.

Seemed to do it mostly in the midrange (5-8k)

Ran like that for around 300 miles and just last night I noticed it wasn't doing it at all. Completely back to normal??


When it was acting up, everything else felt fine. Full power, started right up, idle was good.


I checked for an obvious exhaust leak, but header bolts were fine and muffler was secure.

It started in the middle of a tank of gas, and ended in the middle....with about 3 tanks through it.


I'm not sure what to think of it. Fuel filter perhaps?
I had similiar problem changed the oil and it fixed it. In thinking because i have a small oil leak in clutch cover from previous owners crash it got a little low but i dont know why this would nake it pop and backfire alot

i spent some time thinking about the low oil and crack in the clutch cover

to have popping you need two ingredients. Unburnt fuel ( normal on closed throttle) and fresh air. The fresh air is normally what the ais system provides on closed throttle to clean up emissions

I guess its possible if the oil level got below the crack in the clutch cover it started to suck air in, though i would have thought it would blow out
