Intermittent Slapping?

As I was riding my bike around today, I noticed that sometimes when I decelerated there was a strange Knock and or Slapping noise, It happened at Intermittent times but was always around 2.5-3 RPM, The bike is running fine, no drop in power or anything like that, just the Knock and or slapping when I decelerate, It almost sounds like a chain but my Drive chain is fine, could it possibly be the Primary chain you think?

That's all right, I get that a lot.. There's a reason I can only go to one mechanic all the way in Pasadena, he's the only one that'll work on it..

I plan on taking the bike back up there this weekend anyway, it's time to have a valve clearance check.

I hear intermittent slapping when I do jumping jacks in my backyard in the nude. Probably not the noise you heard unless your my neighbor.

For what its worth, I had a old car early 70's Chrysler V8 engine, it started doing a similar thing. Well more of a ticking but it was a car = engine further way from ear Turned out to be worn valve guide. No noticable power loss and only ocurred in a limited RPM range on deacceleration.

Make sure your drive chain is adjusted and lubed.

If that's o.k. It may be your cam chain.
Your cam chain adjuster is not automatic like newer bikes and it may need adjusting.
Depending on if you still have the original or not you'll want to check/adjust it.

Remove the right side engine ignition cover.
Slowly turn the engine over clockwise with a 17mm socket while looking at the timing plate.
Just after the 2-3 timing marks pass the timing marker you'll see the plate has a corner where it turns from curved to flat. Right at this point stop turning with this corner at the timing mark.
Use a 10mm wrench to loosen the jam nut on the tensioner adjust bolt, it's at tue rear of tje cylinder.
Loosen the bolt a turn and then tighten the bolt, (just snug) tighten the jam nut and reinstall your cover.

If you have an APE tensioner it's a bit different. Here's a good write up of one:

Hope this helps.
