I think we would all need a bit more information to help out on this one. What does the noise sound like? Does it happen as soon as you start the bike, while at idle or at any one particular speed? Does it sound like it's coming from the top or bottom end? Just need some more data.

Thanks Dakotabos for PM and hot tip on Compensator Nut on front sprocket.

After researching and watching (listening to motors idle) on a few youtube videos, I think it is a loose Compensator Nut and/or worn Compensator; as you do...

(note: I have additional noise, from the left side primary case, like a bad bearing sound "rattleing" at 800 to 950 rpm, goes away at 1000 rpm -- that has been slowly steadily getting worse; along with the chirp on decelleration).

I will try the Compensator Nut first and let you know how that turns out this weekend.



Update Saturday 4-6-2013:
**ENGINE IDLE RATTLEING WAS FIXED:

found loose Compensator Nut; removed it with about 10 ft lbs. of torque!!!!, caught it before major damage... Removed, cleaned, retightened nut with High Heat Red Loctite to 150 ft lbs. **

Thanks to "Dakotabos" and "Woodbutcher" to send me down the right path.:2thumbs:

This video also convinced me of the potential fix since my "idle" rattleing noise was not quite as bad as this Harley; [which I believe also had a loose compensator nut, a somewhat common problem.

PS: "Chirp" (not heard in above videos and only occurs when riding) is from secondary belt against rear pulley. Temporarily fixed by spraying "Fuchs Pro-Prep Silkoline" spray on belt every other ride or 100 miles. Got a Teflon coated rear pulley will put on with new back tire soon that will fix it for good...

If there is one quick chirp when turning the throttle off, it may also be a bit loose belt.. often together with worn pulley..

Well my hair is not the best but it's a Clank Clank idle in neutral not moving and it seems to disappear at a higher idle seems to be coming from the bottom and near the rear cylinder any kind of test 2 recommend
