Did a search and came up with nothing. My cousin has the bike with the issue, it sounds like a "turbo" spooling up in the primary. We had a new bearings pressed into the clutch spool and the inner primary for the transmission shaft. The bearing for the clutch spool was noisy, so we thought we found the problem and reassembled. Fired it up and "turbo" noise is still there. Looking for any input/ thoughts on what may be the issue. Thanks in advance.

 

Loose chain adjuster. It's a 16. Let the dealer fix it.

 

+1 That's what the warranty is for.

 

If it's only in first gear it's normal.

 

Does the noise follow the engine RPM's or the drive wheel?

 

It's a 15, I miss titled the thread, 3 months out of warranty.

Follows the RPM's.

 

Tore it back apart. Think it may be a chain issue. Lots of play forward and back and the adjuster was near the top end. Sprockets front and rear are running true, so I'll let you know when the new chain arrives if this solves the issue.

 

My 11 did that. That's why I said chain. Don't waste time with another Harley adjuster. Get the Baker Attitude Adjuster. I put it in my 11 and away went the noise.

 

Update: It was the primary chain, it stretched approximately 3/8 - 1/2 inch. Installed the new one and no more noise. Next project tire shredder kit and finish the powder coat! All the parts are in the garage and tear down starts Friday.
