Newer twincam cruisedrive gearset in early cruisedrive case.

I have a customer with an 07 that has VERY excessive whine in 5th gear and I have been considering just swapping out to a newer gearset that uses a helical 5th. Are there any pitfalls in doing this?

IIRC there was something about a DT flash (M1330) when going from the straight cut 5th to a helical 5th, but that was the only issue.

Is it an 07 Bagger? I had one and the 5 gear whine drove me nuts. Installing the ids brought that racket down to a tolerable level.

I have an '07, and remember all the noisy 5th gear posts. Harley came out with the IDS (cush drive on rear wheel) on the '08's that retrofit '07's. I don't remember the details, but it was as much harmonic noise as gearset noise?  I think I bookmarked it here. Will try to find it later.

The new gear set drops in. In fact the old one supersedes to the new one. The bearing collar for the inner primary bearing is different. You need to flash a different speedo calibration in, TTS or PV no problem. Back in 2010 i bought the individual parts to do it on my 09.
