I'll keep you all informed. I'm having a 30 tooth installed Friday.

After having the 30 tooth installed, I found out two things:
Yes, you can feel the difference. The bike has more pep. I have not yet found myself shifting any more or less than usual.
It does throw the speedometer off. The faster you go the greater the difference. While cruising at 60 MPHaccording to thespeedometer, my Garmin shows the speed at 55 MPH.

 

I called and talked with Baker, they do not have anything in the works right now for a 32 tooth engine sprocket. Revolution Industries does have a 30 tooth, but it replaces the complete compensator assembly, end result, being a direct drive from the engine to the trans. That pulley does come with a shorter chain to match and is $295.00. The stock final ration on the FLH's is 2.79:1. With a 32 tooth engine sprocket it goes to 2.97:1 and with a 30 tooth, goes to 3.15:1. I am waiting for a 32. I also talked with Primo and they are in the development stage of a new engine sprocket, but it is not yet available, but from what I was told, it would retain the compensator assembly.

Changing the trans pulley is not the way to go, IMO as it is costly, needs a new belt, and you mustpull the swingarm and primary to install, along with recalibrating the speedo. The engine sprocket is a quick change, pull the primary is all.

The other alternative would be up one on the trans sprocket and down one on the engine sprocket, would not require a new primary chain, but I know of no-one that has that in the works.

 

I talked with Bobby Woods the other day.He recommends changing the tall gearing on the 2007/08 dressers from 2.79 to 3.15 by using a stock(1 1/8inch) 70 tooth rear pulley from a 2006 dresser & a Andrews 30 tooth trans pulley.This change will require a speedo recalibration unit to get the correct speedo reading,but the stock belt can be used.My question:Has anyone here tried this?I think it would be a very nice improvement.Thanks in advance.Regards,Tom

 

I ordered a SIM 1 dakota digital speedo calibrator,Andrews 30 tooth trans pulley # 290306 & a HD 70 tooth rear pulley # 40217-04 for my 2.79 to 3.15 gear change.I will update after completion.Regards,Tom

 

I have a 3.15 final gearing by going with the 30 tooth EVO Ind. engine sprocket. Yes, it does eliminate the compensator but so far I have not encountered any negatives doing it this way. Just got off the highway an hour ago, 350 miles at 70mph. 2900 rpm at 70 so not excessive at all. And much better pulling away from a light, and easily in 6th at 55 if I want to be.

Best "basic" mod for 07-08

 

WTF? If I wanted to do that I would have bought a Gold Wing....[8D]
