I haven't seen any recent inquiries on this setup

but do recall several inquiries going back a ways. I completed the conversion a couple of months ago and if there are still any inquiring minds; post away.

 

Hey djl,
How are you liking that TwistGear install? Any problems? Shifting improve? Less vibration in 5th with that helical gear? Do you feel a 6 speed would have been a better direction?
Looks like a solid product but I can't find much for write ups from people that have been running them.
Thanks!

 

You won't find many write ups; the old bullet proof five speeds have been superseded by the "coolness" of the six speed. I am one of those that has never seen the need for a six speed unless you are a long haul tourer that rolls up 15K-20K miles a year.

No problems so far after about 5K miles. Shifting may have improved a bit but I had not shifting issues before. I believe the Shockproof improves shifting as much as anything. I have never had issues finding neutral or any other shifting issues. Vibration? Never had any vibration in 5th gear before and certainly none now. I have two bikes, the other is a 2005 FXSTD and I will be upgrading the 95" motor in that one to 98" with better heads, longer cams and better exhaust this winter. I will very likely install the TG in that bike as well. There are occasions when I think about grabbing a sixth gear but the old five speed is just right for riding in the Texas hill country. What I am considering with the next install is going up a tooth on the trans pulley. With a motor making 110 or so TQ, that would give up a bit of the TQ multiplier gain in the first four gears but would drop cruise rpms about 150 or thereabouts. IMHO, much better combination than a six speed.

BTW, you've got mail.

 

Thanks DJL! Still on the fence with the pros/cons between 6 speed & TG. One thing that can't be denied is the reliability of the 5 speed. Those TG door bearings look pretty tough. Top that off with the fact I wouldn't have to change my current gearing just may push me to the TG side.
