Last year I had problems with my RX-1 shorty no backshifting properly. What would happen every now and then was the following: upon trying to move the sled from a dead stop, there would be a tremendous squealing noise from the clutch with very sluggish movement. When I stopped to take a look at the clutch, I found the belt sitting low in the secondary. I would expect this condition from a hard stop (track locked) but I know that I coasted to a stop before some of these events. I took the secondary apart today (going on a 5 day trip tomorrow) and measured the spring. The spring has a pink mark, the spring wire is 6 mm in dia. but is 6 mm short of the spec free length, 69 mm vs the spec of 75 mm. Another rider posted similar a similar condition here a few weeks ago. Now my question: Can I just wind the secondary tighter with this spring to get better backshifting? If so what should I try. Right now I have it set at holes 1 and 6 (70 deg.) versus the stock 3-3 (60 deg). All help is appreciated, leaving at noon tomorrow. Thanks

I always found mine to work better at 90-100 degrees. Is your inner shaft clean and smooth and the bushing ok? I have seen belt residue build up on the shaft and not move smoothly. Take it apart and use fine steel wool on the shaft and bushing to polish them.

set it at 80
you should be using a different spring-try the silver one-ive found it to work best
or anythink but the pink one
the pink one will coil bind at full shift
if youre goin past stanfordville stop by ill give you another spring

Toolman and Dynarex,
Thank you very much for your quick responses and advice. When I disassembled the secdondary today, I throughly cleaned all the parts removing all the accumulated belt dust (4400 miles worth). I lightly polished the the bushing on the helix and the half of the pulley. I cleaned the small amount of residue off of the shaft also. I polished the the ramps on the helix, they were a little rough. The buttons look fine, only small flat spots have worn into them. When I assembled it, I set the helix to 70 degrees but tomorrow I crank up to 80 or above. I'll planning on buying a new spring. Should any lubricant be used? In the past I have used a VERY, VERY light coating of Moly disulfide which ends up being a dry film. Would you reccomend a multiangle helix?

dont use any lube-just hot soapy water to clean
its already a muti angled helix
id concentrate on the primary before the secondary for performance
you dont need a new spring but there are better ones to get
