I just bought a used Ulmer stage 2 clutch kit, and there re no numbers on the spring holes. Which hole do i use? The instructions show I should use the # 6 hole....any suggestions?
 
Bigsur,
Please enter your location in your site profile, per site rules.
Try Contacting Allen Ulmer. Even though you bought it used, Allen is a class act, and has excellent customer service. I'm sure he'd be glad to point you in the right direction.
 
x2 or 6 and 2 if the conditions are good and hard. Allen, told me 99 pecent of his kits are set at 6-3.
 
Funny I have a Hauk helix in my sled I bought the sled used and cant find any numbers to indicate the ramp angle of the helix. Does anyone know where the numbers are on the helix
 
The numbers for the Spring Twist are on the Secondary Sheave versus the helix. Have not seen a Secondary yet w/o the numbers cast right in the sheave.

And, I would check with Allen on the correct Secondary Spring Twist setting. I suspect that the setting would depend on the Secondary Spring you have, and we have not heard anything about that yet, unless I missed that.
 
I guess we need clarification on which part has no holes labeled, the helix or the clutch casting. I know some of the castings have reportedly been getting a little hard to read.....
 
I just installed a ulmer kit in a nytro and the where no casting numbers on the secondary itself.
 
I was able to look at the Ulmer instructions and figure out which hole was which, and they also the same as the stock helix. After installing the clutch kit, it was a night and day difference riding the sled. Engine breaking i all but eliminated, and it takes off out of the hole like a rocket. Backshifting is perfect....I would recommend anyone with an Apex should get the Ulmer Stage 2.
