Anyone know the color for the clutch spring to lower rpm engagement.
 
Schmidt bros has a nice set-up. Noticeable difference on my '13XTX compared to my '11SE.
 
How hard to install. What's so nice about the schmidt? setup

Smoother take off, can enter in and out of a garage without spinning the track. Doesn't annihilate the track as much out of the hole for better take-off. Not hard to install at all. I lost some top-mph with the Ulmer kit. Went to the Schimdt bros. and have a faster speed on the gauge. But then again, I also had them overdrive my primary, which may have been a big factor in that too. But as far as install, if you can turn a wrench, you can definitely install their setup.
 
I can turn a wrench just never did one.
 
Same improvements with the BOP spring for $20
 
i've got the spring as well as the clutch kit from Schmidt for my 2011 XTX. works good and the clutch kit has good strong mid-range pull but i was over revving by 150-200 rpms or so, so i added weight to the tips but haven't had a chance to try it again.

if just the spring is all you need then i would think the BOP spring would be a good option as well. seems to be a lot of people on here that have it and really like it as well.
 
Dumb question idk but what's the "BOP" spring?
