Hey Hoping that someone can tell me what my Ulmer clutch kit should be set at on the secondary. On the video they say 6-1. In the instructions on the web site they say 6-3. I just installed used kit ( low miles) in my sled and now the thing is like a slingshot to 75mph and then 76... 77... 78... 79... 80... all the way to top out at 90. Right now, I am at 6-1 setting. Just to make things worse, I installed a pc3 and ign module at the same time (I know,always only ever do one change at a time). I also know someone is going to say , what was it reving at and I can't tell you right now because I could not take my eyes off the trail it was accelerating so fast. Anyway, I'll start by double checking all the clutch work and then next weekend see where it revs too as well as figure out the map switch. Thanks

The clutch setting will depend on the secondary spring used, which will depend on your mods & rider weight. If you bought the kit new there will be a sheet in your weight bag with the kit specs on it & it will tell you where to set the spring on that sheet.
