Thanks for the honest reply max, a little worried about losing that bottom end. Rode a 850 boost it kit and they mentioned that they were waiting for stronger spring and heavier weights to get clutching cleaned up a bit.

I have t played with the pdrive springs yet. Got a couple on order that I'll try that I think will help a lot.

Just got the word this morning that all the authorizations have finally come through to rebuild my Son's sled from the insurance agency. And they are putting all the new parts back on today!

SHR has the MPI kit pretty dialed in for anything above 5000'...
Working on low elevation set up now...
SHR base line clutch kit mandatory, anyone running stock summit weights are missing about 20 hp to the track...
SHR has "in the sled" adjustable weights, exceeds any other as for ease of tune and getting the weight where its required-BJ

We have 1 kit left in stock...
