I've been running a GGB mountain can for the last 600 miles and it has been phenomenal. Weighed the stock can and the GGB can, there's a loss of 11 lbs.

Warranty

sorry guys, been a tad bizy around here...

posted a few of these tips on social media but here is what I recommend...

1) remove all felt bs (keep 1 piece under air box)
2) cut lower half clutch guard off (below belt holder)
3) add DIY 2" hot air exhaust vents on back of each side panel
4) clean clutches if new, clean clutches if not new
5) high altitude only (7000-10+) keep std mtn pin 16.7 gram and add a doo 417127039 qrs spring, 7800-7900 rpm MAX!!!!!@!!!!!!!
6) ANY elevation BELOW 7000' needs a heavier pin, use goodwin performance heavy pin kit....
19 grams 5-8000
21 grams 3-6000
24 grams 0-3000
use clickers 2-3-4 as needed if there is an over lap of elevation...
7) did I mention 7800-7900 rpm MAX???!!!
8) ALL 2.5" track sleds gear UP 1 tooth on top
9) any lighter fellas (under 180 lbs) on a 3" track could gear up 1 also but the above clutching is required
10) you take a break?? open your panels and give sled a break...

I have a stage 2 hi/low clutch kit in the works with new ramps but still not ironed out...

I am also waiting for the MPI turbo kit and have a solid clutch/gear combo waiting...

stone obvious stuff, keep belt, track and chain adjusted properly (tighter is better than looser)...BJ

How much of this compromises warranty

I still don't get the clutching from these French so called sledders you think they could get it fairly close for 13500$. Maybe weights and springs should be optional and let dealer decide where sled needs to be set for operation.
