I just installed a QSC/STM clutch setup on my 2014 Maverick XRS and was hoping to get help tuning them, here is some info about my set up.
QSC Primary:
Out of the box weight setup, tip-3/8" SS, center-1/4"SS, base-empty & cross hole- (2) 3/8"SS
Silver spring with blue strip and (2) aluminum shims behind the spring
STM Secondary:
40EB
Silver spring
(2) Fiber shims
Other info:
Again its a 2014 Maverick XRS with 29.5 tires, I live in Houston,TX so no elevation to worry about, I mainly mud/trail ride in low gear, everything else is stock.
The below video is with the "out of the box set up" which was: tip-3/8" SS, center-1/4"SS, base-empty & cross hole- (2) 3/8"SS
I emailed Adam at QSC this video and this is what he said "I would put the 1/4" SS from the center hole into the base hole and leave the center empty, also put a 1/4" SS in the tip instead of 3/8"SS. The severe drop in rpms at 36mph is from the primary going fully closed. This will always happen at full shift, high or low gears".
So as Adam suggested I changed my weight setup to : tip-1/4" SS, center-empty, base-1/4"SS & cross hole- (2) 3/8"SS. The below videos "setup #2" are of that setup, one was in low gear and one was in high.
Low gear "set up #2"
High gear "set up #2"
So now some questions:
1. What do you guys recommend me do to the weight setup after seeing these videos?
2. That severe rpm dropped around 36mph in low that Adam refers to as "shift out" is it suppose to do that?
3. I was told since I mainly mud/trail ride in low gear that I should do my tuning in low gear and not worry about tuning it in high. Does that sound right?
4. Also as you can see in the videos I lost a lot of mph, with the stock clutches it would do 45 mph in low and 76 mph in high. Is there a reason its such a severe loss in high?
Any advice or suggestions you have would be greatly appreciated.
