Sweet I am so excited to learn a new style of riding, I am not worried about short shifts I will be able to feel when power is at peak and its time for another gear...so 2nd gear ? 1st everytime for racing up a sand dune hill? Most of my racing starts off you going down a quick slope then a long climb up a semi-steep dune.. I will have paddles....ill mess around with air pressure...I will short shift...2nd gear start....what about the sprocket now? What does the sprocket do and whats its purpose as far as making changes? Smaller = more torque / less top end? I want more low end power I am not concerned about top end.
Front sprocket
13T -5 mph
14T stock
15T +5 mph
Rear
36 +3.2 mph
37 +1.6 mph
38 stock
39 -1.6 mph
40 -3.8 mph
Gearing is all dependant on tire selection, tire rollout, # of paddles, tire pressure, sand conditions, rider skill, rider weight, swing arm length, elevation & quad HP. I'm not a sand guy but playing with tire psi & gearing should get you closer to being dialed in. Front sprockets are cheap, I'd buy 2 different sprockets & test them all in the same day to feel the difference & what you like.
Beware of PMS
Powerstroke Modification Syndrome ( It will cost you thousands of dollars 
)
Do you think you could post this in the 700 modifications area?
I think this would be great for people with gearing questions. I'll sticky it!
Great post!
