I have a 53 deg. helix on my sled right now. What woiuld be the advantage in dropping down to a 51 or 49 deg helix?

slower up shift,but more operating rpm.due to not loading the motor as hard, it would be better for deep snow,and better back shift in the trails

Other issue revolves around spinning. If you can hook it hard, the quicker angle will give you better acceleration. Less angle etc..

I have 192 studs in it. Not much of a spinning problem. Just slow out of the hole. Really good top end though.

Are you pulling good rpm out of the hole? Is it loading up too fast? Try tighening the secondary a bit, sound like it's pulling the front wieght ok on the big end. The steep helix should launch you harder if it's biting
192 for a 600 will lots of studs. Good rule is a stud /hp, better to be more than less.

Here what is going on. I bought the sled for the wife. I had the clutch kick in at 3800 with no studs.(she did not like the jerk with the higher rmp spring.) My nephew also rides it. When he hammers on it I can not reach the power band fast enough. Real bad bog. After it hits about the 6200-6500 mark, hold on. I have the spring to kick in at 5200 I just don't want to change it every couple of days. Was hoping for a faster power band but minimal jerk on the take off for the wife. Any ideas other than leave her home?
