137 ltx se heavily studded big venom kit with new orange spring over rev hits limiter 6 to 8 times added all i can to heel put another washer on mid fine on ice real bad on snow set back to 2/3 is it possible to much rear spring for n/a with air box mod only
 
What orange spring primary or secondary? Also do
You mean limiter on launch or top speed running?
 
Had the same problem regardless of set up finally went to gates belt and solved problem. I think the yamaha belts are too hard and slip at low ratios.
 
Why did you change the secondary spring in the first place? What was wrong with what you had?
 
No slippage here, stock pink spring at 60 wrap with washers underneath. I don't even think I should try this orange spring, it seems this unit is just to stiff. Made more for boosted sleds.
 
700 flawless ski lifting miles so far this year with TP orange secondary 3-3 on 5 psi turbo viper, running last year's gates cf 8dn length belt with over 1600 miles on it
:sled2:
 
Belt choice and helix angles I believe play a big role in spring choices. What works for one may not work for all. I see on sidewinder side a lot of talk about this and they really have issues with tune ranges and different helix manufactures.
 
And Turbo is a huge difference. Just like that Ulmer red spring he had me try. Stiff as heck. Could barely change the belt and I never got it to work well for me. Gave it to BoostedNytro and he is still running it on his sled today. Difference is alot more hp. Remember the #1 rule though. Always tune clutching as much as possible with the primary.
 
this is what i am thinking the new orange spring is to much for n/a works well on ice with good hook up get in snow spins and hits rev limit was wundering if anyone else had this happen with big venom kit never got original spring went right to new spring running original helix
