The Dalton black / teal spring

And running the stock rollers

Purple hurricane spring st 6-1 - tried a couple other springs but liked this one the best with my set up

Could prb use a gram in the tip with a o ring depending on conditions but it works for me 90% of the time with out Rev limiter .. I'm only running the 129 skid no picks and a 1.5 ripsaw.. If I pin it from a stand still it will bang the limiter for a split second on hard pack

I have mine set at 0-1 seems to work well. Have you tried it at 0-1.

I'm running stock primary spring and rollers with one tungsten in the heal and purple secondary and it runs about 8900 under full throttle after I checked it again with a new belt. Old belt would bang the limiter on take off ,it had over 5000 km on it!
