2016 SR Viper LTX-DX Turbo
Hopefully everyone is out riding and I can get some answers Monday!

I have the 58g thunder products kit installed on a MPI equipped viper (2016 LTX) with about 1100 miles on it. I had been running clutching from the shop I bought the sled at but it felt heavy and I saw a deal on a used big venom kit.

I put the heavy hitters in with the full set screw, and just a steel 3/8 to feel how much weight to add figuring I'd bounce off the limiter and the sled will only hit 8300 rpm and does 90...

Do I keep taking weight out? Something doesn't feel right. The secondary is set up with the kit spring in the 6-1 slots.

Any tips or thoughts on what's up? Snow was loose but if anything I think that would put engine speed up?

Thanks all for any insight. Ive done weight swaps and spring swaps before but it's been a minute or 2 and I'm confident I'm doing something silly and I'd like to avoid banging my head into the wall!

Which primary and secondary spring are you running, also where is the 3/8 bolt, tip or mid?

Blue silver blue on the primary (stock I think) and the BV secondary spring. Not sure of the specs .

I had a 3/8 bolt in the tip and mid.

I didn't pull them out to see what no weight would do but I can. Shagman made some recommendations and this is less weight than that even. Feels like I'm missing something .

Thanks!
 
Looks like i'll be trying some new springs in the primary and secondary and see where that gets me.

Has anyone ever had a throttle position issue where WOT isn't WOT? This is gonna keep me up at night :P
