So could you tell any belt slipping what about how it holds back does it still

[@weekendsxsguys5599]

No i haven't had any issues. but if i was heading to the Hatfield in McCoys i would put it back in for that trip. but those are slow with lots of climbing

Update on how you like or dislike with spring out?

[@weekendsxsguys5599]

in Michigan i like it without the belt. But we are pretty flat, most of the trails are 25-40 and the noise in the cabin is very noticeable for the little bit of power loss. when we head to West Virginia we put the spring back in.

[@gordonsillars]

Wow! About 1000 RPM drop. Any negative side?

[@weekendsxsguys5599]

the mid range probably lost about 8-10 hp the bottom end felt the same. if i was rock climbing in WV or Tennessee id probably put it in. but me being in MI we are a flat state

if you lower the rpms the power is gonna be lower no matter how u lowered it..if you added weight to the weights and left the primary spring in it would still be lower on power from the rpm loss...it was a free mod to lower rpms and get better belt life for the ones that wanted less noise and heat and its easier on the weights wearing because they have less force to push@@weekendsxsguys5599
