One Stop Performance Dark Energy Adjustable Yamaha SR Viper Clutch Weights

[onestopjim]

NEW FOR THE 2015 SEASON- Dark Energy Adjustable Clutch Weights. Yamaha SR Viper Clutch Weight Kit.
One Stop Performance clutch weight kit improves acceleration & performance.They are custom adjustable to suit different power ranges. For the average trail rider with stock power & modified naturally aspirated power and low boost turbo power. Weights are harden & black oxidized for years of rust free worry free performance. Weights come with magnetic inserts (to finally tune your weight adjustment for your needs)

Our harden black oxidized weights have milled out holes that the magnetic inserts fit into the weights to get the best weight for your riding style.

Engineered specifically for Yamaha SR Viper

These weights are not like stock weights nor our competitors weights who use universal weights that fit multiple sleds. All our weights have 2 years of intense trail, lake drags, grass drag & asphalt drags racing testing & tunning to make these weights our best secret weapon. Along with all of our other clutching products you get a extremely long belt life. In additon to our proven extensive extravagant testing we found that this kit provides Cooler running clutches and a much better belt grip with emphasis on much better belt life.

Holy cow! Nice! I think you all know how I just love the magnet style weights. Is the ONLY weight that tip weight can be changed without removing weight. These look even easier to change and profile looks very familiar to me. Very flat. I am in. One set sold!

Interesting. I wonder how the profile compares to the Yamaha 8FP weights?

Adjustable 8FP weights.....very cool.

this are not a copy of a yamaha weight our PROFILE on the weight is different than any one else we spent lots of time testing to get the perfect profile to get the best belt bite and acceleration.. these will allow you to run MORE HP to the ground.
they are adjustable to add more power.

That was a compliment from all these guys! I am sure it's not the same as 8fp. But main reason I never did the 8fp thing is they are terrible for adjusting. Liked Ulmers for adjusting and loved the Magnaforces for adjusting. Will be nice to have closer profile to 8fp AND the awesome adjustability of the magnets. Nothing comes even close to how easy and fast it is to adjust with magnets. I can't wait to try this setup. I see they are headed here already. Thank You!

Didn't mean to offend as everybody knows I like the flat profile weight. But I am confused, I was talking about the weights in the pic below that are very much 8fp profile and even have a GWG spring. Maybe we are talking about two different sets? The one in the pic below interests me the curve profile not so much for my use. I may buy a set of the ones below in fact.

Are these designed to add wieght/magnets to both sides?

Throw them in and go find a football field and let us know if they wake the beast up a little more

Cannon the new Vikings field is almost done we could do some testing there

Maybe take it back to that gravel road I took that 106mph run on! They will work and tuning these is gravy. FUN!

Question for OSP. Is it safe to run 3 magnets a hole or just two? Can you supply the shorter magnets like Magnaforce has? They are identical dia and fit 3 in each OSP hole. Nice to have combo of magnet sizes!
