Change your clutch engagement rpm for CHEAP!

Adding shims to the primary spring on my 97 yamaha vmax 500. This puts more preload on the spring, increasing engagement rpm.
Clutch shims. These are .060, the ones that I saw were .072. Whatever... send it!

Ok perfect. I race a car with a 440 pro x in it and I was trying to find out how to adjust the clutch to launch a bit quicker. This is perfect.

[@shooter1817]

torquing is important,70 psi at first then back off and retorque to 48psi approx,makes a difference where the primary sheave engages the belt.Thanks for posting.

I'm going to shim my 340cc. Gonna make it hit hard.😮

[@neilruhl2523]

Thanks! Great video, I learned a lot!

[@TheHunter1o1]

Excellent video

Dude, I shredded a belt getting stuck in heavy wet snow. Yamanha Triple 7. But now my sleds clutch doesn't engage until 5k RPM. I'm new to sledding & learning a lot. Previous belt engaged around 4k. I think I might need a new spring or rebuild primary. Thanks for the vid tho, certainly helpful.

Wow! Thank you!

[@lasseanti6084]

Or you could buy a spring with more preload.

[@Metcalferacing_29]

so this will make the cluch engage at a lower rpm ?

[@Whitestrash]

Higher rpm.

[@Metcalferacing_29]

Hmmm ok. Does that affect the top end ? Does that affect the acceleration? I’m confused ?

[@Whitestrash]

@@Metcalferacing_29 it shouldn't effect the top speed. It just helps launch a little harder. Quicker acceleration off the line.

[@TheHunter1o1]

Do you know how to split the sheaves on this clutch?

[@Whitestrash]

I haven't done it on one of these. I have on polaris, but I'm sure they're different.

[@TheHunter1o1]

@Whitestrash thanks for the reply. Yeah, possibly because I can't seem to split it apart.

[@Whitestrash]

@@TheHunter1o1 I know on polaris you need a special tool for the spider and it takes like 250 ft lbs to break it loose.
