Track not moving until 4k RPM - Is this Right?

[niko]

Ok so I've put a aftermarket exhaust on the apex and airbox and now the thing doesn't start moving the track until approx 4000rpm is this normal?
Do I need heavier weights in the clutch?

Stock engagement should be about 3,500 RPM. The addition of exhaust should not affect engagement, however, it would usually be recommended to adjust your clutching when you change the exhaust in order to get the sled running in the exhausts target RPM range. Unless of course you have an exahust that is designed to sych up with your stock clutching. Are your clutches totally bone stock?

4k on the tach is about 3500 rpm at the clutch.Your changes that you made have zero affect on engagement but may raise full speed rpm,s.

My I threw a green/white/green yamaha spring in my attak clutching and it does not engage until 5000 or 5100.

I have to do something different for next season but it really ran good but chewed up a brand new belt. Should I just go with a new clutch kit? Any suggestions?

A g-w-g will change engagement & top rpm,s by a lot.
You changed the primary spring to a g-w-g beacuse?????

I was knocking the rev limiter pretty good at 11,400 rpms. Added the spring trying to slow top rpms down. It did slow to about 11,000 but raised my engagement to 4800 - 5100. Still hit the rev limiter about 1 chirp so looking for another solution.

I bought this sled and it has a wierd clutch set up. I think it has a speed sheeve as well.

I'm not sure if they are stock weights as I bought it second hand. From what I can see its has 2 rivets in each weight.
So a extra rivet in the middle hole will lower the peak rpm's at top speed??

 

[Turk]

Adding tip weightg will lower peak rpm,s but also hurt backshift in deep snow. You gotta test & tune for your conditions & elevation as sled will have different rpm,s at even a 2k elevation difference.

4000 is a little too high if you have stock maverick track. Sled wont get traction and you will be spinning too much. Its not fun when going slow, clutch engage and disengage more at low speed.

Other than that, its not that bad, between 3500 and 4500 , its fine. Depend on how you like it.

I do have a stock track, funny thing is I'm sure the clutch ingaged at 3500 just before I changed the exhaust over???
