Need help M7 clutching guru's!!

More weight should make it feel a bit more torquee and will lower your engagement and peak RPM assuming both weights have the same profile.

 

[wreckednak]

So what about getting the same results with a stock M7 at lower elevation, 0-4000'.

 

[Speeedracer]

I thought those motors were supposed to run in the 7400 to 7500 range.......no?????????????

 

[irydcat]

Everybody that i know that has m7 run between 7800 to 8100 so i think 7500 is a little low.

 

[MTm7]

yeah 7800 to 7900 with stock setup. usually 8100 with slp twins or porting with a good single.

Aaron,
When you reinstall that clutch cover, make sure you line the 2 dimples up so so it stays balanced.

Ditto! I was thinking about that after I posted my reply to Aaron. Thanks dmkhnr

If your leaving 1/2 inch on the primary check for spring bind. I am telling you all that if you run a primary spring that is not AC it will hang up in the spider. IF the paint is warn off the primary spring chances are it is binding up.

To test this run the sled up to speed let off the flipper then nail it again. IF you mph better your cramming the spring in to the spider cup. We have bee trimming the cup out to the braces and there is nothing holding the stock clutching back at all.

It can be cut on the sled with a porting template. We have cut a few just on a lath with the spider still in the clutch. Ahh ya that is a 036 at full shift.

Don.

Rich, and anyone else looking for a arctic cat gold primary spring. It's rated at 75-285 lbs. If you cant find one, look at slp's springs. they make some black/pink and others that might work well also.
