Hello, I am needing some advice on the clutching. My whole sled is stock but I was looking at an adjustment on my sec. clutch. It looks like this thing has a adjustment on the front side of the pulley by the hole where the belt remover tool gets screwed in? Is this something I can adjust, and what does it do?
I run about 7800 rpm but wanted to get that to 8. I adjsuted the primary but that didn't seem to raise the rpm, any thoughts?

Thanks Joe

Welcome to the site Joe!

The adjustment on the secondary is to adjust belt deflection. If you want to raise your top RPM's, then you need to move the clickers on the primary clutch to the next highest number. If it is still set at stock settings, it will currently be set on 3. If you move that to setting 4, you should be right at 8K.

Thanks Keith, that is what I thought with the primary clickers. But what do you mean by belt deflection?
Thanks Joe

You lay a long straight edge (long enough to reach the centerlines of both clutches) on top of the belt. You then press down on the belt in between the clutches with 25# of force. At that point, you should have about 1 1/4" of deflection. You adjust the belt deflection by loosening the 3 bolts on the outside of the secondary clutch then turning the adjuster ring.

I will check it out.
Thanks Joe

you can get great gains in the clutching on the 700.

do you know where i could find an illustrated version of what you just said about moving the clickers on the primary. i'm not very familiar with clutches yet, and i'd like to see what you're talkin about. thanks

It's in any service manual. I'll see if I can find a pic.

so there are three of these calibration screws then right? with my 03 600 HO mxz will it be set on 3?

have not had stock engine for a while but have not found that each clicker will give you a true +200rpm gain in each additional clicker. But it might in a stoch engine. Do not take the rpm readings on stock tach for trueness as can be different for every engine. try and test, best to test against a sled that doesn't change its mods while your doing yours, esp. on different temp days

There are three of them and all stock sleds come set on #3.

On a stock engine it will be pretty close to a 200 RPM increase with each click. It is very common for Doo tachs to be out of calibration, reading about 200 RPM's high. ie: if your tach reads 7800, it is really turning 7600. You can have it checked, but more often than not, it will be reading 200 RPM's high. If you are trying to squeak out every MPH you can in a certain distance, then LetsDoIt has the best system. Test against a mule sled. (one that you do no changes to so you have a baseline to judge your changes) Many times, the fastest feeling sled is not the fastest.
