Clutching Wah Wahs problem

[robandrus]

So I can't get my 04 800 to hold 8000 rpms, or even 7800 for that matter. It just bounces around up there. I read up on what DJ calls the Wah Wahs. Accordingly I've kept adding weight to my primary. Here is my setup, 160/290 spring, 415 ramps. Just replaced the secondary spring, and buttons. I'm not really sure how much weight I now have in my primary, I have the hollow pins plus one big weight and one small one.

This week I added the extra smaller weight, started at 3 and tried it out, only hit 74- 7500. I moved the clicker up and it went to 7700 but still bouncing around.

Also I was doing some hill climbing and near the top of long pulls, (when it got really steep) the sled bogged on me. (Consistently in the same steepness over 4 or 5 climbs).

Anyway, don't know if the two are related but can you help me out? Is bogging ever a sign of too much weight in the primary? Also I know that some of the internals of the clutch are worn? rollers have some visible grooves, missing some of the rubber washers around the buttons, some wear is visible in the slots where the primary buttons slide.

Help?

May or may not be clutching related....Aftermarket pipe or head? Jetting....too lean? Gearing too low? Have seen this from several sources.
Would be a good idea to make sure all the worn clutch components are replaced to eliminate that variable.

Jetting is rich if anything. Snow is hardpack, gearing has been the same for years, this is the first time its ever bogged on me.

Did you change ANYTHING when this started?

Earlier this winter I had a piston burn up. I replaced the pistons and put in the 160/290 spring.

Like I said this is the first time its bogged. The rpm problem started around the rebuild.

Are you losing coolant?? Look for evidence of burning coolant on the plugs....yellowish color?

When the piston burnt down did you check the crank seals?
It sounds much like a seal leak to me.
