Rpms - Peak rpms get lower as day goes on (summit)
Question) (04 800 rev, 9000', dynamo Joe clutch kit) I have noticed (only in powder) as the day progresses that my peak RPM's get lower and lower and lower, I have dropped almost ALL pin weight (down to the last 1/8" weight in each pin) while I have it on clicker (5,6) this setup is great in the hard pack, but in powder while initially is great, but as the day goes on gets progressively lower and lower peak RPM???? what to do?

Answer)A clutch kit is what it is and the calibration of it does not change over the day unless the primary or secondary springs are sagged out.
An engine will change it's personality over the day due to ring "fatigue failure"...even over a 10 second run, an engine will lose it's hot compression values - RKT has mentioned this dozens of times on dootalk or snowest.

Rpms - Fluctuating up and down, clutch fitness?
Usually system high temperature is from fluctuating rpms or worn bushings or high rpms or low rpms.

It would be an investment to know what kind of shape your secondary is in.
Can you get the diameter of the big bushing checked?
The bushing is at the wear limit at 89.15 millimeters or 3.510 inches.

On the primary clutch, visually inspect the coating of the 2 bushings for wear. Using a bore gauge, measure the inner diameter of the bushings – Measure point must be 5mm (1.4”) from the bushing edge.
*Spring Cover bushing – Replace bushing or cover if the inner diameter is a 30.40mm(1.197 in)
*Sliding sheave bushing – Replace bushing if inner diameter is 40.30mm (1.587”)

Question)  Joe I have your 800 clutch kit in a stock engine.  I am getting an RKT Piston drop in kit and now the engine will go from 7800 to 8400 rpms.  Is there anything I can do to get your kit to work.  Right now I'm using 25g in clicker 3 with the kit primary spring.

Answer)  This is an easy change to do and the piston drop in is an excellent marriage to the clutch kit.  You have a 230/350 primary spring and using 25g in clicker 3.  All you have to do is change out the primary spring to a 230/380, reduce pinweight to 23g and change clicker up to 4.  The engine will quickly accelerate to 8400 and hang on.

Question)  Joe I have your 800 clutch kit with a stock engine.  I am getting an RKT Piston drop in kit and now the engine will go from 7950 to 8400 rpms.  Is there anything I can do to get your kit to work.  Right now I'm using 17g in clicker 3 with the kit spring.

Answer)  This is an easy change to do and the piston drop in is an excellent marriage to the clutch kit.  You have a 160/320 primary spring and using 17g in clicker 3.  All you have to do is change out the primary spring to a 160/350, maintain the 17g and go up to clicker 4.  The engine will quickly accelerate to 8400 and hang on.
