Can some one tell me what a safe top RPM for a 76 John Deere 440 Kioritz should be?
I have been riding the Deere Ski out in back, the clutch kicks in around 4000-4200 rpm
and in no time it is over 7000 and I run out of property and have to shut it down.
What would be a top rpm for this motor?
I see the Liquidator runs 7-8,000

At Low alt. sea level to 6000 ft. Clutch engagement should be minimum of ( Deere spec ) 3400-3600 RPM, you real good where you at.. Max Operating RPM/Governed Speed is 7250-7750 RPM..
Dator is 8000-8500 RPM

Thanks Grumpy. I'll have to get it out on the trail and see what it does. For a secondary I am running one from a Ski Doo 500.

I would guess the doo secondary has a stiffer spring and different angle in the helix. It might over rev the motor not letting it shift out all the way. Also the diameter might be different.

Took it out last weekend and got to opener up. 
Runs great still climbing by the time I had to shut it down, corner.
It's not registered so until then it is a great running custom.
