Looking for the lighter 650-701 crankshaft to rebuild. I believe they are PN 6R7-11400-00-00.

Thanks for looking.

Yes, I am. That would be perfect. I’d like to get one.

I think you are asking for the older 650 crank that was hollow inside the rear coupler threaded area, and also had different webs.
Guys responding might not be aware of the difference in those rare cranks and that is what you are asking for, not just a std 650/701/760 crank core but an early 650 rare one.

Do you know what years those cranks were used?

Not offhand, can see if we have any notes about them here.

All the 650s that I have seen thru 1993 had a bored end and the slightly thinner webbing. These cranks may have used on later 650s but they were vanishing quickly after 1993. I remember it was common to see rebuilt cranks with both 650 and 701 webs. The rebuilders didn’t care. FYI we had a rider cut the webs out completely and use it in a 760. It lasted several years until a piston cracked.

Yes, this is exactly what I am asking for. Thanks for making this more clear.

I have one, plus everything else you need.
And I'm in Havasu.

I’ve only seen them on a few early 1990 skis. Local salvage place has 50+ 650’s and all are 6M6 webs and solid rear. These skis are 1990-1993.

Same as the 760 crank with holes in rod versus slot. Just a few from early 96’.

Back in the superjet (97-02) hey day guys would get DQ’d for these cranks.

The ruling was the 650 is a different model ski thus not allowed. Back dating was only allowed within same model

Also the trick was Suzuki or Honda hollow pins and Suzuki sled bearings. (Arctic Cat)


note today you can use it in lites. It was questioned to IJSBA and it wasnt even understood! Guys run these cranks, 650 heads, nozzles, and other parts.

There is such a small difference in strength and weight, does it really matter?

Great point! Especially back then with Dry pipes, 48’s, msd total loss, 58mm exhaust ports ,and 195-205 psi. It was a handleful

So, were these cranks found in the oddball 650lx machines?

Call me. It’s Chris

Still searching…

All four of mine came from 1992-1993 Superjets.

What difference in performance are you talking here? Just curious what it can do VS a regular old rebuild.
