Crank failure modes

[Gasser Nate]

I have never liked those roller bearings, pain in the ass to get off the crank and from my testing don?t last as long as ball bearings. I always replace them with ball bearings when I get the chance even though logic says the rollers should last longer. If it has those sealed type mains I have seen them suck in a gut full of water through their seals and then rust away because the water can’t evaporate out. And that is pretty good hours out of a racer!
But after that bit of info I am wondering where else water made it too?

When you replace the roller with a ball bearing, do you use the same part number as the clutch side or is it a different bearing?

Bike has been completely disassembled since then. We flipped it over in the creek and took the plug out, cranking the engine over and over to get the water out. Squeezed the water out of the air filter, got back to camp, changed the gearbox oil and rode for three more days (about 7 hours total) before the crank finally gave up the ghost. Tough as nails!

Well the right crank end nut is putting up a fight. Even once I read the manual and started turning it the right way. Goodly amount of heat. My rattle gun isn't the best so I may take the bike to a mates.

When everything else fails, read the directions
(I did the same thing, except mine came loose right away)

Zman: On the '01 200, both crank bearings are the same.

Put up a fight but finally off with better rattle gun and bigger bar through small end so it didn't bounce so much.

Then it was the swingarm bolts turn. Slowly slowly, biggy hammer.

He did lend me a crankcase splitter too. Flash.
