Crank & Piston Kit: 01 vs. 05 YZ250 differences?

Recommended Posts

I'm not in a position to write down a bunch of numbers and im sure I just seen a thread about this but can't find it.

What's the difference between a stock crank/piston kit for a 2001 250 vrs a 2005. I'm picking a 05 up in the morning for my son and of course know nothing about it and if it needs it I might as well save some money and use what I can of what I already have

Can use 01 in it but youdhave to have 01 seal,collar ,primary gear to go with it. 05 is different on right side

He's going to like it nice choice 👍 

Coming off that 97 rm 125 he'll be in hog heaven. I'm sure I'll be in a immediate race first time out and I won't loose, if I have to kick, grab levers etc I will win the first battle🤘🤘🤘🤣😂

99-19 pistons are all interchangeable. Cranks are 99-00, 01-02, 03-19. But you can use 01-02 in all up to 19 if you buy the flywheel, and the small splined collar for 01-02, and/or flywheel 99-01. 02 has a one of a kind flywheel.

Actually it is only the flywheel, and the spline collar under the primary stack. Everything else would work on 01-19. 99-00 cranks will need the big collar they came with for the primary to stack properly.

 I'm down with some flywheel weight. If I could I'd add 10 lbs to mine. Make it like my old tiller, one pull off the string and it turns over like 10 times 🤗😂

Maybe.  Deff if i start racing more get in shape again.  Then id have to go back to A class. Now can just show up and be competitive in B with armpump and tounge dragging lol . That race i did was on old national track long and rough. 5 laps was to much for me now days pushing it. Next season hopefully get back serious
