But would the parts from the 490 fit on my 250? that's the question. I am leary.

No ideas on this one?

Had someone mention to me to try trading the drive gear and clutch assembly for one from a 490. He said going from spline gear to straight gear would be noisier but would increase HP. Anyone tried this? Would it even fit?

What do you guys do for getting the motor back to black. DX? Paint?

I see your bike has an aluminum kickstart. What year did you have to get to make it fit?

you need a wrench to hold the dampner rod( use 15/16 to 1 inch nut welded to a 3/8 socket, i do not remember which size) use a long extension to fit into hex on top of rod
heat allen with a map torch then use a air impact to spin off
make sure its hot

OK May have an issue. Disassembling forks. Had two different kinds of oil (one blue?), so I know they have had some attention, just not in the last 20 years. My drain plugs at the bottom are just spinning on both. Most likely stripped?!? What do I do? ... more »

Need to go get a socket for the nut holding on the clutch basket. Anyone know what size it is? The biggest I have is a 22mm and it is too small.
