I think most of you know I'm the guy that buys bikes where the owners have no idea how to ride, let alone wrench, then fix and sell them. I picked up this 98 RM125 yesterday. (The kid thought it was a 91) He said "It ran like a bat out of hell, then made a weird noise and quit." I asked him what he did next, and he told me he towed it behind his truck. Paid him $300 and tore it apart. Check out the piston.

Squeak. So basically a 98 RM125 for what? $500
Very nice.

interesting. i never rode a 125 but had no idea they were using o-ringed cylinder/head

Yeah, that's not gonna buff out.

Did he forget to premix the oil or something? Damn...

He said he mixed it 50:1. He said he never rode a 2 stroke before, I think he started it and immediately pinned it through the gears. He told me he "rode the shit out of it and it just died".

good score man!! ya.. they always run great right before they die. 50:1 is livin on the edge a bit eh? i rode a 125 one time, it was actually kinda fun because of its lack of real power, i could ride it better than the bigger bikes because i kinda man handled it.

I used to run 80:1 in a 125 I rode the snot out of... I think he may have mixed it wrong, or like you said, pinned it cold.

whoa.. are 125's less oil needy than 500's?

125's are suppose to be 32:1. The higher reving need more mix.

250's 40:1

500's 50:1 per Maxima 2001

Although I have run 100:1 in 250's for a long time. Mostly hillclimbs and sand drags on the 3 wheeler and some in the 94 CR250.

Its mostly in the jetting that causes melt downs.

interesting! thanks iggy. i run 32:1 just because im phsyco paranoid of squeeking a motor again.. even if the oil wasnt the problem the first time..im like a paranoid pot head with that mix ratio to tell you the truth i dont even know what jets are in my carb, its run so good that i didnt care to mess with it.

Just got it back together tonight, I'm $500 into it now and it will be up on C/L for $1300 in the morning.

Good thinking...

keep the new owners number handy. good chance he will be a total retard and melt the topend again- then buy it back for $500

I love these stories. A friend of mine just scored a '96 CR250 for $200 "with a siezed motor". He brought it home, put in a new spark plug, and some fresh premix, and the bike fired right up and ran strong. He spent some $$$ on new UFO plastic and sold it two weeks later (he was going to keep it, then decided to sell it and get a newer bike) on C/L for $1400

I have done this with Vintage bikes for a few years. It's almost as fun "refreshing" them (I wouldn't call it "restoring", that's when you make them Museum-Grade), as it is riding them. And the profit helps too.

I just picked up a 96 Katana for $250 last night, cleaned the 3 year old gas out of the carbs, fresh fluids tonight and I was riding it around the neighborhood.

Funny after seeing only bigass CR500 & F7 pistons for the last year that piston looks kinda like a sewing thimble
