I just picked up one just to part out, but now Im thinking of saving her. I have no real attachment to this particular model but the condition this bike is in is having me reconsider. Its spraybombed and looks like hell but a lot of the parts are in very nice shape! Not a ding on the pipe, swingarm without rash, overall not bad at all! Its not like i need another project but if I see some inspiration here......

I'm thinking an 84 rm125 rear wheel will fit too
If you part yours out let me know
I took these a few years ago, still in same condition, b4 everyone roast me, I know the tank graphics are for a 1980, they came on bike when I bought it, & they are not bubbling! I drain tank & carb when not being used! notice the Honda Cr style chain guide, this was also put on by previous owner, but works good and are readily available on ebay for next to nothing. I have not even 2.0 hrs on meter since complete rebuild...rebuilt crank, transmission, all bearings & seals, first overbore, wiseco, boyesen reeds.. fox air's rebuilt by Thor, the fox shox expert. Sometimes I just stare at it in my garage! I love this era of bikes..

You gave me some things to think about.
I do have a few parts left from the first one I parted out.
My 79 with 80 plastic. It has 82 forks and wheels. Answer silencer, everything rebuilt, I had a new one in 79. My brothers 79 YZ 250 would smoke it in a drag race but on the track they were equal. I went with Works shocks so I wouldn't have to adjust them. I had Fox Airshox back in the day and the Works are as good.
While the KX and CR of this year are popular for restore, I really dont come across many RM's, why is that? Back in the day there were enough on the local tracks and had attention in the magazines, the factory team had some big names too.
I will have to clean my rm up and really see what Ive got then go from there. I realize there is more value in parts then as a whole. It should be cheap to fix up as a display bike....not so much as a runner! A DC plastics kit is just over 200, and a seatcover around $50..? The hard parts will be the hurdle.
thanks
Way better than a 78-79-80 Honda's stock junk
Great looking bikes!
Does the 80 rear fender bolt straight on to the 79 frame?
First problem is no spark. Is there a common part on this bike that fails, in the electrical system? it could be something simple, I have not check it over yet.

Those bikes could be made to scream. Here's one (#666 behind #14 Mary Tripes) getting a 4th maybe 5th place start against the cream of the crop at the '79 AMA 250 National at Saddleback. The start hill before they swung left down Banzai was a true test of horsepower.
The front fender is in decent shape but will take a lot of love to bring it back, Id rather put that time into the tank, which might have bed liner on it! Oven cleaner wont touch it! Its on thick and hard.
As for the electrics, Ill just ohm each component and check with suzook for specs. I pulled the stator cover off and it looks brand new inside.
For the silencer I might just make a new front piece for it and make it a removable type, the cannister itself is also decent (no dents/scrapes)
Ya Bigal, it looks like hell but remove the cosmetics and a LOT of the parts are in real nice shape.
I think I have 2-3 original bore cylinders if you get in a bind.
I used DC plastics on my 76 RM250 racer, I liked them and thought they were a great deal. Not museum quality but great if you're gonna ride it.
I'd try some gel type paint stripper for the tank. No sissy enviro citrus stuff
Edit; The bike has bridgestone M19 and M18's on it, are those original??!!
Lookin back.. the 2 areas I didn't touch was the bore size and we left the stock ignition on it.
After reading the rules it was legal to go 80 thousanths over. making it a 265 . I would also try advancing the timing a little to put some snap into it. The power was just "soft feeling". Suzuki did upgrade the tranny gears and the 1980 model RM250T stuff is the replacement gears of choice. The original 79 tranny part numbers were changed to the 80 part number. But for porting advice, lower the floor of the intake 3 mm's and do not open up the boost transfers at the bottom of the cylinder. If I knew how to degree cylinders, cut squish bands, etc in the 70's we would have had works engine's. As it was we only kept notes on how far we moved existing ports .
The 79's didn't feel faster but they had a distinct advantage in the handling department , after I rode one on the track I knew then, I was severly handicapped riding my 78 RM250 warhorse.
I know that the trans gears were.
I think the smaller tank from the 125 would look good on that bike
