PROJECT: 1986 RM250

[Stusmoke]

Just started reading this thread now... A welded ignition to crank? Thats upsetting. Heartbreaking in fact, that I belong to a race that could be so stupid.

You know it, that was only the beginning on this bike. My personal favorite was the layers of rattle can paint...the black plastic airbox was painted safetly orange, then black again over that  " title="Roll Eyes" class="smiley">

It took several applications of paint remover to get to the bottom of that problem. Thankfully the airbox was pretty decently protected under all that paint.

Funny stuff, some people have no appreciation for things mechanical

WOW!  You did a TERRIFIC job!

Congratulations on your abilities.

Hey Moto Dave, Love your bike, I am starting a similar one. The little brother to yours 1986 rm125 that I have began building up. I was hoping to get some of the yellow fork guards that you did on your bike, where did you get them? are they just yellow background decals? also the carbon fiber frame sliders are awesome as well!

[MotoDave721]

Yup, just yellow background decal for the fork guards, I have been looking out for the real plastic version and will add them at some point. These projects never end!

[blbiker56]

Yeah I know, Always an on-going process. Thank you for the advice, I will grab some yellow backgrounds to use on the forks. Very impressed with your build. How does she ride?

[MotoDave721]

Well best intentions were to be riding it by now...still looking for a good CDI in my price range. As priorities go, the modern bikes are getting more attention these days (and the money), and I have two sons that ride. So I am hopeful to either trip over a new CDI somewhere like eBay, swap meets, etc...I keep looking. I should just get the PVL but $400 can buy a few sets of tires and weekends of riding!

I will be heading down to Vintage Days at Mid-Ohio with the goal of coming up with something, or another whole bike! I have to jump in to the deep end of the vintage pool, I feel like I am missing out when my bud's talk about the racing the old bikes. For now I get to walk by her in the garage as a reminder to get this project done...

Is The cdi The same for The 125 and The 250. There are a ton of 125 cdi's on eBay and a couple of 250's for around $75. I would definitely check them out cause a couple look like they are in good shape. You can also get a new coil for about $30.

[MotoDave721]

Cool, I didn't know the 125 and 250 shared a CDI, I thought the connectors (male/female) were reversed?

I have a new coil and mag, so this should be one of the final pieces. OK, now I am juiced again to get it going.

And then I picked up another project, a 1953 Cushman Eagle that is a frame up job. Because I need more projects...ugh!

I hope you didnt buy a rm125 CDi cause im not sure if they are the same. I was asking, But if you did, I guess you could flip flop the connectors between the one you have and the new one. This is just a though, but I am totally unaware if this would work.

Here is a picture of my 1986 rm125 CDI Connection.

The coming from the CDI is on the Left and comming from the stator is on the right.

The  CDI plug wiring on my 85' RM 125 & 250 are both different.

[MotoDave721]

Thanks for the pic's guys, my plug is inverted from that from the stator. I will keep looking, and hopefully be up and riding sooner rather than later.

I picked up a brand new 2002 RM250 last fall and have been spending weekends getting my moto on, what a great bike! Rare to find too, so I had to jump on the deal, so the real vintage RM250 sits and waits...
