Sadly, this is one of the only pictures I have left of my old moto days. Here's my 79' 125 with a 80' rear fender and a PP front fender. I'd work all Summer to raise enough money to buy a new bike in the fall, and I'd race it for two seasons. Yes, it was a chore keeping a late-70's 125 running for two years.
My on my 79 250 at Gatorback.
Once I tear it down I will be looking for frame cracks throughout. I suspect that a lot of the frame cracks were caused by excessive engine vibes/too small mounting bolts.
Going to try and fire it up today. Holy shit is it a bitch to get the airbox + carb boots mounted, not much wiggle room.
Edit: It runs!
I wonder if you can purchase just a Pro Form silencer?

Someone told me the maico 250 guys would run a 125 size tire back in the day?
I also owned 2 of the Maicos you were referring to in your next post. The Maico powerband was not explosive but provided the feel of more torque . One I kept fairly stock, practice bike, the other had the Crotch Rocket Factory Pipe among other mods. It was also tuned by Lee Barkley of Kimbrells Maico out of Dallas. (Race Bike). The Maico's power enabled me to ride a gear taller thru a lot of turns and carry more speed. Hope this helps.
If the guys using the smaller tire were on a tight track I could see the need for a smaller tire to help light up the power delivery. As with most Maicos it was pure hell trying to pull in the clutch lever to fan the clutch like we became accustommed to doing on the Jap bikes. And yes i would love to have those two Maicos back , in the pristine condition they were in.
So did we run 460 x 18's on the hopped up 125 Nat'l bikes back then? Or just the 425 /410 x 18's? The Dunlop K-190's maybe, I can't remember.
I can say that the 17" rear wheel assy's that were made available were , in hind site, not the way to go.
Does anybody remember if the Metzler rear tires were 4.50 x 18's or 5.10 x 18's.
I found yet another snippet on this issue. In another mxa mag in the "dirt" section, they mention,
"It turns out that on the first shipment of RMs into America the Japanese forgot to insert a steel sleeve into the motor mount holes".
Im not sure this is true, on the microfiche, I see no sleeves on the motor mounts except on the front there is a case locator pin....
