Me and my HS buddy were corner-marshaling our first race, WERA weekend, Gateway, 1986. 125's, tons of them, sprint race.....one goes down......my teenager brain goes into full panic on the headset/radio.....crash! crash! crash! LOL Anyways, went out and picked the bike up and helped the kid get back to pits. Little black kid, nice kid. I cant think of his name offhand, but he became a pro racer years later. Robbie Peterson/Patterson, maybe.....? steve(i) patterson?
Nope, not at all actually... This kid crashed a lap previous. I just have big clunky feet and accidentally stomped on the rear break mid corner.
Steve Patterson of Detroit. He last rode for Team Pearls when they went AMA Pro. The last time I saw him was when he was parts mgr. at Rosenau in Dearborn Mi
On a slightly unrelated note - has anyone attempted or know of anyone that has attempted to fit a fuel injection module (like Ktms TPI) on an RS125?? Figure it could take away the massive headache of swapping jets.
That would be a massive undertaking. KTM's TPI isn't throttle body based, it requires injector ports into the cylinder's transfer ports. You could use a Get TBI kit instead as the base, plus you'd need injectors, a pump, the sensor suite, an electrical system up to driving it all, and THEN you've got to come up with map and ignition curves to make it work. It's not impossible, but it's not a weekend project either. Going for the simpler approach I tried test fitting my 38mm SmartCarb on a friend's RS125 with the hope of a small bump in power plus no need to rejet for different weather conditions without having to screw with an EFI conversion. The float bowl setup is too deep unfortunately, won't fit.
I figure a small TBI system running on a small LI battery would be sufficient. I think a general mapping like a typical 4 stroke wouldnt be an issue outside dyno time. The big issue is adjustment for inlet temp and etc. . . .
Would be better off using a fully programmable system like MegaSquirt. We used to run those on turbo cars back in the days. Power for the fuel pump would likely be the biggest drain on the battery.
Cool pic, I know Peter personally, and no offense, but you should of bought those pics... Hope you got her fixed up...
If there was any use for these photos besides one online post making fun of someone, I would have bought them.
So there's a happy medium here, I have a tz125 that's I dropped a wr250 motor in,(moto 3) fast, light and what maintenance. You can beat those little motors all day long. Fuel injected starts fist bump every time.
I can no longer ride a RS125. My old knees just cramped up too much. However, I will tell you that one of the 'old timers' who showed up for a few races at my home track with an older RS125 was able to smoke all but one of the bikes in our Lightweight Superbike class. The class includes all the 400 Kawasaki/R3 Yamahas/CBR300 bikes. The race had around 15 entries.
That doesn't surprise me at all. After the comparatively crappy start on the RS due to the lower torque it'd be a matter of picking them off one or two at a time.
