My Yamaha CT2 Road Racer |
At the starting line at NHIS |
The frame is stock and the front end is from an RD200. I made a dry clutch and machined a basket to fit TZ125 plates. I machined 3 pounds off the front disc. It still has steel rims and tires that are too big and weighs about 185 lbs. |
I machined the head out of a block of aluminum after failing to find a MX center plug head. I made a new clutch basket to fit TZ125 dry plates. The drive for the dry clutch needs some more development. I made 2 pipes but haven't checked them on the dyno. |
I cut away a set of cases to help while modifying a 6 speed from a later model MX175. Had to grind some of the gears a little thinner. Took a while but it works. |
Next project, after modifying the dry clutch, will be a new frame like my other bikes. That may get the weight down close to 150 lbs.
|
I finally made the the frame but decided to use
it with an AT2 125 motor. It's on the AT2 page.
|
|
Then I decided to go back to a 175 so I sent the barrel out to Scott Clough in California to modify. It now is faster than my RD200 and the new frame handles well. I also made a new pipe and will be installing the 6 speed transmission. | |
I had to move the indexing hole over 4mm |
I shortened the cam about 2mm and make some sleeves for the fork shafts.
|
This cap stops any end play of the fork cam. |
I pressed on a sleeve for the neutral plunger.
|
Now the revs only drop 2000 from first to second and only 850 between 5th and 6th gear. The motor never drops below 8000. |
My son races it in Vintage Singles and it's faster than the 500cc singles in that class. |
