Home YL1 YA6 CT1 RD200

 

This is the first 180 Yamaha YCS1 I built in 2002. The Exhaust port was raised 2mm and the piston skirt was cut 6mm. It had Barnett clutch plates and a couple of closer ratio gears from an RD200. I used Chevy points and made the backing plate and cam. It used total loss electrics. The seat is a TD1C fiberglass replica made in Oz and sold by Neil Collins. He also deals in many NOS and used Yamaha parts. The fiberglass gas tank was given to me and when I couldn't stop the leaks, I made an aluminum tank to go under the fiberglass shell.

 

The frame is stock except for the footpeg mounts and even has the stock rubber swingarm bushings. I'm using stock CS3 forks with spring spacers and 30w oil. The rear dampers are an old set of Boge that I had in my spare parts. I'm happy with the handling and the power is good. It weighs about 200lbs.

I won the USCRA 200GP championship on it in 2005

 

 

This is how it looked in 2007. It has a PVL ignition and I made a dry clutch. I've made a few sets of chambers but the first set seems to work best. The crank had been in it for 4 years without a failure. This year a rod bearing got loose and I replaced the crank. It now has both chambers on the right side. I also raised the bike a bit to get more ground clearance. The clutch drive needs to be modified as it is getting worn.

My son rode it to the USCRA 200GP championship in 2007, 2008 and 2009

I traded this in 2010 for the 200 Honda John Branson Built and used to beat us in 2006
