I kept trying for a grey-bike ride!

Not enough interest a few years ago.
MC22's are fantastic bikes. Upul's bikes aren't great and you need to know how to and want to wrench on em. I've replaced every single thing that MXS has mentioned. Rotors & pads, bearings (all of them on the chassis and wheels), chain, sprockets, petcock, fuel filter.. first I replaced the carbs, then I cleaned the carbs out several times, fork seals, cleaned & lined the gas tank, spark plugs, throttle cables, choke cable, levers, h-brace, Mirrors.. All replaced in the years I've owned it.
In dealing with him, he did take care of my major issue after purchase. I had a 1" in diameter hole in carb #1 vacuum chamber that was epoxied over. The gas was eating the epoxy and I was getting major vacuum leaks. Upul fixed me up with a new set of carbs. They have been good but the float needles will need replacing soon (rubber nipples are getting worn.)
I remember meeting a guy who bought an NSR250R from Upul (Nuak). We met in Gravenhurst for bike night up there (Thursdays). He was pulled over on the side of the road, changing plugs. The bike would run great on the highway but the minute he pulled off the highway, plugs would foul. Needed work. I wasn't surprised and told him about my happenings with Upul and my bike. It all kindof was in-line with what I now expect of his bikes.
Ah well, I'll never sell my MC22 now. Once the motor stops running and I cannot repair it, I'm going to build it into a bar. Vroom Vroom:
