David’s story: “Back in 1982, my late best friend and Yamaha TT500 riding buddy had an engine built by Hi-Per-Kinetics in Paramount, California, for his 1977 Yamaha TT500. He was going to replace his somewhat hopped-up 540cc engine, but never got around to it. Another friend bought the engine and put it in his stock SR500. He rode it until he got tired of tickets or something and put it in his storage just outside Santa Paula, California, in a converted milking barn. There it sat for over 25 years, until I found out about it.

“After getting the SR500, I squirted some oil down the spark plug  hole, cleaned the carburetor and changed the oil and filter. It started after about 14 kicks.

“I think it’s running 11.5:1 compression. I’ve got it down to one or two kicks to start now. It’s quite the handful to ride putting 43 horsepower to the pavement.
