I think I'll start building another bike. I know I have thrown out various combinations but I want to try this as an addition to the three race bikes I already have. At least I have the base bike or engine. I have had this 1985 Husqvarna XC500 for several years. I paid very little for it and it needs an engine rebuild. I already have an RZ350 that I run in V6LW and this pre 1990 500cc two stroke is allowed in there also. When new these Huskys were just a couple rear wheel HP down as compared to a CR500 Honda. I had a different 500 Husky back in the day and it was quite an armstretcher. First thing is to rebuild the engine and ride it to see how bad it vibrates at peak HP RPM. If that looks good, I have a complete 650 Suzuki front end I can easily put on it. Then just rig up a lower rear end height and DOT tires. Another question is, can I still kick start one of these at my age. I CAN still start my 430 Husky. In this basic state, I can take it to a track practice session or two to see if its worth continuing the project. If this all works out I would hope to go to better rear suspension and wheel along with different ergonomics and fairings. I really enjoy putting stuff together and drinking Beer while doing it!
