Over the past 6 months, I've had opportunties to share my experiences rebuilding the SR500 cafe racer that some will have seen and most will have heard. In that time I've: - rebuilt a carb by the side of the road, - blown out a tyre at freeway speed (and found the inner tube wrapped around the rear hub), - fired the exhaust baffles out of the muffler - split an external oil line, dropping all the oil onto my leg and the rear wheel as I took a sweeper off the freeway, - had a regulator disconnect itself, sending an unregulated 35V to all my 12V globes (flash! - ride home from Flipper's at 2am with no lights) and sundry other minor annoyances. Today i strolled out to start the bike (after a few days without using it) and kicked it over to TDC (standard SR500 procedure) only to have it rotate past TDC under its own momentum. Hmm...not good. Try again - same thing. Out with the plug, kick it over with a finger in the hole and - no compression! So its either a sticky valve or a holed piston. So the motor is out, rocker cover off and over the next few days I'll explore the top end. If it looks a bit shagged, I might put in the 540cc kit and port & polish. The long and short of this is that I'm aware that many newer riders won't have seen the inside of a motor, so, if you want to have a look at what's going on inside yours, PM me. I promised to host a spanner day ages ago, but it hasn't happened so for those curious about all the whizzy bits inside your motor, feel free to come and have a squizz.
