Just want to report back on this matter. Had the exact same symptoms as Grumpleton. Took my bike to RAD for valve clearance and bike starts with the push of a button. My bike still has the SM17 starter so the starter is not the real issue nor is it the battery
As the heading indicates. Looking for a Triumph 800 XCX complete front rim. Wifes front rim has developed a small hairline crack. It is currently functional but would need to replace in due course
