soo i have a 99 r1 and it wont start at the moment. the starter is turning but the motor in not cranking over. dont know what is wrong. any help would be apericated.

 

was it stood for a while without being started? first thing i'd do is take out a sparkplug and inspect it, i thnk they recommend changing em if they're caked in soot, but a rub of a wire brush might help em fire the bike up (i recently gave a set out of a dead 250 the old sandpaper treatment too but i prolly shouldnt have). if they're wet also it might mean ur givin it too much throttle tryin to start it, you'd wanna take em all out and brush/dry em. check for a spark by py plugging into the HT lead and holding the plug against the engine block.
the plugs are supposed to be gapped according to the handbook specs, check ur bike toolkit for a feeler gauge (sometimes provided)
