It doesn't sound good - I have one of those bikes - the lights should not come on for the exhaust - only if the engine stops or if you have low oil pressure. First of all look at the plugs - are they white? are they wet with oil? are they covered in black soot? When you drain the oil out feel (carefully) for sharp pieces of metal. You should join the VROC (google it) it is the riders club and has a forum on it where the owners of that type of bike will help you out with all problems - good luck.

None - did you mean constellations?
