so... i blew my engine, ang got lucky finding a low milage, same year engine for a resonable price. got mine out, got new one in, reconected everything (cheked kev's guide, all done proper), and it just turns over and doesn't start. has spark, fuel pump's working. now, since 2 days ago (and me bickering around it, trying this and that) i have a new problem added. headlight stopped working (only works in diagnostic mode, and with flash button) and horn is a bit shy... you need to keep it pressed for 3sec to start it. diagnostic reports no problems (exept for battery voltage sometimes dropping to 0.0, but since it cranks, i don't suppose it's a problem). i'm out of ideas (and so is my father, who is mehanic with his on workshop). tried going to shop with it, but it only got all the workers scratching head around the bike. any help guys? btw, bike is xt660x from 2005.
