hi i previously posted a thread on my bike which was running sick, fixed the air filter it was over oiled, and the bike shop sold me the wrong one. so i sorted out that, and it still wont start. pulled out spark plug and held it against motor and there is no spark, i checked the fuses and there fine, can anyone help, ive had this bike a month and im severly stuck.

I must of missed it, but what type of bike is it.

I had the Coil go out on my 04' WR, it was just a bit out of specs but that turned out to be the problem.

Spark is totally independant of the battery. Check the coil, CDI and trigger coil - in that order. Good luck. Oh... first rule out loose/bad connections.
