neilnh Posted March 11, 2012 Report Share Posted March 11, 2012 Rev 3 with very weak spark and wont start, was running fine and its not long had the stator done so hope its not that CDI COIL maybe ??? Quote Link to comment Share on other sites More sharing options...
bmseven Posted March 11, 2012 Report Share Posted March 11, 2012 tried the obvious of another plug? Quote Link to comment Share on other sites More sharing options...
neilnh Posted March 11, 2012 Author Report Share Posted March 11, 2012 tried half a dozen plugs and a new plug cap Quote Link to comment Share on other sites More sharing options...
vicx Posted March 11, 2012 Report Share Posted March 11, 2012 Hi there. I had the exact same problem that turned out to be a faulty kill switch. We had a weak spark but as soon as we put the plug back in it wasn't strong enough and the bike was dead, same as you it had run fine when put away. I've now been caught out twice with kill switches - the other time with my fantic- but an easy and cheap thing to try before looking at the expensive beta electrics. Hope this helps Vicx :-) Quote Link to comment Share on other sites More sharing options...
neilnh Posted March 11, 2012 Author Report Share Posted March 11, 2012 Took the kill switch off and still not good spark and no start either Quote Link to comment Share on other sites More sharing options...
paul w Posted March 12, 2012 Report Share Posted March 12, 2012 only way to do this is to find someone with the same bike and swap parts. Quote Link to comment Share on other sites More sharing options...
dadof2 Posted March 12, 2012 Report Share Posted March 12, 2012 (edited) Find someone with a multimeter that measures ohms. Your stator will I think have 4 coils - three with thick wire and one with fine wire. Measure the resistance of the fine wire coil at the terminals that plug togeter at the top of the radiator. Should probable be about 250 to 300 ohms. Try measuring a good bike if you can. If resistance is infinity (open circuit) coil or a wire to it is broken. If resitance is well over 300 wire may be thinning / about to break and won't flow enough current. If resitance is much lower than 250 windings are shorting and wont generate sufficient voltage. Try bradford rewinds or west country windings - cheaper than whole new stator. Cheers Edited March 12, 2012 by Dadof2 Quote Link to comment Share on other sites More sharing options...
