drained petrol tank of fuel just incase water has got in there? by a hotter plug i meant one grade higher than the spark plug you have installed, clean the spark plug cap and spray inside it with wd40 to drive out any damp/moisture ect
Did that originally, completely drained and re-fulled it, Still same problem, Currently I can't get the spark plug out, don't have a spanner that fits so i'll have to get one tommorow, might try looking at that again.
since you have done the basics i think its electrical
coil lead and cap are what i would replace
after a quick google it seems a common problem. im sure if you do a google you should be able to get the specs for the resistance that the coil should give off and test with a multi meter. the specs will give you a range that the resistance should be in
no electric shocks will happen lol
i just edited my above post have a look
oh and when you check your ht lead .... give it a wiggle whilst keeping an eye on the multi meter, what you are looking for is a break in the lead that could cause these issues due to it vibrating about



You might be able to download a basic manual for the bike somewhere rather that look at it on a webpage![]()
