hi, picked up my 07 sherco yesterday and i also have no spark and am at a loss so gona follow your post and hopefully get a answer.
i've cleaned carb and all filters,new plug. i've pulled apart left hand switch gear but how do you isolate kill button??
mine has a button similar to a horn which you press to connect a black and yellow green wire which kills the engine,if these arent connected am i right that circuit is good to go? so how do you isolate it. just about to check earth on coil and connectors for crap and corrosion.
hope you get sorted.
