ill try the air filter many thanks ive ordered some stuff that can be pre cut ill try that.##
Regarding the electric start the starter motor is working as the breakdown people did a test and it started fine just looked at the connection behind the start button ( SEEMS INTACT) but when i press the button to start theres nothing, no noise no nothing?

??
Also getting a whirling sound when accelerating thought it might of been from hole in air filter but it doesnt seem to be could this be the belt
Ive also had it derestrited (so the garage tell me) and got a new cdi how else can i get a few MPH without exhausts do belts and rollers work if so are there any links to how to fit these
many thanks ppl
