okay i have a problem i go out for colleg this morning and the bike wont start. i tried it with the choke on/off everything. so i come back and i try to fix it, turns out it had something to do with the spark plug/cap? it starts now but it splutters like fuck (the only way i can describe this is like, when ur bike isnt warmed up and u ride it from cold, and it feels rough), it will not even idle. i thought this was a weak spark but it only does this up to about 10-15mph then the bike rides fine, untill it drops on speed again. i thought maybe it could be my rollers, but why would that affect my idle and starting? any ideas? im at a lost here.
i was thinking it was bad jetting, but then i thought why would a carb fall out of jetting? that never happens surely. and ill have a look for an air leak, but it doesnt even idle with the choke on :/ but cheers for replying
