I've got a bit of a problem, normally the blue beast starts 1st kick from cold or hot, but recently from cold I'm kicking my nuts off trying to get fired up, then it runs very poorly( won't idle). Here's what I used to do - - Pull choke out - Piston at TDC - Kick - the beast's alive !!! Here's what I have to do at the moment - Pull choke out - piston at TDC - Kick - nothing, not even a murmer - Piston at TDC again - Twist throttle to give a squirt of petrol (my old 98 model needed this to fire up after standing a week !) - Kick - starts but dies very quickly (not touching anything) - TDC - Kick - nothing, not even a murmer - Kick - nothing, .........etc Petrol coming from float bowl under carb (via pipe) After alot of sweating, cursing etc, the bike starts, runs rough, won't idle, need to keep the rev's up with the throttle. Riding the bike with the choke off (feels like the bikes serging, & back-firing). Once the bikes fully warmed up, the bike starts 1st kick again & perfoms like it used to do. The jetting I think is standard (never had it appart - scares me !!!) Exhaust is a white brothers E series 6 discs WR timing New spark plug (started ok when fitted & ran ok until above for 3 weeks) I've ordered 45 pilot jet & 172 Main jet (info from tables given on 'Technical'at beginning of forum) Am I on the right lines with the above problem ???
