sandblaster:
Looks and sounds great!
bens87braap:
I changed jetting while the bike was warm and everything was fine.
Today I started the bike (Usually first second kick) 5 kicks to fire (I never used the choke it always starts without it?).
It was revving really high so i pulled the choke on and it killed the revs.
I now need to warm the bike up with the choke on for about a min or it revs high when i turn the choke off.
any idea why the changes i made it jetting and air mix screw has done this?
thanx for any help. Ben

got it sussed i just start the bike from cold with no throttle and choke on and it fires straight away. The idle is still a little erratic sometimes it climbs a bit higher for 2 secs or so? hopefully im not hurting anything i did a plug test in forth at full revs and the plug is dark brown now not black
