Done a bit of trawling and checked my carb jetting as per when I last had it apart and this is what I found this on 4Gear web site:
Recommended jetting : idle jet: 42 (54531607042). jet needle: OBETP - 5th position from top (59031034100). main jet: 168 (54531623168). leak jet: 70 (54631085070). air screw: 1,5 turn open. pump spring: green (SXS08250030).
I currently have fitted all of the above except the Leak Jet which is an 85. any ideas what I should go to?? on a std 250 some say as small as 50. is this to small for a 280?
