    hey after fitting my 70 bore kit my bike was bogging when more than half throttle applied (second hand bore so already worn in) so i down jetted to 86 and it wouldnt start.

    so i up jetted ti 105 again and still wont start.. well it goes for 2 seconds and dies

    anyone know how to resolve this or had the same problem? cheers

    I would ditch the oil pump and run it on premix 35:1, then down jet to like 80-75 and go from there

    take carb off, set the needle to the 2nd or 3rd notch down, put 86 jet in

    check everythings tight and for air leaks

    it bogs with the 105 jet because its far too rich
