mikuni tmx 35 needle settings advice needed

[rbgaz]

hi all im running a tmx 35 on a rb22 ,i have really bad spluttering and boging at around half throttle it will clear when u in the power band and over 55mph which isnt allways pratical ,i had a 350 main with a 25 pilot and a 58 needle on second clip from top, ive now changed to a 330 with a 20 pilot and on top clip on a 58 needle which i think is the leanist needle in the leanist clip u can go but it made no diff at all, any ideas ? cheers

i have few weeks ago put new rings and reed petals and also a brand new slide it allways splutterd a bit but nothing like this i had a large main jet in for about 4 years due to holing a few pistons, could it be possible for the needle to be worn out ?

Quite common for the fixed atomisers to wear......the needles can too, but that's usually visible. But for the cost of a new needle, it's worth trying before you replace the carb.

try a new stator

Will test it today I've also got a kytronic spark thing on so going to take that off and see what happens
