fuel ratio/jetting 26mm carbie

[anarchist_ways]

i got a new 26mm carbie + inlet, and now when i pull the throttle down full bore it bogs down and almost dies! it used to mono or go instantly. is this too much fuel? im not sure which way to turn the jetting screw either so im kinda stuck! any help would be appreciated.
cheers

just turn it one way and se what happens and then turn it the other way and se what happens

Look at the Sticky about Mikunicarbs!!

there are several excelent articles already written on this subject. I did just what was recommended and my bike starts if you look sideways at it has great performance and accelerated perfectly, formula is 105 main, 20 intermediate and all the way in and out 1.5 turns on the air bypass screw. If you have no manifold airleaks it will be perfect, cheers

The piolet screw dosent do anything if you have full throttle problems. It is more likley that you have a air leak around the manifold. Deekay is pretty much right in that you probably need to rejet the carby.

normal gasket sealer is ok to use? ill try the 1.5 turns, not sure what its at at the moment!

Why did you change the carby in the first place?
