Ok, this is my buddies bike but I mostly end up jetting his stuff.
I am not looking for specific jetting recomendations, but just in general jetting with the RB carb mod. I think that is what it is called with the plate cut in on the reed side of the carb. Also this bike has had the crapy mikuni carb replaced with the PWK.
The way it is jetted now
PJ- 55
slide-?
Needle- R1469M which is 1/2 clip leaner than DGK
clip-3
main- 155
the way it is set up now, it has a very slight rich coming off of idle, the air screw has little if no effect. The idle screw is turned almost all the way in. To ride it, it feels almost spot on below 1/2 throttle, but is a reluctant starter.
I think that the 55 pj is overwhelming the idle circut and requireing the idle screw to be turned in all the way for the air, renderig the air screw useless.
I am thinking of changing the needle taper to a "C" less taper, but go richer on the straight section to a "J" and drop the pilot to a 48 or less in hopes of droping the slide back to a normal position to help starting.
Does the RB cause strange jetting woes that I will not be able to jet around or is it just a matter of sorting out?
