Hi would anyone know how I would find the correct jet sizes for a MIKUNI 40 MM pumper with these markings (T Q Z 1) AND (V 40 W )  would this make a good carb for an 85 evo?

Cheers

Bourkie, I doubt there's such a thing as "correct jet size" for any Carby.
Way to many variables depending on the engine setup with Exhaust and Air filter etc'.
Mikuni have a very good tuning guide on there website to walk you through jetting.

Personally I use a digital logging wideband o2 meter for tuning.
A 40mm Mik' should work well on an Evo, or a late 40mm CV would work also.

 hi,   if it's the 40 mm smooth bore flatslide carb  for the harley they are a good carb ,   it should have the cable wheel on 1 side ' with a short  idle cable  adj under the body ?          idle jet  17.5 m.m. idle air bleed 0.9 m.m., main jet about 1,75 -1.80 m.m.  you can play with the main tube & main air bleed but if you don't know how  don't  i have jet's & K&N air cleaners in stock for this model carb,  

people through them out for a 42 m.m. & i collect them as i like these carb's  & can get them working good   the slide can rattle @ idle if it's worn  but when on the throttle it will be good  as the gate is open & no suckion on the gate @ idle ,  no worries

  stock idle air bleed is 1.1 m.m.  & is  too lean  if yougo to a 2.0m.m. idle jet it;s too rich ,     i wish i was too - rich 

Well there you go while I was thinking about buying the Mikuni carb someone else actually paid the $100 for it and I am still looking, so it might end up being a CV off a 96 fatboy if nothing else turns up

thanks for the help guys
