Carbs-Jetting
Posted: Wed Jul 13, 2005 2:38 pm
person before me replaced the pipes on a 1982 kawisakia 550 ltd.I belive that they were raceing pipes.He jetted the carb's with over size jets[112].
It was running rought and always had to have the choke on full untill it got hot then I could take the choke of.It had quite a bit of power [torque].
I did notice a vacuum leak on two of the carb to block rubbers. I sealed them.After that it ran very bad no power to speak of.I changed the jet's to 102-98-84 -112-124 and none of that seemed to make it run correctly.
I adjusted the carb sliders so the vacuum would be the same.on the right hand side of the engine those 2 cyl would be 4 on the vac gage,on the left I think those 2 cyl would be 3 on the vac gage. Funny but it ran alot better with the vacuum leak.ha ha ha Mybe Ill drill a small hole in the rubber to create a vacuum leak.
What could have gone wrong?
