dtmf Posted November 24, 2009 Share Posted November 24, 2009 in the manual for my carb's it list's the main jet's @ diff sizes for the LH/RH. when i changed my intake and exaust i changed my jet sizes as well. i went up 1 size on the main's and the pilot jet's . i kept the same size diff on the main's for each carb. the side that has a smaller size main jet now run's lean . why do the carb's have diff size main jet's . can i use the same size main's on both carb's ?

I've been wanting to get out today too, stinking Black Friday crowd has been bad everything backed up. Darn, the neighbor just went by, he's put some V&H pipes on his sportster and they sound good. IF he can bear it so can I, talk to you later..... Link to comment Share on other sites More sharing options...

Today will be our last goooood day for a ride as temps are headed to high 20s and low 30s for overnights and cruddy clouds during the day with chances for rain. Guess we are getting to December. Can you buy the shims you need or are they in a package? Link to comment Share on other sites More sharing options...
