I bought my 77F last summer and when i got it it wouldnt idle without the choke, and wouldnt rev without turning the choke off. With my limited knowledge i decided it was running lean. What i did was pulled the carb bowls to have a look at how clean the jets were (just in case) and they were clean, then i turned the adjustment screws out a few turns to richen it up. It idled and ran great for the rest of the summer. (I also took off the crappy pods and put on a stock air box i had laying around) Even though it runs good now, the idle screws are turned out much farther than stock and i know its not set correctly. I assume i need to adjust the needle clip positions, but i just didnt have time to pull the carbs and mess with it back then. Well, now i do.
While i have it apart i was wondering if i should up the jets to 120. If memory serves me it has 110's in it right now. Some fairly knowledgable 750 people have told me it would run better with 120 mains, and i figure if i have to take it apart anyway, now would be the time.
So, my question is, what jet size are people running in their F2/3's and where do you have the clips and idle screws set? I have a stock air box and filter as well as stock HM410 exhaust without baffle.
