    I installed pod filters and a new staight through exhaust ( scored a free Harley sporter exhaust via Graigslist!) I was thinking of using some 120 main jets. Any body have any suggestions?

    You should put that you have a 650 in your signature.
    Usually you would try a 114 to 116 set first and watch your spark plugs for color. Search for threads here about doing "plug chops"
    Prepare for lots of experimentation.

    120's may do the trick... It really depends on what bike you have though... ?

    Sorry Guys,
    1980 XJ650.
    Anybody try to slow the air flow @ the top oval of the carbs? Rick-o-matic had a post about it a while back.
