guys, i'm pretty confused...
...i've read many differing opinions on this subject...some say TBS needles, no shims...some say shim the TBS needles cuz they're too long...some say use Thruxton needles, and others say the bike'll run too rich...can i get some feedback from guys that are using TBS needles w or w/o shims? also, while i'm at it...what about vaccuum port drilling? i thought i'd do that at the same time, but want to make sure there's a definite benefit to it. any probs encountered by those that have done it? btw, i use the term guys in a non-gender specific way...
