Just finished reading an article about installing the 58mm throttle body and 90 degree filter on a 103 with cams and pipes. It said that it really woke up the bike. My concern is too much fuel for a relatively mild engine. Kinda like a double pumper on a small block. Has anybody done this or what's your opinion? My dealer has never done this without head work or radical cams. If I can remember, I think I have 354 cams and S.E. full system with cats in the mufflers and super trap end caps. Thanks in advance.
