shoulda asked what the idle is! lol *facepalm*
oh.. you either have a vac leak or the bike needs the carbs synced. i'll put money on needing synced.
carbs work off airspeed and port velocity.. most definitely, if the idle is low, the air intake and port velocities are low.. and in EXTREME cases (normally on SUPER tuned race motors where VEs are over 110%) the cam profile coupled with port harmonics may fuck up the running so bad that it simply WON'T run.. these bikes are cammed VERY extremely..
for an example, if you're familiar with toyota's supra, its pretty much the be all and end all of tuner lust.. the car STOCK with turbo came with 320CHP.. just a cam swap TO a 264 cam, a little degreeing and some tuning work puts the car up over 600 WHP.. you figure, most sportbikes come with 264 cams STOCK.. thus why the current rough power to displacement factor is .2 HP/CC
that same supra with THAT number would make 600HP WITHOUT a turbo, on pump gas.
a viper would make 1680 hp on pump gas with no turbos.
my f250, sans turbo ( its a 7.3 powerstroke, highly tuned..) would make 1460hp..
so, needless to say, bikes are tuned and built to the extreme right off the bat, so any LITTLE tiny thing that's 'wrong' with fuel or spark throws it WAYy the hell off..
jeff, its just time, man.. i have a ton of time in the field.. grew up with this shit. been around cars and bikes my entire life. was fixing lawn mowers for my pops when i was 6.. built my first car when i was 8 ( VW rabbit with a single cam 1.8.. old skool mechanical fuel injection) .. theres still plenty of people who have forgotten more about this stuff in the last 10 minutes then i'll learn in the next 10 years!
