ELL...connecting the MAP sensor proved to REALLY, and I mean REALLY INCREASE the vacuum signal to it and SEVERELY richened up the air/fuel ratio, enuff where the skoot ran like crap and was drinking gas like it was free!
I firmly believe in having both cylinders feed vacuum to the MAP sensor but this will require a MAJOR retune, and I'll have to check this out when I can get it back on my dyno. For now I'm just gonna plug up one hose to get my performance and mpg back! RACNRAY

Started the skoot up, it ran for 8 seconds then shut off. I could restart but it wouldn't stay runnin, couldn't even get it outa my shop. This time pulled the tank off, put everything back to stock (rear cyl connected to MAP sensor) and wala...runs normally. Since the MAP sensor is not connected to multiple cylinders it receives a vacuum signal only once every 2 crank revolutions (when that rear cyl is on it's intake stroke), that equates to one voltage signal at the ECU which is obviously timed for the proper firing order of injectors and ignition timing. At least I found out that with my properly sealed intake system my idle imbalance was miniscule, not even enuff to make any difference. Nice to know. A WHAT? RACNRAY

i meant to ask if your running a programmer or tuner or some other type of signal modification device. i have some rubber plugs in the freezer to make some vacuum adapters for the intake runners to test seals. not pleased with the fact i have to test all this with less than 2000 miles on the bike because the 120lbs dealer mechanic says it runs fine across the parking lot. the whole reason i bought a metric was be able to jump on and ride. looks like maybe i got a lemon.

Check out this link to my thread on intake leaks done back in 2011. Do the mods (except the machining on the manifold and t/b as the Thunder intake gasket (not available at that time) is the new fix. Tightening up the 3 t/b bolts do nothing for crushing the orings as the stand-offs on the t/b prevent proper o-ring crush. Virtually everyone that has installed the gasket has had positive results and I would HIGHLY recommend you re-check ur idle balance. RACNRAY

the screws on the throttle body only balance the air flow at idle speed when the throttle plates are closed..use a guage to adjust not your ears or imagination ... that idle circuit should have no effect on anything the engine does beyond idle

I'd like to get a thunder gasket, but just checked and it was $16.27 to send a $6.49 part.

They adjust the shipping to the actual cost after you place the order.

I don't mind paying for shipping, but as long as it's realistic.
