I tried to do a throttle body adjustment with a Motion Pro SyncPro tool. I followed the instructions and calibrated the machine. I then connected all 4 vacuum hoses from the bike to the SyncPro. Of course the reading was out of whack because the throttle body has probably never been adjusted. Well I tried adjusting it so the bars would all line up but the reading in cylinder 3 was way to high. I screwed the adjustment screw in till it couldn't go any further and made the reading a bit better. I had trouble keeping the idle at 1300rpm, etc, so I gave up, connected all hoses again, put all the fairing pieces back together and called it a day. Well after taking the bike for a ride I noticed that the rpm's don't snap back as quickly anymore. I can sit there and rev the engine till about 3000rpm and it will stay there for a short period of time and get back to idle....but a lot slower than before.

What could've caused this? I understand that the adjustments I made were to control how much fuel each cylinder gets.....I don't think it should cause the problem I have, but I could be wrong.

Anybody else have the same problem. Please help! Thanks in advance.

 

Is your throttle cable sticking?

 

Sounds like you need to adjust your throttle cables.

 

cable,,, if it was a dirt bike i would say the slide has some sand or dirt and is hanging the slide

 

does this adjusting throttle bodies really help anything?
