Not syncing the flies. But I think u have to adjust the flies to the servo if u replace the servo itself. But it should already be good if you replace the entire throttle body assembly.

Did u fix the idle yet?

Gotchya. and no, so i haven't been riding it for the past few days because i dont think its smart to ride with that high of an idle. im going to inspect it tonight. so the idle knob is capable of lowering or increasing idle by 1500?

Yeah its there so u can adjust the idle to whatever RPMs u want. About 1500 is normal.

so I lifted the tank, pull the idle hose upward to access it with ease, and ended up turning it too much, unscrewing it completely. however, the idle never changed as i was unscrewing it. so the idle doesn't seem to want to change with the valves fully open. so I screwed it back in, but what i did instead is I unplugged the servo when the flies were doing their test and were a little less than full open. that helped the idle go back to 1500. but the rev range is limited to around 12-13k. when they are full open the rev range is higher but the idle doesn't seem to want to change with the adjuster when they are full open.

so i figure it might just be best to ride the bike until the season is over, as is, then when winter comes I can replace the throttle assembly. i just think it's best to get as hours as i can improving on the bike for now.

unless you think that's a terrible idea? the bike is running rich. that's the only issue i've noticed. and the power isn't all that linear since the valves are at a forced stop.

Alright man, youre mixing too many things up.

The secondary butterflies are only there to smooth out throttle response. Your bike should be able to idle normally and hit redline even with those removed. Since you have them unplugged in the fully open position, they should not restrict the engine from making max power....or affect the idle.

To make it easier to troubleshoot the issue, I would advise completely removing the secondary butterflies from the engine.

The Idle adjustment Knob: All this does is keep the throttle body valves slightly open....depending on how much u adjust it. When u turn the knob, it pushes a little pin further out, which pushes on a tab, causing the throttle bodies to stay slightly open. Turn it the other way and it does the opposite. Its a very simple mechanism.

Now, does the engine hit redline when u are in neutral?

alright that makes sense. yes the engine hits redline in neutral. as far as removing the secondary flies completely, i have read on it and it just sounds like its not worth the risk of fucking anything up throughout the process of removing them correctly. unless it's fairly simple and i'm looking at the wrong threads. i also hear i'll need to retune my power commander, but i don't know how to do that or what map is needed to compensate for the fly removal. i just feel i'm better off replacing the assembly.

Well, I was just saying removing them temporarily until u had all the issues figured out. Also, I had no idea u had a power commander on the bike. Try disconnecting the power commander so the bike is running on the factory tune.

If you are still able to hit redline in neutral but not while in gear, then u prolly have a dirty fuel filter or a weak fuel pump.

i think we have a little miscommunication. with the secondary flies full open and the servo unplugged, i hit redline in all gears and neutral. a couple days ago i unplugged the secondary servo connector when the flies were just shy of full open to see the effect i thought it would have. and sure enough the bike only goes to about 11-13k. the fuel filter is fine and i already replaced the fuel pump. it's already been narrowed down to the secondary throttle sensor being faulty and causing the secondary flies to not open all the way. so, the issue has been figured out. the solution is temporary right now though. that's why i was saying i'd rather just swap the throttle assembly because based on the trial and error, that should fix the problem for good.

i have a full aftermarket race exhaust, so i don't think having the power commander disabled will be good for the air/fuel ratio.

Idk, I would unplug it and do 1 test run to rule it out, it could very well be your problem

i've already test ran the bike with the power commander unplugged. it was intermittant as far as the effect it had. i took the bike out with it unplugged and the bike revved super smooth and hit 10-11k no problem (i didn't test it higher cause at the time i just wasn't ready to go higher). then i parked the bike and took it out again and the problem started again.

I tested the secondary throttle sensor and it was way out of spec. which lead me to believe that the intermittancy of the bike's performance was due to the sensor going in and out. then i test ran the bike with the secondary sensor and servo unplugged with the flies open and the bike performs to redline in every gear, every time.
