Throttle Body Adjustment

[Budo]

I have some questions... ones that I hope that Bob or Scott, or anybody else with a great knowledge of motorcycle maintenance could answer.



First question, what are the symptoms of an "out of adjustment" throttle body/bodies?

Second, I know from the maintenance manual that you can adjust the throttle bodies electronically using the Triumph diagnostics tool. Has anybody here done this with a Tuneboy? I e-mailed Wayne @ TB and he says you can, but I just want to see if any of you have done it already.

I had the dealer do it. They just plug in their diagnostic tool and check it. Took 5 mins. and did not charge me.

Me too... But I had them do it while they were doing other work so they didnt charge me. Don't know what it would cost otherwise

Nice... two answers that clearly does not answer either of my questions...

Douche buckets... :laugh:

Thanks anyway though.

First Q. They would have to be WAY out for you to notice.

Second Q. Don't have a tunegirl. Ask someone that does. Like our buddy whats his name.

I've never done it, nor have I seem where to do it on the TB software.

My throttles bodies are just a little off. Number 1 and 3 are the same,,,but number 2 is a hair off. When i had it dynoed.....i was shocked to see such high hp numbers...so i never tried to sync them with the Tuneboy. To tell the truth,,,,i was scared to screw with it.

If I had to do it...i believe i would ask FLUX for some guidance first.

alright...lets see if this helps....
my bike is getting work done on it..altenator is knackered.
i noticed that when i'm in neutral the bike revs normally. when i stick it in 1st the revs drop...ie throttle bodies. so i asked em to check it...wasn't gonna bother but it was getting work done already.
this is what i was told by my mechanic. he says the diagnostics tool or tuneboy will tell you if the bodies are out or not and by how much. you then have to get to them and MANUALLY adjust them, the computer itself won't.
Could be dealer "i want more money" bullshit but i trust em.
hope that helps a bit

Ya know i think you are right and i forgot about the posts i read on the subject. Supposedly the adjustment is a screw and locking nut.....and.....you adjust 1 and 3 to be exactly the same as number 2 because it has no adjustment.

I don't think dropping into first gear has anything to do with lower revs...or TB adjustment though.

I went through the service manual and checked it out, and you're right.

The manual says that you can balance the throttle bodies using the diagnostic tool, but when you go in depth (100+ pages later) it basically uses the diagnostic tool as a measuring device. You start turning the adjustment screws and stop when the diagnostic tool says it's balanced.

sorry...i'm terrible at explaining symptons and faults..
i'll try though so bear with me....
what i was trying to explain but didn't is that the bike idles normally in neutral. when you stick it in 1st the revs REALLY drop and the bike runs "lumpy" almost like it will stall out. because it is ok in N, it means it can't be the normal symptons, airbox, sparks, timing etc. i know that probably didn't help much, just kinda take it on faith :laugh:. the throttle bodies were slightly out and are getting adjusted


(probably confused the matter more than helped it :whistle:)

Well mine doesn't do that. The only way revs can drop when in gear is because you have the cluth pulled in and the clutch is dragging. Either too high an oil level....or a mis adjusted clutch cable will do that.

from my understanding, and please correct me if i'm wrong, one of the key symptoms of TB problems is rough idling and stalling at low revs. (once all the other symptoms have been excluded) in case i didn't mention, the clutch was pulled in in N and 1st to eliminate it as a problem.
again, i maybe wrong just stating what i thought.
from my understanding, there was a by-pass port at idle, and the TB's only started working when engaged in gear or rev'ed, hence the drop in revs when the engine is engaged

Let me start over again. If your bike idles at the correct RPM when in neutral......then it should idle at the SAME RPM when in first gear with the clutch pulled in. If it doesn't...the clutch is dragging.

If it doesn't idle correctly in neutral....then something is wrong. I'd guess fouled plugs. I wouldn't think that the throttle bodies would be that badly out of adjustment.

[Budo]

Hey Al... ol Bob-o here must really like you. I don't think he's called you an idiot even once on this thread... :P

it would seem i stand corrected, apologies...i'll check the clutch and keep you posted:thumbup:

That's because the other board is full of paranoid fools that must be high on Meth or something.
Smooth move making Scott a Mod though. That'll force him to post less here...and more over there. Ya think that was the plan?

Nice theory... :coolgleamA: but I doubt it.

Scott is just an all around superb guy, and I guess Heath noticed it more lately that he's been doing the BOTM.

Superlight also wrote a PM to heath about Scott... I think that's what opened his eyes ;)

[Scooter Scott]

Smooth move indeed. It came out of the blue. Noam asked me to be a mod over two years ago and I turned him down. I really don't care one way or the other. I'm still not even sure what a mod is supposed to do.:smile:

Well for starters mod = modifier..

So all you do is just go around and modify people's posts in order to make fun of them. You should try it out and screw with Jstu's posts... :trampoline:

Before they ban him. I better be fast.

See the latest one where the guy posted a vid and sped up the video to make himself look blazing fast? These people are stupid. They think they conned everybody....and nobody would notice. I been riding that road since 1986.
