manual idle adjustment

Anyone know how I can fit/make a race style manual idle adjustment knob/screw?

I find that in slow turns I tend to shut the throttle fully and get bogged down in the corner. I lose that smooth transition from braking to accelleration in the process. This is really evident in the back section at Winton in the three corners near and around the 'tree'. It would probably rear it's head at Broady too.

If i were able to adjust the idle up by 1,000+ rpm then it would let the engine run a little bit helping to keep up my mid corner speed.

I just need a knob I can turn that pokes out of the fairing in an easily accessed position.

This is pretty common with race bikes and mine is basically track only now.

Cheers
Wazza

All is OK now John.

Glad yours is on the way to being sorted too.

Haven't decided on the CCT yet as I've not got any excess noise... yet.

Just thought Id post pics of the install pretty straight forward. pics are a little blurry had to use phone, my digi cam died.

1.)flip over TB's take out stock idle screw and nut.

2.) put manual adjuster in about 4-5 threads showing out on the other side.

3.) route manual idle between the temp sensor and the little coolant hose out to the right side of engine.

Hope this helps others :thumbup::thumbup:

Nice how to qweesy!

John and Waz, the how to for manual tensioners here isn't comprehensive. I know 2 guys now that have blown up their engines following it, one going too loose and the other too tight. Rather than screwing in until you feel contact then backing out 1/4 turn, you need to remove the cam cover. If there's no cam chain rattle, leave the old tensioner in and measure the slack in the cam chain between the 2 camshaft sprockets. Should be like 20-30mm, but rotate the engine to measure a few different spots. Remove old tensioner, install new one, tighten until the slack is the same. Rotate the engine and check multiple spots. Much more reliable than the how to's or APE's method.

no error code?

where's the plug 4 that?
did u get a fault code?
any problems after?
I would like to remove the stepper motor but I though you couldn't unless you had the race ECU..... or until tuneboy / tune ECU make it so we can disable it

got a photo or a diagram...

bit dumb here!!!

Will the stepper motor over-ride the manual adjuster?

removed the air box again to check out the stepper motor...
I see the nut you removed - painted yellow like the idle adjuster underneath.
By removing this nut (& washer & spring), the motor would be unable to pull the piston in, thus opening the butterflies slightly... this is how it works, right?

How did you zip ties this?
Did you just slide the piston out of it's bracket?

Without anything to hold the piston (ie no nut), there is really no need to remove/move it is there?

Update

OK I just removed the little arm I was gonna just undo the nut an zip tie it but If you remove 3 bolts you can take the damn thing off here are pics

take off ISM nut
Image


remove these 2 bolts and your fuel rail

Image


remove the bolt holding the adjuster arm

Image


when taking off TB #3 DO NOT Lose this spring I dropped it and looked around for 30 minutes for it FUCK! :biggrinjester:

Image


the spring goes in the gap here

Image


once you have #3 TB off you can just slide the arm out and here is all the pieces taken out

Image


Here it is all cleaned up and finished

Image


I'm happy to say this did fix my rev then stutter/stall problem and no there isn't any CEL...... I have idle set to 1400 manually verify it in Tuneboy or TuneECU... I think my ISM was going out its nowhere near as loud as it used to be

so i've gotta take the boody throttle bodies off again...?

at least I bout some better tools other than a short allen key and a pair of pliers:laugh::whistle:

I assume the servo motor still operates but there is no arm for the piston to move now. Can the SM just be unplugged or does that throw a code??

Thanks for the photos qweesy.
Finally got around to some 'man' time in the shed. Job now done.

Now I need to get some fresh fuel and actually start the thing to set the idle level!!!

TIME TO TROUBLE SHOOT...

I did have it done, so I thought.
The bike has been sitting idle since the first of may (with the battery on a charger). Shouldn't be a problem... I did the idle adjuster, 520 conversion, new tyres and lock-wired everything since then but haven't started it.
Went to start it today. Knowing the idle adjudster hadn't been set, I expected things to be a little difficult but not like it was. I finally got a base idle set but the things runs like it's dropped a cylinder. The water light on the dash (RHS warning light) came on as well.
I checked that everything was connected as it should be and all seemed normal. The fuel was fresh premium, same as normal.

I've stripped it all back down again.

The little spring Queezy lost was not re-fitted, but I doubt it would make it run like a twin... it may however not idle cleanly...

I think I'll put the stepper motor arm back in and then get Juz to help me set the idle with TuneECU - that is possible, right?? This will negate the need for the manual adjuster as well probably.

Thoughts please????

you lost that little spring? It has to be in there because cyl 1 and 2 will open WOT and cyl 3 will only open about 85% at WOT without that spring and at idle cycl 3 TB will be closed thats why its running like that go to the dealer get that little spring..... If Triumph doesn't offer that little spring by itself take the one off in between cyl 1 and 2 go up the the hardware store and see if you can find a match if not then I would suggest ebay for a set of TB's


take off the tank again and look at the throttles when you turn the grip you will see what Im talking about.:thumbup:

Qweesy. You are good. I was looking at your pictures and reading your notes when I fitted my manual idle adjuster and I could not have done it with out you. Cheers.
But I did'nt even see that little spring until it dropped. I put it back where it belongs an all is good.

Thanks Smiley

:thumbup::thumbup: no prob man

done the spring fix and it solved the problem OR I had a lose connection or maybe both.

Still got the CEL. Did the 3 heat cycles but it's still there....
cool clear CEL with TuneECU, what have you set the idle to?
