gives you manual control of the idle and removes a part that is known to give trouble and is expensive to replace.

gives you manual control of the idle and removes a part that is known to give trouble and is expensive to replace. The 675 is RACE kit J; it removes the ICAV, FFS read it will you...072717

hi, think you just remove the mickey mouse idle valve, block up any holes for the pipe work, and fit a tab/screw to set tickover like we used to do in the olden days.07 someone on here has done it, so may be along shortly to give you the full story.

Just doing what you said will not work.

The idle air hoses are the ONLY way of getting air into the inlet manifold when the bike idles (Throttle bodies are completely shut)

In the olden days you'd have a small grubscrew to slightly hold the throttle bodies open slightly (or with 2-strokes) a small bypass valve.

There is a small tang on the throttle stop which bears on a small grub screw on the fuel rail support. You can replace this with a longer screw if screwing it in fully does not give you enough idle.Its a bugger to to so its a airbox off adjust air box on etc. to get it right though. You will then have to use the throttle to start to get a fast idel...hence using the 675 race kit which gives you a manual 'choke'....

I want to ditch the IACV as well but was wondering, what is done with the wiring if you just unplug the IACV would you not get a fault code up?

Hi X - Man just found a link to the part and its just a long , esh rod with the grub screw thread on one end and a small nob on the end, No manual choke set-up to be seen.

freakshow :- "what if i ran the inlet hoses for the throttle bodies to the airbox direct / possibly work? "

Yes, if you had a valve in between to adjust the air flow..which is merely what the IACV is.

If mine wasn't so perfectly fine, I'd experiment with a voltage adjustment knob for the IACV.

WOuldnt do away with the IACV yet until carefully checking for all possible leaks in hoses/joins plus the iacv seals first.

hi freakshow, hope these photos help. The cable is an old bike speedo cable i had lying around which i soldered into a M5 set screw. The clamp on the other end is a bit crude but one day i will improve it. The only problem ive had is a few fouled plugs, because before start up i used to wind the adjuster in , giving too much fuel, now i leave it set to the previous ride and as soon as it fires adjust it to about 1500rpm till warm. It works great! Let me know how it goes, cheers, Rob.

I found that the adjuster from a Honda sp1 fits (flee Bay £5) and the way it’s made you can use a cable tie to mount the adjuster knob to the frame tube at the same place. Also found the starting just the same, just fire up 1/4 turn in till hot and trim down all ok, Ho and my pal runs a big freezer where house so just to see parked it up in the holding bay at -8 C for most of the day and it fired up 2nd spin no probs

I fitted the 675 race kit adjuster on my 955i Daytona, just needed to hold throttle open slightly till warm, then it idled perfectly:thumbup:

Don't know how it is to live with because i sold the bike a couple of weeks after fitting it.

Also i think you are better off fitting one of the Honda adjusters as mentioned above, much easier to reach!

freakshow, Unless there's something drastically wrong with the IACV circuit, there's no reason to remove it and if it's removed it will cause a MIL.

Justin, i promise you, if it gets to the point where you have tried everything to get your bike running right without it stalling you will think about doing it.

Ducatis are fuel injected but they don't have all that unnecessary crap, they use a fast idle switch on the throttle untill they are warm enough to idle:thumbup:

Oh and btw, i left my IACV wiring connected and it didn't bring the MIL light on.

kevn, I left my IAC connected also, no problem. One of the four wires to the IACV will eventually go open and I can fix it properly, but for now that little valve has it back on the road. It does require attention until it warms enough to idle tho'.

kevn, The link just worked for me. It's in "Problem Solving" titled "Picture of Defeat" in case you still have problems pulling it up.

The IAC is still connected, but I added a crutch.:beatup: The IACV won't idle down from the 2K RPM warm-up mode and I've proven the trouble is in the wiring harness. The little valve restricts airflow into the IAC manifold to hold the ~1200 RPM idle.

Fair enough, and to be honest if it had been a bike i was keeping, i would have replaced it:thumbup:

I was in Destination Triumph a few weeks ago and there was a IACV on the counter and the parts fella reckoned it was about £70 iirc, so they are not that expensive.

J-Zeus, You might've just jinxed yourself!:speechless:

The original IACV's needle mount had broken, jamming the needle to the side of the seat. I thought the new IACV would fix the problem, but no joy in that.

Slapping, bending or just twisting the wiring harness would fix the high idle (originally at 3K-3.5K RPM), 'till next start up that is when the IACV is cycled at key on. I think that there's a ground problem, at times that will eventually fail fully.

Mine went sideways a few years ago. (I snapped the plastic when replacing it after a service:blush:)

I just scavenged a new one of Big Dave's wrecked Daytona before the Insurance man got around to viewing it:lol:
(I also scavenged loads of other bits and pieces:lol::lol::lol:)

Moral of the story: Just wait a few weeks. You can always rely on "Big Dave" :tongueout::lol::lol::lol::lol:

kevn, I wasn't as lucky with two of my cars this year, both required new IACVs!:angry:

On topic, just to be clear, I don't recommend my 'crutch' as it's not a 'fix'. The IACV will close completely under throttle, the manual valve can't so there will be a bit of fueling problems, primarily at slight throttle openings. Sooner (hopefully) or later the problem will become severe enough to light the MIL and I can isolate the problem.

Aye T, it's the manual idle adjuster for the 675. Gonna have a go and if it doesn't work I'll just connect the stepper again.

I have some 470k ohm resistors lying around, would you know how to test the steppers resistance buddy?

A to D and B to C both should be 47 to 59 ohms

Thats the two outer and two inner connections.

By the way, to make the 675 adjuster work you have to cut into the right hand underside corner of the airbox
