I'm thinking of attaching it to my flexible screwdriver but not sure that will give me what I want. If we can make a $5 balancing tool, manometer, we should be able to come up with something for those mixture screws!

they don't have anything that will fit the VTR, I emailed them and asked. My problem here is that whenever something is made to be "tamper proof" I have to find a way to tamper. This will drive me nuts until I solve it.

the D socket on jetsrus is the motion pro brand, so are you saying that motion pro sells different length D sockets with diff parts #s? Strange.

Oops silly me. I didn't notice that was motion pro as well. It must be just the way the picture looks. The scale don't always show too clearly in pics! Well that's the one to buy then. If it's the same as what I got with my kit they are about half the depth of a standard bit, say, compared to a Snap On screwdriver bit.(:-})

Found a company that makes a neet idle adjustemnt screw for our bikes.....I think 
Here is the link to this company in CA. EZ-Just Mixture Screw - On Sale - CV Performance
Now, I have tried reaching them by phone, with no success, and I'm tired of the email thing since many times I get back an uncomplete answer. So, my question to all of you is, has anyone heard of this place, and if so, can you guide me to them if at all possible. Or even better, if anyone in Caly, can you please look into this for me ? I would be very greatful, since I don't want to blow off 40$ on something I'll get, and have to ship back. Oh yeh, checked their shipping fees to the great white north...25$ snail mail to my place. So make that 65$.

Iv'e often wondered whether the Harley ones would fit our carbs. But like yourself I don't want to purchase only to find out they don't fit. We need to know the thread pitch and depth so we can compare against ours.

If you shuffle through their web site, they have two models. One for HD, and one for metric. My link is the one for metric. The question you are asking about thread pitch, is what I am looking for as an answer. But as I mentioned, I can't seem to reach anyone with their 800 number, and really tired of the email.

J&P couldn't figure it out themselves, and they are the ones who recommended I communicate with CVP directly to get this info.
Plus, the phone options are available for none authorized dealer.
Say Hawk, that's in your neck of the woods, perhaps you'de be our friendly neighborhood spiderman for this one....would you ?

Well I got a reply, it arrived in my spam box. Basically I asked them it they could tell me the thread pitch and the depth from the base (bottom) of thread to the point of the tip on the needle. Their reply was brief and as follows.
Not the most helpful customer service LOL but at least they replied.
if I get the time I will try and get out and measure the thread pitch on my spare carbs tomorrow. It's a step in the right direction anyway. If the thread pitch is the same I will pop them another question and see if they will tell me the depth of the needle from the base of the thread and if it's compatible with Kehin series 21 carbs.

we use an M6 .75 thread to fit all Harley Davidson CV40 carburetors.

and pitch is accurate to our needs. If base of thread to tip is 15mm, then we
are in business !
As for customer service, I agree. We now live in a day & age of don't bother
me unless you buy. And even then....that's a tough one for most.

I never heard back from them on the second email 
and did not bother chasing it up.
I just use my motion pro screwdriver for adjusting mixture. It was a little tricky on the rear cylinder at first but the more I use it the easier it gets.

I'm finding it difficult to "feel" when the tool is properly seated on the damn screw! Once on the screw properly it doesn't always turn smoothly. I suppose it will take practice, tight space to maneuver in!
