Ok thanks I’ll look into those, I thought bout changing tanks but then the ones I’ve found look like Harleys so I ain’t gonna go that route. Lol

Something told me that didn’t look right, cause I near bout ran out of threads messing with them that day, I got to figure out where I’m going wrong on the syncing.

Does the pully stop have to be in a certain spot to bench sync. I’m missing something, cause off a bench sync it’s idle is to high, backing off the idle adjustment screw don’t work cause I run out of screw so I have to adjust the needle slides and they so far in I almost run out of threads.

You adjust the idle screw about 1/4 way THEN do your bench sync.

Ok, what bout the adjustment screws on the slides at the top, u shouldn’t almost run out of threads should u, there’s a flat washer and a lock washer under the nut , I checked partzilla and those should be there.

You should be able to adjust them back about 1/2 way.

Slide cutaway doesn't affect idle.
They affect mixture strength from around 1/8th to 1/2 throttle.

Ok thanks, and the shaft that the needle slides bolt to that’s pretty much straight forward there’s no way to put that in wrong is there? All bolts are in and that flat piece with the notch in it in between the 1 and 2 carb.

Like I said, the throttle slide adjusters are in too far (not enough threads showing above the nut). This causes the slide to sit too far open. You need to loosen the lock nuts, adjust the slides so you have a few threads showing above the nut, and then set the idle down with the main adjuster.

Ok, gonna look again tomorrow, I know when i would raise the screw to get more thread above the nut the slide would rise and the bike would idle up. So I got to get a better starting point, I think I’m just doing it wrong to start with.

My bad, I think I'm the one that's got it backwards. Maybe your throttle adjuster has the wrong spring on it?

Idk, cause when I set my idle screw so there is a gap between the stop and throttle pully and I try then to get the gap of 0.7mm or a 20ga wire in between the slides and the bores I get close to running out of threads on the adjustment screws, I feel like I put something together wrong . I’m gonna keep at it till I get it.

I've got a couple sets of VM26's here and when tweaking the throttlestop I can make the slides completely close. I think you (somehow) gotta figure out why the slides sit open so far.

Agree with Steve. In the slot.
I have a couple of Z1B's restored, an '80 KZ1000LTD restored, a 1981 KZ550 restored and a 2008 KLR 650 for off road fun. My wife has a 2019 Suzuki DR 650 for on and off road.
