Thanks for all the pics Dan. You got your PWK from the same outfit I got mine from, JFG racing. I see you have the notch in the hood, but your box doesn't make any mention of "38mm" (like mine & Sneezy's), and you have that "40" etched on the side of your body.

You are right, hookin that cable up is a real tricky job. Unhookin the throttle grip end makes it a lot easier to juggle the slide end.

I suggest you take a bunch of baseline data and post it.

Remove the main jet and pilot jet, tell us what size they are.

Remove the idle mixture screw. Measure the fixed air bleed. It should be about .075". The shank of a #49 drill bit should go in, but the shank of a 5/64" should not go in.

This is the main air bleed.

A #35 drill bit fits loose, a #34 just fits, and a #33 won't go. If your needle jet is the same size as mine, then a DGK slide needle works excellent. The slide needle mine was delivered with worked OK. The DGK works excellent. This is the jet in question.

You probably want to have a #35 pilot jet in hand (along with #38 & #40). It is only available in genuine Keihin, the generics only go down to #38. One thing I found is that the slide needle affects idle mixture. Even with the #35 pilot jet, idle is a bit rich. Not bad, but a little fatter than I like. The DGK slide needle helps with that. Of course, that's all dependent on the size of the needle jet, if it's larger or smaller than .111", then you will have to figure out which slide needle is appropriate. There's a good chance that the as-delivered slide needle will work OK. If it gets to that LMK, I have a bunch of info on the slide needles.

If you reach the limit of patience with that throttle cable, the Barnetts that Lancer sells for the VMs work good (at least on my 2016 LS they work good).

Take heed on the ABS elbow. See my comments in my other report. The ABS falls apart. I switched to PVC. Hope that holds up better.

Sorry fellas, and ladies as well if you’re listening, I got a leave on a weeklong work trip again tomorrow. Good news is, when I get home my canon filter my rear bearing and my jets it will be in wahoo. I got to ask though what is with all of the pink vent tubing that comes with the 40 mm? I noticed in your picture you have a couple of them capped off? I was out in my shop this morning in my pajamas at 6 o’clock installing the carburetor lol like a kid I couldn’t wait and yes it completely ran like crap.. I think her with her for a little bit but I think it was real Rich…

Jetting is everything. Well, imho... everything I have read from different motorcycle forums, and experience, this has to be right. And takes the most trial and error. On my Kawi I am wrestling with sync'ing the carbs (inline four). Fun stuff! More trial and error, but more on a mechanical side. It boils down to feel with threaded adjusters. I am thinking this single should be a lot simpler. In theory, anyway! Shocked

Yep, that sucker comes with hoses all over the place. It sort of resembles a plate of spaghetti. I think it's a dirt bike carb. Keihin refers to it as a "quad vent". I think all the vents are intended to help keep the engine from filling up with fuel when the vehicle is laying on its side in a mud bog.

You can cap off the nipples on the side. Like this. Just use the top nipples.

I just route that down behind the engine. Make sure it is not over the exhaust pipe or muffler. You don't want it dumping fuel on the hot exhaust.

Reply #42 - 12/07/21 at 13:27:36 Good deal, also I wanted to ask you did you buy the long sweeping Street 90 or a regular street 90 even though I’m on the road for work this is what I picked up this far… The long sweep is just about a half inch longer than a regular 90 I believe…

Reply #43 - 12/07/21 at 13:31:27 Also I would be much obliged if you were able to tell me the exact length of your throttle cable? Did you buy it or modify it? I keep looking on Amazon the ones for our particular carburetor are like 70 some inches long nowhere in the neighborhood of 32 to 36”… but I think you said your bike was a 16 mines an ‘01

OK, didn’t know if I should start a new post or not however the Pkwy PWK is installed. It came with a 170/55 set up on the Jets. It started and ran but like crap. Mr. Mike, I was wondering about the jet set up I forget what you said. I did the K&N mod like you did… May be a little lean I mean if I get after it and then roll off ,I got some Poppin… feels under powered as well. I’m getting a slight pop at gear change as well.
