The main jet has more effect at wide open. If you are pulling towards redline good at wide open then you may be fine with the 128. Yes moving the clip down will lift the needle and will richen it up through the whole range. I worded it that way as it can be confusing to just say raise the needle. No stupid questions..you are on the right track. Your dynojet instruction sheet should have a nice diagram showing the relation between pilot jet, main jet and needle position in relation to throttle position. Glad you were able to complete the cam mod, it is a nice step up in performance for free.

 

Vee, I have no data regarding AFR with lid on, or with lid+snorkel on.. I could only guess what happens to AFR when you do lids and snorkels, and I'd probably be wrong. LOL

NorCal, your at my elevation with cooler air than I have. This means you'll be running it even more lean than me - not good, but we have to set it up the best we can ... Pull the lid, put in the 132, put the clip one or, even better, 2 notches lower on the needle, follow stage 2 for the air screw and let'er rip. I spent numerous sessions on the Dyno to figure out the above recipe. My Dyno AFR charts are all available in here.. What cost me a few hundred dollars in dyno runs is free to you...LOL

If you've re-timed the cams correctly, she'll rip.

 

Sounds good, I'm going to make one change at a time and keep track of things. For the longest time I ran my exact set up but with the snorkel in, my MPG was like 46-48 and I was kind of pissed. I knew it was really fat because I never had to use the choke even on cold winter mornings (winter my ***, that's like 40 degrees around here) non the less I pulled the snorkel and I started to need the choke some times. Also my MPG went up to 56ish again and I can tell it just runs better all around. The best part was it still runs great up to 8k feet in the Sierras. I'm hoping to benefit from this mod and keep the same drive ability.

I'm not sure if I'm imagining things but it seems like the engine runs a bit warmer so I'm pretty certain it's lean. I'm feeling ambitious so I'm going to go adjust the needle now and rip that ****.

 

You are smart to go one change at a time. The needle is fairly easy, just pop the tank off and you are there. Try one clip position for starters.

 

Ok, I'm on the 4th from the top now on the needle. A nice smooth roll on delivers great response and power, a snap to WOT kind of sucks, especially below 5.5-6k.

I left a light and took off quick, soon as I got the bike rolling I went from the friction zone to fully engaged abruptly and hammered it. I did it in a way to test the bike more than be fast. It definitely bogged and did a hiccup. With all my riding the last 8,100 miles and random crap I've tried, the bike has never done that. Seems to me it's still lean. Anyway I'll sleep on it and maybe fiddle with it more tomorrow.

 

From what Kawasaki claims and what you and Marcelino shows, it doesn't drop much. Kaw claims at around 8200, without looking Marcelino had around 8000, yours is close to the same, so not really a big drop. Plus the overrun doesn't drop off too much worse than stock from what I've been able to see.

As you acknowledge - a good low cost mod.

 

Well, after doing some thinking I'm starting to wonder if maybe the bike is rich. After moving the C clip down to the 4th notch it bogs a pinch more off the line. Also, the bike didn't need any choke this morning to start or idle. I'm sure disabling the ACR had an effect on its ability to fire faster because the compression but my bike has always needed a split second of choke to fire after it's sat over night or more than a few hours.

 

I had to move the clip to the second position from the top ( moving needle down/leaner) to stop the bog. With lid off, UNI and 132 main its the smoothest i can get it and best gas mileage. I can roll on or hit it hard and no hesitiation or bog.

 

I hope that works for me.

With the air lid on, snorkel removed, 128 DJ jet and 4th clip down it boggs bad but runs great higher up.

With the clip on the 2nd down and air lid removed there is no bog but the power falls off above 5-6k. Also surges at 65 mpg at steady throttle.

2nd clip down air lid on, no bog, slightly better power but I'm not impressed and it still has a small surge under light load above 35 mph.

Tomorrow, I'm going to try 132 main, 2nd clip down and no air lid. See how she goes.

My buddy has a 12' with the same mods as mine, it's literally a carbon copy of my bike down to the hand guards and USB charger but his is red not green. Anyway, I rode it for comparison...it rides friggn good. Way smooth power band, pulls good and just nice. No cam mod on his bike.

Hmm...I'm hoping to get this dialed in for a unfair advantage on my junk. Maybe I'll have an epiphany after I pass out in 15 minutes!

 

So are u sure its a surge?? I thought mine was too but its something else I`m feeling. If I coast down a hill I can still feel it with the clutch in. Also on hard acceleration.
Just saying.it may not actually be a mixture issue
