Title: follow up jertting question for foxx4b.
Post by: b4himdude on August 10, 2015, 04:29:56 PM
the bike is running great now that i put a new bottom end in it. i have a feeling our (well your recommendations) and my jetting is d**n close. what i see on a brand new plug that i ran pretty hard for 3  15  minute rides is like a honey golden coating on the base of the plug that you can scratch off. is that a good or bad indication. youll tell me to plug chop and i will. but dies that sound close?

it doesn't look bad...I would've liked to of seen a much closer pic...but I'm not seeing much black oily residue, or a bright white insulator, which is good...
what is your current jetting?...and how many turns out is your air screw?

*edit*
you're running the N82R needle if I remember correctly, right?

yep an n82r in the 2nd clip with the air screw about 2 1/2 turns out. ill see if the other pic is closer up and ill post it. the bike is as responsive as the throttle turns. no lag or any thing. the pipe seems to get warmer on my leg than i remembered. but i dont know that it means anything. let me post that other pic.

go up one size richer on the pilot, that should get your air screw closer to 1 1/2 out.
it's on the leaner side, that's why you're feeling the heat on your leg more.
what size main jet are you running?

because it was 10mins til 5am this morning and I was in my normal rush, I forgot to add.....run this if you're not already!...it makes a big difference!

make sure you're running no lower than a 168 Main also...things tend to get rather "warm" if you're running wide open a lot with anything less than a 168....a 170 would be better if you're really planning on running wide open a lot....this is where plug chops really come into play...and you may even end up at a 172...try a 168 to start. :wink:

ok purple ice where do i find it? im gonna go yank my carb real quick and take a look at the main just to be sure of what im running. i think that it is a 168. so if im running a 52 pilot youre saying put the 55 in. (and / or )go 1 notch richer on the jet needle?

my local Kawie dealer had the Purple Ice....but you can get it on e-bay, amazon, etc, if your Kawie dealer doesn't carry it...

see how it runs at low speeds with the 55 pilot and set the air screw(it should end up either side of 1 3/4 turns out)...if it doesn't start loading up or start feeling sluggish at really slow speeds, leave it with the 55.
leave the needle position where it is.
let me know what your main is.

ok presently ove got the 168 in main. i do have a 170. should i put the 170 main and the 55 pilot in at the same time.? right now since its open.
?

Post by: Foxx4Beaver on August 17, 2015, 12:32:52 PM
no...just put in the 55 pilot, set the air screw, then do some slow trails or just putt around and see if it loads up any.
If it still seems like it's running pretty crisp...leave it.
you should notice that it doesn't/won't get quite as warm at slow speeds with the 55 also.

good thats all ive done so far. i was waiting to see what you had to say before continuing. thanks a lot. and as always ill keep you posted. thanks again.

just so you know, it's best to make only one change at a time with jetting...otherwise you won't know which change made the difference if you do more than one change at a time...and it could get costly. :x  
yup, let me know how it does...you're welcome.

kinda figured that about the one change at a time stuff. like you said why chase your tail. i was just thinking maybe you had some thoughts. i guess u did . ine change at a time. anyway.... i took it for a testy ran her slow for a bit after blowing out the original chunk that i think all 2 strokes have. and it seemed to not be as responsive at first. i mean it was there after a slight hiccup . then it seemed to get better as i played for a few. but when i got home i looked down at my air box and the dampers on it were fully closed./ so i dont know what kind of performance loss closing the dampers when you wash it and forgetting to open  them before you ride has . but i imagine she wasnt getting a full breath of fresh air when i would lay into her. what say you. other than duh?

Post by: Foxx4Beaver on August 17, 2015, 02:02:53 PM
I had a feeling it would "hiccup" a bit with the 55...soooo, throw the 52 back in, and put in the 170 main...do a couple plug chops just to be sure it's not too lean...but I'm thinking it'll be good/safe...and enjoy!

I never run the vents on the air box "open"....I find running them open just dirties up the air filter very fast!

thats the combo. its right on the pipe.....52 pilot, 170 main 1 3/4 turns out on the air screw. :-D
