boolzi Added a reply to 125/150/250/300 KTM/HUS/GG jetting thread
10/27/2024 2:05pm I went with the 500 main and 32.5 pilot, the 35 was too rich I guess. I started with power valve at 1.75, went to 2. I will mess with it. Bike runs better than it has with stock jetting or the keihin 38 with jd jetting. I just don’t think I like ktm 250’s. Last one I had was...

10/26/2024 3:36pm Your 1 3/4 in from flush? Or completely out? 1 3/4 isn’t far from oem setting I think. as fgr01 stated he went with 5.75 recipe for the richer setting…isn’t the 5.5 richer? Did you do the 500 and 43-75(2) with the 5.5?

10/26/2024 10:00am Put in the 5.5 slide recipe this morning. Test drove and it’s got more power for sure, better pull. Sounds good, pipe bang/decel surge is minimal but I do like to have an idle. My first impressions are that this is a very “hot” jetting, so hopefully it’s not too lean. 800’ 60f-ish 5.5 42-75(2) 32.5(might try 35) 490(might try...

10/13/2024 5:45am I dont know man, i took the mikuni off and got the keihin 38 with jd jetting, i went up and down and couldnt get it right. I replaced the mikuni mid body gasket, set float height to about 8.5(it was like 11) and drilled the drain cap and splash guard and it seems its better with 43-75(2), 27.5, and...

10/12/2024 5:52pm I have a 2019 250 xc and am interested in this jetting. I can get the kawi slides at my local Rocky Mountain, i would like to do the jetting with the 5.7 slide, but intend to eventually put a 300 kit and the 300 jetting you have uses the 5.5 slide. Question is, how much difference in the 2...

9/27/2024 8:56am Thanks. Higher compression and better dome burn better not leaving combustible exhaust left over.

9/27/2024 8:23am So your saying the head, which I assume tighten squish up and raised compression took care of the pipe bang/decel surge? Cause that’s where I’m leaning.

9/27/2024 8:21am From everything I’ve gathered is excess unburnt fuel/gasses in the pipe. The pipes actually feed fuel back into the chamber and if enough is there it will “ring ding” with a slightly elevated rpm til it’s burnt up. Here in this vid you hear me rev it, then as it goes to idle it almost sounds like I barely open...

9/26/2024 4:47pm And for the record, the tpi was good, decently great running bike with no jetting issues. The 2023 300 tbi was my favorite dirtbike I’ve ever owned. The motor was incredible, more than incredible. It was a rocket, or it was a moped. Just depended on what you wanted at the time. Unfortunately a bog I could not get rid...

9/26/2024 4:42pm No, the 2020 300xc was tpi, first year for it. I think ktm started putting the “b” team on production 2t’s in 2018ish and the “a” team was on the new fuel injected motor. 2017-2019 carbed ktms dominate the jetting/pipe bang internet search results. The xcw was fuel injected for 2019 fyi. The sx didn’t go FI until 2023.

9/26/2024 3:59pm So far new carb and new reeds, up and down with jetting. No change in pipe bang. My intention when I bought this was to put a 300 kit on it, but would hate to deal with this after a $1200 300 kit, cause this engine sucks. No excitement, terrible sound/tone, and this crappy pipe bang/decel pop surge. I’ve had...
boolzi Started a new thread Pipe bang/decel surge… 2019 250xc
9/26/2024 4:12am I picked up a 2019 250xc with only 7hr on it. Has this bad pipe bang/decel surge. I put a keihin 38 and rad valves and went up and down on jetting. It’s very aggrevating. I don’t remember my early 2000 250’s having this. My 2020 and 2023 300xc’s didnt have it. Currently I’m on a 2024 yz 250 and...

8/2/2024 9:40am I just put a fatty and shorty on my 2024 yz250 with stock jetting, ran the same. Rich. I threw the jd jet kit in and it took the on/off switch away and runs great. I guess what I’m saying is the pipe/silencer makes little difference.

Mine were damaged right where the wires going to the throttle body splice into the main harness

7/6/2024 5:24am I absolutely know the exact spot you’re talking of well, very well. When it was newer i put a peice of foam there and re-zip tied it. But as i still couldnt get rid of my bog issue last week i completely cut my harness open. It’s all in great shape. But that spot where your talking about does look...

7/6/2024 5:11am I’m in on this. Do ride track?
Is the ec the xc-w version, cause the xc and sx seem to be the ones effected by the random bogs. The less power, or something of the enduro models must have something to do with it cause you rarely see those models on the facebook groups with the random bog. I also understand that most enduro models are just...
