Just picked up a 10hr 22 150SX…. Can anyone confirm, looks like it came stock with the S4 nozzle, not the S7 the 125 comes with?
Yes, should be the S-4 in there. Only way to know for sure is t to pull it out and check the stamp.
6hr round trip yesterday for this 22 150 with 10hrs on meter….stoked….already tearing into it and ordering parts😂
Thanks… I will be pulling carb off this afternoon…I”m going straight to the known jetting in this thread…I will cut slide myself, just need to order the correct needle..going to stay with the Aer forks, need to at least get a spring for rear shock…3.9 not going to work for my 190lbs. Unfortunately I gave away all my stock 350 springs from that generation…chassis going to get a greasing while I”m at it….

We”ll what do you know….
I would go with a 45Nm spring for 190 lbs with no gear. I am running a 42 on my 150 and at 185 I am kind of right at the point where I could go with a 45 if I was any heavier.
The specs on page 1 are where I would start on your 150. They are pretty much exactly what I am running in my 150 at the moment. As for the 2022 bog, I ended up needing to go to xx-75 needles to tune that out. Keep that in mind if the xx-74 needle gives you the bog. The specs were developed using 40:1.
Also, double check that your float is 8 - 9mm while you are in there.
Thanks for your input…I planned on running 40:1, so we”ll see how the jetting works for me..just ordered everything I needed for the carb…debating on picking up a used traxx shock, they are priced pretty good being the older chassis…I have no problems with the stock shocks once the proper spring installed…what gearing are you running? I read 14-50 helps the broaden the shift points?…
My bike is a TC125 that I put a 150 kit on. I am still running the stock 13/51 gearing from the 125. I know guys talk about the 150 having the torque to pull taller gearing, but I don't really see it. But I haven't tried to be sure so....
Maybe I should ride it and decide…the stock gearing on this bike is 13-48…I have an MxA mag that states the stock gearing is ok but most preferred the 14-50 as it’s slightly taller…
With the 13/51 I am getting really good 2nd gear starts, can carry 3rd in corners where momentum is up, and drop to 2nd for tight inside ruts, which all seems about right to me. Most jumps are 4th gear with some bigger ones or longer stretches to the corner being 5th. If I was running 13/48 or 14/50 I imagine I might need 1st on starts or 2nd with a lot of clutch slip and then I'd be spending a lot of time on the track trying to stretch out 2nd and 3rd with lots of clutch. For reference, my bike has like 85 hrs and is still on the original clutch! Kinda crazy for a 125/150, so I guess you could say I am riding with a style that is more about lots of shifting and being in the correct gear than it is about hammering the clutch to stretch out taller gearing. So it depends on your track types and riding style preference. I also stayed with the stock 14/49 on my 250 when I converted it to a 300 and some guys say the same thing about running taller gearing on those.
Don't waste your money on a Trax. I had it and a 22 350 and I sold the bike with the trax and put the 22 shock on my 18 250 2 stroke because it was just as good if not better. For this chassis a ride engineering link and the sag set to 103 is the way to go. I have an extra one I'd sell if you're interested. Its been in my gear bag for a few years so it will need the bearings and stuff from your stock one. I noticed it calmed down the rear swap into turns with a lot of braking bumps and made corner exit with sharp square edge bumps not as painful. On the gearing I liked the stock better, the MXA gearing was shift city and having to remember what gear you're in after down shifting 47 times into a turn makes it hard to ride fast lap to lap when you start getting tired.
Ok, appreciate your input…I will leave stock for first few rides & see how it feels… I prefer not to have to use first gear also….
Thanks for input AJ…I never have had a reason to buy the Traxx shock, I have been on KTM”s for 10 years..usually Factory Connection does my suspension…I”m getting old and like to spend $😂…I figure the valving is on the lite side for my 185-190lbs ..I will replace the shock spring with a 45kg and see how it feels…thank for the linkage offer….I will let you know….
Update:
So got the pro circuit platinum pipe on with the r304 shorty I had from earlier. Took a few kicks tk start (probably needs air screw adjusted) and fired up. Warmed the bike up and took it for a few pulls. I definitely did notice some more topend pulling, before when the bike would overev it would sort of push you forward a bit as the power fell off quick. Now I dont feel that as much and it just feels better up top. Running the exact same jetting as stock, 510 main, clip 2 42-74 needle, 32.5 pilot, air screw 2 ish turns. Might just experiment with changing the main to see if there is any performance left on the table, but im happy with the pipe for sure. I think the needle is good as no bogging or stuttering and pulls clean, but I could be wrong. Also thats a extremely clean bike sandman, only wished my frame and motor looked that good haha I spent a lot of elbow grease cleaning it up.
Nice..l I just ordered the PC pipe & silencer few days ago…spent the last few days chipping away at prepping bike…chassis now fully greased, my bend of bars, carb settings done, new plug, I had some of this generation plastics with my # on them…I had the shock spring also…thought I gave it away….Also put my Aer forks from a 24 350sfx on, figured valving stiffer…just waiting on the pipe…I may flip the rear tire for a fresh edge…this generation is much easier to work on than the newer bikes…going to leave gearing stock for first few rides & see how it feels…. Likely go with a 14 front, as I agree with AJ on the chain torque effects on rear suspension…. Whats everyone using for gearbox oil? I probably go with Rotella T6, I use that in everything else…
When I had my 22 350 and talked to Powerband about the suspension because I sent my cone valves to him for a refresh and maybe a revalve. I told him I hated the AER forks on the 350 because of no front feel or traction, but when I put them on my 250sx they were just as good if not better than the cone valves and he told me that for some reason KTM has different valving for the 350 than the rest of the SXF line. Now I'm not sure about the 24+ stuff, but maybe they did that with those as well.
Gearbox oil I use Motul Transoil Expert 10W-40 and now have 200 hours on the bike with the stock clutch still.
I have not played with the Aer forks since 2022 on my 125…I”ll give these a try out…figured the weight savings was worth another try…My KtM clutches have also been bulletproof…and I”m a habitual clutch abuser…😂
Bel ray gear saver 80w but recently its out of stock , so i switch to motul trans oil expert 10w40. Whats your power valve setting? . im on oem spring 1 turns in but i didnt notice any change, i was 1.75 turns. Soon i will try the red spring , would like to feel the power band hit a little sooner.
Pit Row
Just finished, fired up first kick…the 5.4 shock springs is too stiff, can’t get correct sag #”s… I”ll ride it a few times to check the jetting and gearing, then send shock off to FC for a proper setup….
