i just bought a new KTM 150 SX after riding Japanese bikes for 44 years. i'm great at jetting but can always use advise. i need some input on suspension,tools, oil ratios(I hear you mix it 60/1) and any other items to watch for. I race 60 Masters class. Thanks for any help.Just got off a 2011 YZ125.

What year did you get? I've had a 2016 for a few years and just bought a 19 yesterday. No big problems as of yet. Great bike, you'll have a lot of fun!

I don't buy the 60:1 stuff. I ran 36:1 Motul in the 16 and it worked just fine. Did a top end at 22 hours or so and the piston still looked great. Going to run the VP T2 (premixed 40:1) in the new one. Hit up Brian at N2D (flipside) for suspension if you're looking for a revalve and proper setup, he's got it all sorted.

Great bike, congrats.  I got a used 2017 sx 150 about 1 1/2 years ago.   It had a Bill's pipe and silencer on it.  I put on a Lectron Carb, V-FORCE 4 reed set up and added a 8 oz fly wheel. 

I did the 60/1 mix with Motul no problems.  The previous owner ran   Did the first rebuild at 30 hrs everything look great.  I trying around a 40/1 Motul premix now to see how this next rebuild goes, mainly because I read while the piston, rings and cylinder may look fine the lower end might be taking a beating.

Bike runs great absolutely no hesitation running through the power band.  Put the Lectron on over a year ago and haven't touched it.  It is exactly the same as when it came out of the box.  Got the V-FORCE 4 reed set up because the stock reed set up didn't close completely.  Seems to work ok.   Put the fly wheel on because i planned to do some GPs and maybe some other offroad stuff.  It works great don't even notice it's there except the power is extremely smooth for a small 2 smoker.  Race MX most of the time and I think it really helps keeping traction and preventing stalling.  Love the bike and haven't done anything to the suspension except play with the all the settings and that seems to keep it handling just fine.

If I keep this bike much longer I may get a Recluse clutch for it.  Had the original Recluse on my 04 CRF 250 and really liked how it worked.  If they come out with electric start on a sx 150 I'd go for that.  Maybe get the KTM XC-W 150 that has it already and do the same mods to it that is on my sx150 now.  Only do that if they never do the electric start to the sx 150.

You can't beat a sub 200 lb bike with 40-45 hp.

Thanks for the input. I've been running my YZ's on VP T-2 and have never any issues. I'm going to try it on my 2018 150SX. Can I use run Maxima MTL 80wt tranny oil in my KTM? Thanks for any advice

The Maxima oil will be fine, that's what I run.

If it's a 2017 or newer, you will need the fork air pump and check the pressures often.
You will also need a torx wrench (lock on grips, subframe, sprocket bolts) and a 13 mm box wrench (rim lock, chain adjusters). A lot of these tools should have come with the bike.

Thanks for all your advice. Working on small jetting issues.I just put a V-Force 4 reed kit and a 49t rear sprocket. Seems to run great.
