Welp it’s official im going into uncharted waters and will be rocking a 24’ 300sx paired with my cmx120.. still going to keep the trusty 15 fe501 but i think this 300 from what i hear will be a blast to ride. So here is what im thinking for mods..
Tsp ecu or erm
High comp head
Xrt heat exchanger
131 deg tstat
Swapping my heated bars over
Selkirk intake
Pipe?? Not sure what yet.
Make my own engine blanket
Any other stuff i might be missing besides little things like pegs,hand guards, temp gauges etc.??.
Do these not come with a t-stat? I thought all the 2 strokes from ktm had a 158* stat stock? If so I highly recommend staying around 160* so it keeps the ecm, which now controls the powervalve, happy. Otherwise you'll be running rich just like the 4 strokes when they don't get up to temp.
I really liked my pro circuit platinum with shorty. I know everybody will argue but I say ceramic coat or wrap the pipe. We noticed a big difference between my buddies 300 performance vs mine with the wrapped pipe. His would spitter and sputter randomly until he wrapped his, then he was clean all the way through.
The head will take a m6x1.0 temp sensor in the coolant bleed screw hole to monitor temps.
I ran a c3 intake but removed my stock air box and made a "tent airbox" with most of my silencer inside my "tent airbox" for heat. Kept my filter clean even on deep blower days. I just used heat resistant vinyl.
Definitely run a good blanket.
Buy a stock xc tank so you get that extra 45 oz of fuel. Ha
Our group have been on 300 2 strokes since 2019 and love them. I went to a 450 and 3" and hate it. Wishing I had a 300sx and 2.5" 120 or 129.
