2004 KTM SX 125 Questions & Answers
How much oil per gallon of gas
A fuel mix of 32 to 1 is the standard. That means 4 ounces of oil to one gallon of gas. Be sure to use two stroke engine oil in the gas. DO NOT use motor oil. 10w40 motor oil is for the gearbox.
A top rating would be nice. Thanks!
I got my piston in
Thanks for contacting FixYa. I was reviewing some of the older un-answered questions trying to ensure your issue has been resolved.
You should be able to resolve this issure by just removing the top end. You will have to remove the tank, the pipe, disconnect the carb, any water hoses, and possibly the radiator. If there is no damage to the connecting rod you be able to thoroughly clean the crankcase withough removing the engine. If you have damage to the top rod end you will have to pull the engine and split the case to replace the connecting rod.

.020 is 20 thousand over stock
How do i check the oil level on sx125 03
On the right side of the engine, just to the rear of the cluch cover and just ahead of the rear brake lever spring...remove weep bolt(will have a soft metal sealing washer, usually 10mm bolt head). When full, oil should just trickle out the bolt hole with bike held upright.
I dont know how to check the transmission fluid
most transmission fluids on motorcycles are topped up until it is full if it has a side filling hole (stars to run out of side) with motorcycle level (like on ceneterstand). a top filling hole will have a dipstick. basically you want the gearshafts half submerged in oil.
Has it got powerbrands
There are no such thing as powerbrands.
It does have a power valve system. It is not uncomon for these to be incorrectly adjusted after you do a top end job. My best guess is that this is the case. The owner's manual covers how this can be adjusted.
