1999 300mxc

[phatbulldog]

I bought a used 99 KTM 300mxc about 3 months ago. My question is I haven't changed the trans oil becuause I don't know how much oil and what kind I should use. Also how often? mostly ride my Cannondale 4wheeler so I don't ride my bike too often. I broke my left fibula on it about 2 months ago. Not off to a good start with that thing. Any help will be appreciated. thanks

Use Any good oil without friction additives : 10w-40 or ATF.

I run Type F ATF in my 99 and change it every 4-6 rides or every 2-3 hours of racing.

I think you should stick to a motorcycle gear box lube like Bel-Ray GearSaver or Silkolene Light Gear Oil. 75-80wt gear oil will work great. My 200 uses 700ml, but you should call the local dealer, the will know for sure.

I like Mobil-1 synthetic, 20w-50. My 300 takes about 800ml.

There's a fill bolt that you remove on the side of the case. Pull it out, and start adding oil until the oil starts flowing out of the bolt hole. I think it's around 800ml. I recommend a synthetic motorcycle specific oil. Personally I use Dumonde Tech. It's available at www.hgnr.com Any of the 10w-40 stuff you find at a motorycle shop will work great as well.

Be careful when tightening up the oil level check bolt they tend to strip out very easily. I measure out 800ml and then funnel it in. I use Bel Ray Gearsaver 80w and change it about every 100-150 miles.
Good luck

use 28 ounces of oil. a motorcycle 2 stroke specific transmission oil ( i use Champion Racing Lubricants LV 80wt. You can also use a straight weight SAE 30wt. non-detergent car oil.
