My son has a KTM 65 I recently replaced the oil pan bolt and oil, just wondering why it now after 10min of riding it runs not right real chuggy then conked out and has oil kinda coming from the exhaust? Is it too much oil in the oil tank/pan? Or too much oil in the fuel?

SOURCE: Removal of oil pan?

The car has three mounts in a triangle configuration. The front trans mount, the passenger side motor mount and the rear motor mount. I do not know if anyone has ever successfully raised the engine to slide the pan out, but remember, if you do this, the pan goes back on with anaerobic gasket maker on it, so make sure you can slide it out with grating on the underside of the block. If you can't, then it will likely be impossible to get back in place without smearing the gasket maker all over and making a heck of a mess. The commonly accepted way to remove the pan is to remove the two front subframe bolts and allow the subframe to drop enough to get the clearance you require. The bolts are 18 mm heads and are really torqued on there so you will need a serious breaker bar and cheater bar to go with it. USE SOLID JACKSTANDS or BETTER YET, RAMPS to do this. The force you will need to apply can take the car right off a single jack.

Check temp control sending unit and thermostat.

I HAVENT CRANKED MY BIKE IN ABOUT A YEAR, IT NOW WONT START AND I THINK ITS BAD GAS HOW DO I DRAIN THE GAS AND CLEAN THE FUEL SYSTEM

Make sure the choke is fully disengaged while riding. Is it two stroke? If so, make sure fuel/oil mixture is not too rich. If four stroke, try a colder plug. If four stroke, make sure valves are adjusted properly.

Ok, a two stroke engine basicly needs 3 things to run: fuel, compression and ignition.

First, check that the fuelline, fuelfilter, or fueltap is not blocked. If the fuelflow is alright, check that the compression is fine. try kicking the kickstarter a few time: the should be a certain resistance.If the compression is wrong try changing the headgasket. If it is alright, check the ignition. This is done by taking the sparkplug out at placing it on the frame, when you kick the kickstarter a spark should jump from the sparkplug to the frame.

But my guess would be that you have a partly blocked fuelsystem.
