SOURCE: CONVERT A YZ 250 INTO A WR 250
The YZ is a dirt bike as is. The WR is a street bike and has more accessories on it.

SOURCE: 2003 YZ 250 Oil Change
Use 10w40 in the gearbox. Get the oil from your Yamaha dealer along with any filter your bike may need. Some bikes use an oil change as the "filter". To drain oil, get the engine warmed up and turn it off. Put a pan under the gearbox and remove the oil drain plug. Replace the oil plug when the flow becomes a slow drip. Change oil in late spring, the middle of summer and in early fall. Remember to lube the chain and adjust it when needed. Lubricate the cables with liquid graphite. Lastly, install a stock spark plug. Now go for a ride.
Please rate this solution as a "FixYa" if I have answered your questions. Thanks!

You know aluminum can be welded very successfully now, so best bet is to remove that case and take it in to a good welder..You can ry the quick fix (JB Weld) is what i recommend, but success is rare !....good luck to you my friend...Tim

hi buddy right start with warming the bike up then underneith engine will find the oil plug unscrew it then drop the oil out into a pan once drained put the plug back in and tighten it also it is recommended you change the oil filter every oil change as dirt in the filter will turn the oil black then you unscrew filler cap on side and fill with oil i recommend using silkolene pro 4 then fill it until the oil is 1/2-3/4 full on the sight glass thanks bud i hope this helped
