on the lower right side of the crankcase. Large plug with a spring and strainer behind it.
your problem maybe the sensor
At the bottom of each fork there is a hex head bolt, metric I think # 8 Be careful not to strip it.
The oil plug is under the oil filter ...straight bolt ..14 mill..
There is no oil filter.. The drain plug is on the left side of the bike.
Pull the oil plug located at the base of the oil pan.

lowest possible point on the engine
There is a oil sight low on the engine on the throttle side
Well, I have an '04 TTR225 and I'm sure they're quite similar. On the lower left side of the engine, directly behind the gear shifter, there will be the oil plug. Loosen it with a 19mm wratchet. The oil will immediately begin to pout out. Contain it somehow with a bucket or whatever is available and dispose of it accordingly. Then reinsert the plug and fill it with the correct amount of oil. The entry wat for the oil will be directly above the "YAMAHA" logo on the right side of the engine casing. Pop that off and fill with the correct amount of oil. And there ya go(:
there should be a dip stick on the bottom of your filler plug.
you will need to pull the drain plug, then take off the oil filter, then replace the oil plug and the new filter, finally put your new oil in.
there should be a sight glass on the right side of the motor
