okay
So you think OS. 21tm, mTOR is better than TRX3.3?
you know tell me, if OS. 21Tm works well to how many liters of fuel?
3.3 TRX damaging the bearings 6 to 8 liters of fuel. They say that this is normal in this engine.
some riders, I say to that used more than 30 liters of fuel on OS .21Tm and bearings are perfect.
is this true?
