I have read plenty of forums on this exact topic and have gathered some info; now I just a little more help. bike is a 2001 wr426f and i strippped the oil drain plug under the crankcase. I either want to drill out the stripped threads, re tap, and install a larger drain plug OR go the timesert way. First I'd like to know which you folks think is better. I would like to have metal threads as in the timesert so i hopefully dont do this again (I'll also be buying a torque wrench). I do not have the expertise to split the case. I can take it to a mechanic, but if they are not going to split the case either, I'd rather do my own work. If i install a timesert what size kit would be necessary? I do not know the sixe of the current hole or bolt but I assume they are factory size. How can I flush the engine with oil after doing the job? Oil does not enter the crankcase on my motorbike until it is started (this is how dry sump engines operate if I undersdtand correctly). Any advice or information is greatly appreciated.
