well the topic pretty much describes the problem but anyways... I have an 05 450r and after 15 or so oil changes the drain plug is dripping, now I understand I prob over tightened it once or twice but what can I do.........Do I need to re tap the threads and choose a larger plug or can I add a washer.... I am tired os a little drip drip drip on my garage floor..... Now one thing I highly doubt but anyone think this might be covered by the 4yr warranty?? (-:

 

I would try a new aluminum crush washer first and then torquing it to you specifications in your owners manuel. You would be surprised how little torque is needed to tighten the drain bolt.

 

Start with a new washer.....

 

some drain plugs have a o-ring, could be damaged

 

Ditto

 

I had the same problem with mine. I just wrapped a few turns of plumbers teflon tape to the bolt and problem gone. Plus the teflon tape is cheap and you can get it just about anywhere. Just rewrap it every time you change the oil.

 

If the other suggestions do not work...

I stripped out the drain plug on my 250sx a while back, and the threads were too damaged to repair. For a temporary fix, I screwed a piece of heater hose (o.d. just about the same as the i.d. of the drain hole) onto a smaller screw that fit tightly inside the hose, and used that contraption to plug up the hole. You would be surprised how well that worked, though it sounds like something only an idiot would do.

For the permanent fix, I bought one of the self-tapping drain plugs one size larger than stock. Using the stock plug, I "stripped out" the rest of the threads to clean up the drain hole. Then I stood the bike up on its grab bar and slowly torqued the new plug into the hole, working hard to keep it perpendicular to the bottom of the engine.

Back it out often and clean off any metal shavings, and keep the new plug oiled up so it can cut the new threads cleanly. I've had no leaks on the bike since replacing my plug, and I've yet to strip another since I bought the torque wrench...
