got the magnetic plug in today
hopefully it fits

 

i have the same one, but in steel...

 

Hmmm... I think I would rather loose the threads on the drain plug than the threads on the case. Maybe?

 

all the ones I have on my bikes are aluminum
and ive never stripped anything in all my years

 

If you haven't stripped anything in all your years, you need to buy a lottery ticket...now.

But seriously, you only need to work at a dealership or somewhere else to see the relatively constant parade of motorcycles with stripped fastener threads of all kinds that come into shops for helicoils or component replacement. People do this all the time, so it's better to buffer against the ham-handedness of home mechanics where you can.

 

ive never stripped a spark plug either

I read about that happening so many times, I cant even see how that happens

 

faulty torque wrench is one common way....lot of people don't understand that it's a plug, not a fastener and strip it...

 

Most are young guys working on hot motors. I've noticed the trend.

I like to avoid the dissimilar metal issue when possible, so I'd go with the aluminum plug in an aluminum case. You may never have an issue since the threads are usually coated in oil, but I'm paranoid and have issues.

 

I've often used nickel anti-seize on troublesome plugs. Just a little doesn't seem to have any adverse affect on ignition and it makes them much easier to get out. I wouldn't be surprised if using too much could cause issues though.

 

right, so isnt my engine aluminum
because I got the aluminum magnetic drain plug
