Hi,
I have a 1984 Suzuki DT50. I need to replace the gear case oil drain screw. However, I need to make my own as the official suzuki screw is not long enough to reach the good thread inside the hole. I have a machinist friend who is going to help make the screw but I need to know what metal to make it out of?

Thanks in advance.

use 316 stainless steel or 304
304 is cheaper but a little bit of 316 will not be that dear, or you could probably put a recoil thread in and use your old plug ?

There seems to be a little confusion here. The motor is made out of aluminum. The screw is SS.

Thanks James R.

I thought the screw would be the same metal as the motor. But easier if it is not as I can just get the right length SS screw and all should be good.

Finding an M10 fine threaded SS screw is a nightmare though. I have to wait 2 months to get it delivered here in Australia.
