oky doky, here's a question for your clever types. . .

on the RHS (as you sit on the bike) of the cylinder, about the 2nd fin down there is a hole..

checked it on my baggy and it goes about 3 inches deep and there is no thread.. .

occasionally near that fin there are rusty water marks evident. .

any ideas what its for ?

Cheers

I think it may be a drain for water that gets thrown up into the spark plug hole, but I could be wrong.

yes my rt125 has one also

every time you change the spark plug make sure it is clean and water
can flow out so that some day the bike does not stall out
because the sparkplug does not know how to work and swim at the same time......

Ahhh of course!
I've often wondered what it was for...

that'd make sense. . .

Cheers !
