what did you just say WR?

turtlemann14 · 02-21-2008, 02:21 PM

is there any way you can get the ring thickness and such?

like you wouldn't happen to have a micrometer sitting around to measure it would you?
or are just going to try to find one that does the job

gscx · 02-21-2008, 03:17 PM

i need a new piston to because it has a big chip on the side of it, so if i can get a piston i can get rings, what about a PW50 piston? oh and WR there was a yz50 way back in the day, and those things were pretty fast, mine is fast but it was probly faster when it was new

tjscott2012 · 02-21-2008, 03:43 PM

is it yours? and howd you get it so cheap? the yz50 is moderately rare.

turtlemann14 · 02-21-2008, 05:30 PM

so you know the bore of the piston?

tigmaster · 02-21-2008, 05:52 PM

You can take it to a machine shop and have them mic the bore. Then look up other bikes with that bore or ones that could be over-bored to fit. But the odds of that is even rare but then you have to match the skirt style and size and the wrist pin diameter.

turtlemann14 · 02-21-2008, 06:04 PM

i wonder what the chances of a newer 50cc bike having the same bore and skirt is?

tigmaster · 02-21-2008, 06:05 PM

Not very high.
