Need to buy 21" inner tube, metal center stem..Looking on e-bay and seen some.Some was tr4,tr6.Whats tr4 and tr6 stand for?

it's the shape of the base where the schrader valve attaches to the tube, TR6 is oval while the TR4 is round.

I'd use the TR6 but would be interested to know what CraigArizona85248 uses.

Be sure you get a quality tube. I have heard there is some cheap tubes out there.

Going off on a tangent, sorry.
The last time I but new tubes in my daughter's bike I bought puncture resistant (and supposedly self sealing) inner tubes. They were expensive but with her away at school, and away from the old man's air compressor, they are really holding up well. Does anything like that exist for motorcycle tubes?

Dunlop makes a great quality tube and that is what I would use.

German made Moose tubes.
I run them in my off road stuff

very heavy duty.

only if they  make a street version.  on my dirt ones they are very thick to resist compression blow outs and small punctures.
they would get too hot on a pavement application.

but short answer  is yeah,   some one probably does.
