Tube Question
« on: March 08, 2008, 07:47:36 am »
so when putting a 130/90/18 tire on a comstar rim, what size tube should I be looking for?  I wasnt sure if stock size will work.

An 18 inch one, but seriously if it was a tubeless comstar rim you will need a special nut, originaly sold by Honda, that fills in the extra size hols

If you can figure out the dimensions, PM me and I can make some on my lathe.

Get a bolt in valve stem, they come in various diameters then you can go tubeless
