well since you said that I went and did some research and what I found out was, surprisingly enough, there are two versions of the early silver SOHC 750 comstars - tube and tubeless. Although they were designed to be tubeless some of the early ones were shipped with tubes in the tires. If they have a metal retaining nut on the valve stem they are tubed. Some of the wheels were also stamped tubeless and some were not according to what I can dig up.

The Comstar was Honda's replacement for the tension spoked wheel. Whilst spoked wheels offered a degree of flexibility to help absorb road imperfections, they also required periodic maintenance to ensure correct spoke tension and required the fitment of an inner tube. Honda claimed the Comstar design combined the strength of a cast wheel but allowed a predetermined level of radial flex like spoked wheels.[7]:27 Comstar wheels also allowed the fitment of tubeless tyres which, like other alloy wheels,[8] helped to reduce unsprung mass,[9] although not all models fitted with Comstars had tubeless tyres....... Honda first fitted Comstars to its road going motorcycles in 1977 on models such as the CB400T Dream, CB750F2 and the later flagship CBX1000.
