What did you do to your Vintage bike today?

Cool! I don't know much about those bikes but thats a lot of valves to adjust!

Found an engine diagram online. Looks like two cam chains and some kind of primary chain too.

how cool is that? :thumbup

looks like the two-chain cam-drive allows the head to be an inch narrower on the intake side than it would be with a single cam-chain?

trying to figure out how the smaller-appearing sprockets driving the intake cam stay in time with the bigger exhaust cam sprockets ...?

edit: guess the exhaust sprocket does the half step down and then a smaller set of sprockets just spins the cams together at the same speed ...? (cams spin at 1/2 crank speed in 4T?)

can't say I recall another production motorcycle with the CBX's two chain set-up ...
doesn't your Dream 50 have an unusual cam-drive, also ...? :dunno

fun stuff! god bless Honda ... :ride
