New to forum, not new to cb750's...question on 4into4 exhausts
« on: December 16, 2019, 02:19:08 PM »
Hi -

Does anyone know whether or not early 1969 cb750's had any markings on the exhaust...300? Or were they blank?

Thanks,

Mark

The early bikes had no markings "no-no" pipes.   Sandcast bikes.   Then it went to HM300

There are also a series of changes/differences as the pipes evolved.
Early ones had minimal baffles, more were added as time went by.
