Post by: Lozza on June 26, 2017, 11:52:37 am

Anyone have any info of GEM reed conversions for Bultacos and when they were first available?

Have the 75 GEM catalog & they are shown in there, pretty sure they would have been in 74 or earlier

See if this link works

The CZs shown are pre73 models if that helps, not up on my Bullys enough to be able to tell age of motor in the photos

I know they were available pre '75. They use to put them on the early CR's.
