original powerrol stoker bottom end from when i raced this bike back in the 70s 54mm piston late model takegawa roller cam roller rocker head machined to fit the early bottom end PVL ignition 120cc pop Yosimura 24mm flatslide carby
so the original swing arm was a Franks racing product idea and my dad built it off drawings from Kelvin Franks in the 70s one off as I haven't seen or know of any more when I went to restore the bike the old swing arm was rusted and a bit rough in its appearance as my dad did all the fabrication so instead I search for a close fit and modified the alloy one to fit its originally off a 125cc pit bike but needed alot of tig work to make it fit but handles well and holds my 90 kgs
Wonderful looking build!!
Therapeutic sound for me at least.
