Superdunc Posted July 17, 2020 Report Share Posted July 17, 2020 They're fucked. Won't fit anything. I'll give you £100 for them to help you out. 3 Quote Link to comment Share on other sites More sharing options...

Thunderbolt Posted July 18, 2020 Report Share Posted July 18, 2020 77mm Honda Blackbird, but the cable should be in between 2 & 3. Bimota?? Quote Link to comment Share on other sites More sharing options...

ydsparts Posted July 20, 2020 Report Share Posted July 20, 2020 I have the Keihin bible here and everything has equal spacing between 1/2 and 3/4. Worth checking again or someone has made a bit of home cock up. Quote Link to comment Share on other sites More sharing options...
Mark/Foggy Posted July 20, 2020 Report Share Posted July 20, 2020 (edited) OOh @ydsparts does anything look like 80-100-80, I have a particularly interesting conundrum. Sidedraft Edited July 20, 2020 by Mark/Foggy Quote Link to comment Share on other sites More sharing options...

Worth checking again or someone has made a bit of home cock up. Maybe 76 78 76 and the cable pull being the give away bit,, in 3_4 being the extra 7? Still very weird either way,,,, unless someone had a go at turning one of those dodgy benelli / Petronas etc motors into a normal inline 4 🤨 Edited July 20, 2020 by firebeast Quote Link to comment Share on other sites More sharing options...

ydsparts Posted July 21, 2020 Report Share Posted July 21, 2020 80-100-80 is Honda CB spacing. CB750F/CB900F/CB1100F Depends on the choke size as they are 35/37/39 respectively Quote Link to comment Share on other sites More sharing options...
