What methods have you lads used to fit c15 yokes to Tiger cub frame, Know this might be boring old hat but could save me hours of messing.

Sorry you haven't had any replies , I cant help as I have never owned a pre65 bike        

maybe you have had no replies because you are thinking of using actual real old 1964 parts ?

most people these days would be fitting - New Billet "pre65" yokes into a New "Replica Pre65" Frame 

Have you contacted any of the classic specialists ?  like Sammy miller products , Terry Weedy 

I think that the stem on c15 yokes are different to tigercub, the only way would be cut the stem out of tigercub yokes and retro fit to c15 yoke. I looked into this for my own bike but that was as far as I got. Also bear in mind the spindle on wheel may need attention.  

Thanks for the replies, would like to keep the bike of the era if you like, purchased a set of heavyweight internal sprung tiger cub forks in the end, a friend has just carried out the mod Corky thought about and has made a great job not sure my welding skills are up to his standards though.

I’ve got heavyweight forks with internal springs but I put some 3ta stantions which are a bit longer with original cub springs and made a spacer for the take up difference and add a bit of pre load and I use a 7.5 weight oil . They work well for me at the mo as I’m not good enough to justify spending over a grand for some reh forks.
