Did a bit of searching, can't really dig any info up on the subject. In wondering if there are any other bikes that have 41mm fork tubes that I could change out my upper yoke for that models without any modification? A mechanic buddy of mine said you could pretty much put any yoke no matter the diameter if I were to have spacers made. Anyone know of anything in regards to this?

 

The fork offset of the yokes would have to be the same as the F2. That is the distance of the fork center line to the steering stem center line. Here's a link to a list of bikes with 41mm forks that is on another website. Its an FJ Yamaha site.
