Hi Juergen
I´ve looked with interess at the latest developments on your 4FL. Looks good, really good
You caught me on the swingarm pivot being positioned more upfront on the 4FL frame.
I´ll dobble tjek, but even if the pivot in the 4DL frame looks to be further upfront - the measurements I took, points to the longer swingarm being the one that gives the extra wheelbase on the 4FL...
Will have to tjek that... not that 10-15mm will make such a difference can be corrected if wanted with an ekstra link on the chain...
About mounting the engine, well, cutting on a 3XV swingarm has been done.

Some other factors - like the use of bigger chain sprocket on the front, moves me towards fabricating an engine mount that will attach to the chassis... not a big problem (I think... wish, maybe, who knows
)
Thanks for the answers, always nice to have some constructive criticism as well, helps one stay sharp
Thanks!
