WW Zuigt MAN!!!
I haven't made any measurements of a tank.
My idea is to measure from the model you want:
The lenght from footpegs to steeringhead, seat height,al the places that make the newer model different by feel.
NOT only looks like JJ motor. I put my RMZ/KXF250 seat on mu uncle's K5 once. Just to see how it would be different
than stock. Than just tape the new shrouds on to feel and see how it looks.
If you have placed it and have the right position. Then "just" fill the gaps up with fueltank.
Have you desidid what look/model you want Menno?
?
This pic is a rough idea what to measure.
