As you can see, I'm not a designer, but it's the best I could do at this time.
A few observations: in this configuration, the acceleration in 3rd and 4th is scary. I'm 72 and this bike is leading me to 'hooligan behaviour' Ha!
1. The side covers need a redesign, but I'm sorta stumped. (1/16" alum checkerplate)
2. rotated the shift lever lower so I don't have to raise my foot
3. The tank speedo is totally useless, can't see it from the seat.
4. need help wiring the tach
5. carb mods eliminated the backfires
6. the taillight must be from a trailer, I can have a running light or brake light, but not both.
7. my friendly landlord just OK'd me doing some welding. Helloo harbor freight!!!! A new skill to learn via u-tube
8. when I sell my Vulcan, gonna buy another S40 and do another improved re-design.
Singles Rule!!!!!
