So far, I've only updated the bike with flush mount front signals, integrated LED tail, FE kit, and frame sliders. Anybody have some advice on what to update next?
Interesting, what sort of air-filter model and manufacturer? I would also mention the dual-headlamp mod is worth considering. Check out BikderDude's post on how to do it.
I would very highly recommend new fork springs and heavier fork oil. For only $120.00, and 90 minutes of work, you can make the biggest overall performance change to you scooter. It will ride and handle much better.
The dual head light conversion is very nice too.
Exhaust and filter are nice, but they are more for aesthetics instead of performance.
i agree on the dual headlight. I did it for free with stuff i had laying around. Also like Hellgate said the fork spring and oil sounds like like a deal to me!
