Good thread, interesting to hear about weight mods, not oft discussed around here. Like others have said, I think your biggest savings would be around:
- Lightweight wheel/tire
- Lightweight exhaust
- AGM battery (better cranking performance, better lifetime, lighter for the same capacity, better charge retention)
- Lightweight (fixed?) front seat(s)
You could really get some decent savings out of these pieces I'd think. Not sure how much difference it would make in acceleration, but would be interesting to compare.
