can someone recap this whole posting to give me the mods done to improve performance for the bobber? I have the 250rtc and plan on doing a few mods:
34t rear sproclet, ngk sparkplug, racing sparkplug harness from autozone, adding more ground wires so the bike cranks up easier

Did I miss anything? And when I say performance don't think I am treating this bike as a pocketbike and I redline every second or drive crazily around the streets, no, its just that I do a lot of highway /interstate driving in orlando and speed limit is 50mph with everyone going about 55-60. on this bike I have maxxed out at 75 ( I weigh 150 ) and even when riding at 50 it feels like I might be pushing the bike too hard, any info? also at 60 mph I am in fifth gear at 5000rpm, anyone have info on gear change ratios? such as speed/rpm/gear. I have talked to the owners of http://china-moto.com/cm/ and other members on their site and they are selling custom aluminum sprockets for the rtc and rtb, and they have a lot of knowledge about these bikes also. One of the moderators and owners, almonp, posted that with a rear 33t sprocket on his rtb he was able to do 75 in 4th gear, but in first has to rev up to 2500rpms to get it moving without stalling. What do you guys think?
