It is hard not to love them, the carbs and tanks need to be spotles for them to run right. I have a service manual if you need it, check the rear drive hub to be sure there is oil in it, 70cc of gear oil if I'am not mistaken, that sometimes evaps or leaks away and can kill your final drive. Mine will hit 31-32 with my 200lb ass on it so if you are lighter you maybe could see 35, the proma pipe is the shit, no carb mods needed and adds quite a bit of power. They use a 25:1 mix rich by todays standards but if you use good oil it should be cool, that is what I use in mine. Due to this rich mix however if they get out of whack they can foul out quickly or pluck exhaust/ports. Enjoy your bike!
