i finally made it thru the terribly slow break in period on my rig and i got 42.4mph with a stock 44t setup on 700c tires. i cant wait to add all the goodies i can starting of course with my homemade boost and no2 kits and the first reasonably priced 32-34t sprocket i can get my hands on. if anyone knows a site where i can order a pretapped manifold and a small sprocket id love to hear about it. ill post pics when my bike is a little less ghetto. i built it from a rawmotors.com 80cc slant black kit and a diamondback roadbike frame i dug out of the trash. i currently have a 26in mountain bike tire on the front (yes thats the speedo side and i did calibrate my speedo accordingly) and i finally got brakes my kit told me to do my break in at 15k but that was barely idle speed so i did my break in at 15mph instead doesnt seem to have had a negative affect yet. also, pending some further experimentation i seem to gain a signifigant power increase when i remove the baffle. does anyone sell baffles with oversize bores? anyway ill keep yall posted thx for any help u provide
