Re: I know! I know! Wal-mart no no!
Alright, so after port matching the intake and exhaust, trimming both ends of the stock plug wire, moving my E-clip, and removing excess plastic from air cleaner, I got my Huffy-Davidson to top out at 35mph. Very little vibration, but after about 8 miles I seemed to lose some clutch power.
I removed the cover, pulled all the clutch disks, cleaned the whole assembly with B12, adjusted the flower nut, and reassembled. Got some clutch back, but still think I might have burned the rubber disks too much. Anyone know where I can get material to make new ones? I found them premade but can't make myself pay $15+ for something I'm sure I can make...
