Hey, I've been reading up about your build, so I had to join in on the zuki talk. I just recently got a bobbed out and hard strutted 81 gn400 for $450. The guy couldn't start it when I went to get it but I fell in love when I sat on it. Got it home and started digging in, first thing I did was tried to hear it run..the guy cut half of the exhaust out and put a pod filter on it and I guess that fucked with the airflow. When I got it started finally, it was idling at 6-8 grand and was loud as fuck! I'm new to bikes, I had a 83 cb550 but it needed work and just ended up selling it. But I do NOT want to get rid of this bike. Im asking for advice/help.. I really don't know where to begin..please help!
