So I'm going to help my brother work on this problematic za50 that he has been working on for a while. I wasn't there for the building but I've heard and had him describe a few of the problems. I've never worked on a za50 before so I figured I would shoot some of these out here.
magnum has new 70cc kit and exhaust, treats cdi, daves phbg knockoff carb,
the inside is still pretty stock.
1. bike can start, i guess now sometimes you have to hold the clutch for it to stay running? did he put together clutch assembly wrong?
2. When the bike was running ( when he was trying to jet/adjust timing), the engine sounded like it was very clanky and unusually noisy. piston slap? something loose inside?
and 3. The bike has been on the verge of running. when trying to jet and everything else before, the lowend was just real sluggish. just kind of slow overall, so any ideas on what is missing or wrong?
Again I know these are general things, but I'd figured I'd ask just in case there were za50 specific things I needed to know about.
