Hi everyone.
My girlfriend bought herself a '79 XS400 about a week ago, so I've been doing a lot of reading on here and tweaking in the garage. The poor old girl is in pretty bad shape thanks to the two previous owners. From small maintenance items to a awful matte black paint job, and sketchy wiring repairs.
It ran really rich and had fuel in the intakes, and would stall out after warming up a bit. I took the carbs apart, cleaned them up nice, readjusted the floats to 22mm after seeing some posts here about 32mm being wrong. I used a clear tube to confirm fuel level after, and it seems perfect. Didn't sync the carbs yet as I'm messing around with other things, but it runs well at idle in the garage. The idle air screws were 1 1/4 turns out from seated, but I put them to 2 1/2 turns and the bike seems to like it.
Clutch was the stiffest thing I've ever had to squeeze and my girlfriend couldn't even squeeze it. Lubing up the cable helped a bit, but not enough. I took apart the clutch worm, cleaned it up well, and greased it up. Feels almost as good as my 2007 GSX-R.
Honestly, she probably would have been better off buying something else, but so far it's been easy to work on, and it's nice bringing something back to life after it's been sitting and neglected for years. I'm sure I will have questions for you at some point. Most likely sooner than later, haha. Take care everyone
