Hey everyone! New to the forum, but been around small engines most of my life. I just recently picked up a '79 XS400, and decided to get it running again (present for gf for getting into Vet School). I got it running, but only on the left cylinder, and I'm stumped as to why. Here's a list of everything I did to it to get it running in the first place:
-changed oil/filter
-cleaned gas tank from rust/varnish deposits with vinegar and BB's
-thoroughly cleaned carbs with carb cleaner and compressed air
-changed fuse box with updated unit that used blade style fuses (old buss fuse holder were corroded and causing bad connections)
Got the bike to fire and I thought everything was good, but it wouldn't rev up when I applied throttle. It idled fine, but as soon as you applied throttle it bogs and dies. Pulled the cap off the right side while it was running and realized it wasn't running in the right cylinder. Pulled the plug, laid it against the head, and noticed that I DO have spark. The spark plug was also wet with gas, so I know I'm getting fuel to the right side cylinder. I'm currently stumped as to why it's not actually running on the right side. What should I check next/swap around to see if we can find the root of the cause?
Any help would be greatly appreciated. Also, here's a picture of the bike.
Thanks!
