I think our main problem with that bad jet was a failure of knowledge when it came to the full assembly. We simply overlooked it the first time. Even after immediately cleaning it we received a throatier sound from the bike which was telling us more so that the bike was sucking more air but I could be wrong of course. I'm going to test that plug on that side right now and if that isn't the problem I will move onto a deeper carb cleaning like suggested. One quick question though since I'm sure you're correct about the tank having a bunch of junk in it regardless of any other problems going on... Are we talking about the fuel filter on the petcock? or are we talking about an in-line filter between the carb and the petcock? If in-line, where can I get one of those. Thank you very much Monkey and Drewpy! I'll keep ya updated.

Hello everyone, I'm sorry to bother you all with my issues but I've been watching the forum for quite some time and I could really use some help. Several weeks ago I was gifted a 1981 XS 400 Special. I don't know much about bikes but with some help from my friend we have since done the following: Replaced clutch springs & friction plates (shifts like a pro now) Repaired the kick-start (easy fix and it's fun to use) changed the headlamp assembly to a high end halogen (mmm light) Rebuilt and cleaned the carb Replaced the battery And that's about all I can think of... Well today me and my friend thought we finally had it! It seemed like it was running great until I tried to run it up a hill near my house and the engine started dogging. It seemed to drop rpm with more throttle. We came to find out that the engine is only firing on one side. We checked out the carb again and noticed the main jet on the one side was clogged. After clearing it out it continued to perform the same. Thinking that the issue might be electrical we reversed the sides in which the spark-plug cables were on. Swapping cables did nothing. So we decided to swap the ignition coil along with the cables in order to see if we could get a change. I'm unsure if this was incorrect in the first place as this is the first time I've worked on a bike, but this resulted in the bike failing to start but backfiring quite a bit. If anyone has any insight into why this could be happening I'd greatly appreciated it. Thanks, -Ken
