Need help please
Well, I'm not entirely sure this falls within the carbs and fuel system area, but I'm guessing here.
I got my bike to start, however I'm getting some backfires from it and it also seems like it's only running on the rear cylinder. I came to this conclusion because if I remove one or both plug wires from the front cylinder there is no change in how the bike is running... if I remove a single spark plug wire from the rear, the bike stalls... I didn't remove a second one, it'll probably die if I do.
What I did to the bike recently was to plug the reed valve hoses and I also took out and cleaned the carbs. I removed all the hoses that connected to the reed valve hoses, including that thing that is at the middle, where the vacuum hose from a carb plugs into and another hose goes into the airbox and the other hoses go to the reed valves (don't know the name of that thing in the middle, so this is my description, hope you understand it). I didn't think this stuff was necessary for the bike to run, since I'm plugging the reed valves anyway it didn't seem like there's any use for them.
I also adjusted the mixture screws 2.5 turns out.
Here's something else I noticed. I have 2 inline fuel filters, one on each fuel line. The filter that goes to the carb that IS working is never full, you can see fuel in it but never full. The filter that is in line with the cylinder that is NOT working is always full of gas.
As I type this, I'm thinking the first thing that would come to mind is a clogged filter... I'll go try it without the filter just to rule it out. I'll report in a bit... meanwhile, what else could it be?
