stock carb questions

[killerbanshee]

My banshee recenctly started running a little rough. It is stock except pipes and I have yet to do any engine work to it. It has ran great since I've had it, but I took it out this weekend and It started running a little rough. It seems a little boggy all around and stumbles a little through the mid range. It is great on top though. I changed the plugs before leaving and gapped at .030 like usual. I used the gas from my last trip which was 2-3 weeks old and it has been sitting in the shade in my shop. The plugs look like it is running rich all around and a little more rich on the right side. Here lately a couple times after starting it on a cold-wet morning it acts like the throttle is sticking but that is not the case. you can give it a little gas and then let off and when you press the throttle a little it goes right back to where it was. Kinda feels like something might be sticking a little in the carbs. It's not a sticking throttle though. I am thinking about tearing into the carbs, but like I said I haven't done that before. The only carburetors I've ever worked on have been on cars. Compression is 112-115 in both cylinders. Should I just clean the carbs or should I look at my jets and mixture screws too. The bike has been piped and jetted and it ran good before so I haven't changed anything on the carbs.

 

It still has the tors on too.

Yea pull the carbs off and clean the pilots and mains, then give the rest of the carbs a good wipe down.

lube te cables, inside the tors boxes, too. if you leave the thumb throttle cover off, you can watch the slack in the cable when this is happening. also, check for airleaks.
