The bike is 21 years old and sat outside for at least half that time. I got the float bowls off but could not get the diaphragm covers off. A po stripped the heads on the screws. I was having the problem where she would idle, but bog and die with more than 1/3 throttle. I noticed that one carb was clean and one was all gunked up. The two were slightly different, leading me to think that one was replaced a while ago. On the gunked one, the slide took a long time to return to the closed position, so I started to spray all of the passages out and cleaned everything I could access with a wire. I removed the jets and saw that the ones in the older carb were plugged or restricted compared to the other. I also saw that the float valve was stuck in the in position. I soaked the jets and valve in lacquer thinner for an hour and easily cleaned them out with a brush and copper wire strand.
I am waiting to get the carbs back on, as the afternoon thunderstorms halted that. My question is twofold:
1) Do I need to worry about getting into the top of the carb, or should what I did be adequate? I think the diaphragms are good
2) I removed the airbox when I removed the carbs and plan to use pods. Does anyone know what the new jetting will have to be? Should I put the airbox back in to see if this fixed the problem and then remove and rejet later? It was a pain to get it out and I would hate to have to do it again twice. I will have to buy a new filter for the airbox and I would like to avoid it. If I leave it off, will the bike run with the stock jetting well enough for me to know if I fixed the problem?
