Today I cleaned the carbs on my 1982 Yamaha XJ750. It had been starting harder and harder the past 2 summers and I hadnt even tried starting it this summer and its already the end of July. So getting the carbs off the bike was not easy but I kept wiggling and tugging and finally got then to pop free. I was pleased at how easy it was to disconnect the choke and throttle cables. So I followed a real good video on Youtube on how to clean the carbs just to be safe. I have taken apart and cleaned alot of carbs over the years starting back in the 70s with snowmobiles. I wasnt surprised to see how gummed, gooped and gobbed my carbs were. The stinking gas they are selling us these days should be a crime. The bowls, needle and seats were the worst. 2 of the needles were actually glued in and I had to pull them out with a pliers. The main jets werent much better. So I used my big stainless steel carb cleaning pan and poured a couple of inches of new gasoline in it. I soaked all the needles, bowls, screws et etc in that gasoline as I took them off the carbs. I also removed the choke needles and the other little screw in jet, I think they called it the idler. So after a good soaking I started the reassembly process. I has 2 new cans of carb cleaner and one can of DIET MOUNTAIN DEW because you dont want to get thirsty in the middle of a carb job. I squirted all parts, holes, needles as I reassembled and gave the carbs a real good bath inside and out. Tomorrow I will put the carbs back on the bike and hopefully report back here with good news of a sweet running 750 (and easy starting)[img][img][img][/img][/img][/img]

Good example of why you should use gas stabilizer and drain the carbs for storage?
