1981 XJ 650 Maxim The other day I was riding and noticed that the bike had started sputtering upon acceleration. The bike has pods (I know) and a 4 into 1 with a straight pipe, It has been rejetted and has #42 and #116 jet set up. I did the valve shims late last year so they should still be in good shape probably only 500 miles or so. I thought maybe I had a stuck float. I pulled the carbs and the #2 carb pilot jet was lose and no longer seated it was just floating around. So since I had the carbs off I went ahead and cleaned them. I did not split the rack as I also had done throttle shaft seals late last year. One thing I did try on one of the needle jets was to polish it with a metal polish pad. It is similar to a scotch brite pad but made specifically for metal. So when I did that I saw that I did change the finish from smooth to a somewhat "less smooth" state. It went from shiny to a cloudy color. I stopped and didn't do anymore with that pad. I did wipe it down with liquid carb cleaner and put it back in. I didn't think I did enough to make it not operate normally. I soaked all metal parts in carb cleaner for an hour. I did not soak the carb bodies or diaphragms in carb cleaner. I know it doesn't like rubber. I reassembled everything bench synced. The bike fired right up and then I vacuum synced. Bike still sounded sputtery. mostly when I rolled on the throttle. I had probably 40% less power. I went to the manual and checked for spark -yes. checked both sides of the coil. One coil was testing at about 11000 ohms and the other coil was at around 15000 ohms. I swapped out the coil with another coil that I had on a parts bike. Both coils now tested at 110000 reassembled and went for another test ride. Still sputtering. Before I cleaned the carb and noticed the jet was loose I did have gas on the floor. I couldn't tell for sure where at on the carb it was leaking from. I assumed when I cleaned the carb that it was the pilot jet being loose and not letting the float to operate properly. However now that I have reinstalled the carb with everything tight I can see that it is still leaking gas and it is coming out of the # 2 pod filter. So I am wondering if running it wi9th that jet loose for about 10 miles home flooded the engine oil with gas and or caused piston damage. I do not have a compression tester and I am going to pull the carb again and replace the needle jet that I "polished" I will clean it all again and blow air through the passages and bench sync and vacuum sync. Would anyone have any other ideas? I am going to do an oil change just to be sure there isn't gas in the oil tonight as well. Also would a loose pilot jet on one csarb cause piston failure if ran for 10 miles or so?
