Hi every one, i have a 86 Honda XL600R and lately its been really making me reconsider keeping it. Bikes done a shade under 10,000 miles and since recently its been giving off a popping sound and shutting down at slow speeds, it used to do it occassionally at first but now u cant take it out with out it happening. It soulds like a lean sympthom but the spark plug does not reflect an overly lean condition. When it first started tto get real annoying i discovered the air filter had its sponge disintegrad so i pulled the carbs and they looked very clean and since been running with out air cleaner element. I even changed the gas thinking it may have had some water but it did not improve. I have ordered a new uni flow filter but have not yet installed it. Does any one here now where i can get some bigger jets as the bike is fine otherwise(it will run pretty hot on steep rough trails where u have to go slow and i think this is because its lean)
