Hi guys- I have a stock 07 rhino 660 with about 1200 miles on it. I have been having the same problem with it for about a year now. I canít seem to figure out whatís wrong with it.
What it is doing while normal trail riding is it will start backfiring real bad(sometimes will die) and runs like it is running real lean. And it wonít let me go very fast but I can usually make it back home just barely! It seems to do it when it is hot after running it for awhile, but Iím not positive that that is the reason for the problem. It seems like it is fuel related still but maybe not.
I have put in a new carb kit, new fuel pump, new fuel line,fuel filter, spark plug, cleaned the carb at least 3 times even though it wasnít very dirty, checked the fuel pickup from the tank. It starts and idles 10 times better, but still the same issue? Any help would be much appreciated. This is getting very frustrating!! Thanks GuysÖ.
