    Haven't run the rhino this summer, but was doing some routine maintenance to keep her happy. Hoping to get a little rain and run some washes, but the ***** started acting up on me and now I'm stumped.... sort of - I think I know what it is now but would like some more opinions. I trickle...

    My 06 660 when running it at full throttle cuts out, misses and has been backfiring. Can anyone tell me where they think i should start to fix the problem? It seems to be fine a low RPM. So far ive changed spark plugs and put new gas in it. I will be checking the valve clearance and...

    I have a 2006 special edition 660cc rhino and I am having all kinds of trouble with this thing. When I bought this thing it was running rough and would back fire. I decided to rebuild the carb and go ahead and jet it while I was in there. I have added a full white brothers exhaust so I went...

    I have a 2007 660 Rhino that recently just started missing and running rough after 20 mph. It almost sounded like a fouled plug, but Rhino 660 only has one plug. Engine starts fine, idles fine, and problem is only noticeable after 20 mph when you step on the gas more. Suspecting fuel cutting...

    I just put on a high flow fuel pump on my 06. Now it only runs at high rpm, can't get to idle. Stock carb, have messed with idle adjustment. I have an Edelbrock carb for the machine but was having issues with it not idling without tapping the throttle and then it would die with the stock fuel...

    Recently had fuel pump issues, and was reading about the silicone coming apart and stopping up the pick up, so I also checked that. Mine is coming apart and getting into the fuel filter. My question is, do you really need to put the silicone back after cleaning it off the pick up, or will the...

    hello, Just bought an 05' 686 rhino last month, haven't had time to actually off road it, but have driven it around the neighborhood (and they thought my cars were loud) any way when im at a stop and just stomp the throttle, it either boggs and picks up or it stalls out, If I give a half to a...

    I have a 06 660 It just turned off like I turned the ign switch off, would just crank after that. Let it sit for 20 mins and fired right back up, ran great for the rest of the day. No temp light came on. (Maybe bad cluster)?? Does the 660 turn off when overheated? No coolant leaks, everything...

    My dad has an 07 Rhino 660.... We have some trouble every now and then whenever we go to start the engine. It just keeps cranking and cranking but will not start. It just seems as if we lose all the gas prime in the lines. We have put new fuel filters on numerous time, yet every time we inspect...
