    Hello fellow 🦏 owners. I am hoping y’all can help a Canuck in getting this “machine” (currently don’t have anything nicer to call it, lol) running again. I have tried everything from rebuilding carb a couple times, to replacing fuel lines twice. Setting valves and replacing fuel pump twice...
  2. Carburetors, Tuning and Modifications
    Hey there, I have a completely stock 06 Rhino 450 with an odd carb issue that I’ve been hitting my head over. I got the rhino about 6 months ago and it had a massive backfire on decel. I tried a bunch of jet tuning to fix it, but had no luck. I then found out the o-ring on the needle valve...

    I noticed that it looked like the carb had seepage around the fuel bowl seal when I bought her, she felt dry at the time so I thought it was some old leakage. However, now I definitly see some seepage around the gasket. I did switch to an elecctric fuel pump so that may have aggravated it. I...

    I bought a used 2006 rhino 450 last year. Had no issues with it. Did replace the fuel pump, put in an oem pump. The previous owner had tried an electronic one and there was always gas dripping/running from the carburetor drain(overflow?) tube. The mechanical pump fixed that annoyance. A few...

    Does anyone know the specs for the needle jet o'ring on the 04-07 660 carb? All I can find is the part number (I think it's 583-14561-00-00) and some crappy ebay pictures next to a ruler. I tore mine by accident and was wondering if one from an o'ring assortment my coworker just offered me would...

    Have a 2006 Rhino 660. Bought several years ago and have had ongoing problems with fuel pumps. I have been through 4 genuine Yamaha fuel pumps and was recently talked into trying a completely different type of pump by reasonably good mechanic. Result is always the same lines have been checked...

    Anyone know if a rhino 660 carb will fit a rhino 450?

    so with the mods in sig, i was running a 175 main jet, 1 size up pilot, just the big washer under the needle in the middle notch, and had the A/F screw out 2.25 turns. off idle it would surge a bit, at 18mph it would sputter every now and then and at 85% throttle it would bog. now im running 170...

    so i just noticed because my motor gets pretty hot that my fan isnt coming on. why would this be? also its bogging at 60mph again and puking oil after a top speed run.
  10. Engine

    on a 04 660 on the bottom of the carb, right next to where the 2 wires mount on the carb there is a little brass thing. it looks like a carb jet and has a spring on it. it sits behind the float bowl in the center of the carb beside the 2 wires. thanks
  17. Engine
    my carb vacuum diagram has a hole in it and i lost the valve thats on the bottom of the carb. should i just buy a new one or buy the almost $60 worth of parts? is this carb any account? Yamaha Rhino 660 Carburetor 2004 2005 2006 2007 YXR660 UTV Side by Side Carb A | eBay
  18. Engine
    so my rhino will occasionally backfire REALLY loud. like a gunshot in the eardrum and also it has bad power until about 25% throttle then it will surge and take off. the rubber boot in the top cap has a hole in it and the rhino wont idle more than a min or so. if its just barly warm itll idle...
  19. Engine
    so cant seem to keep oil in it, it was sputtering real bad from 11-23 mph. then it was between 14-19. running in that range for maybe 3 mins and my temp light would come on. i dont think it was the jetting cause with stock intake its still doin it. also it was ran hard for prob 4 days before i...
