O7 rhino 660 runs good,then backfires and stalls.starts every crank,but will run short time then stalls.does not backfire everytime.seems like it runs longer when it sets couple of days.


I would overhaul the carby and check for corrosion in the main jet and other circuits
if it is a 2 stroke I would check the crank shaft seals as they may be hard and leaking mixture and running lean ( backfiring)

Why my won't my 2008 Yamaha Rhino 700 start. Has good battery. Cranks over. No codes. Good spark.


If you are only getting 65lbs of compression, remedying that would be my next move!! .. I have seen some run as low as 85lbs..run very poor too.. but never at 65lbs. You should let the engine turn over for about 5 seconds to get compression level.

2008 rhino 700 fuel injected has lots of power but crossfires at 25-30 mph what to do


sounds like you are hitting the rev limiter. If it launches that hard im guessing you have a belt or clutch issue.

2008 rhino 700 stays in low range even when shifter is in high revers light stays on and speedometer inop


Check the gear change lever where it joins onto the side of the engine/gear box. Could have slipped off or stripped the splined shaft. If that is fine and when you move the hi/lo range, and the shaft on the gearbox moves its possible the gear change mechanical levers have broken on the inside of the box.

Yamaha rhino 700 problem

STEAM FROM EXAUST


When you first start the car in cold weather it is normal for the exhaust to emit water vapour (steam) until the engine reaches normal running temperature.

I put a 102mm piston on it with 11:1 compression and now when you try to start its hard to turn over. Ive put a new starter bigger battery and checked all wiring connections but nothing has helped....


STOP TRYING TO START THIS ATV!!!

..Sounds like the valves are hitting the piston!!

Did you/your mechanic check the valve to piston clearance at max valve lift/PISTON HEIGHT??..you need at least .035" (.89mm) on the intake and .060" (1.5mm) on the exhaust.- MINIMUM - . THIS IS CRITICAL!!!

.
.....
11:1 is a pretty tall compression ratio. Are you racing this atv?.. one thing you will find out is that you NEED TO RUN HI-OCTANE fuel..NOT airplane fuel either (its got antifreeze and other additives you so not want to deal with)..11:1 might require a 110 OCTANE race gas to get it to run right... make SURE the timing is RIGHT!!..with this much compression the right fuel, timing, valve clearance, cam timing, etc, MUST be perfect!!!

I have a Yamaha Rhino 660 that has sitting for about a year. I have replaced the spark plug, but it still will not start, any suggestions?


I am assuming that your Rhino turns over when trying to start it. Check for gas, shutoff valve in the run position, gas cap vent working, do you have spark? If you have old gas try draining all the gas from your tank. Gas that sits too long goes stale and has a tendency to gum everything up.

Engine runs but has steam coming out of exhaust pipe


The ONLY way coolant can get into the crankcase is through a crack in the cylinder head, block, or head gasket. THE ONLY WAY!.

Checking compression was a good idea, and you've confirmed that is not where the leak is. It could be somewhere else within a head, the block, or head gasket.

Any gasoline engine will blow steam from the exhaust pipe on start-up and a few minutes running. May even stink, depending on how sensitive your nose is to smell.

I think your going to have to dig deeper into this, if you truly had coolant in the oil. But to tell you exactly where to look is not going to be easy.
