05 Kawasaki 750 brute force problems

[Christopher Freshwater]

I just got a 750 brute force was not running been working on it all day finally got it running but rear cylinder acts like it cuts out and then starts working again and the fan does not come on

[Christopher Freshwater]

Finally got it to run right still having problems with the cooling fan any suggestions

Hey Christopher welcome to Quadcrazy, so glad to hear you got it running right.  The cooling system fan runs off a sensor that’s mounted in the radiator. On that sensor are two wires. While the bike is running take the two wires off the sensor and jump them together. The fan should come on.  If not then test the wires for 12 v. If you don’t have 12v then the fan power is obviously not there and it’s a mater of tracing the wires back to the source.  Keep in mind that some manufacturers have two points of protection in place, one is the fuse at the fuse block and the other is an in-line fuse that’s going to the fan.
 

If you do have power at one of the two wires going to the sensor and when you jump them together and the fan does not come on then your fan motor may be bad.

I figured out the fan now I’m trying to figure out why my Exhaust glows rad when I run it

[Frank Angerano]

Ha we just  heard his story from another member who had a similar problem.  Turns out that when he was rebuilding the top end he put the coolant hoses on and reversed them by mistake.  I don’t know if you or anyone else worked on the atv but look there first.

I will take a look when I get out of work 

[Frank Angerano]

Ok man let us know how it goes.

The coolant hoses are correct I’m kind of thinking it is running rich or lean

[Frank Angerano]

I don’t know if that’s the case, could be but you would have a lot of black smoke from the exhaust?

Make sure your not running a hot plug and make any adjustments you think on the carb if you know where to set it and give it a shot. If not look for the usual suspects like the thermostat and water pump.  Check the coolant etc.
