side engine fan

i know i've seen this before but i think it was on rf, but its the fan on the right side of the motor i was just wondering if i need this on and whats the purpose of it. thanks

It blows air on the exhaust I took mine off and left it off when I put a new piston in mine a few mo.s ago.

Yep, Just blows air across the exhaust. Couple things tho. When I took mine off(just the hose) the exhaust hanger tried to catch fire. Some have said, It will melt Your hanger then You will crack the manifold. Others have removed with success. The down side of the fan is, when it gets water or mud in it, it bogs the motor real bad.

removed mine when i installed my hmf , no issues to date

if you have stock exhaust it cools the rubber mount. if you have aftermarket exhaust, ditch the whole setup.

I pondered running inter my intake for a supercharger... lol!

Imagine what would happen when you went into the water and pumped a few gallons of it into the intake ..... ScubaCharger ....

I removed mind because it was bogging down in the mud. I melted my exhaust mount the next ride. I've been dealing with the aftermath since. Pretty sure the manifold is cracked but haven't tore into it yet. On the plus side I tear thru the deep mud now.

If you're running stock exhaust I wouldn't suggest ripping it out.

thanks for the info guys guess ill leave it on for now

older thread but i was thinking about taking my side fan off as well i have pro-tec dual exhaust so i should be safe? when i remove the fan do i need to put a cover or anything where the fan was? thanks

Where are those fans located? Are they electric, or bolted to the sheave? I know my 700 don't have one, but I've heard alot about the bogging down from it.

Its on the passenger side. Bolted to, i guess the crank

yes it bolts to the crank

so would i just remove the fan an leave the shroud on the motor or remove it all
