I just bought a used Rhino. '07 660 with 27 inch tires and a snorkel kit.

The Rhino runs great, but between 30 and 32 mph, I'm hitting the rev limiter. Shouldn't I be getting more like 40?

Could the previous owner have changed gearing or something? Just looking for some ideas on how to troubleshoot this thing. I appreciate your time!

grease inside the sheave could be dirty and not letting the rollers slide.
thats what happened with mine

 

[casmit]

so I need to open the sheave and clean/regrease it?

 

[moto92]

clean it and install some greaseless rollers and slides, then youll never have the problem again.
or you can get it all and a milled sheave from WV Hot Rod Rhino, that seems to be the hot setup now

Check out Jbs in the vendor section, If money allows call james, wv hot rod thino and order his sheave. Way more low end power to turn those 27 and have awesome pull all the way to the rev limiter.

Any chance you have a hunterworks cdi and the brother in law switch is on?

 

[casmit]

I just bought it so I'm exploring all the mods that have been done. I'll look for a hunterworks CDI.

[casmit]

ok. the CDI is just solid black...so I'm thinking it's factory.

Pull your sheave off and inspect the grease and slides on the cam plate.

 

[casmit]

If the grease is dirty in the sheave, what weight or type of grease should I replace it with?

I just used a tube of red synthetic mobil 1 before i switched to greaseless od weights. Worked just fine. You dont need alot tho.

Get rid of the 27's they look cool but their heavy mine would do 42mph with 27/11/14 I put 26/9/12's now it hits 50

We have the Hot Rod sheaves and od weights in stock for the 660 and probably everything you need to fix your problem...

Buy Hot Rod Rhino 660 Sheave online now at RuttingRhino.com

The hot rod sheave will give you lower gearing from a stop...the od weights will get to 55 mph...you need an aftermarket cdi to defeat the factory rev-limiter in order to exceed 40 mph in a 660 Rhino...

NOTE: 700efi Rhinos will hit 50mph with the od weights alone...no other mods needed...

When you combine the hot rod sheave machined for od weights you get the best of both worlds...higher top speed, lower cruising rpms, lower gearing from a stop...faster than stock acceleration...


We also have the best price on an MSD 4240 cdi anywhere at $105 shipped...


Buy MSD 4240 ignition module online now at RuttingRhino.com

The sheave/msd package will get you to 55 mph... for only $435 shipped...


Thanks for considering us...

You won't beat this set up! And that's a smoking deal! Craig at rutting rhino is awesome to deal with, you won't meet a better guy to buy from.

I got the rhino all broken down and when I pull off the clutch cover, it's clean as a whistle in the casing. I'm getting an impact wrench today to get the sheave off....but, would the grease still be dirty in the sheave if this area is so clean?

I just want to be sure I'm going the right route. Could the 27" tires be the sole cause for the 8-10mph speed reduction?
