Just got myself a 2008 rhino. Bone stock. I used to own a Teryx. Not too impressed with the power and speed of my rhino so far. It seems to be hitting the rev limiter at 40mph. What needs to be done to juice it up a little? Don't want to do anything extreme, just get a little more speed and Perfomance out of it. Also, when I put it in 4wd I get a thumping noise at stand still idle right under the seat. Doesn't seem to effect the performance at all but don't understand what it could be. Thanks

Check this out:

MSD CHARGE FI RHINO 700 :: IGNITION AND EFI :: RHINO 700 :: YAMAHA UTV :: Yamaha :: Team Alba Racing

The best ECU for a Rhino700 and a 3D version is soon to be released. You may want to check your clutch/belt if the noise is coming from beneath your seat.

Get yourself a JBS Hot rod sheave....it will give you gobs of low end torque (you will seldom need low gear), and, it will get your top end to around 50mph!!! An MSD will raise your rev-limiter; but, I would hold off on it till you went w/a cam and/or exhaust. Give James a call next week....he can hook you up with whichever way you wanna go!!

Get a JBS sheave! AND a MSD from Nate.

you'll be in the 55-60 range.

Buy hot rod 700 sheave w/ grease less od weights and sliders online at RuttingRhino.com

The hot rod sheave with od weights will give you lower gearing from a stop...faster than stock acceleration...lower cruising rpms...and a top speed of 50 mph at the factory rev limiter with no other modifications needed...

If you raise the rev limiter with the MSD you will get 55 mph top speed...you will need more than stock power to get to 60...

Also recommend a gold secondary spring...better climbing, better back shifting...better engine braking...better grip on belt...

Like Craig said, get the spring as well...you'll really notice the difference on hills. The MSD will do away w/the rev limiter; but, you won't see the full benefit of the expense until you upgrade your cam or exhaust. If you do the sheave and the spring, you will stay right on the razr's ass on the hills...they'll still smoke ya on the flats though!!! my .02

Thank you all for the advice and tips. As a prior Teryx and Brute Force owner I am drawn back to the side by side. I was drawn to the rhino for its looks and the ton of options that are available. Was real surprised of how choked down these are out of the gate. Is there a reason why Yamaha did this.. Legal reasons etc...?
Thanks again and look forward to start the mods to get this thing faster.

The only thing for speed is aftermarket clutch kits, sheaves, etc. The noise when in 4WD I've been told is normal. Due to the length of the front drive shaft it causes a vibration when in 4WD at stop and low speeds. I have this issue with my 2011 rhino 700 and got that answer from the local Yamaha Dealer and they inspected it and found nothing wrong.

The rhino's top speed stock is around 40-42mph with the 700cc motor from what I've found. They'll go faster with aftermarket transmission mods though.

I would to a sheave and spring first, second a new ecu, third a pipe, fourth a cam, and so on. You will get the most bang for your dollar with a sheave.

Absolutely no question, go with the hot rod sheave! Best sheave on the market! Great low end and pulls awesome all the way to top!
