differences between the 660 and 700 engine

I have a line on a number of 660 Grizzly's priced right. What are the real differences between the 660 and 700 engines besides FI on the 700?

Pro's and cons......

Thanks.

I Believe They Are Completly Different Motor. Besides Efi Different Valves, Head, Crankshaft, Forged Pistons, Clutch, Sheave. There Are A Few More Things That Are Different That I Read Some Where I Believe On This Forum Or A Magazine.

The 660 has a 5 valve head while the 700 has 4. What's the reason for less valves; lower weight?

less noise with the 4 valve design. the 700 is much more of a utility based engine. the intake angle on a 700 is also greater than the 660 meaning it will not build as much top end power but they have to do that to get the low end. the reason yamaha started building the 5 valve design was because it can have great volume for top end power from the three intake valves but because they are small it will not sacrifice low end power. you really cant compare the two. bottom line is if you want to go fast in a rhino get a rotax 800 engine!

After all the pros and cons for 4 valve and 5 valve, it really comes to a wash.
One of the main negatives for 5 valve for a manufacturer is cost to produce. The valve area for a 5 valve head is nearly identical to a 4 valve head.

Which engine runs quieter? I have been thinking about getting another SxS either a Rhino 700 or a RZR still on the fence about which one. Either way the wife drives the old Rhino. I hope she didn't hear me LOL.

also if you are up north the 700 has fuel inj. so it will start easier when cold. however its more stuff to go wrong. if you want a quiet smooth runing rhino 700 is the way to go. if you are like myself and love to modify and tune engines to the maxx you are limited on what you can dowith the 700. no 45mm pumper carb kits for the 700. also another mega plus of the new 700 rhino is that its equiped with 4 wheel disk brakes!!! now if yamaha was not a bunch of turds they would sell all of us poor bastards with 660's an upgraded brake kit at a discounted rate since the single rear disk is clearly a terrible design because of how small it is! whatever you get they are both great UTV's
