750 v-twin performance & reliability?

Hi folks, I'm new to this forum and sxs's. I last purchased a atv in 02 and just recently sold it and I'm looking at buying a sxs by this fall. My question on the Teryx, I was reading my latest issue of ATV Action magazine. In it there's a article called "Kawasaki v-twin performance and reliability secrets". The magazine and Kawasaki v-twin, four stroke tech, Mickey Dunlap talks about the problems the Kawi motor has regarding the small oil pan/sump (2qt.) and how oil is blown from a breather tube behind the rear cylinder into the air box during heavy high rpm use and can cause engine failure if not properly maintained do to low sump oil not being picked in the pickup tube esp. on off chamber riding. What is your opinion on this and is there anything I should know that you guy's have found owning these. This is the one thing that I was concerned about everything else seems to be pretty bullet proof. I'm a trail rider and don't do a lot of high rpm riding my main use will be plowing my driveway, hunting and ground maintenance, I have 8 acres of woods. Any input on this subject or anything else would be greatly appreciated. Safe Riding!

any motorcycle/ high revving engine will burn or use oil, with the cheap and simple fixes most the issues can be fixed. like mentioned above just make it a habit to check the oil and stay on top of maintenance and they are very reliable. i have one stock and one custom and have been trouble free for three years now.

Several vendors have siphon breaks that really solve the puking oil into the plenum problem. The simple stuff like checking fluid levels and regular maintenance keeps these things very reliable.

yes the article is rite but you just adapt and overcome main thing is leaving it stock and keep it maintianed always checking the oil and air filter.once you mod it the reliability starts to go down like any high performance motor would.alot of guys add another style air filter better cooling and or oil cooler and remote filter.i did all the air box mods and a uni air filter plus oil cooler with a remote oil filter witch the cooling fan seems to come on alot less now,i think there a good machine you just cant neglet them like some old honda atv,its to bad you not looking to buy now i have a nice teryx i'm selling with all the bells and whistle's perfect for what you want to to do just like ive done good luck

Thanks guy's for your input and I wish I could purchase now but I just purchased a wheelchair van for my wife and it's a chunk of change, six figures so I have pay a bill off first and that won't be until September.
I was actually looking at three sxs's the Teryx, Rhino and in a little different category the Polaris Ranger 6x6.

From the start I bought a 02 Grizz that served me well and still runs great today with nothing more than normal maintenance and a set of tires in ten years, anyone would be happy with that. So the Rhino was at the top of my list then the Teryx because both have good reviews.
The Polaris is something I have been looking into because my brother-in-law has a 99 6x6 that has served him well even with the kids beating the crap out of it. I started doing some reading and asking questions on Polaris forums and get 3 people saying "there good machines" and 1 saying "it's the biggest peace of crap out there" and showing a list of thing's that have gone wrong since they purchased it. It wasn't this hard when I purchased my atv in 02.

The Polaris has me baffled I've never seen such a big difference in 1 owner vs another, it's like stay away from anything built on Friday because they are junk but the one I have that was built on Tuesday works great.

Any how I like both the Yamaha and Kawasaki but I'm looking for that extra hp and torque that Yamaha fails to do anything about so the Teryx has me very interested and I'm looking forward to listening to what you guys have to say about thing's you have done or are doing in the future.

By the way the one fix my magazine and Mickey Dunlap talk about for the oil issue is. Some of you may have heard of it the YFZ breather mod. He takes a Yamaha YFZ450 vent box that serves the same purpose on the quad and is the right size for the purpose. He say's the size is right because it's made for a 450cc motor and even the 750 has only 375cc half of the 750 breathing at one time. He extends the hose coming out of the motor and with the YFZ box mounted higher than the motor they plug it into the middle nipple on the box. Then they run a hose out of the lower nipple on the box and drain the oil back into the gear changer cover where you put a 3/8" fitting. He say's the top nipple is just a vent that can go anywhere and you will need to plug the air box hole to keep dirt out. Also changing the oil often esp. on the 750 being it has such a small oil pan will make a huge difference in the life of the motor. It was interesting read and I learned a lot. If you already know about this sorry for boring you but maybe it will help someone.
Have a good Super Bowl Sunday everyone and stay safe. I'm a life long Steeler fan but today I have to go with the Giants.

Thanks, 03maxpower. The machine from what I ready has a lot of potential for more hp but it also is very strong on it's own. My 02 Grizz had a KN air filter, HD front bumper, Warn 2500 winch and plow, Mud Lite XL tires and rock sliders and that's about it and never gave me an ounce of trouble other than a valve adjustment in 10yrs. So I know what your saying. Give me a camo Teryx with a Curtis RCS cab (tired of freezing my but off plowing) with heat, a plow, winch, lights and good tires and gun rack and I'm a happy camper for at least 24hrs or till I find a new accessory.

I don't know, maybe Chris from Benchmark or Brian from LTI know for sure.

Reading the article (this is the February issue) it say's Kawasaki has made several attempts to solve this problem with no luck. Seems the after market guy's have better knowledge of what has to be done to fix the problem.
I'm basically looking for a reliable machine I don't have to worry about every time I take it out trail riding or plowing my driveway. Suspension bushings, bearings, ball joints and tie rods seem to be the hot topic with the Ranger. It's tough because you don't know the complete story unless you were there and actually seen the problem and how it was driven. I like your answers so far on the Teryx guy's thanks for listening.

We have an 08 that has seen about every type of use - hauling logs, dunes, trails, snow, mud, rock krawling, GP and short course racing - and is reliable as hell. No siphon break, and every once in a while on a gnarly climb it will blow smoke (oil in plenum- freaks people out). But we check oil every ride, change it at 25hrs, keep air filter clean, check valve adjustment, do the maintenance. With both the stock and MT suspension even on some insane terrain and racing there have been no suspension, cv, ball joint, bushing, drivetrain issues. While I have seriously considered brand P, but the Kawi issues are minor in comparison the what I have read. I think you will be happy with a Teryx for your intended use.

That's exactly what I was hoping to hear B-Coyote. I have 8 acres of woods so hauling wood is one of several thing's on my list it will be used for. Nothing extreme just ground maintenance, hunting and easy and some moderate trail riding.
