03 And Up Grizzly's Burning oil?????

[Diceman]

also just read on another site that some guys who use Amsoil have had consumption issues and when they switched brands , problem solved....anyone else hear of this?

anyone hear that some people who use amsoil had a consumption issue but once they switched to another brand they had no oil consumption issue??

If it used oil from day one why didn't you have it repaired while covered under warranty? It sounds like yours had a ring installation problem from the start. Yamaha is normally very good about taking care of their customers and most likely would have corrected it.

I bought it in 06 and was completely unaware of the oil consumption problem until I took it to Arizona. It was out of warranty by the time I realized it was a oil burner. By the time I really started using it it was a year old and out of warranty. It only had about 300miles on it. My 01 Raptor had the same basic design and it used oil too, just not as much. Valves were always adjusted as per the owners manuel. It was just a POS. I have a few friends with 660's and some are ok and some use oil. I have nothing good to say about that motor, in fact it was any good they would still be using it.

The Grizzly and Raptor 660 motors are very similar especially the top end so both have had this problem. I've had two Grizzly 660's and other than using oil after about 2000 miles on the motor they both have been reliable. The fix for me was relatively inexpensive and easy. I Can't complain.

If anyone is looking to purchase a used 660 they should be aware of this problem. Because they run just over 2 quarts of engine oil it doesn't take long to run them low. The first thing that happens is the piston wrist pin will seize and blow out the piston. It normally damages the cylinder walls, bends valves and sometimes the rod. Because all the broken parts fall to the bottom end, low end damage can occur including a broken crankcase.

I'd fix the oil burning problem rather than take a chance on destroying the engine.

You are correct, fixing it is cheaper than letting it destroy itself. That is why I usually carried extra oil and would check it part way into the days ride.

Over all I am very happy with my 700 and for me it was less stressful just to trade it in and let someone else worry about it. Even if it hadn't been an oil burner I would have traded it at around 7000 miles. I have no desire to be 25 or more miles from my truck in the desert and end up walking because of a breakdown. I will trade the 700 when it gets 7 to 8 k on it.

i rode my 03 660 to 10 000 miles then traded her in,it was taking oil but not bad like some others,yamaha really has done its homework with the 700 cuz this motor does not burn any oil,not 1 drop,i'm up to 4500 miles now and am very satisfied

 

[clutch]

Same here Pat. 3700 miles and I havn't added one drop between changes. I really like my 700 and I expect that my wife's 550 will do the same. My 700 does not have power steering and it steers way better than my old 660.

Now they need to step up and make a 800cc or larger engine for 2010.

 

[pat the rat]

surprised you didnt go for ps,its the best feature on the bike,for me the power of the 700 is plenty but if they were to build an 800 or 900,i'd prob buy it,the price would be scary though

 

[grizztracks]

I've rode the 700 several times. The power steering is ok but not a must have for me. The only time you really notice the improvement is when your locked in. It has a little better throttle response than my 660 and starts a lot easier but overall it not a big improvement over the 660. The first time I rode the 700 I was somewhat disappointed. Don't get me wrong, I like the 700 but there was no WOW factor. I really thought Yamaha would have come out with a 770 or 800 twin FI to match the Can-Am. I love Yamaha but after I rode a friends Can- AM....WOW! I hate to admit it to all my BRP buddies but I'm impressed.

For now I'll stick with my 660 and wait for the next Grizz.

Grizztracks just do a search on CanAM forums and see what some people have to say. You will find some totally loyal owners and some people that have had LOTS of problems. Look them up and come to your own conclusion.

I was considering an 800 until I rode the last two winters in Arizona with a guy with a 500 v twin. The first winter he had a two up machine and had two fuel pump failures and three engine failures. Luckily he had a warranty. Last winter he came back with a one person 500 v twin and the engine was fine but the front suspension didn't hold up. Both front shocks failed three different times and the lower A arm trashed itself. It just wore out and got real sloppy. Once again everything was warranteed but at $50 each occurance it was still spendy.

It is not like he is a young punk thrashing on it because he is in his 70's. Abuse is not a factor.

 

[grizztracks]

Hey Clutch, I didn't say I was ready to jump ship. I ride with several Can-am guys (five 650's and one 800) and have seen only minor problems over the last several years. I don't believe everything I read on theses forums but I do believe what I see and so far I see a lot of happy Can-am owners.

I, like many other Yamaha loyalist's have expressed their disappointment with Yamaha's introduction of the 700. Many of us were hopping for a little more. Like I said, I've rode the 700 many times and it hasn't impressed me like the 660 did when it came out. I'm more impressed with the 650 Can-am than I am with the 700.

The bottom line is I'm going to stick with my 660 until Yamaha comes out with an ATV that makes me say WOW again. I hope I don't have to wait to much longer.

I am with you on that one. Unless I get a RZR.

 

[grizztracks]

what? not a rhino sport?

My brother sold his sportsman 500 and bought a 2009 RZR. I'm not a big fan of Polaris atv's but it's a blast to drive. I've never ran any other side x side to compare it to but I'd consider one. The only disadvantage is that your limited to more wide open trails which could be a problem around here.

well boys, to update the oil consumption issue...I read on another site that guys who were using Amsoil in their Grizzlys were having the same issue as me....they said they kept having too top up the oil when using Amsoil, could not keep it in their bikes and once they switched brands , problem solved....I was veryyyyy skeptical but thought what the yek, time for an oil change anyway....so switched to Rotella-Shell synthetic oil in the blue jug and problem solved...have gone out 3 times since and have not needed to add a drop of oil as with the Amsoil I would have had to add atleast a 1/3 of a litre by now....guy told me last time out that he had the same issue with his Polaris and Amsoil.....

 

[grizztracks]

hard to believe. There are a lot of amsoil guys out there that would say your full of it. I've never been a fan of it myself but maybe all oils are not the same. I've always ran Yamalube in the two 660's I've owned and both started using oil at about 2000 miles. I also use it in my sleds but with no issues.

Rotella has been a popular diesel engine oil for years. Maybe I should consider a change. Keep us posted!

I use Amsoil in my sleds with no issues at all...had over 28,000 k on my 98 vmax without touching the engine.....all I know is gone over 100 hard miles since the change and have not had to add a drop so far but will keep ya posted.....
