The grease is the trick thing to do, it worked on my friends 660 Grizzly. Plus we put a dozen holes in the side covers to let it vent some more heat.

i have a few pics of some holes i put into my side panels. i just used 2 in hole cutter on a drill. between that and the grease, i havent sputtered once in a water hole in quite a while!!! next time you go out, just take the side covers off before you go. try that once, with the grease, and check out the differance. also, i have heard that if the valves are to tight, it will sputter too. have you adjusted them yet? i have adjusted mine 3 times, and all 3 times, they were tight!!!
good luck!!

Mich660 is right....the valve adjustment is very important as far as the sputtering goes.

The only other thing i can recommend is that you make sure after you grease the plug that you put the BOOT on right. It only goes on "ONE WAY". You will want to make sure that it is snapped into place too.

After changing my tires to more aggressive, i dont know if it is because you "throw" more water onto the engine or if it is the valves being out of adjustment....but now my bike has NO problems. I also bypassed the limiters too. I can tell you only one thing...the bike is unstoppable now. BUT, time will tell!

This post does nothing to answer your question, but I'll join you in your frustrations.

I stopped in at a local dealer last night after work to talk the Service Manager about some of problems with the Grizz. Of course I only got the patented reply, "I've never heard of that one" in response to every one of my questions. However he did manage something different for the bogging issue, "oh, all machines regardless of make/model will bog/sputter if you have steam rushing into the front of the bike from a mud or water hole". My answer to that is "huh, funny how way back in 83' Honda was able to build the 250 Big Red such that it never once sputtered in water even while I was using it as a swimming platform". That Big Red still starts and runs good to this day after 19 years of outside storage, abuse, maybe 10 oil changes and a set of brake pads.

Some service departments amaze me. After denying any knowledge of existing problems they have the ***** to tell you stuff like "well you know, there's a reason we bill out at $70/hr, because we're highly trained and skilled to work on these machines you know". Yeah ok, 90% of your mechanics are 16 years old, your telling me they know the difference between a spark plug and their own #^%$&#'s. I've gotten the patented "Problem Not Found" or "Could Not Duplicate Problem" or 6 trips to 3 dealers to fix a problem one to many times by auto and ATV service departments for me to have any more than ounces of faith in their self described, so-called "mechanical supremacy".

The only solution as far as I have learned is to find that one mechanic out there who knows his sh^t, or wait till the engineers order a service bulletin describing how to fix the problem. Either way, it sucks. My wife has worked at auto dealerships for 10 years, I hear all the time what a complete joke some service departments can be. Keep up the complaining and calls to the manufacturers, it's the only way to get the companies to take our problems seriously and look into what it takes to permanently fix the problems, issue service bulletins or recalls.

Hay Frogman,
Did you get that problem taking care of that you were having in the mud? I can't exactly remember what it was but it had something to do with bogging down, I think you thought it was due to having heavier tires then the stock ones, I believe in the post you said somthing about the 600 grizzly's doing better then your 660. I am very interested in knowing how you resolved the problem since I am going to be getting the 660 soon.

Edge,

Problem solved. There are a couple of issues that fixed it. One, the valves needed to be adjusted (the right way). Two, bypassing the limiter. It was an easy CHEAP fix and it did the job. I ran the bike "before" the valve job and 90% of the bogging had stopped. After the bypass the other 10% was gone. I have not been able to get it to "duplicate" the bogging since. TRUST ME, i TRY!!!!

I think that one of the intake valves are a little loose now (from me) becuase i have a lil CHIRP in the rev. But, i can tell you, better a little loose than a little tight. I am not talking about LOOSE, just at the upper limits of what the feeler gauge is suppose to read. It seems that the intake valves have a way of becoming tight as hours build on the engine. I also have just the slightest "hickup" in the exhaust during shutdown. Nothing big, and not a backfire. It starts everytime without the choke (i know its HOT out!) even on cool nights. I am starting to do a little of the NIGHT riding and it is alot of fun. Just have to be 5 times more careful not to hit rocks and stumps! [img]i/expressions/face-icon-small-smile.gif[/img]

AND YES, i did answer DanimalFL, i think that the sputtering is caused by inpropper sparkplug boot seal. Add a little Dielectric grease to the plug, and make SURE that the boot is on correctly. I had the exact same problem with mine. If that isnt it, i would swear by the valves being off.
