My friend I go riding with, has a 2004 grizzly, we were in some fairly deep water
but did not swamp it. The next ride we went on it was hesitating at around 50 to
65 Km/hr, but fine before and after those speeds. It was kind of sputtering. Any
reasons why? Any suggestions would be appreciated!!

 

hi i have a 1999 yamaha warrior and today it was also hesatating so i looked at the air boxlid and the screws were loose. so make sure the screws are tight and nothing is loose on the air filter lid. (under the seat)

 

Hey Bagz....thanks alot! I will tell my buddy!! Thanks again!

 

Tell your freind to drain his gas and fill with fresh stuff. I had the same problem and there was water in my gas. It only takes a small amount. My bike ( a 600 Grizz , did the same thing, and it only happened at around 50-60 ). Adding a little gas line antifreeze to dry up the water might also work.

 

tell him to change his oil too, its possible some water got in his engine, that can cause it to bog

 

Thanks for the info hellboy2004 & Rider1169 !! I called and passed along your info already.
He took it to the dealership today for the first tune up. They figured it might be part
of breaking the Grizzly in, ex. some things may need re-alignment(cylender). It only has
430km on it. He's gonna have them change the oil and gas now that you mentioned it!!
Thanks again the help is much appreciated! If the Grizzly's not working........
I'm not playing in the mud with my LT250R!

Thanks!
