Yesterday while riding my Grizz, it started to idle at half throttle. I was going maybe 50mph and let off of the throttle and it kept going on its own at about 30mph. I shut it off to see what was going on. I opened up my air box to check it out and I realized that part of that filter that acts as a gasket between the air box and air filter was gone! I couldn't find it anywhere, and I am sure that it was sucked into the engine. Finally after playing with the carb a little it released and then the Grizz started to idle o.k. I rode it the rest of the day without any problems. Is there anything that I should do? Does something like this cause any damage to the piston or cylinder? Any help would be appreciated.
Thanks

 

any suggestions?

 

?!?!?!?!?!

If sand or dirt will screw up an engine, i am SURE that the foamrubber gasket that seals the airfiliter will! Did you find it? It couldnt have went to far.... Have you taken the carb apart? I dont know how that thing would make it to the piston....unless the gas disolved it. If that is even possibe, i would say that you better start cleaning your fuel supply out.

There has to be someone on this FORUM with more info than me....
