if you look at a post i responded to awhile ago you'll see a pic. i posted of my drain plug where it had worn away. it deos stop some of the noise for sure and will make the transmission chain last alot longer lol.

 

Wow, warranty item at 100 miles, chalk one up for the POO people!!

 

we also purchased a 2007 last year. we thought it would be the 4 wheeler of our dreams. after riding it the first 50 miles we noticed exactly the same clunking. we brought it back to the dealer they put in shim kits and said it was all fixed. sent us on our way and said it was fine. thanks polaris for the 2007 pos of our dreams. its not fixed and never will be. we now have to pay off something we dont want since we bought the only year that does this and there is no way to fix it.

 

this is the not the only year that makes noises as both the 06 and 08' made the sounds.
