I recently owned a 2003 rancher and about a month before i traded it in on my new foreman, I welded an alminum pipe to the stock pipe just for reassurance. On the first ride i noticed it was puffing a litte bit of blue smoke after I'd let off the gas. It wasn't running very hot or anything. Does anyone else have an exhaust snorkel and is so have u had any trouble? I'd like to put one on my foreman, but i don't want to hurt anything. Any help would be greatly appreciated. Thanks
