:rolleyes: a good while back i posted about getting a stealth exhaust muffler for my Yamaha grizz.well by shear stupidity ,i gave it a bad rap and said how it fouled plugs and lost performance.after all the aggrevation of sending back to Cabelas and bad mouthing the product,i find it was my fault to begin with. for some strange reason,i have had the choke on when i thought that position was off.running with the choke on ,will definately screw things up.i didnot want anyone to refrain from getting one because of what i said,sorry \:\(
