there's alot of chatter about this bulletin. and maybe some misinformation?! there are no parts required, it's an adjustment. there is talk about free oil and $100 gift certificates.if your sled is running lean on oil does it "burn down" or could it run for 1-2000 miles putting premature wear on the motor? I for one am not too happy with a gift certificate in place of a potential bad motor!I've owned over 20 cats since 1969 and it would take alot to make me change brands but this one really bothers me.How about keeping the gifts and extending the warranty?!
