I read the oil pump posts & keep thinking about NOT touching my pump. I haven't checked my oil ratio but I'm using the "normal" amount of oil I've always used in my Cat's. My sled has 1200 miles on it without any problems on it, I have not checked for piston scuff (which I hate to say is normal on any two stroke) nor will I. I'm not a stupid person & take excellent care of my toy's but it seems to me that if the sled is running fine now, why would a bulletin about possible problems change anything? Is it just me or are some people over reacting to the bulletins? I don't doubt that there are sleds out there with the wrong pump arm length but please explain to me how a sled that has run flawless for 1200 miles will seize the engine b/c there is a new bulletin out? Why would I run pre-mix now when I haven't in the past & what will this possibly prevent? Flame away but please realize this post is not meant to attack people who are concerned about the oil consumption, I think it's good to check your sled & have a solid understanding of what it uses in fuel & oil. I just don't understand how people can say the letter came too late & are concerned that they're sled may self destruct after reading the letter even though they have a bunch of miles on it with NO engine problems.
