Well, I can guarantee you that Redline is a high priced oil and a very high quality oil. I have an 09 with over 300 hours without a rebuild and it starts and runs like new. Like I said before I don't buy used dirtbikes because of most people spend thousands on a bike and use a petroleum based oil which does not protect well in these motors no matter how often it's changed. Spend some time reading real facts on the base stock oil groups and additive packages. Most people have an opinion based on some sort of emotional attachment or marketing hype. Better yet send some virgin samples and have them tested.
So you are trying to say that petroleum based oils can't protect these engines? What tests are you going off of because that sounds a lot like all of the marketing hype I've seen. Like I said, I know redline is a good oil, but maxima
and amsoil have tested just as well if not better in every type of oil test I have seen, and I can get both of these for less money than the redline. Believe it or not, your bike will not blow up if you run a different type of oil.
I've never had anybody come back to me with a problem with a used bike I sold them. I had an 04 YZ250F I raced my last year in B class and first 2 years in A class on dino oil. I put in a new piston and sold it to a friend of mine and he put 200 hours on it racing B class without touching it (running Rotella T). He sold it to another guy that I see from time to time and he still hasn't touched it. I can assure you there is nothing wrong with my used bikes, just sold my old practice bike after only 4 hours on craigslist.
Unless I see an hour meter, I take any amount of run time with a grain of salt. For example you said a year ago your 09 had over 400 hours on it: http://www.thumperta...ost__p__9512138
Personally, I would rather buy a used bike from a guy with an hour meter that says he changed the oil every 2 hours and rebuilt the engine every 50 hours (with receipts and the used parts to show it) than the guy that brags about the bike having hundreds of hours on it without touching the motor. There are still things that wear out regardless of what oil you are running.
