I do remember reading somewhere an article that the 03 was going to be restricted more than the 02, 01, 00 etc. Wish I could remember the source, but I can't. Sorry! Cache is right though, just de-restrict it if you wish.Suzuki.Org has a post of a guy who claims his 2003 Busa is top-end limited to 177 miles an hour. Any of you 2003 owners agree? If this is true, would this keep you from buying a new 'Busa? Would you buy used instead? Opinions please.
4th is not restricted on the 02. just 5th and 6th are restricted on the '02. easy enough to bypass also. don't let a piece of paper get you mad. specially if your gonna race it.It does make a difference to me because I plan on racing my '03 Busa at Maxton as well as my car. IF this is true I am 'damn' mad because I could have purchased a new '02 for a couple hundred less AND NOWHERE in Suzuki's literature does it say that the '03s are any different (computer wise) than the '02s. My understanding is that not only 6th gear is restricted but 5th and 4th are RPM limited as well.
From the post over at Suzukhayabusa.org, he states that 4th gear was/is limited to 10.2K RPM (and I guess if that is true then 5th is limited to 10.2K likewise). So even with a TRE, it doesn't help ....This was planned and announced way back in 2000. The limit is to eventually go to 165. This is nothing at all to be surprised about.
With that said, the TRE probably still works this year. I have not seen it confirmed yet, but I doubt they covered that loophole since the agreement also stated that de-restrictors would be sold for race-only applications.
On another note, if anyone is trading ECUs, selling one, parting a wrecked bike, etc., let me know. I am looking for any year ECU at a fair price (like $50 or less) for some long planned R&D (preferably 2001+ and one from 2002+).
