I just purchased a new 2012 YZ450F coming off a 1996 YZ250. I havn't rode in a few years except on occasion here and there with my consistent friends that ride consistently. Anyways, let's cut to the chase. I totally underestimated the power of a 4 stroke, and believe me, its crazy especially with this fuel injected megaton beast! I have been reading on here, a specific thread about "Owner EFI & Timing Map Database" thread. My question is... Is there a way using a programmer to tune this bike dramatically DOWN for the time being UNTIL I can get used to this unreal torgue beast? Like I said, I havn't consistently rode in a few years and my first test ride was exciting, but I feel like its going to give me more than I can handle at a track or on a hardcore woods track. I have even thought about immediately selling this bike and going to a YZ250F BUT obviously I am going to get it handed to me as far as money goes. So if I can TUNE this bike WAY down for the TIME being until I get the feel for this 4 stroke, it would be much more worth it because I could tune it back up in the future instead of having to get a 250F and then turn around and go get a 450F again.. I don't want to be criticized for my actions here. Just looking for some solutions to help that won't cost me thousands upon thousands of dollars.. Thanks.. Any response would be greatly appreciated... And FYI..This is my very first post..and plan on getting many tips from this awesome well informed site.
