I just purchased a '17 YZ250F. I have been looking around for pipe, fuel and mapping recommendations to mostly no avail. For some reason the '17 owners are either not mapping or keeping their info close to the chest. I have found some maps for the '16 model, but due to the differences in engine power characteristics, I figure those maps are not worth considering at this time. Although I may try some in the future.
What I will do, with the collective knowledge of Vital, in my second post, collect all of the data that you post & put it there.That way it will be easily accessible to peeps looking for either hop up suggestions or maps or even what fuel to use.
If you would when you respond, please post:
A.) Rider classification
B.) Fuel
C.) Pipe
D.) Engine Mods
E.) Other mods of note (gearing, powerflow, filter, etc.).
F.) Map
G. Comments
A big thanks goes out to Donnie at Morgantown Powersports and RJ at Beaver Creek Cycles
