Jim
Mickle's Yamaha YFZ450R ATV
"I bought this
bike new from Stadium Yamaha in Irving
Texas August of 2009 with the intentions
of not modifying it. Well that didn’t
work and the disease took over.
I ended up with just a pipe and a
programmer at first but that just
wasn’t getting it done. So I
contacted Geoff Mummert with Mummert
Machine and Development (MMAD) out
of El Cajon California. For the engine
work.
I’d like to thank David and
Jason with Quadforce, Garrett with
Fuel Customs, Dave Herron with JD
Performance, and Stadium Yamaha for
all the great go fast parts."
