Hi,i am trying to get information and experiences regarding the yamaha xt 660 fueling issues .I was wandering what year models are affected and if it is the odd bike or all bikes that are affected.my bike is an 09 and it suffers the same fueling issues at low speeds /rpm.i have contacted several dealers some are helpful and some are scornful of forums etc.i have also contacted Yamaha UK and they also have no information ref ecu remaps,or replacements.i shall now be going down the keV mod route ,but would appreciate any reply of owners regarding these issues.

Have a read of this thread regarding the surging issues and what can be done to improve things...
