[QUOTE="ionbeam, post: 446991, member: 277"] There is nothing that can be set from the diAG mode, only from the Co mode. In the diAG mode you can toggle things like the coils, headlight relay, fan relay, etc; you can view fault history and reset the codes but you can not set anything, not even the TPS. Did the check engine light come on? Are there any stored codes at diAG 61? For the engine to run WOT the butterflies in the TBs must be wide open, this the only way it can run full throttle. Either your throttle tube (handlebar) is stuck or the pulley between the TBs is stuck. Even if the TPS were stuck at 100% it would need the throttle plates to be wide open to supply the air. With the ignition off try snapping the throttle open/closed and see how it feels and listen for mechanical noise. ????? [/QUOTE]
