Riding my 22’ Matryx 850 and noticed the last 2-3 rides a slight bog at the lower end when modulating the throttle in technical terrain. Seems to maybe be getting slightly worse the last ride out. Got pretty unrideable today. Tried swapping plugs, no help. Started throwing codes 4 - 51 - 1 then 10 - 51 -1 had to call it a day. Local dealer pulled the P codes. Any ideas? I do have a Munster Finger Throttle, but i dont think the TSS bypass would cause these codes ?
