Hi I've already posted about the poor running I'm experiencing with my 2001 xvs650 I've tested the TPS and wiring and refitted and set up the TPS and I still have the same issues it also does the missfiting and putting engine light on when revving it when stationary any ideas?

I've tested the throttle position sensor and all seems well with it and the associated wiring. I'll maybe need to try the battery disconnect trick see what happens!

Hi I've got a 2001 xvs650 dragster it starts and runs fine but once your driving it seems to accelerate fine up through the gears but as soon as you make it work and it gets up to about 70mph it starts miss firing and the engine management light comes on. When you stop bike the engine light flashes 4 times then a pause followed by another 4 flashes and just continues until you switch the ignition off any ideas?
