Apex 2006

[mikeyrules]

Anyone seen an Apex 2006 showing a spark plug in the dash,machine runs great at idle,but cuts out at roughly 4000 rpm.
Only once i saw error code 01.
Can this be the throttle sensor(tors)
Help....its snowing here...

Are you sure it was a spark plug and not a shock?

This link is to the code chart. I am not sure what the difference is between fault code and diagnostic code. Diagnostic code 1 is for the TPS.

Apex error 01

Turned out to be the drive shaft bearing being worn and touching the speed sensor.All is good now.Thanks totally yamaha...!

Good thing you caught it now and fixed it before you would have been broke down on the trail somewhere.

Replacing this bearing is a common maintenance issue. I replaced mine last year when I replaced my track (along with all of the driveshaft & jackshaft bearings). None of the bearings had failed but I just replaced them all for peace of mind.
