Sharksawyer 03-19-2010, 12:41 PM RPM codes: 3000 - Throttle Position Sensor 7000 - EXUP valve 8000 - Fuel sensor Sounds like you need to clean your EXUP valve and set it up and also adjust your TPS. What year is your bike?

If not, you'll need to remove, clean and apply a little grease. The cables should not be tight. They should be a little loose or they will bind and cause the 7000 error. Mark 99 R1 belo85 03-20-2010, 04:33 PM i read that the cables need like max of 1.5mm play thats y i tightend tham Sharksawyer 03-20-2010, 08:57 PM You are correct about the free play but it doesn't really tell you how hard to push on them to get 1.5 mm. I've adjusted mine to 1.5 mm and found they were too tight and had to loosen them to get the error to go away. There's also a procedure in the maint. manual that will help you set up the correct position but that's also a little vague. Basically, you need to adjust the cables so the tabs line up with the 3.5 mm hole. You then need to start the bike, turn it off and then turn the key back on to initialize the motor. Check the tab positions, rinse and repeat if they are not right.
