Written by Monty (some time well in the past) TPS Adjustment (Missfire and Under Powered?) If you think things are not right, before taking your carburettors apart check the Throttle Position Sensor, I always thought mine was ok as factory set and never gave it a thought, all you need is a multimeter, basic instructions are here. There are 3 pins in the unit; measure the resistance in k ohms across the 2 outside pins, a reading of between 3 to 6 k ohms should be seen. Make a note of what it says, get a calculator and work out what 76% of that figure is. i.e., outside pin resistance 5.23 k ohms ----76% of =3.97(these are my figures, swap them for your own) Hold the throttle fully open and measure between the top and middle pin, the reading should be 3.97(your figure), if it is not slacken the 2 screws and move till the figure is the same as what you worked out. Your ignition timing should now be correct; you may have to remove the tank to access the pins better. From the 4 sets of carbs I've seen, the TPS has always been mounted in the centre of the slots, which for quickness sake means they will all run but may possibly not be exact. |

not really understanding what all this means but have measured mine start 05.1 75% is 3.825 and i have 3.9 me thinks near enough but dont know what effect the 0.075 equates too ... anyone know?? Edited by ac@39, Apr 19 2013, 04:31 PM.

When you say slacken the screws and adjust until correct what exactly am i adjusting? The depth the screew is in or out? The angle of the TPS unit? Im about to get the multi meter out and do it now Never mind, worked it out. Didn't notice the pivot when i looked in the dark last night. Got it spot on now. Still runs like crap with that beowolf exhaust on it. I opened up the can to repack it and it was completely empty!!! It now sound spot on with the baffle in now i have repacked it.

Thanks, very efficient. Presumably the first reading is not affected by adjustment? |

You are correct, the first reading is the whole resistance of the resistor, should be around 5-6k ohms |
