I'm getting these resistance readings from my TPS. The constant resistance (blue and black wire) reads 4.6 ohms. The variable resistance (yellow and black wire) reads .21 Ohms closed throttle and 3.5 Ohms full open throttle. The full open throttle is the only one out according to the manual. I still need to check the input and output voltage but I need to get some smaller probes mine are to big and blunt to get in there, could I use a paper clip or something to poke in the wire harness and then touch the probes to them or would that give me an inaccurate reading? Here is why I came to think that my TPS may be bad. Since I did a rebuild on my bike it's had an intermittent idle problem. Feels like the throttle is stuck at times, It runs perfect for a while and then it will act up for a while. I let off the gas and it stays at a high RPM like the throttle is stuck partially open. If I pull in the clutch it stays idling very high and won't come down, the only way I can get it down is to let the clutch out a little till the rpms come down and then pull the clutch lever back in. It will stay idling fine then. I originally thought it was just the throttle sticking but I've pretty much ruled that out. Cleaned everything and even while its idling high I can sit there and play with the throttle all I want and it wont idle back down plus I can hear the slide closing. Also if the throttle was stuck open it would idle back up after I got the rpm's down by using the clutch. I've gone around all the places were there could be air leaks with propane and found no changes in RPM, plus it's seems to be more then just a hanging idle from being lean. Usually in that case it will slowly idle its self down, this won't. And I was thinking since it's intermittent that it's an electrical problem. Like i said it will run perfect for a while and start acting up for a awhile and then be perfect again, temperature off the engine had no effect either. So I decided to check the TPS yesterday. First thing I did was just unplug it and ride. It seems much leaner at idle with it unplugged, have to leave the choke on for quite a while to keep it running and it has a slight hanging idle, that does come down. I think the fuel air mixture screw just got turned into much but I'm going to wait till my Merge fuel screw gets here before I do anything else cause I can't tell if I'm turning the screw or not with the crappy short little homemade screw driver I made to fit in there. With it unplugged I haven't had that stuck throttle felling yet but it's been so intermittent it's hard to say. The TPS is expensive so I want to make sure I actually need it and if I do is there any reason I just can't order a TPS from Sudco for this particular carb, isn't the Yamaha one just an over priced repackaged Keihin one anyway.
