| | Posted : 12 Dec 2023 - 12:13 Post title : TPS? | | | Morning! Can someone shed some light on the throttle position sensor(TPS). I've read a few discussions about how to adjust it and looks like a real P.I.T.A.
The spec's I've seen are .58, .59, and .60. Tuneecu on my bike is showing.68. Is it worth the trouble to make the adjustment? What am I gaining by
removing the throttle body to achieve a number that stops my brain form wondering if I should do this or not. 
Thanks for reading

That is a high reading, .6v is the number to aim for and yes it is fiddly to do but can be done without removing the assembly. You will need a long 6 or 8mm ( can't recall which atm) open ended spanner and a longish flat blade screwdriver to lever the switch either way once it has been loosened. I chose a cheap spanner from my tools and welded an extension on it, patience is required. Obviously the fuel tank needs to come off so you can approach from the top.

I can not identify any symptoms.Motor pulls hard in all gears idles at 950ish, and fires right up. Some after burn bangs, but that may be all.. I'm not sure what I should be experiencing. All I have is a number in tuneeuc and now your input that the number is out of spec and should be addressed. Appreciate the feed back and instruction, I built my 69 so I am mechanically inclined, but must admit electronic influenced motors intimidate me....

(Re: HansomeRob) | | | Oddly enough.....scrolling through some other post I came across "checking TPS " by "daz" He's listed detailed information about the specs in tuneecu. According to his experience it appears my TPS is in the correct range. This is good news and explains why I was unable to identify any symptoms, because I wasn't having any!
