    Good day friends!

    Thread starter told: "My voltmeter reads 4.4 volts at a throttle closed position and 1.1 volts at full open"
    I have the same issue. TPS operates in "other direction".
    Why it is so?
    Have you solved it?

    Because the repair manual is wrong, and you should measure the voltage between the black and blue cables.

    Greetings all,
    for sure the bike will run without the TPS, but I would recommend you keep it attached and adjusted, especially if you ride on the road.

    I went to the effort of fitting the TPS to my FCRs during the install and so didn't really get to appreciate the difference it makes. Until during one of the many strip-downs to re-jet, I forgot to plug the sensor back into the loom. Starting was more difficult as a result and small throttle opening sensitivity was pants! I was convinced I'd cocked up the jetting or left something open. Nope. When I pulled off the tank and spotted the problem, I replaced the plug and tried it immediately: it completely cured the problems!

    Maybe it's not so noticeable off road, Ken? Maybe you've got the throttle wide open all the time? I don't know, but that's my tuppence-worth on the subject.

    OK, I'll ask! Ken, what's the AP mod we should know about please? Occasionally one of mine doesn't perform perfectly, so if it's to improve function, I'm all ears...

    Thanks.

    Cheers... Paul
