tps and throttle stop screw 1200 limited fi

[finkeel]

Still have had no luck on finding a definitive procedure for throttle stop screw adjustment. It's below the throttle arm , left side , facing fwd. Here is my thought on this thing. Back out the idle screw on the center of the air box , back the throttle stop screw out "left side" bring the TPS setting to 485 then set the throttle stop screw with the feeler gauge in place to the TPS, then reset idle. Does this make any sense ? There has got to be a way to adjust it! Or maybe someone with a good running LTD 1200 could take a measurement of it and get me in the ballpark. I would certainly welcome some input on this pesky little screw I cant get my head around!!!
Thank you Bruce

The throttle adjustment is in the middle of the engine at the rear. You can get to it from the right side of the bike. This adjusts the RPM of the engine. The adjustment for balancing the left/right cylinder banks is on the right side under the CFI cover. You cannot balance front/rear cylinders on each side because it is fuel injected.

The screw on the left side of the throttle arm assembly is used to adjust the TPS only after the initial setting has been done. For the TPS adjustment, take a small nut, I think one that is for a 1/8" bolt and measure it, should be close. You adjust the screw on the throttle arm to rest up against the throttle arm. Do not adjust this screw so the throttle arm moves. Put the nut between the throttle arm and screw, and check the reading. It should be close to what is in the manual.

TPS initial setting of say 0.495 VDC is with the throttle fully closed, and is adjusted by turning the TPS in place.

Do you have the manuals for your bike?

Hope this helps. Cheers

Yes I have the books and they are vague on how to adjust this screw. They don't tell you the initial setting. They assume the screw has never been moved, mine has. So i think your agreeing with me, with throttle fully closed and the TPS set at 0.485 ( the middle of the tolerance ) bring the throttle stop in contact with the arm and then place the 2.9 mm feeler gauge in place and recheck the tps setting. Are we on the same page??
A sincere Thanks for your help,, If any one else has any input please feel free to let me know.
Thanks Brrce

That's exactly what I had to do as well. Now that you mention it, there is no reference to the initial setup with regards to RPM, balancing of the cylinder banks as this affects where the throttle linkage is positioned.

I've adjusted mine, but still get too much fuel on a cold start. There's a fellow in Saskatchewan who adjusted the TPS on his bike to just below the lower spec reading at about 0.45 and apparently it works well with no excess gas on start.
