done this to a members bike the other week there and could not remember which pins on the plug to use as photofukit has removed the image so we had to go crawling the net.
insert the wire with the ignition OFF.
once the wire is in place turn the ignition on and start the bike and let it warm up. look at the clocks and where the temp usually is should now show -00
loosen the bolt/s enough on the BOTTOM sensor so the TPS is still tight'ish but able to move.
move the TPS back fourth so the line 'just' moves to the bottom like _00. you need to adjust the idle screw to keep the revs steady on pre K7 bikes. wait 10s or so then slowly nudge the TPS till the line 'just' moves back in the middle -00 then 'nip up' one of the bolts. you might need to keep adjusting the tickover screw as you make adjustments to the TPS.
test the rpm at which the line moves to the top by turning the throttle. the line should move to the top at around just off idle. basically you want the line to move as the slack is taken up on the cables of the throttle and the throttle starts to turn about 1mm or the revs are a gnats hair off idle.
once done tighten bolt/s then check again to make sure the line has not moved and that the throttle position is the same then check again turning the bike bars from side to side to make sure that again the line does not move.
enjoy
top tip: use the handle end of a screwdriver to 'tap' the TPS bolt lug to move it tiny amounts. also if you put a bit of thick card between the throttle grip and the housing it makes the throttle less sensitive and can keep the revs at a certain position, remove the card once done.
