regarding the 87.5 XT that seemed to be in production for what, six months - January to August 87 ?, the factory manuals that covered the tiny differences - such as the different distributor and ECU..were the differences covered in the factory manuals for 1987 XT or was it a tiny scrap of supplement of twenty pages or so?
I have an electronic version of section 2, but I am of the generation that needs to thumb through smelly old paper and oil, grubby marks etc to be able to absorb the info ( short term anyway:) ) Being electronic data storage I need to nail it down in the glove box with a compact reader rather than have it mixed with other useless to me memory sticks.
Unsure if the eversion spells out the differences between 87.5 and 87 ...or, was there even an 87 AND an 87.5 ?
Did the XT just go from the 86 "three plug ECU, flapper AFM, separate knock control box, vac can on dizzy" to the 87.5 model "4 plug ECU, hotwire MAF, optical no can dizzy with knock control and spark control being the fourth plug of the ECU" and then August 87 shift to the 1988 model with small changes to the 4 plug ECU and optical distributor" ?
So, if that just thought of idea is correct, any 1987 factory manual will contain all needed to be known about the unit we all seem to call " the 87.5" ??
