diference 5K7 and 2H9

[Ronajon]

i'm about to have a look at a XS1100 Sport (5K7). before i actually am going to buy it, are there mechnical differences between the 5k7 and 2h9, are parts interchangable like cables, engine and carb part, etc ?
i have seen the cosmetic differences between the 5k7 and 2h9, tank, seat, rims, side covers. Are there any more ?

Hey Ron,

You still haven't posted/edited your profile to reflect where you are, but I'm going to assume it's somewhere in Europe, since those Vin prefixes are both Euro models.

According to the Vin#/ser# thread.. http://www.xs11.com/forum/showthread.php?t=396
The 2H9 is the 78E Standard equivalent, and the 5K7 is the 81 Sport/Special model.

There are lots of differences that won't swap for spare parts between them, carb parts....jets, vac. slides, floats;, The Ignition system/boxes are totally different, 4RO for the 81 with built in/programmed Centrifugal Advance curve so it only uses a mechanical Vac. Adv. pot, the 78 uses 2H7 series TCI, and has mechanical Cent. Adv weights/parts as well as Vac. Adv. Pot. The 78E rear wheel is 17", the Sport should be 16" but who knows, perhaps some of the EURO guys will chime in. Also, I think the 5K7 uses REARSETs footpegs and shifter lever design?

The Sport or 5k7 was basically a European version of a Special. It has a 17" rear wheel not the 16" used on Specials and normal position for the pegs not rearsets. A lot of stuff will interchange, but on the other hand a lot won't, problem being a 2h9 was the first of the models and the sport the last. Wouldn't be my choice of models to interchange parts with. Like T.C says different carb set up, ignition etc.
