Hey all
In addition to my 1985 K100RT, i've got myself a K100 / 2 - Model, DEC 1997 vin decoded production date. Bike was sitting for the last 6 years but after cleaning the injectors and replacing the battery started and idled like a champ with just two turns of the starter motor. 10.000 km only on the engine. Problem is that has no registration papers since the owned had died and his kids declined the heritage due to their personal reasons.
Tank has a minor pine size hole underneath so its leaking and the fuel sender is a block of solid heavy corrosion.
Anyway, I m seriously thinking of swapping my 110.000 km current engine with the new one.
Problem is I cannot find info about this K100/2 specific model regarding final drive transmission ratios etc.
So, to the point.
1. Is engine swap a direct swap? I mean complete with gear box and final drive, arm, etc?
2. In a first inspection I noticed that a plastic flat "tray" underneath the wiring loom under the tank is missing. Is this normal for this model?
3. Are there any differences between two bikes in terms of FI computer under the seat and the ECU or they are identical directly swappable?
4. Are the footrests compatible for mounting on the same holes? Are there differences in height of the drivers footpegs height between these two models?
I would really like your thoughts on this swap. My current running old engine is fully reconditioned with 4 hole new injectors , valve clearance set, Tb's tuned, clutch assembly new, Gearbox, Clutch, seals and RMS replaced, Oil/water pump rebuilt, new Bosch Fuel Pump, splines properly lubed and in great shape.
Thank you!
