Engine swap?

Just a curious thought and I got nothing from the search bar, has anyone swapped a more modern engine into a z1000 frame? 

How "more modern" are you thinking ? the below link is a current build with a later water cooled Z1000 motor

Engine swaps are very common.
The most popular being Suzuki GSXR/BANDIT 1100/1200 motors which have been done to death and also Yamaha FJR engines .
Non of which i particularly like despite having done similar myself..

 

Which option was the simplest swap? I was thinking as modern as possible. I’m not planning to do this just curious if it had been done and how simple or complicated it could be

I’m thinking of the fuel injected water cooled possibilities

Most things are possible if you have the fab skills or budget - generally later motors are smaller so don’t require “major surgery”

Not sure if this counts, My Frankenstein GPZ1100 B1 had a pretty standard motor with only porting, valve springs, Exhaust and Carbies. On the dyno it had a reasonable 95RWHp.

Combined with 215Kg (wet, half tank of fuel) it was pretty good but I always wondered what a GPZ1100 1983 bucket head motor would be like. I eventually found a parts bike for a reasonable price, the bores were damaged a bit by standing too long so a I bought an as new barrel replaced the pistons/ rings with NEW OEM Std. Valves were replaced because the previous owner had modified 1981 valves (which have a longer stem). All else looked good, just checked etc.

The engine fitted beautifully, and to my suprise it performed better than I imagined. It is not only a lot faster it is better all round. (I stored the older motor still in excellent condition).

The only problem was, the previous owner removed the positive neutral bearings which makes it hard to find neutral, nothing major just annoying.

For a Suzuki GSXR/BANDIT 1100/1200 motor swap you have to fab some additional brackets.

 
 
 
 
 
 
 
 

Very impressive fabrication. Welds especially.
