Are they interchangeable ? If I buy an old 1500 can in use parts inside to rebuild my 1600?

No. It's likely a small handful of components are shared but it's an entirely different platform. Not a direct replacement nor could you salvage a 15 to rebuild a 16 or vice versa.

As cheap as these are; you'd probably end up spending more money rebuilding your 1600 then you would buying another 1600! Or even a 1700!

I'd love to find a salvaged 1600 engine with low km cheap to direct swap...

What issues are you having? Just curious.

Good luck! I'm sure you could find a salvage 1600 somewhere.

My compression reading is 115 and 135, apparently that's not great, I can ride it a while but it will inevitably die.... according to the shop mechanic anyways...

There ar 115000 km on it.

Again, like I said, do fret over those compression readings unless you are having a specific problem, such as excessive oil consumption, etc.
Another used engine may be no better, and to overhaul one of these "correctly" can put costs out of reach in a hurry!
The mechanic is putting worry thoughts in your head probably needlessly.

I respectfully disagree with your previous information.

First I would suggest you find another shop to do your compression test as those numbers are very good.
These engine have an automatic compression release (to aid in starting), that does not release until approx. 800rpm.
It is a centrifugal device that is installed on the end of each camshaft, slightly holding the exhaust valve open till
engine starts. Consequently, this also reduces compression readings.

The 15 & 1600, engines share almost all the same parts including the case. Transmissions are identical
including the gear ratios. When changing components such as crankshaft, the entire assembly must be
swapped. (rods, pistons, cylinder. 15 &16s even share the same crank counter balance weights. Heads,
clutch, coolant, and FI systems are also interchangeable.

A complete 1500 E series up (fi injected) engine is a direct replace for a 1600.

Wow that's the most promising thing I've heard so far, I will definitely get another opinion, thank you !!

I also bought a compression tester for 30$, Gonna test it myself properly following the documented kawasaki procedure when I get the bike back.

So for completeness, what should my compression levels be in each cylinder ?

Thx

Due to such wide variances in factory published compression specs, I do not recommend using a compression tester
if searching for a cylinder problem. The published compression ranges are front 50 ~ 85, & rear 110 ~ 180.

I would recommend a cylinder leak down test.

Yes, sorry, hard to get a good screenshot on my phone.
Basically, I dont think the tech that looked at my bike tested it properly as per the kawasaki recommended procedure. I will test it myself.

So the tech called me, he spoke with his buddy who specializes in Kawasaki who told him that compression tests are not really indicative anything on these engines, and that they are solid engines that could last easily upwards of 200,000KM if maintainted properly. He recommended (As Bandit did) a leak down test to ensure that air was not escaping, this would be a better indication of any issues.

I told him since he charged me for the initial compression test, and it was not useful that he should absorb the cost of the leak down test. He agreed, so they are going to do that test next.

This is sounding very promising and I might in fact have nothing wrong with my motor... I sure hope that's the case, it was a very stressful week....

Thanks for all your help and input, I'll let you know the results of the leakdown test once I get them back.
