This is all sort of related to Juneaudave's thread, so I'll jump in here one more time and then I'll butt out.
I know it won't matter to you because you won't be climbing a hill or riding a trail and stall the engine, but the K1 and K2 also have primary kickstart which eliminates the need to find neutral before kicking the engine over
If I am ever climbing a hill or riding a trail or stuck at a traffic light and stall the engine on my SL350 K0, I will not even think about finding neutral so that I can use the kick starter. I will just pull in the clutch lever and hit the magic button for the E-start. As you know, it will work just fine with the bike in gear, because it spins the crankshaft directly via the sprag clutch. The bike doesn't care if it is in neutral. Coincidentally, guess what the USPS brought today from Partzilla? Yep -- brand new OEM springs, caps and rollers for my sprag clutch!
Dave, on the other hand, doesn't need to worry about rebuilding an E-starter or a sprag clutch, so there is that advantage!
And you won't be looking for the nearly unobtanium left switch (horn only, made entirely of plastic except for the tiny little board with contact on it and the spring for the button) that most sellers think they can ask from $125 to over $200 for.
No, but the K0 RH switch pod is unusual because it has the magic button for the previously mentioned E-start, AND it uses a black kill switch knob -- not the run of the mill red one. (I have a new repop one that is OK by me, but I probably paid too much for it. I also have the original one, but that is another story.)
Carbs are smaller (24mm) and the camshaft is different too, for more torque and a flatter powerband as well as a lower redline along with it.
And here, Dave has the advantage with his K1, if he is out doing whoop-dee-doo's and landing hard. He has no vacuum slides to slam shut from inertia and bog the engine. If he is racing, nobody will crash into him from behind. I understand this was the reason for going to the other carbs on the K1/K2 models.
And you won't have to search for another nearly unobtanium part, that silly little twist-lock toolbox cap that didn't lock very well and is missing from nearly every one you see.
No, but I have a K0 toolbox which I have blasted and painted, and it is complete with its hinged door. It is identical to the CL350 box, so it is easy to find. Ironically, it will be almost completely hidden behind the large plastic side cover that is nearly impossible to find. I
do have a pair of the repop side covers from Randy Marbles, as well as the badges for them, but I hate to admit what I paid for them. I bought them early because I was afraid he would quit selling them by the time I am actually ready to use them.
Someday I may start a build thread on my SL350 K0 bike, and I apologize to Juneaudave for interrupting this good thread he has going. Maybe though, some people will enjoy reading about some of the differences between the models that we have discussed here.
For comparison, here is what the K0 should look like in gold:
