750 and 500K0 are 8mm holes in the stays, no rubbers or spacers. Just a bolt and washer ;)

The ones on his 500 K1 have the smaller holes but the new front guard I got is for a 750 and I am told it's identical to the 500 apart from the stays have larger holes for the spacers and washers. As he's sprinting it he says I can basically swap over whatever I want, within reason. Typical DK bike though ..fannied about with, supposed 3k original miles but no inner in the speedo cable !
At weekend stayed overnight & saw his CB750K1 he got from Summerbud with Lesters on it (bargain) and he just got a Kwak '71 H1 500 project that looks another bargain to me .. included paintwork done by Dream Machine and lots of work done and then abandoned. I suspect hes going to sprint the Kwak and the CB500K1 is going to go down in the queue and he seems to be getting more and more peed with it. It 500K1 refuses to fire on one centre cylinder. Had a quick look myself , checked the coils and caps and plug and all fine. Squirted some Easystart down suspect cyl carb and it coughed into firing a bit and heated the pipe so suspect carburation but he's adamant he's ultrasonicaly cleaned them. Problem is, No filters on it and horrid sidewinder pipes plus he's running off the tank as he got it from DK. Mucky watery petrolly liquid peeing out of suspect cyl silencer. Said if he can't sort it he can try my carbs, once I have cleaned them out. Also he's borrowing a compression tester and told him to make sure no valves are stuck / tappets set correctly. Any other ideas you 500 gurus?

Yea that's what I thought. Think I would have at least had the top end off though to inspect it. He did take the cam cover off and it was pristine.
K2-K6:
Does sound like the carbs, you could try running a fine bore tube from the vacuum gauge port on that carb to an open pot of petrol (only small in size) to see if it'll suck fuel and so bypass that carb's jets to see if it'll run on all four.

a couple of months ago I stripped my carbs to do a cruzimage part overhaul,
if you disturb the slides,its important to check all slides open at the same time,I had similar symptoms and took me ages
to getting it running well again
I mounted the bank of carbs in/on a workmate type bench,then using the throttle stop screw and a torch,I lowered all the slides,
shine the light through the carb (s) and chech they open together,I expect you will find is lagging,
hope it helps,of course the motor runs ok ish above 2,000 rpm with iffy carbs.
but sounds like a bag of spanners close to tickover
