Those are crush washers. Oil, brake lines or cylinder head.... my guess cylinder head. Under every stud nut is a crush washer.

I don't think so. That would be in the oil pan. There is only three part in the starter area. Starter, intermediate gear and the starter clutch/gear. I'd pull the clutch gear and inspect it. Backfire or any reason the engine would be forced backward could break that clutch, although that's what it's there to prevent."I'm sorry, I didn't mean to upset you when I called you stupid.

Broken cylinder. Already taken care of.
I have another problem...
when I was putting back engine sprocket I removed rear wheel so I could put a chain arround engine shaft. When I mounted rear wheel back I set up chain slack but I have noticed that slack is changing as I am spinning wheel. The wheel itself is spinning like it should half of revolution and other half is spinning significatly harder. When I measured position of rear sprocket compared to rear fork, it really is moving 3 milimeters forward and backward.
I am sure I have returned everything like it was and I did everything by the book... Supported wheel and all that. Also I tightened it to 80Nm because when i tried 100 like it is stated in manual, wheel was barely spinning.
Any ideas?

That would be a bearing or spacer issue. You need to figure that out or risk alignment and chain issues that won't be pretty."I'm sorry, I didn't mean to upset you when I called you stupid. I thought you already knew..."

And finally, last problem has appeared. I cant start the bike. 😊
Fuel valve is ok
Carburatores should be fine (cleaned 3 months ago)
Spark plugs get wet from fuel
Spark plugs throw sparks
Compression is ok
Engine timing is correct
Last time when tried to start the bike i reved it (with a starter motor) for like 20 seconds and it produced a loud bang from exhaust. Really loud. Ocasionally it starts for a second but that is rare, and one time it even reved to 3000 rpm and just died.
Is it possible that sparks get thrown at wrong time. I had almost identical symptoms on M5 few years ago and it was malfunctioned cam position sensor. I dont know is something similar possible on Katana.Last edited by Gabriel Dark; 04-19-2017, 09:40 AM.

Backfire or afterfire.....if the coil input power were on the wrong coil it could backfire ( threw the carbs). Plug wire location could also cause it. After fire would be a lean carb issue, loading the exhaust with fuel vapor then igniting."I'm sorry, I didn't mean to upset you when I called you stupid. I thought you already knew..."

I am quite sure that coils are connected like they should be. I didnt remove them from harness and left coil goes on first and fourth cylinder and right coil powers second and third cylinder.
I am not 100% sure but I think it was afterfire on the exhaust.
I can clean carbs again but if that dont help I am completely out of ideas.

Is it normal for spark plug cables to have arround 5 kiloohm resistance?
That is actually resistance of spark plug connector itself. Anyway, is that normal resistance?
I am also measuring over 20 megaohm (probably infinite) resistance on one of the ignition coils (spark plug side). Is it even possible to throw a spark with such a resistance (because I have spark)?
The primary side of both ignitio coils is 2.8 ohms and signal generator is 165 ohms so that should be ok.
