Cr80 gearbox oil 300ml short after ride.

Just dropped the gear oil out and its 300ml short of the 600ml thats ment to be in there.

Crank seal had been replaced with a genuine honda one and ive just had the case off and its fine and still firmly in place.

When running the bike will literally shit black oil everywhere out the pipe.

Any ideas?

Did a compression test with throttle open and this was the result.

Valve timing is bang on (both valves are closed on TDC on compression stroke.

Timing is spot on (points just opening on the F mark of flywheel on compression stroke)

Spark plug is sparking when held against the head and bike is kicked over.

A little fuel straight down the cylinder, kick bike over and nothing.

If anyone has any ideas then im all ears.

Looking for something with the same image quality, 10 bit colour, 4k 60fps and optical zoom and im really struggling! Sony A6400 seem to be close.

I really like the RX100 Vii but no 60fps and only 8 bit.

Recommendations please!

Does anyone own both the rx100 vii and the pocket 3??

I have a pocket 3 and find the image quality amazing but im after something with a bit of zoom.

How do the 2 stack up against each other in terms of image quality?

Still struggling with this cb125s.

Plug is sparking when held against the head, but the spark is orange, bright but orange.

Thimble of fuel straight down the cylinder and nothing.

Timing is bang on.

I really can't see why it wont pop or fire with fuel directly in the cylinder???

Piston and rings are new, valves are lapped.

Surly it has to be rhat the spark isn't strong enough right??

This is how far off the mark it is when the points break contact on the F mark of the flywheel on compression stroke.

What are the causes for it being so far off the mark?

I have seen other videos on you tube where people's heels are worn a lot more than mine yet they're still perfectly on the mark.

So im pretty sure the bikes not getting fuel, i will do the easy start down the cylinder soon.

Bike is all together correctly and timing and valve clearance is perfect, valves are lapped and not leaking, opening and closing as they should.

As plug is dry im leaning towards no fuel issue but as stated in last post, carb has been thoroughly cleaned including all passageways. It was stripped and submerged in white vinegar for half hour then washed and blasted out with carb cleaner and air.

So what could cause a carb to fail???

Piston and rings have been replaced, bore is good and new gaskets have been fitted so I can't see it being a compression issue although I will check compression at some point.
