More bad news.

It looks like it is seating but apparently it is not as air still blows past valve. :side:

Bump........is it time for a head job?

Well as long as you've got it off already :laugh:

Always time for one
Sometimes the bike needs one too.

THE CAMERA IS SMALLER THAN A 9-VOLT BATTERY only costs $23 on Ebay
- it is a color camera
- it has audio as well
- resolution is only 380 tv lines (TVL) but shouldn't matter if you're up close

On the more expensive side, $150 for this one, it is smaller than a peephole you find in the front door of a house, to help you figure out if the valve seats are burned (= leaking valve seat) or maybe avoid pulling the head again is this guy
- 4000 (thousand) TVL -- very very high resolution, super clear images
- 15mm in diameter
- it is a color camera
- 180 degrees view angle.....wow. Only $150.

The generic peephole mounted in doors is on the left in this picture, the camera's on the right -- tiny

This one's a Sony, gotta be good, and only $53, look how tiny it is, smaller than an RCA jack in the picture there
- 420 TVL of resolution

I've been debating getting one or 2 of these to see if it makes my life easier, I have a kz900 right now with a compression issue, I alos have a Honda Nighthawk that might have thrown a small-end bearing and was gonna put a small camera down there to see if the piston drops or is there 'play' as I rotate the crank.....

stuff like that. Lots of reasons to want a tiny camera inside sometimes.

Search on "mini camera" on ebay, lots of 'em.

If you burned a valve seat (running lean? is your exhaust pipe blueing on that low-compression bore? maybe it ran too hot and scorched that exhaust valve seat; are you running individual pod filters and a less-restrictive pipe and did you re-jet for that?)


I gotta stop procrastinating, get me a tiny camera like the one my dentist uses to scare me into getting more fillings and other works. Lots of reasons to have a tiny camera in the engine sometimes.

They're cheap too, the first time a mini camera saves you from a tear-down of the motor, it has paid for itself.

23 dollars, I could put that in the air cleaner box and watch the carbonators for that price.

:woohoo: :woohoo: :woohoo: :woohoo: :woohoo:

I don't have it off yet. I just have the valve cover off and was trying to spray carbon cleaner in the valve from the exhaust port to see if something was in there :silly: . lol

it should hold liquid in the ports but be careful as it will probably end up in your oil.

Might possibly be a valve spring issue.

Good Fortune!

Easier and cheaper than camera...

1) Remove exhaust.
2) Remove spark plugs
3) Ignition plate cover off.
4) Using larger crank nut (not smaller), rotate crank where cam lobe is not pressing against shim thus opening valve.
5) Small pen light down spark plug hole into chamber.
6) Look into exhaust port...

See light...?
Yup, bent valve or spring or.... regardless, head has to come off for further inspection/valve job.

OMR I tried the light thing and did not see any light however I know there is a blowing past it.

I pulled the head off and thing look grimy to me. I posted the pictured in order from 1-4 on both heads and the pistons. As you can see in the last picture it looks like the might be a little piece of something holding that valve open ever so slightly. However it looks like the head might need some work. What do you think?
