Compression Test 0,0,0,0?

[Guest]

So last year my 750, the #3 cylinder was getting washed down with fuel and spitting the fuel+ oil mix out the exhaust pipe.
Since then
1. replaced the piston rings and
1a.fuel needle valves on 2+3 just in case
2.cleaned/ lapped the valves also.
3. put it back together with some new gaskets although cylinder base gasket doesn't have the fire rings. (is this the problem?)
4. made sure the timing marks were in order and adjusted the valves with feeler gauges if remember correctly somewhere btwn .02-.04. Recharged the battery and tried to start but no go.
5.Checked the compression, no readings at all (zero) on all 4 cylinders?, spark is there.

going to recheck the valve adjustment or is there a bigger issue going on???
take it to a shop or sell it on ebay as a project bike?

I'm no guru but I'd revisit the valve timing.

It's tough to get zeroes. Perhaps the cam chain is not indexed right and you are trying to compress with open valves.

Are you holding the throttle wide open, but even then you should get something. Make sure the compression tester has the one way schrader valve in it. If it's missing, pressure will never build up. Leak down tester hoses don't have them.

Try another compression gauge? You should get some reading even if the valve timing is out (if it was out far enough to give a true zero reading there would more than likely be valves hitting pistons).

Try another compression gauge?

Bingo.... Exactly what I was going to suggest.

OP, try putting your finger over the open hole and crank it over.
