No compression I mean, it has no compression unless u plug the carb with your finger, my uncle has an OS. The head will need removed to determine the problem. The last thing I tried was a compression check which yielded low normal compression on all cylinders except cylinder 1 which yielded no compression after 2 seperate checks. Tighten the packing nut on the toilet shutoff valve one-eighth turn clockwise to try to seal a leak around the nut. To have zero compression you have to have valves stuck open or a hole in the piston. Wet test on #2 did not make a change. Next, remove the old compression sleeve and nut. All valves touched the pistons, 4 marks on each piston and marks on each valve. Not to state the obvious here, but if you adjusted the valves and now have no compression, then you tightened them too much. BMW/mini garage have said no compression in cylinder 1, however, the timing is in spec. If you turn the nut counterclockwise looking down on top of the valve, the leak will get drastically worse. My first though was that I had blown a piston or a valve, but fortunatly is was "only" the gasket. Compression flattens wrinkles and prevents new ones forming, and silicone creates a microclimate between it and skin, drawing up moisture to plumpen. Marathon runners have been sporting compression socks for several years. Removed header and carb. On Saturday I participated in an organized trail run. How to Free a Stuck Exhaust Valve by Brian Hiser. Those pieces from the valve seat may enter the intake and/or exhaust manifolds as the result of normal air turbulence. But after checking #5 again, there was no denying it. The spark is ok but with a compression test they could hardly get 5psi. Rotated the shaft 'til the compression stroke was coming up, then put 30 weight oil in the cylinder to see if it'd leak out overnight, figuring it'd indicate a stuck or broken ring, but had all the oil still in there the next morning. No compression indicates a stuck valve correct? The hydraulic valves are supposed to be auto-adjusting right? I opened the valve cover, and turning over the engine the valves seem to go in and out, but I don't get any compression on the test.

Problems in other systems may cause this same symptom as well: a leaking fuel injector, bad ignition timing, bad cylinder compression, bad oxygen sensor, or other problems. In addition to a normal compression test, a cylinder leak down test should be performed, that will help localize where the compression is being lost. The intake air is pushed back out the inlet valve on the compression stroke so no compression takes place. In a single cylinder engine it can be as simple as a stuck valve. if no change its possible valve stuck,bent,or burnt or hole in piston.

A leaking valve can cause enough compression leakage to impede starting, then if you DO get it started, everything is happening so much faster that the compression doesn't have time to completely leak out on each stroke, and the bike will still run - but only for a while, the blow-by will erode the seats more and more as time goes on, and make it worse and worse until it's a disaster.
