Hi idont believe that you have piston to valve problems as the valves would simply bend, this would then reduce your compression and your m/c would not run correctly .
wot you may be suffering from is just large valve clearance or worn camshaft and or valve gear,however this must be investigated further
hope this is of help ian

Im still breaking in my bike,,why is there a ticking sound in the engine while running?

All the parts in your engine are wearing in. Part of the 600 mile check up involves adjusting the valves and the cam chain tensioner (if it is not self adjusting). Chances are the valves are wearing in, the gap is too wide, and just need to be adjusted back to the correct clearance. Worst case scenario the cam chain tensioner has failed.

Motorcycle knock and blow-by (4 stroke)

hi,might be able to help,a compression test would be a good start,however,if you already have the engine apart,replace the rings anyway,if the engine has been overheated the rings although they look ok will have lost their tension and therefore their ability to hold sufficent pressure against the cylinder walls,therefore allowing blowby,or compression leakage,the other area i would look is the condition of the valve seals and seats,both intake and exhaust,if the engine has been overheated,the seals may have cracked or become weak,whenever i have my race bike apart with the head off i always relap the valves(just a light cut)and this ensures a good seal through the head etc,hope all this helps...cheers ian

What is the intake and exhaust adjustments on the 2003 klx 300 with feeler gauge

Intake is .002 and exhaust is .004. When setting remember that the proper way to adjust the valves on this model is the 'go-no-go' method. For intake, .002 will go and .004 will not. For exhaust, .004 will go, .006 will not.

Hyosung RX125 I have had an oil leak ever since I dismantled the engine last month. There was a slight knocking, however I went out on it last weekend regardless. The bike started to lose power after 2...

Is your bike making blue/blueish smoke while running? From the stuff you told us, it is either worn piston rings or worn valve seats, but i would personaly bet it's the valves, because the knocking sounds would be the valves being severely out of adjustment, leading to a huge loss of power and many noises. Hope i helped you :)

If you are not a mechanic, take it to a shop before you completly destroy your cylinder or case. You most likely have a broken ring, bad valve or loose ring clip, but either way, the reason it is worse at the lower end is because that is where you are putting the most stress on the engine. could try using higher octane fuel, OR...your running the engine to lean. In any case, you should seek professional help with the issue, because running it with it knocking WILL end in an expensive repair.

Problem with the valve/front brakes on 2001 Kawasaki 300

sounds like that the piston o-rings are warn out. replace them on the master cylinder and get your self a 12 inch tube and a small glass jar loosen the bleeder valve put the tube on the bleeder valve and the other end in the jar put brake fluid in the jar and put it in the reservoir don't let ether run out and keep moving the brake lever it will get the air out of the lines quicker, repeat this for the other side
