Question:

i have valve touble on motorcycle ?

when riding my motorcycle valves start knocking i took to a mechanic and they did not resolve problem. i have baby ed my motorcycle. dint know what to do at this point and time.

Answer:

Charlie, I know it is hard to transfer a sound into a word. but valves don't knock, they clack. So if it isn't a clack it isn't a valve issue. Sadly you haven't helped us to diagnose the issue by giving the make and model of your bike. That would really be a help. I would like to help you further so if you hit my avatar you will find my email address for direct contact so I can help you further if you can't find out more help form the other guys.
A lot of times you will not hear a valve problem, They tend to tighten up with age not loosen. On sign of a valve out of adjustment is if bike is hard to start when cold. knocking could be loose timing chain, timing chain tension-er needs attention.,Could also be worn drive chain. It will make a popping sound when its stretched out. Some front brake calipers will make a knocking sound, its the pads rattling around between calipers and rotors.
Make, model, year? Knocking from the valve train? If it is knocking or ticking from the valves, your valves are out of adjustment. You need to remove the inspection caps over the valve adjusters. Most valves will have one of three types; 1. Hydrolic. 2. Bolt adjustable. 3. Shim. Take a valve lash reading to see if they are off. Ticking can also be caused by a lack of oil to the head. Make sure your engine oil level is where it is supposed to be.
