What kind of damage and or operation am I looking for with the cylinder bore?
Heavy scratching and scuffing or gouging on the piston skirt and cyl bore.
as well as the decompression valve components. I have no idea of what a decompression valve is!
Your bike may not even have one... it is usually next to the spark plug on the head... it is a little valve and it is there to make starting easier.
If I were to remove the piston from the cylinder for cleaning and inspection I would need new rings and the such correct? The old ones cannot be reused?
If the cyl bore and piston is in good shape then the rings should be OK.
But they can also be stuck in their grooves on the piston and letting the compression escape into the crankcase.. they should move freely on the piston.
If they are stuck in their grooves then you should very carefully remove them after soaking the piston in solvent of some kind.. then clean the ring grooves.
Rings break very easily.
Upon inspection of the cylinder I see just some carbon on the piston itself and the cylinder walls do not look overly gouged or heavily scratched.
Carbon on the piston top won't hurt anything.
By the way this motor only has about 4,800 miles on it and the carb is in excellent condition. As I said before it does have automatic choke with I beleive a BVS valve and one other piece I dont recall the name of, is it possible these are not working properly?
4800 miles is more than most peds have on them.
I don't like the automatic choke deal... if the choke is stuck "ON" you will foul plugs all the time.. but it should still at least start with a fresh plug.
I don't know what a "BVS" valve is.
But from what basic things I do know, if the components in the cylinder were working correctly and I have a spark it should fire correct? This is why I removed the carb and sprayed directly into the intake.
Thats right.. if you have compression and spark then a shot of gas or starting fluid should get it to fire and run for a few seconds.
When I originally heard what I beleived was air leaking near the head, I sprayed soapy water all around the head gasket and spark plug threads, and that i when I saw the bubbles around the plug. Now with the longer (Champion) plug in there, there is a spark and there is no air leak that I see or hear, but still nothing.
Well if you are still using the soapy water and still don't hear or see any bubbles.. then I have to say that it will fire and run for a while.. (IF THE PLUG IS A GOOD ONE!)
By "good one" I mean fresh (not used.. or wet.. once a plug has "fouled" .. it is no good) and of the type that will fire on an old moped CDI... that is why I said to use a NGK B7ES.... I KNOW that it will fire on that ignition if the ignition is good.
I don't know what your Champion was intended for.
Yes I know I should get the threads fixed so i can get the corect NGK plug in there, and I have tried but like I said I am having trouble getting tap straight and dont want to screw it up even more.
Take the head to a local Auto parts store that does "machine work" (or motorcycle shop, or lawnmower shop) and ask if they will do it... they will prob charge $10 if you already have the kit.
I do get a blue spark and it will zap me, and I cleaned and sanded all grounds and connections, but is it still possible the CDI is not correct, or is it something that either works or doesnt?
How badly will it "zap" you? It should give your body a big convulsion and send a jolt about all the way up to your shoulder.
And yes... the CDI could be bad... but if it sends a jolt all the way up your arm then it is OK.
Please give me a bit more help on what to look for the motor internals if you can.
I already did above..taking a top end apart on a moped is about a 10 minute job... it is easy... so just do it... the only things to be careful of are covered in my guide... make sure the base gasket isn't torn... make(carefully!) or buy a new one.
Rings in correct position
circlips seated all the way
base gasket in good shape
Isn't "Scooter Therapy" in Milwaukee WI ??
Maybe they are close enough to fix/check this bike if you can't ?
I didn't know what a Champ was ... But I saw one on ebay last night.
