HELP!! My Bike Doesn't Start :(

[Lincoln97]

I want to get the bike started as i love bikes and just looking at it is doing my head in i dont know whats wrong with it the guy said head cylinder but what can be wrong with it

[Guest Richzx6r]

If you can get hold of the guy who said that ask him categorically what is wrong with the cylinder head as to my fairly trained eye there looks on the surface to be nothing amiss with it but maybe he knows the history of the bike?

Bike has NO compression from sound of first video .

To do a quick test

Remove spark plug

Make sure plug lead is out of the way .

Place your thumb or finger over the spark plug hole to seal the hole and press the starter .

It should be forced off by the cylinder pressure

You will need to get a cylinder pressure tester to get an Accurate reading though.

Looks like engine has been stripped at some point .

Ie your 'collector 'you bought from has removed parts from engjne ie piston or valves

I did ask him to do this in a previous post but not sure if he did or not, I'm going to bet this bike is a lemon

According to another post on here there are parts of the engine missing.

To me that has had a new barrel on it as rest of engine is dull chipped etc but barrell section is shiny .

So at a guess . potentially

No gaskets or damaged gaskets

Piston rings not correct

Valve clearances far too excessive

Missing engine internals
