125cc 4stroke, please help!!!! oil leak/exhaust gasket/cylinder
 

There has been oil leaking. I got a new gasket seal (seemed to be leaking out of that area, still leaking. I've cleaned the carb. Do I need to replace the seal in the cylinder head (looks like it could be leaking from there too...!!!

Please help!!!

What can I do, can I replace that seal? How to a take off the cap to take apart the cylinder???

Also, could I be losing horsepower because of that oil leaking??? It also putters like it is running out of gas. When I rev on it hard it won't let me rev the whole way-is there a rev regulator? How can I fix this problem so that its getting the correct amount of power???

Any help is very appreciated!!

post up some pics so we could tell where the leak is specifically if leaking between head and cylinder yes you are losing compression and power but if leak is only at cam chain side may just need tightening also check valve lash clearances may be too tight
