Iv been following these forums for awhile and am finally in a pickle and need advice. So the story so far. Last week I did a oil change and noticed I had oil sepage from the camshaft seal so I bought some silicone sealant pulled the cover off and put some sealant on there and patched it up. During this service I also cleaned and re-oiled my air filter and put some carby cleaning additive in my fuel. Bike ran well the next day on the way to work with the minor exeption of a short cluggyness in response from my engine kinda the same feeling u get when ur outta fuel and have to switch to reserve, anyway that only happened for a min and I thought nothing of it. The next day I had to travel to the city, no problem on the way however when I got there and was looking for parking I noticed my temp gauge was a lot higher then normal didn't get in the red tho and it cooled down when I had air goin through the radiator, parked it and it was fine on The way home. The next day too work it was fine but on the way is where the real issue started, I took off from a set of lights and the bike once again became unresponsive I was driving full throttle but compression was kicking in and out so didn't get much speed for full throttle even on the highway I was doin less then 100 with full throttle and it was a real struggle to get home. When I got home I started thinking what it could be, my first idea was a cylinder wasn't fireing so bought some plugs fitted them and tried it out, same problem
next check coils for spark both spark fine. Next I noticed oil sepage in the same spot so cleaned all the sealant off refitted tried again, same problem next I removed the air filter and tried again same problem so now here I am thinking its a head gasket or its the fuel additive I added. Any suggestions on what the problem could be would be great also if any1 has a copy of the base ex-250 workshop manual that would help heaps the zzr suppliment just doesnt have enough information
