OKay so my knowledge with motorbikes are very low.
Anyways my 89 Gixxer 250 has a low compression problem.
So i took it to the shops and i find out.
Dry tested it and all cylinders come out in the 50's and wet test only brought it up 10ish Psi's.
Valve clearances are good.
Spark Plugs are fouled with carbon.
I think we need to do a leak test to see which parts are causing it but right now i really think its the piston rings.
What do you guys at KB think?
