Looking for some info on how to change the oil on my bike as I cant seem to work it out. There is no fill port. Its a Jap Import to UK RMX 250. The frame is 1995 but I know its had its engine changed.
Here are some pics of the engine. I am trying to work out what year its from also
The engine number is
J1134 - 104006
Just wanna change the oil but am completely baffled
