    1988 CBR250R with MC22 Engine
    Hey guys, I recently purchased a bike off of one of the members here, it has -

    MC22 Engine
    MC19 cams, rotor, pickups & ignition

    I have some questions regarding the maintenance, do I just use the MC22 spec oil and filter + air filter + fuel filter and lines when working on the bike or do some things stay MC19 spec?

    Thanks for any help :)

    What is the frame? MC19 or MC22?

    Use the chassis as a basis. If the motor is definitely an MC22, then use MC22 parts/specs except where things have been changed. Most of that list is electrical so when checking those components, use MC19 information.

    Frame is 1988 CBR250r with a MC22 motor installed with MC19 cams among the other stuff I listed. So should I be using MC22 spec stuff for everything? I think I read about some differences between the fuel filters between the 2 but there's not really any information I could find about MC22s sitting in a single R frame.

    Welcome.
    They are both MC-14 engines, so what things being different are you worried about?
    Are you running 19 or 22 carbs (19's used a fuel pump) and which airbox?

    I'm waiting for the previous owner to send me the full details of the bike atm but I believe apart from the parts I listed, the bike has MC19 parts.

    As Murdo indicated, there is very little difference between the MC19 and MC22 engines.
    From a maintenance perspective, I would just use the MC22 stuff.
    If you download the CBR250 service manual it has information for all variants.

    Cheers
    Peter.
