Hi Guys,

I have been an NSR250 owner since 2005 when I picked up an RK5 MC18 (Which is back home in Toronto). I just recently bought a 1991 MC21 SE to ride here in Dubai as well.

I was curious if there were any issues fitting and MC28 rear head to the MC21 front cylinder? I know the engine differences were minor and it has basicaly remained unchanged since the MC21 came into production , but do remember reading that there was a small compression increase over the years.

Is anything else required besides the new HRC radiator hose (from Tyga) and the shorter plug and coresdponding cap? Will I need to adjust the carb at all? I am plannign to fit Tyga pipes and end cans at the same time as well.

Thanks in advance guys!

Ryan
