Can anyone confirm if a KLX250 2012 model exhaust cam will fit the KLX300 1997/98 model.

I understand that KLX models above year 2003 have had the ACR adjusted so the bike will kickstart easier and not be in danger of stripping the kickstart cog.

I have made a rash purchase of a 2012 model cam with a view to fitting it to the KLX300 and now have concerns it may not fit when it arrives.
