I need a help about cam notches count for bandit 250CC (GJ77A), GSX250 manual says it's 16 but it's not fit to mine. Please help..
If anyone have GSF250 1995 40HP manual I can't find all over the internet..

Same motor, different carbs/CDI so that'd work.
The GSX-R250RR (and variants) all run the same top end too.
From memory they're rather easy to line up and you may need to consider stepping away from the bike

When I align EX no "3" at 12 clock and IN no "2" 12 clock I get 22 cam pins from EX to IN and cam position marks align to gasket but GSX250F Service manual says it must be 16 that is too short in mine.

I still can't find any service manual for GSX-R250RR either. Can you please tell me timing marks & cam pins if you remember.
