But you have to consider:
Is the stroke the same between the Flash and Kangaroo?
Which crank are you going to use - are they interchangeable? Are the crank pins the same size as each other?
Im just asking these in my POV, and because I dont own either of the 2 engines
Yes, those are same stroke, both using R7 conrod.
For sure I will use Kangaroo crank (14mm) because the conrod pin on crank worn out, so the glow plug on F 21 burnt always. So give it a try to move the 9 ports P/S to Kangaroo.
