Crossplane crank for novelty purposes
On a 4-cyl 2-stroke? It would be terrible for vibration.
Crossplane crank for novelty purposes?
I don't really want to go flat plane like a 4 cyl 4 stroke as that will be firing 2x cylinders at same time. I'm not sure why Yamaha did it on their R1?
I think there is a couple different theories in the motorcycle world to do with big bang or screamer firing order setups. The big bang, giving more time for the tyre to relax and regain grip between combustion cycles. Where as a screamer the combustion cycles are evenly spaced and provide more consistent power.Not sure how it would affect a jetboat,big bang firing order might be hard on splines ?
