Firing order
Does anyone know if you can change the firing order on an IL4 so that two pistons fire together at the same time thus having the effect of a double vtwin or a v4. Do they call this a big bang engine?
Just curious!

Re: Firing order
Change your crank so that the pistons are working in balanced pairs, change your cams so that the valves open at the new time, and then buy a bespoke ignition system for your bike.......
And if you've got fuel injection get that sorted out as well. |

Re: Firing order
I think you'd have to change the crank as well, never heard of anyone doing this, it would be interesting

Re: Firing order
Or, if you were following Performance Bikes "Project Big Bang" (Started in january issue of this year" then it would go:
Snap Crackle BANG! They were messing around to get a big bang firing order from a normal engine, but their first attempt blew up (Cam bucket shattered and the engine at itself) |
