To Drill Or Not To Drill?

[nick crisp]

Interesting. I always had the idea that with just a can swap, you don't need to do owt else, and that you balanced airbox mods with carb jetting changes and the like. Got a tri-oval on mine (Delkevic) though, and I swear it throws the carbs out of balance. Don't know how that could be, but I'm ever more suspicious about it. The Scorpion oval can I had on the last one went on before Ivanising (so no carb or airbox mods to start with) and ran just fine.


Try it without drilling first, see how it runs.
