Great, I’m about to swap the engine out of my Blaster into a 2004 YFZ450, you don’t mention the idle? Usually you have to add a idle adjustment to the carb? I’m swapping in a CR85 flat side carb (same 28mm size as the blaster carb)
No need to do anything with the idle, it can remain factory, it just adjust with a big straight screw on top of it that giant apparatus on top of the carb
