I could have soldered up a DJ jet and drilled it out, but I already had the Mikuni jet, so I thought I'd experiment and see what happened. All seat of the pants stuff though, so who knows.
I also neglected to add that the pipe comprises a FMF Powerbomb header and Megacycle muffler and tailpipe.
The DJ 150 is the same as a Mikuni 142 I thought?
A DJ 155 would be about right with a bit of altitude and/or not much air box cutting.
I was running a larger pilot (+2) and pilot air (+1) too.
