Jetting Calculator Program/Spreadsheet

[brademan76]

Anyone ever tried jetting calculator or similar? Seems pretty handy! As I don't know where to start with jetting my PWK for my 250 ATK, I may go utilize it, unless anyone here might have some jetting advice?


He's got lots of other "calculators" as well for the data driven individuals

I have not ever used a jetting calculator, but it does seem like it could be very handy. There are quite a lot of variables though, with porting being the one that is going to be the biggest and most unpredictable variable to calculate based on.

Are there any forums or groups for this engine model / bike? Surely someone has put a PWK on this model previously.

I have found very little discussion of the bike online. There is a Facebook group for ATK bikes but the other models are far and away more owned and discussed. I'll figure it out.

Spend the money on a wideband O2 sensor, I live near the equator and I had no idea where to start with jetting all of my bikes as most of the jetting advice comes from the US and that doesn't work at all where I live
