Here is a free web based jetting program for your Rotax. Have Fun!

So a couple tricks. All you have to do is keep your web browser open all day and you can use the software without a web connection.

The program is a great starting point and I did my by best to have jetting suggestions that are actual worth trying. I think its still a little rich on the main jet so you can go 1-2 jets leaner and feel safe.

It’s going to be a work in progress, so if you have any suggestions or issues send me a quick email. Email Blake
