Frequently Asked Questions Forum

OK guys, need your help with this.. My jetting data is in WinPEP, so I can't just post the whole thing.

I want to create a DR Jetting guide.  Here's the deal... If your bike is running good (lasts longer than a week on one plug and doesn't incinerate topends), then please PM me with your jetting.  I want to keep this to ONE POST!  Please DO NOT POST TO THIS THREAD! I want this to be a one-stop-shop for accurate, tested jetting specs.  Here's the data from the bikes I have now. Please PM me with the same data from your bikes and I will add it to this repository.  

Thanks!  Skip.
