Need Help!!
I have a 97 RK with a screaming eagle air flow kit and Samson slip on mufflers and I'm looking to re-jet my carb and was wondering what you would recommend??

Hi Edster 69,
On the stock CV carb I would recommend starting with a 180 main jet first. You may want to get a jet kit with a variety of jets so you can fine tune the carb. I would also recommend setting the c-clip on the center location and add washers as needed for fine tuning as well. Depending on how your spark plugs look and your gas mileage you may want to make adjustments on either jet sizes and c-clip locations on the needle. I usually go with the 185 and go leaner from there but nowadays everyone is more concerned with gas mileage so you may want to just start with that 180 jet and see what the plugs look like. Make sure they run a nice tan color for the best air/fuel mixture and no deceleration popping. I hope this information helps and let me know if you need any other hints on the adjustments.
Thank you,
JR

Samson gave you good info and is correct with the jetting. I don't think you will find a needle with a c-clip and notches in your carb unless someone has changed it from stock. The best needle for the street is the '88 sporty needle. With todays fuel we like to see the plugs colored from white to a very,very light tan. To get todays fuel to turn the plug tan like in the old days you will be rich and giving up around 5-7 MPG. If the plugs are white just make sure they aren't "blistering", that shows a lean condition. Be sure to drill out the idle mixture screw and set it out 2-2 1/2 turns to start, and set the idle RPM's at 950-1,000 RPM's. Do not modify or change the spring or drill the slide for the street as this will also hurt mileage without any real street performance gains. Hope this helps.

Probably won't get much better advice than this.
