The easiest way to setup the RF is start the bike and warm to normal engine temperature. Hold the RF with the adjustments on the right so you have one row away from you and the other row close to you. In this view the lower left adjustment is the low to mid RPM set point. I start by setting this at 1800 RPM. If you have a tach just hold the motor to 1800 then adjust the pot until the light switches from the middle light to the one furthest to the left. Once you've done that move over one pot to the right. This is the Mid to high RPM adjustment. I set that to 4500 RPM to start. Do the same as before only the light will switch from the far right light to the middle light. Now hold the motor to about 1700 RPM and adjust the top left pot clockwise for the smoothest engine running or until the engine stops gaining RPM. Be careful to watch the light as only the far left light should be on while adjusting. If it switches to the middle light you will need to back off on the throttle some. Once you have done the adjustment, start to go counterclockwise until the motor begins to slow just alittle and stop there. Now raise the RPM to 4000 and the middle light should be on. Follow the same adjustment procedure on the mid fuel adjustment pot. It is the middle pot on the top row. I leave the high RPM fuel adjustment off to start with(counterclockwise all the way). Now move to the lower row far right pot, this is the accelerator pump adjustment. Give the engine a good quick throttle snap, paying attension to how it rev's up. If it rev's quick and clean do nothing. If it pops back or stumbles turn the pot clockwise 1/4 turn and try again. If that fixes it adjust the pot down (counterclockwise) until the pop/stumble comes back. Then go clockwise just alittle to get rid of the pop/stumble. You want the least amount of accelerator pump you can without a stumble. Take it for a ride and see how it runs. What you want is the fuel pots to be as far counterclockwise as you can with a good clean running bike.
The high rpm is the hardest to adjust because you need high engine speed to tell. It adjust the same as the others but it doesn't adjust well at no load. So just go ride hard and at high RPM and try adding some fuel, if it gets better try alittle more. You want to add the least amount to achieve a smooth running bike.
I didn't type this but I used it to tune mine
Hope this helps you.
