step 1:
create a new gas tank that lets you access the carbs easily with the tank off, put a fan in front of the bike pointing at the radiator. turn the fan on high.
step 2: warm the bike up. check where the idle is and make a mental note. with the bike running and the tank off you should be able to access the mix screws on the carbs. with the bike running, turn each screw a quarter turn one direction. did the idle go up or down? if it went up, keep turning in that direction until the idle reaches the highest. if it went down, turn the screw in the other direction. if you get to either end of the mix screw (wont go in any more, wont go out anymore), make a paper note about which way, and what pilot screw you were in.
step 3: try another pilot jet. pick a direction, its safer to go richer instead of leaner first. try that jet, repeat step 2 with that pilot jet. dont touch the idle nob this entire time or you will throw off your results. can you get it to idle higher with that pilot jet? then that pilot jet is better. keep going that direction until it stops getting better. did it get worse with that pilot jet? go the other direction. pick the jet that gave the highest idle after tuning the mix screw for that jet. if your idle is getting too high (higher than 4k rpm) you can start turning it down, just remember that all the numbers will be skewed. remember to take that into consideration when making and reading your notes.
step 4: after you have chosen the correct pilot jet, adjust your idle nob down to 1500rpm.
---------
step 5: put in the largest main jet you have.
step 6: put the tank on, get the bike ready to ride, warm it up and take it for a ride. while you ride make mental notes about the way it performs with wide open throttle at max rpm in a specific gear. always use the same gear. use a higher gear. if you have an area where you can take it to redline in 5th or 6th gear, thats ideal because you will notice the difference in power the most. just do it where you wont get a ticket (where its legal and you arent going to die) take a few passes to be sure its consistent. dont worry if it struggles at mid-range rpm or half throttle at this point only focus on wide open max rpm power here.
step 7: when you get back to the garage, write down what you thought of the power with that jet on paper. put in a smaller jet and try step 6 again. continue until the top end stops getting better or if it starts getting worse. pick the jet that felt the best. (most power) if two jets feel the same, pick the larger of the two.
---------
step 8: if there is any stuttering, clunkyness or roughness during an rpm climb from wide open throttle through the rpm range of 5 to 9k rpm, your fuel curve isnt right. the needle height adjusts the needle curve. if it feels jittery like the engine wants to cut out usually that means its too rich, so drop the needle down. feeling lean is a little bit harder, just doesnt have as much power but not as clunky as a rich condition
doing plug checks will tell you if you are lean or rich at any time.
