not quite positive how to make adjustments with the FI models, but the monitoring and data gathering should be the same... you will want to measure from both the front and rear cylinders. I am assuming that your muzzy's have the O2 bungs welded in both front and rear pipes. Follow the instructions on warming up and calibrating the LM-1 unit before performing the actual tests. i start with the front cylinder, then measure at 1/4 throttle, half throttle, and WOT. read the numbers on the display of the LM-1 during each of the tests (it also stores the data on the device which you can import into the software via a laptop). perform the test the same way on the rear cylinder. ideally, you want the readings to be between 12.5 and 13.1. from this point, on the carbed models you can make whatever jet / mixture changes are needed....but not sure on the FI model.... enjoy!
ps...there will be sometimes where you might have a slight miss / hesitation throughout the throttle range that will not be resolved. ive always been told to tune for the throttle range you most often ride in... ie, if you ride WOT 90% of the time, tune for WOT and learn to live with a slight miss at half throttle......
pps... another important item while tuning.... perform these tests while the engine is under load (not on jackstands or in neutral....) the readings will be very different when not under a load.
