2007 Yamaha Phazer ignition setup
Posted: Thu Jan 13, 2011 12:04 pm
We are trying to get our 2007 Phazer (2 cylinder 4 stroke 500cc engine) running on a MicroSquirt after our tune was messed up. We have proper fuel settings (from the old tune) but cannot seem to get it to start. During cranking it will occasionally backfire through the throttle body, leading us to believe our timing is off. We have old tunes from previous years which we assume the machine ran on. The motor either cranks without firing or backfires through the throttle body depending on the tune. I assume this would point to a timing issue. Does anyone have suggestions as to what would needs to be changed with the settings to get this thing up and running? The machine has a cam and crank sensor and coil on plug ignition. Thank you very much, any and all help is greatly appreciated!
