Hello all! I am looking for some help and suggestions as always! I have an 09 Mastiff with dual runner intake, big radius pipes, .585 cam and about 3200 miles on her. The cam is the most recent upgrade, roughly 500 miles ago? I did an oil change the weekend prior and took the bike out for a spin and it still ran like her normal raped ape self!! Then the following weekend I took the bike for a spin and roughly 3 minutes from the house the motor lost 95% of her power, no abnormal lights on the speedo, no abnormal lights on the ehc...not that I have them memorized, the motor still increased RPM's but could barely move the bike, exhaust note changed and we slowly limped home. I looked over everything and jumped out as abnormal to me, I recranked it and it sounded normal, roughly 2-3 minutes of running and the exhaust note changed again...I wasn't riding but I am sure the power would have dumped again. Before I tear into anything I just wanted to poll the community and see if anyone has some suggestions on where to start? I am leaning towards an ignition issue, something is telling it to go to a reduced power mode like engine overheat or something? As always, thanks for being a great community willing to help!!!
