Whats wrong with my bike!!??

Recommended Posts

I put a new hot rods stroker crank in my 2009 honda crf450r and when i put it back together we had no spark, after days we figured out that when my power commander 5 is pluged in we loose spark, as soon as its unplugged it starts up but runs like crap. bought a new pc5 and still the same problem. and power commander says it has nothing to do with spark, which is true. ***??

it obviously has something to with spark, you can adjust the ignition timing(spark) pretty sure you need an auto tuner to tune while its running, youre supposed to flash the bike while its shut down, then test your changes.
