Backfire through intake during cranking
#11
The first Power Vision I did was on a Dyna with 204 cams. Would start fine cold, but soon as warmed up was hard to start. You had to crack the throttle to get it to start. Leaned the cranking fuel and no more issue. I do it on all the maps I do. It is almost a necessity if you have cams or free flowing exhaust. It doesn't help much on stock bikes, but doesn't seem to hurt anything. they also seem to start better if you just hit the start button soon as you turn on the bike. I only wait if engine is cold for the light to go out.

Been getting this issue more frequently. Sometimes during cranking, cold or hot doesn't matter, my 103 will backfire through the intake. It usually starts up just fine after that. I've had off and on cranking issues with this bike since I got it. Sometimes it fires up in 1 second, other times it will take 3-4 seconds of cranking. Totally random, I never know what it's going to do when I hit the starter.
I'm thinking the backfiring may be related to my battery being a little weak because it tends to happen more when it seems that the battery is struggling to turn the motor.
Before you start thinking lean mixture, don't...I've actually added 10% more fuel during cranking with my PV to see if it would help the random starting issues. So far it hasn't.
