So last summer I had a 203 cam installed and my bike dynoed by HD dealer. Since then upon startup the orange service engine light and sometimes the red check engine light come after initially starting the bike, only for about a minute. They also sometimes flash on and off on hard decel and throttle. No noticeable exhaust popping or anything. Wondering if this is normal after a tune or if I should take it back and have them look at it or go to someone else?
Thanks.

 

Since it's almost a year from when the work was done, I don't think the dealer would take any responsibility for a problem. They'll claim anything could've happened in that time, and it could have.
Before you take it anywhere else, check for codes. When the check engine light comes on it means the bike threw a code. Find out what they are and get back to us.
