I have the 2009 Kawasaki Vulcan 900 custom. I bought it last May of 2009 with Cobra speedster slashdowns. I liked the sound of bike better than with the stock pipe. I finally decided to add the BAK & Power Commander 3 to get the best performance out of the bike. I had the dealer do all the work. A few hours later and a bill of $236.00, I took the bike out for a ride. I noticed it took twice as long as before to start the bike. Before it would start right away but not now. I took bike out for about an hour through all the gears. Bike ran exactly the same as before. I could not feel any changes in the bike other than the hesitation starting. I have read how much of a difference it makes adding the BAK & Power Commander on many bikes but I cant feel any change at all. Is this normal? I guess I expected too much.
