I just got my 08 Fatboy (17k miles) back from the dealer. I already had a 96" stage 1 and then had the SE 103" Big Bore kit installed w/255 cams along with a Power Commander V (replacing my V&H Fuel Pak). I was just looking for a little more kick and the money wasn't too bad. I had my first ride yesterday and it was a lot of fun. The engine ran very strong and really jumped when I twisted the throttle. I took it easy though. The dealer recommended putting 500 miles on it before they tune it on the dyno and they installed a canned map for now. I got exactly what I wanted out of it and I can't wait to see how it performs after the dyno. I'm thinking I should have had the manual pressure release valves installed. It seems a little harder to start than it was. Is there a market for stock 96" cylinders, pistons, and cams? The Fuel Pak is going on ebay.

 

I did the same build on my 10 deluxe. I really like it. It suits my riding style. I also have different heads with no compression releases. My bike starts fine every time. You will be happy when you can really twist that throttle.

 

also have them check the mapping on your PCv. when i put mine on it had a little harder time starting so i had to do throttle settings then it was all good

 

I agree, the 255's have a lot of static Comp. which can cause pinging... and is hard on starters.

Its a good cam for heavy touring bikes that's ridden mostly 2 up and the bags and boxes filled that want good performance between 2K-4K rpms.....

For a lighter bike ( IE-- softails) that's ridden solo, there are several other cams in the SE line and Many-Many-- Aftermarket cams that will do/work better and will be a lot easier on the engine..
