'97 Heritage lacking power

Thanks to everyones input,I now have a lot of good things to try!
Hi all, Emma my '98 flstc was suffering power loss and heavy on fuel, a client recomended a Dyno, this was done Dec 09, turns out the HD techs opened the main jet to suit a 120c instead of my 80c, also here in Oz Fuel has changed ie no lead, and about 5 years ago they changed formulars again, Brian @ Bigtwin, advised using Mobil, Caltex '98, but not Shell, guess which one I'ved stopped using, since tuning Emma is BACK, hope this is helpful
 
I'd say time to do a topend, and while you're at it put in a bolt-in cam and some new higher compression pistons, lifters, cam bearing, you won't regret it. With a bolt-in cam and doing a topend you can either use the stock pushrods or change to adjustable. I just did my 93 fatboy this winter and used the stock pushrods.
