S&S 98" Bolt-In Big Bore Kit

I had an experienced tech install it. As my '04 heritage is EFI I had an experienced local shop put an initial flash (rich mix) for the 500 mile breakin process. Changed the oil at 150 and at 600 miles then back to the shop for the dyno tune. The ride has V&H super shorts and a Ness stage 1 intake. End result: The bike charted at a max of 77hp at 4600rpm. Now you have to understand a few things: 1. The bike had a gear driven cam kit with S&S 510 gears that are great for torque 92t@ only 1800rpm all the way to 4000rpm. 2. You don't max your engine at 4600 rpm often if ever. The useable hp/rpm ranges are all greatly improved. Including 60rwhp at only 3500rpm. The bike will now comfortably do 60 in 4th gear and interstate speeds are achievable with out high rpm on the engine.

It's awesome.

You need a tuner with this conversion, thundermax it. 585ce cam is the ideal addition, with the TC3 plate and pump. Heads are a good idea...BUT...best route/value is the big kit and not the bits and pieces.

Absolutely freakin fabulous! Turned my old tired 2000 Dyna with stock TC88 into a monster. Also added S&S .585 cams and cam chest kit, and S&S super stock 89cc heads with a Mikuni HSR 42mm carb. Now this old Dyna's a revamped pure-t road burner.

Awesome. Great website, have not had any issues.
