Does anyone have dyno results for twin cooled motors with stage one mods done? My bike with the SE air filter, a 2:1 exhaust and tuner feels to fall on its face at about 4,200 rpm. It doesn't feel like its worth reving any higher.

 

Fuel Moto can help you out...give them a call and/or check out their website...

 

what kind of a tuner, who tuned it?

 

Fp3. Pulls real good till the higher rpm's. Rides really good but falls on it face when winding the gears out.

 

It looks as though the motor drops the horsepower at about 4,000 rpm. This is probably what I'm feeling.

 

Mine seems to do the same it falls flat about 4200-4500rpm and I have stage1 as well, twist the throttle at 4000 not much happens. I just sent a map to Jamie and he sent me a revised one back so ill try this one.

 

You will find dyno charts from Fuel Moto on a stock 14 Limited and many on the same bike with different mods on this thread. https://www.hdforums.com/forum/touri...l-moto-15.html You will find the Dyno charts starting on page 15. On the completely stock 14 Limited the torque peaked at 90.2 at about 4K rpm's then started dropping.

I have a 14 Limited with a Fuel Moto Pro Billet air cleaner, CVO mufflers off a 13 CVO Ultra Classic with 1.75" Fullsac CVO Power Cores, and an FP3 tuner. Since adding the stage 1 mods I just listed it pulls hard all the way to the rev limiter. I'm using the FP3 map for the V&H Twin Slash rounds with standard baffle that I have auto tuned and applied 4 times then finalized. Mine did seem to loose acceleration around 4K when stock but doesn't since the stage 1.

 

I auto tuned twice and finished. The thing is that I don't wind through the gears too often, legal reasons, to help the tune in higher rpm's.

 

I auto tuned twice and finished. The thing is that I don't wind through the gears too often, legal reasons, to help the tune in higher rpm's. I'm using the pro pipe, standard baffle, and SE stage one air filter. I can't really tell any difference over stock other than sound. I have a very fast softail and a slower shovelhead so getting accurate seat of the pants results is kind of hard.
