Don't seem too bad. I think the 1130's normally get around 100 hp without any real work to them

That sounds pretty weak to me. When I had my black widow slip ons and a generic map in my Powercommander 3 that wasn't custom I pulled 110hp. With a proper tune I was expecting to get around 113 or so.
97 sounds very low to me.

Was that a 1250 or an 1130? Cause that sounds about right to me for the 1130

Ride it. If you like it buy it.

These numbers are all over the place. Different days, different weather, different dyno, different gas..................they should only be used from a base line run.

Though I do agree those number sound a bit low. I have an 06' D 1130cc with the Vance and Hines Comp 2-1 exhaust and increased from 104hp to 112hp at the rear wheel with a proper tune. It depends on several factors really. Vambo is correct in that temps, humidity, gas all play a certain role in the deciding factor. More than likely you just got on a dyno that has low readings. Most people just use the dyno for an increase reading. Take a base hp reading, do your mods and tune and then compare your increased HP to your old to see how much the mods/tune helped. If you're really concerned about the readings being low try a different dyno or different tune. Or get someone else with the same engine to do a pull on the dyno and see how far off your numbers are. Now remember there is variation between all bikes by a few HP. But if there is a 10hp difference I'd say there could possibly be an issue.

Also would depend on what exhaust is on it, you just mention it's got a aftermarket. If it's something like the toxic exhaust that could explain the drop in HP.


EDIT:
Alright so I just found the bike on Ebay and it's running Rinehart 2-2 Staggered so that would explain the numbers now. If you check out this thread you can see that with Vambo's point and that exhaust it's probably about spot on.

yeah I often forget people actually put 2 into 2 exhausts on these bikes even when we all know it kills power rather than make more lol.

Mine is an 1130. Normally I'd say just ride it and if it feels like its got good power, roll with it. Dyno numbers are usually relative to that dyno and the variables in that area.
But I'd expect no less than about 110 out of a stock motor no matter where you're located unless its got the exhaust done which may drop it some. You've gotta consider that it pulls what, 120-125 at the crank? So 110 sounds like a reasonable number at the wheel. 97 seems like a big leap from where it should be.

Personally, I'm not a numbers guy as long as it feels like its got the pull where it needs it UNLESS those numbers are significantly lower than the norm that I read online.

The 120-125 number is for the 1250's too. Not the 1130, typically they say it's 115 for the 1130 at the crank.

that depends on the model. While the 04' he's talking about yes it's 115 at the crank. The VRSCRs and VRSCDs all came with 120 at the crank. It's why the VRSCD's are so desirable. You have basically the same power on a lighter bike with Mid controls and highway pegs and it can lean little bit further due to it being an inch taller or so. So you have the best of both worlds.

I ride with a guy with an 08DX and an 2010' F and I can steadily pull away from both of them. They have the bigger engine but after changing my wheels and shedding about 50lbs in weight "exhaust, rear pegs, etc". I've got almost 100lbs on them.
