06 Big Dog K9, 117 CUI, but only 70 hp?

[Big Dog Tommy]

Hallo Zusammen,
Mein Name ist Thomas aus Deutschland.
Gestern habe ich einen großen Hund K9 von 2006 gekauft.
Heute habe ich in die Fahrzeugpapiere geschaut und da steht geschrieben:
117 CUI S&S, und 52 KW, das sind 70 PS. Hat dieser Motor nicht 120 PS?
Es gibt auch einen Forcewinder-Spyke im Inneren.
Was könnte es sein?

Welcome from NJ,
I can't read what I think is German but 70 HP is not correct. Have it put on a Dyno if you want to know for sure what the engine is putting out. My opinion is if it runs strong who cares what the HP is?

I agree, on occasion I will open throttle and there is so much torque I can hear my brain telling my hands to hold on tight and squeeze the handlebars and don't let go.

Hello everyone, My name is Thomas from Germany. Yesterday I bought a big dog K9 from 2006. Today I looked at the vehicle papers and it says: 117 CUI S&S, and 52 KW, that's 70 hp. Doesn't this engine have 120 hp? There's also a Forcewinder Spyke inside. What could it be?

All 2005 big dogs came with the E carburetor and restrictor plates between the manifold and heads. Some very early 2006 models came with this setup too. Off the showroom floor with the stock exhaust, these bikes would only dyno at about 70 hp. Now, they still made a good bit of low and mid range torque, so they felt very powerful for a 70 hp engine. Check the left side of the carburetor. It will be stamped either E or G. If you have the E carburetor, you will see a nice gain by upgrading to a G carb and manifold. If you have the G, then that 70 hp is just plain wrong. Even with the stock exhaust, which you probably have to pass noise regulations, it should still be above 90 hp.

As for the air cleaner, I'm not aware that forcewinder made an actual spike. The forcewinder has an elbow and a K&N filter out front. A few pictures of the exhaust and air cleaner would help us know what you are running.

Per Captain Amerika, For Big Dog's there isn't a "Normal". On the 117 ci Some have E's and some have G's. If you are running the Super E from the factory you are running smaller valves. The motors with the Larger valves are running the Super G carbs. If your running a Super E and want more Horsepower get a set of heads with 2 inch valves and a Super G carb and let that motor breathe and make more horsepower.

Ök, vielen Dank für diese Informationen.
Morgen schaue ich und mache Fotos.
Ich frage nur, weil in den Verkaufsdaten 117 ci mit 120 PS stand. Deshalb möchte ich wissen, ob die Verkaufsdetails nicht korrekt sind
or the written thinks in the bike-paper. That someone make a mistake by copie the details from us papers in german papers.

According to Power Sports Guide the S & S 117 cu in engine provides approximately 115 - 120 horsepower and 128 ft. lbs. of torque.

I was also under the impression that the E carb bikes had smaller valves. According to John Sachs, he has never seen anything other than 1.94" valves in the bdm 117 heads, and he has done a ton of them. The 2" valves came in the non-epa 117 crate engines directly from S&S. These engines were a completely different animal from the 117's in our big dogs. Bdm 117's have 9.6:1 compression, epa cam, and 1.94" valves. A real S&S 117 has 10.2:1 compression, 2" valves and a 600 cam.

That's probably where he is getting the 120 hp rating, but that's for the S&S crate motor. A Bdm 117 isn't going to be close to that. A stock 117 with a good set of pipes is going to be in the range of 95-105 hp.

I have a G carb and it would be fun to know my horsepower but for now I know My Dog has bigger Balls than I do.

My 2006 Pitbull has a G and I'm totally satisfied with the performance. Thirty 35 years ago I went to the extreme and things tend to give under extreme stress. I'm basically a cautious defensive driver now. The head doesn't turn so good with arthritus setting in.

It could be for the EU specs to be met, someone has changed it to 70hp? Not actually changed the motor but the paperwork?

Hi
Here is Thomas,
now I make a few of pictures. It look like, there is the bigger "super G" on board. But also writes "shorty"
so is it the big one or the shorty one?
And i also make a picture from the Forcewinder-Spyke .
On the motor i can read "super stock".
And the paper writes 70 hp??????

And i have a second question.
From my harley i know the "cold start line". So I can play with the cold start, if I make the line in or step by step out.
On my Big dog, there is no cold start line, there is a plug and i only can take it high and when i drill the plug go completly down,
and sometimes the motor go out. Is it correct, that i can only choose with 100 % cold start or 0 %, nothing between?

Thomas, now a little bit confuse.

Yep, you have the G carburetor. That means no restrictor plates. The "Shorty" is just the style of carburetor. The E and the G are both shorty style carburetors. You should easily be making at least 90 hp, depending on the exhaust. The EU requires a fairly restrictive exhaust to comply with noise regulations, so they may be hurting maximum hp a bit. That 70 hp on the paper might have been changed for regulations or insurance purposes, as Hman said. I wouldn't worry so much about hp numbers. It should have plenty of muscle. Have fun with it!

I don't think the air cleaner is a real forcewinder. I've never seen one like that anyway. It looks like a generic aftermarket spike air cleaner.

As for the "cold start line", are you talking about the enrichner device? You should be able to open it partially to help the motor idle during the warm-up period. It sounds like there is some kind of "all or nothing" system installed, if I understand the translation correctly.

 

[HMAN]

Thomas, try giving the throttle a twist or two and press the Run switch, and then start. Most dont use the enrichener/choke. If the bike wont idle, use the S&S method of reseting your carb to factory settings. That process is on their website.

And Matt is correct. You have what appears to be a D&M twisted spike air cleaner. I have the same one on my Pitbull.
I think someone has made a change in paperwork so it will pass all tests in EU? It has more than 70hp.
