Bonneville America Forums Forums Technical Forums Performance Mods NH DYNOS (finally)

Just to let you know that I put the freak on and subsequently changed the jetting as I said I would ie 150 main jets.

I kept my pilots as stock cos I'm not turning out more than 3 turns. I also swapped the tbs back to stock and have one shim. So far she runs very nice.

I'm not sure yet if these are the best settings yet but I don't have any popping on deceleration and she runs strong throughout the entire rev range.

So my next step is just to keep an eye on the plugs but I would be surprised if I was anything other than rich, which can be sorted as the need arises.

BTW, I didn't end up taking out a baffle from my tors cos it just looked a bit too hard. Mind you, I was able to poke a stick up the spout so to speak and it virtually goes to the end of my pipes meaning, I have less restriction than some of the earlier tors.

All in all she's running probably smoother than any time I can remember which makes me think I might just be on track

Good on ya, John. Did you get a big improvement in torque?

Interesting. I have the same setup (pipes/filter) as you but am running 132.5 mains. Guess I'm pretty much on the money (bike runs very well).

I was told that my pilot circuit and my needles were fine but the my main was WAY to rich (perhaps as much as 2 sizes) BUT as I intend to drill out the airbox I knew I would be rich...so I may only need drill and drop 1 size (to a 132.5 instead of 130'S)

OK... The final setup is in my signature... Got 10 more horses out of it. 63.3 and the torque stayed the same @ 47.6
Carbs were out of balance and needed to put the 45 pilots in with a shim on the TBS. Bike was very hesitant prior to this tune. No fun to ride at all. Looking forward to next session. Aint touching a thing

Staffo... If you are running the freak/tors/150 then you are definately rich. I put bubs on with the same setup and that opened it up to a slightly lean condition. the 150 go well with the freak and bubs.

Yeah, you could be right Ralph. I'll have to see a bit down the track. Meanwhile the bike is running as good as ever with the current setup and until I can get a dyno to verify, I'll look at other clues to help me decide whether I go for lower sized jets or not. Thanks for the tip

Staffo... I would love to see the dyno chart when and if you run it with this setup. It would be nice to compare the two since they are so similar in setup. Just for the heck ofo

Yeah Ralph, I'm a big believer in sharing info with everyone. That way it helps others make informed decisions on how they might do their setup etc. I know I have been really appreciative of what others have told me so I like to return the favour whenever I can.

Now regarding my running rich. You reckoned I would be definitely running rich with my setup eh? Well just remember I am using stock needles with one shim and not TBS. With everything I've read and been told, using the stock needles does not allow as much fuel in our carbs between 1/4 to 3/4 (I think that's the range) throttle range.

Anyway, I've been too busy with stuff to have a good look at the plugs yet (it's not a priority) but one thing I can tell you is I'm getting approx' 5 mpg (UK gallonss) extra fuel economy than prior to installing the freak.Admitedly, I know I was definitely running rich with my other setup ie drilled box with uni blah blah balh, and I'm not saying I might not still be a tad rich either, but I just get the sneaking suspicion I'm close just cos of like I say, how well my bike is running.

BTW, like I said, I'm a firm believer in sharing info and will definitely show everyone my results when I do eventually get a dyno done. Just a shame though that we can't organise ourselves so that each dyno results that are proven with the scanned printout aren't being provided here for all to see. I thought at one stage we were going to do that and lots agreed it was a good idea, but it never really happened. It's just such a great idea to see dyno results just because it will help all those who have similar setups to mod their bike accordingly so that they should be pretty close to the money without having to actually dyno themselves. Also it's just really interesting stuff

Thought others might be interested. Here's the link to Pat's Dyno results

Ok I keep reading bout this freak,can someone tell me what the freak it is?

its an airbox removal kit, do a search tons of info on here about it

I've not had the chance to dyno my bike but I do see a few setups similar to what I run. I have SS shorts, open pod filters, 150/45, stock needles with no shims and about 2.5 turns out on the mix screws.

I've noticed that bikes with about the same arrangement (Staffo, Big Poppy) are charting lower HP/Torque numbers than just about everyone else, and in some cases very close to stock. Is this setup just lame or am I missing something here? BTW, my seat-of-the-pants dyno tells me that my bike is running stronger than ever.

This thread is great. I do intend to dyno my bike at some point so I have a baseline but it won't be anytime soon.

I do feel, however, that a vital piece of information is missing: how the bike was run/broken in. I imagine that a decent break-in can make a big difference in the numbers.

Just a thought.

In NH we put six bikes on the dyno, one after another.
This give a nice comparison of the different mods.
Comparing these results to any on another dyno rig is
apples to oranges. But it's still interesting.

Hey folks... It's been a while since I have posted here. Miss the place. I got a lot of good info from you guys. The sad truth is that my brother is currently enjoying my BA. The good news about that is I passed the info off to him and not now he is mockin around with my hard work
I am back to start asking questions about moding the new BA for performance. My buddy just purchased an 08 Speedie. I am giving him a set of my TOR pipes that have laying around. Will I need to mod the FI with these pipes? Do you need a device like a Power Commander to do mods on the new bikes? is the AI system required for proper function on the new bikes?

So many questions.

if I can upload these I would like to know what the experts think. its a 2006 TBA 790cc,at sea level, raask straight through drag pipes no other mods, 2nd run was after adding a cpl of washers to the needles.

Well, I'm by no means an expert, but looking at your a/f curve, it looks quite decent, maybe a (very) little lean in the midrange. When you say no other mods, does that mean you still have the snorkel in your air box, stock jetting and stock needle? 60 hp is actually a good number with your setup. Did you get a torque reading as well?

None???

Hey Pat, have you been smoken that green stuff again, or maybe I should cos call me stacka the wacka but I can't seem to find the tq numbers at

Am I going mad or just feeling dizzy from looking at the printout for too long.

Maybe I can't remember having a little smoke myself

have been told its poss to calculate the torque from the power somehow, anyone know how?
