Does anyone know if the SE 50mm Throttle body will work on my '05 Ultra Classic?

Will it work with the cruise control?

I'm debating trying one out, and I wanted to ask here first. I'm also going to talk to Dr Dyno about it tomorrow when I see him, see if he thinks it will do any good or bad for me.

I'm not sure of the stock throttle body sizefor your bike. But, bevery leary on increasing it 50mm on a stock engine unless you have proven dyno results for your application. Problems arise with intake velocity as you increase the size of the throttle body with larger = less velocity. On a stock motor you will loose torque at lower throttle settings. Good luck !

Man a 50mm I have a 38mm on my 99 M&M FI setup. [:'(]Anywho I can't think or know of any reason/reasons why it would not work with your cruise. 98" build not really sure you need it or it would really help that much verses the cost toHP ratio would be low in my book or high whichever way you'd like to look at it. I mean really what do they cost? $300.00 - $500.00 for what 3-5 HP not realistic for me. Now if you had a 124" monster in there then HE!! ya go for it................... I could go on and on, somewhere you got to say/draw the line, enough is enough. Have a great day.

 

I think Doug at HQ would tell you to forget about it!!!!!

 

What Buttman said. My friend, pirateye on this forum, Kevin on the HQ Techline, did his 95" HQ build with Doug's specific recommendation to use the stock throttle body.

Unless you are going really big on the engine and will run it at high rpms, the only thing the 50mm SE Throttle body will do for you is give you another line item for your forum sig, IMHO.

 

I think the S/E 50mmis a twin port/two runner intake setup...[sm=smiley2.gif]

 

Is the 50mm throttle bodywhat is on the V-Rod? A guy I talked to today about my build I'm doing soon said that the V-Rod throttle bodywould be perfect for my app. I nodded and said ok, I'll look into it. I havent heard anyone doing that modyet.

 

The V-Rod intake will not fit the 45/V-Twin...But it might fit a Boxter....

 

I pretty much have known the same thing, but I figured if I could get this thing at a great deal that I might try it out.

I think a 48mm would probably be a better fit, but this one is a 50mm.

Most likely I'll stick with my stock throttle body, it's working fine for me as is...............I should just leave it alone

That's a great idea Steve!

Velocity was mentioned above and that was spot-on. All a it "might" do would be increase the top-end HP (at or above 6k RPM - BFD) and reduce torque down low.

Carl was right, though.... It would be another sig file line item.

The S/E does support cruise control. It is a 50mm siamese runner (single) TB. For a larger (maybe 107+) motor that is fairly aggressively built, it;s a great value ~ pricewise. It is also designed for 06 & later bikes. THe sensors have slightly different connetors than the pre-06 bikes. This means more work changing connectors.

Forget it!

Wait! I may know where you can but a Geralomy Dual Independent Runner (50mm x2) TB.... and all the fittings are already correct!
