106 build. Do we need SE injectors - update

[hotroadking]

07 Ultra. Getting s&S 106 with 585 cams beadwork by Kirby. Basic level one street cleanup same valves. Kurtakyn 57mM tb

Should we upgrade injectors and which SE part?

Also what are the SE plugs that help reduce ion sensor falsing

do you have 4.9 inj now?
if so, they should be enough, unless your having Kirby put the squeeze to the 106?
if you dont have 4.9 already,then buy some 5.3 from someone like HPI.
stock HD plugs should be fine on a mild 106. if you want to try some diff plugs? the v rod plugs and SE plugs play nice with the ION sensing most times. the only way to tell is try them.
if your a data collector run some data runs to see how they react.

It has whatever is stock in 07
haven't checked them out

No big squeeze but it's going to 10 to 1 per the kit

What's your estimated horsepower?

stock  will work . the duty cycle will reach peak at WOT . but for short WOT blasts they will work,
if your going to upgrade? just pass the 4.9 up and go 5.3. if your tuner dosent have any problems with tuning big injectors.

[HogBag]

Stock 07 injectors are 3.9

[Steve Cole]

The stock injectors are good for about 100 Hp, so if you plan making more than that they should be replaced. I would go with 5.3 if your look to make no more than 130 Hp and if your looking at more then go bigger. I just finished using the new 6.7 from HD and they worked out just fine but those should be more than your going to need for a 106 and 585's.

[hotroadking]

Well it should hit 100/100 as target. Short bursts to wot. It is a friends bike and doc did the current tune. I will have him ask doc.

You guys should get the 5.3's and expect more out of a 106.

[hotroadking]

I think he might want to consider moving them up to the 5.3 or get Mike R's Kuryakyn injectors,
there is not any reason to skimp on a few parts when you are doing the whole thing and then have to
do it over, including doing the tune, don't want to get on Doc's dyno and find we're pushing 100% on the
stockers and could have got more with the next size up. 

[hotroadking]

Thanks for the input found a set of 5.3 at Seminole HD nobody else in state had them
couple of the net sellers said they are on BO for several weeks.

He got 5.3 but they appear to have an -08 PN and looking at them the 07 connectors are not the same.

Presume there are 07 SE injectors?

Or could we change the connectors on the 07 to 08 and up EFI connectors on the harness.

thats why I said buy them from someone like HPI.
most 5.3's you see are for FBW T/B . not 06/07

[strokerjlk]

FWIW my 07 ultra when it was a 106 S&S @ 10.3 HQ 575 cams stock inj stock T/B beans heads .
went 100-105 hp 106- 118 tq. depending on the exhaust at the time

  The Kuryakyn throttle body uses the Weber injectors. The '08 Delphi injectors use a different electrical connector (mentioned) but they are also longer, so they won't physically fit the TB you have.
  I have seen the latest H-D red Weber injectors on a bike that I tuned, but didn't get them on the flow bench.

  The white (IWP162) and the brown (IWP043) Weber injectors (they are identical in performance) will be about 85% duty cycle at 115HP. That is safe enough.

  The IWP043 are 34 lb/hr, IWP069 (yellow) are 48 lb/hr, and the IWP189 (purple, Ducati 1098) are 54 lb/hr.
  Don't know where the H-D red IWPs are.

Will HD VRod Destroyer injectors IWP 190(6.37) work in an 07 cable controlled TB?

[Steve Cole]

Remember the Destroyer injector should not be used in a TC or any Vrod injector for that matter. The spray angles are all wrong and spray the fuel at the walls of the port rather than in the port. Hd has the proper injector for his bike but he just needs to order the right one as there are two different styles. The FBW bikes use one style and the Cable operated bikes use another.

Thanks Steve, In this case I am asking about my 07 with a 140hp 117

Dont do it Don.  they suck. Save the headache.

[hotroadking]

They had the correct 4.9 in stock so he got those, swapped the 5.3 out
never used we noticed the connectors right off out of the box.

so one night I'll get back over and get them installed...

Jim
In your experience what do you do for the cable controlled 06 up motors when you are working in the 140hp range for injectors?
Thanks

5.3 from HPI will do it.

you can have them modified to flow whatever you want. Dan (tx chop) just did that.
I heard Doug (Ugly Dougly) modifed them as well
Jay (jam 65) has some custom 7.2 we are going to try. forget where they came from . he has a thread somewhere

HD offers part # 27400002 that flow 6.2 gps that are for the cable throttle bodies
and part # 27400001 that flow 6.7 gps for DBW bikes

Both of these injector work well and will handle the HP your asking about. You just need to pick the one that fits your application.

[strokerjlk]

they offer a 6.2 but everytime i have tried to order them they are back orderd.
