I have a V&H V02 and it matches my HPI 55/58 just right. A smooth transition from TB to the velocity stack inside the breather.

I have the R&R Cycles on mine (HPI 55/58).I had read some good things about their backing plate.
After looking it over thatís what sold me.It also comes with external breather vents

I have the R&R as well. You just need to modify the brackets to insure you don't eat a fastener.

I bet Horse Power Inc has a high-flow air cleaner to fit their throttle body.

When I bought my 62 / 64 HPI it was one of the first 9 built.  Jimmy told me they used the 58 mm S&S stealth backing plate for testing so that's what I went with.  I believe their  bore size is the same as the 58 mm S&S.

Someone should really talk with the people at HPI before spewing more old or false information. Good grief.

I have a HPI 55 on my 09 SE FatBob
I used the SE Heavy Breather and did some very minor port matching
very good combo

I'm using the Screamin' Eagle Agitator on an HPI 58mm. I had it bored to fit as it was 50mm stock.

When I bought my TB they didn't have a 58 mm + size backing plate and had no immediate plan to make one. I would have liked to try their backing plate but you had to use what would fit.  I know you get that.  I bet you do or have done that lots.

When I called HPI and spoke with Jimmy that's exactly what I was told.   The bolt pattern and size matched the 58 mm  S&S.   I have 2 of them and they fit perfect without need to match the throat. .  One I am using and the other to modify later with a bellmouth stack.

Your right, the OP should first talk to HPI but that doesn't mean he can't look for options or the other members here shouldn't share their experiences with the HPI or their throttle bodies when the OP actually asks the question.  Maybe you didn't read the opening post.   :nix:

Yes,they most certainly do. I just personally chose a different direction after looking at what they had to offer.Absolutely nothing wrong with what they have available       Coff 06

So I have on the shelf an old Fuel Moto Ac/dc air cleaner from my 09 TBW FLHX. Fuel Moto sells one plate for stock tbw and one for stock cable operated. Is the only difference between these the size of the opening on the backing plate?  if so, this might fit with a little modification to port match?

I looked at hpi. Didnít know about r&r, Iíll look at those too.

Thanks for the info.

I recently installed a HPI 58mm T-B. My machinist that did the heads and cylinders bored out my Arleness Big Sucker back plate to match the T-B. It was a perfect match, I just had to get a new gasket which was bought at H-D.
