Title: Interesting Hot Rod Heads on eBay
Post by: JW113 on February 18, 2018, 03:39:17 PM
Was surfing ebay for cheap entertainment, ran across this:

https://www.ebay.com/itm/Harley-Davidson-Ironhead-Sportster-900-S-S-Dragbike-Ness-Digger-Chopper-Heads/142691652957?hash=item213915d55d:g:GUYAAOSwEW9ahia5&vxp=mtr (https://www.ebay.com/itm/Harley-Davidson-Ironhead-Sportster-900-S-S-Dragbike-Ness-Digger-Chopper-Heads/142691652957?hash=item213915d55d:g:GUYAAOSwEW9ahia5&vxp=mtr)

What the hell? Ever seen/heard of heads like this before? Maybe set up for a twin throat Weber?

They look really cool, be just neat as conversation pieces. Probably dual carbs I would suspect.

Thanks Gary!

One thing that got my attention is those heads are described as "chrome plated", which can be seen on the edges of the fins. The thermal emissivity of chrome is horrible. And on an iron head, which holds heat much more than aluminum, seems like a recipe for serious detonation. Maybe a fast blast down the 1/4 mile is what they were made for?

As long as those heads have been around, hard telling how many bikes they've been on. Along the path they could have been on a show chopper of some type, maybe a completely chromed motor.

Completely chromed motor, yeah I've seen a few of those over the years. There's some serious form over function for ya!

Show bike stuff, and an A for the effort.
An Iron XL head, even with porting/brazing, does not warrant the need for 2 carbs.....lol.

Over carburetion is a long standing tradition, couple that with some flatulent drag pipes, a kick starter, magneto, hand shifter, suicide clutch, and no front brake, you have the perfect recipe for a wet dream.

Speaking of wall art...

It's spring cleaning time. Found this at a MMA swap meet years ago. Why I bought it, I have no idea. Oh wait, now I remember. It was CHEAP.

[attach=0]

This is a gen-u-wine Solex (Weber knock off) side draft twin throat carb, mounted on a Shovelhead/Ironhead style manifold.

[attach=1]

Interesting, it merges two carb carb tubes in to one, then back into two. Like an "X-Pipe" only on the intake side. Hey!

It came with a "spare" Solex carb. My guess they came off some 60's Mercedes or something. So what to do? Toss it, keep it, sell it.... decisions, decisions....

I'd clean that up and make some type of man cave display. That's pretty neat.

Yeah I was thinking about doing that, clean it up real nice, mount in on my Ironhead with a couple velocity stacks, take a bunch of pics. Then pull it and hang it on the wall with the pics and a homemade fake plaque of 1st place at Fremont Raceway from "back in the day". Oh the wicked lies I could tell...

My dad's got one of those Dellorto 40mm dual throat carbs, that's been in a box in his garage for goin' on 40 years. No idea which model, but he said that for some reason it would've been a royal PITA to make it work on his 86" Shovelhead & went with dual 29mm Mikunis.
