Stealth HD Chop build
Not really sure where to put this - but as a few people asked for a build thread, here it is....
Basic idea is a pretty understated bike, mostly matt/satin black with the odd chrome highlight.
35 deg rake with 4" overs
DNA 41mm Wide glide, twin disc front end
240 rear, 130 front tyres on 18" rims
Solid mount softail frame
Ultima 6 speed LSD with 1.75" offset
Ultima 3.25" open primary
127ci Ultima black gem engine
Drag style bars
Combined pulley/brake on rear running 1 1/8" narrow belt
Going to be doing a lot of the fabrication and machining myself (as I have the facilities to do so), other than the frame which I will be leaving to
the experts. Went to see a couple of local frame builders last week and I think I have decided on who I am going to have make my frame.
This is a rough sketch of the overall look I am aiming at:
 
Desin rough
No doubt things will change and evolve as the project progresses.
Sourcing custom HD parts in the UK seems expensive but I have managed to pull together most of the major parts through US sources. Last major
component is wheels.
This is the engine:
140rwbhp and 145lbft torque
Most major parts are on order; engine, gearbox, primary, forks along with primary spacers. Frame will be ordered on Friday with a 6-8 week lead
time.
I havent decided on spoked or billet wheels yet - but that decision may be down to cost at the moment.

it'll look cool, spoked wheels would get my vote
I know of a good wheel builder if you supply the hubs. Which wheel option is the more expensive?

Awesome engine. I know it's not the done thing and I'm not really into choppers but have you considered having rear suspension, something
like Harley softail if you don't want it too conspicuous.

Good luck with it David - Id still like to have another go at a custom sometime.
I liked some of these designs when I was researching:

Excellent, good luck Monkey Man 
I considering a Bobber build when the 7 is eventually finished.
Keep us updated!

The frame is softail yes - hardtails are too skittish around the bends by all accounts. The hard tail look is cleaner - but I consider that to all be
part of the challenge!
Hardtail is perfectly legal.
mSVA is also a lot simpler than a full car SVA and is still SVA rather than IVA so costs around £110.
The Exile bikes are lovely and the bloke is a true nutter. I like the clean lines and I must say theres going to be a little inspiration drawn from
them.
With regards wheels, I am looking at billet hubs coming in at around $750 each plus shipping, VAT etc. Or spoked coming in at around $550 each + VAT
etc
Nothing is cheap when it comes to bikes. I also want to keep everything new where I can as I want a new reg # at the end of the build

I think thats what finished my custom off in the end - there seems to be a huge price difference between getting a chop to work and look
"ok" and getting the really clean look that the exile bikes have (and i really like).
My fabrication skills arent good enough and I couldnt afford all the billet (mostly)US of A custom stuff - hidden controls etc which make a huge
difference to the look of a chop - and lets be honest - its all about the look.
You're gonna have to spend some money David!
Keep us posted....

I'm interested to see how this works out I used to be a biker in the late 80's/early 90's, went to the Bulldog Bash and all the
other rallys every year, was in a club etc etc BUT although I loved the look of some custom bikes (especially the more radical minimalist ones) but I
always used to ride the sports bikes of the day because ALL the custom bikes I tried were absolute pigs to ride!!! I know you're one of the
people on here who knows what they're talking about so I'm interested to see how you take the move from function over form (7's
aren't pretty lets face it!) to form over function  Hardtails are NO fun from my experience but you'll get no style points for a
softail!!

With power figures like that, why has nobody built a Harley powered BEC?
The sound would be epic and REALLY confuse people!!!

Thanks for the encouragement chaps. Will keep you posted on progress over the coming months.
I expect its going to take around 12-18 months to finish the bike.

Probably because one of those engines will set you back around £4k.....

I don't think the £4k is the main issue as it's not that much up on a late 'busa etc.
I think the answer lies HERE
Think you may need a periscope!

nice parts list, a hard tail is absoulutely fine, to be honest I would have to say that a well built hardtail will ride as well as, if not better then
a bad or average setup softail
just make sure whoever does the frame is reliable and reputable
if you need the MSVA manual then its now totally free download online from VOSA
was updated last month so get the latest version for free, seems like a bargain to me
heavy is good, heavy is reliable, and if it breaks, hit them with it

Surely you would be better slipping that engine into your Car!
but, like others, i look forward to the build pics... I've watched American Chopper enough times to think 'I could do that'

Because Harleys are truly agricultural in comparison to modern superbike engines, which use 21st Century technology and actually have the gearbox
built into the engine.......

The TC harley engine does have the box built into the engine - but they are a pain for a custom bike builder as virtually no after market parts are
available yet.
Agricultural? No, not really. They are very simple engines though with a very well proven design

Sorry, Agricultural was perhaps the wrong word to use. 'Tractor like' would probably have been more apt.......

^^^^ doesn't matter if the engine is using dated technolgoy since chops are for show and not go.
good luck with the porject - I looked into building one but got put off by the cost - you are gonnna need deep pockets ... will make the GTS you sold
look cheap .... and unlikely to recoup the money but then money is not the point.

Well the engine, primary, frame, gearbox and a few odds has totted up to around £6.5k already.
The last really expensive bits are wheels and tyres at around £1500 for a set and a set of forks which are £600 with yokes.
After that I can make or modify most parts myself - or at least thats the plan!

There is nothing 21st century about a gearbox built into the engine the mini had them in 1959
