Love this build. Hotrodding at it's finest!
Not sure why you need a fuelpump? To me it looks like an old Volvo SU? I used to have one of those on my shovel. No pump, no problem. If you're worried about running lean, an idea maybe would be to run 2 bowls. Added plumbing I know, but would look right at home with the racey look you're going for

It's not a cast piece, it's from an left over box at work.
The damn piece was eloxerad ( swedish word don't know the english word) Anyway. i finally pulled through but it was not pretty but no one should know unless i run them over, but then they will have bigger problems than an unpretty weld

I piled miles on it for 2years but since children arrived in my life its easier too sneak out at night to build bikes than to sneak out at daytime to ride bikes. now it's chopped anyway

I have the old Dollar sullivan papers for modifying volvo HIF6 SU's for use without fuelpump but it does not apply to my MG HS4 SU. It needs a pressure of approx 0.2bar to work properly.

Thanks for loving the build. Can't have enough of that

I'm having a hard time sticking with one part at the time.
There are alot of almost done parts in this projekt.
I'm influenced by dragracing and old aircrafts so i almost made this:Attachment 83689
It's a safety device in case of backfire. But im not completely satisfied with it. screws are to many and to small.
So a new one is in the making, and so it goes on..

A burst panel?

All the ones Ive encountered have springs forcing the plate closed against the block. They are rated at way more pressure than the blower makes, but less than it takes to blow the heads off.

Had to google that.
Yes it's a burst panel. Designed to burst at an explosion but foremost to look cool on my manifold.
I will have an springloaded pop off valve to handle small backfires and such. But i haven't found any designs that i like yet.

You could make one that was a cone shaped plug. Have it on a tri-pod bracket, with a stud mounted on the backside. The spring would force it closed by being under the tri-pod bracket with the stud allowing it to be forced open but stay straight and the shut by the return spring.

Think valve in port with a valve spring but the valve face would be facing backwards and the valve would be outside the chamber being pushed away.

I've been thinking about this. your idea ain't bad.(read good)
My latest ideas are leaning towards some sort of rocker like in a valvetrain. Function is easy. function and looks is difficult. Soo i will change my mind again and again....

during all this mindchanging i keep fiddeling on my pressure pipe and bloweroutlet. There are a lot of welds on that thing but i will grind most of them down and sandblast it for a more cast look.
I throw in an mock up pic to give an idea of final look but im not pleased with it so i keep change my mind again.............

I think this build needs a speedmaster tire and a new handlebar.
21" rim and spookes showed up today and a set of pipes with internal throttle and ignition showed also. The style of bar in mind belongs to one of the most worn out styles around here.
the boardtrack.
Just writing the word makes me sick.
But since most people is soo far off the mark by, doing it half ass on a japanese 80-ish midsize what ever, it still feels fresh to me.
If i nail it i will post it.

Haven't got around to that yet. damn i'm slow
To make myself look better i blame my workbuddy's severly overcrowded garage. Since he has an pipebender but has been unable to dig the bender out. But this weekend he has to dig it out to bend some for our workplace. So that excuse won't work no more..

I laced up an 21"rim and mounted an avon tire. Soon all the bobber attributes will be gone.
Left is just the world's slowest badass flathead dragbike

Sometimes it feels like this thread is from me to you. But it's ok. i kinda like it.
If i was washed up on the shore of maui, all i needed to do was find an computer and post an pm, and i would have at least have an couch to crash on.

Default !

Finally the plumbing fits!


That thing under the charger was a plain bent pipe in the beginning. After being cut up 7times and welded back together it took some serious work to smooth it out again. Tada! now it's a plain bent pipe again
But with a tighter radius...

And i will have to make my self a third burst panel and pop of valve. to make the plumbing complete

But i have all i need for the new handelbar. That feels like it's way more fun so that have priority.

Inspired by at not too unfamiliar pic...



I also ordered some meathookgrips but i don't know if im gonna use them. They where so cheap i couldn't resist.

Ahh..! good to know. If this very unlikely chain of events took place i would know that it would all work out in the end.
