Re: Anyone else?
Now that is the big unknown.
Nowhere I can find is an actual spring rate listed for the harley shocks.
So i have no firm calculations.
What I have done is take the weight of the rear of the donating motorcycle and backwards calculate it through the mechanical ratio. Then apply it to my weight and ratio. By this it is still way too much spring.
Now that this much is together I can set the axle down on a block then put my body weight on it and make it move about a quarter inch.
So far it looks promising.
But if not I will do something else.
Do really wish I had more real spring data about the shock.
It may very well support the weight but be terribly soft with no per inch data available.

Re: Anyone else?
Sounds as though it has the same downward movement as a my springer , I was actually thinking it may be to soft for the weight . If that's all you can get the spring to collapse it should be fine , curious to find out how it works . Like I said earlier that's a fine job , I'd run one on my scooter ThumbUpThumbUpThumbUp

Re: Anyone else?
So the 2387cc stroker motor is coming along. Had to do a lot of milling and grinding to make room to swing the big crank. Cut the case for a lip seal on the pulley. Made a two piece bolt in windage tray. Stated on a plug to block off the dizzy hole.
Even had to cut notches in the cam to clear the stroke.

This is an amazing build man!!!
Any new updates since Feb?
I also sent ya a PM regarding some parts.
-
Yes there are some updates.*
Still not together though.
Things got real slow here and I quit keeping the thread up to date.
I will get back on it shortly.

I made a little baffle plate to cover the distributor drive area. My pressure bypass is in the gear cavity area instead of right at the push rod tubes.
Hoping the baffle will keep the oil from flinging out the fuel pump and distributer holes.

Moved the oil Porting around in the case.

Then started whittling on a coil mount for a Ford coil.

Most people just rebuild ... seems you're redesigning :D

So now the distributor hole is the oil filler.
The fuel pump hole is the crankcase vent and the oil cooler mount is now the coil mount.

Checking the shifter clearance.
[ATTACH=CONFIG]47753[/ATTACH]
Looks like it will clear the coil.
The 4 in a row throttle bodies I cut into pairs are all the same casting. Just machined or not in all the places. So all I had to do was machine in the bosses for a place to put some throttle linkage.
[ATTACH=CONFIG]47754[/ATTACH]
Then machined the motorcycle throttle bodies to fit automotive injectors.
[ATTACH=CONFIG]47755[/ATTACH]
Then went to machine the fuel rail, but decided I did not like the way they turned out.
[ATTACH=CONFIG]47756[/ATTACH]
So i started over from scratch on fuel rails.
Took the box of electronic goodies.
Soldered up the board.
[ATTACH=CONFIG]47750[/ATTACH]
Powered it up and loaded some code.
Had to do some troubleshooting. I had a transistor soldered in backwards.
Got it sorted and started writing map tables.
[ATTACH=CONFIG]47749[/ATTACH]
All the inputs and outputs work now.
[ATTACH=CONFIG]47748[/ATTACH]
Soldering some cables.

Holy Moly man!!! You are doing some real serious designing and mods to this puppy.
Wow, I am very excited and interested in seeing how the electronic fuel injection works on this.
What compression ratio are you figuring on running? Stock or are you going to have to lower the compression?

Whittled out a set of fuel rails.

Started on some linkage. Going to use cables this time instead of levers.
[ATTACH=CONFIG]47758[/ATTACH]
Made up some air filters.

A buuuuuunch of cam.
Dynamic cr will be pretty low under 3k rpm.
Static calculated target is 9.5 to 9.8
Dynamic under 3k around 7
Once the cam comes in the dynamic will come on up.

Starting on the pulley hub to adapt a Ford crank trigger to to it.
