Some more springer detail:

The solid steel pivot for the springer. This springer is really beefy compared to the reproduction springers out there.

Here are the newly fabricated manifold parts:

This flange was fabricated out of a chunk of 3/8" steel plate. Turned out pretty nice I think. The intake diameter is 1"!

we can do it. you need to get a brother married every month or 2. glad you got more done here as the other projects threatened this one. bring that intake over and it will get brazed up asap. call again.

Ya Datz, The Springer On My Stretch Is Scary Floppy. They Just Drill A Hole Thru The Fork Tube And Run A Bolt Thru. It Gets Compressed. I Hope To Get Some Stainless Sleeves And Drill Large Hole And Weld Them In. Yellow Is Beautifull. My Tree Trks Are A Darker Yellow. Its A Good Safety Color Also. Ron

Tonight I scored a heavy duty spring made for the weight of the whizzer. Should stiffen the spring rate up quite a bit. Still looking for a front fender that I like.

Hi Guys,

There is a lot of difference between the "vintage" springer and the repo. The vintage has a solid area in the forks to support the bolt as opposed to a simple hole in the repo version. Good move on using the heavy spring it will help.

I am using the same vintage Schwinn front end and it works great!

Have fun,

A few new pics.. Got the new carb installed. I taper reamed the aluminum carb spacer which portmatched the 1" intake to the head pretty closely. I figure this will work OK until I can pull the cylinder to portmatch it to my intake manifold.

I set up the manifold so it can be used either with or without the spacer. without the spacer, it'll tuck the carb in a lot better, but its OK for now.

I was able to get the engine to fire yesterday on the new carb. Its running extremely rich, so it just barely runs with throttle halfway open until it peters out and dies. So, now I have to wait until I get the jet set from Dellorto. I got a call from Dellorto this morning saying the order I put in was delayed due to a problem with their order software, so they are shipping it out to me via 3 day delivery for free.

I wont be able to run the bike until I get the jets to get the carb dialed in, so I'm going to concentrate on cleaning up the wiring, fitting the headlight, and mabye working on the other project bikes in the meantime. I have a 3 day weekend with nothing planned, so this is going to be great!

Did you mount a headlight on your springer yet? I have a springer on 2 of my bikes & am trying to find the best mount for the light. Here's one I'm using right now. It's a 3/4 inch conduit clamp.

"I set up the manifold so it can be used either with or without the spacer. without the spacer, it'll tuck the carb in a lot better, but its OK for now."

Datz: Congrats for the job; it´s a nice set up.

If you use the spacer in the carb, the engine will have more torque and less RPM; If you do not use the spacer the engine will increase RPM and lower torque. (Not more than 3 - 5 %)

Good luck and best regards.

See you in the Road !!!
