Thanks Dallara and DJ. It a relief to know the concept works, with the carbs and modified Dyna Ignition. With some help from Chris at SJBMW, I got the thing running. I have some fine tuning to do with the motor and the wiring to finish. With some luck, I can start on the paint for the the fenders and tank later this weekend. I am having my seat done by Johnny at Roberti Customs. Just got pics of the finished seat today. Check it out:

I just finished the crossover on the stainless steel pipes:

Now I have to have them ceramic coated. I can't make up my mind between silver or black. Here is the pipe with the natural silver finish:

Here is the same pipe coated black. Which do you think looks better?

Silver.

The eye almost follows the line of the intake stub, through the head and out the header. So for them to be the same colour appeals to my eye.

Your workmenship is unreal. Very cool.

I like the silver. I think the black looks cheap and boring, my $.02.

Nice, and another vote for the silver finish.

Silver...definitely. It's been a few months since I last checked on your progress. Very beautiful.

That is one Bad Ass soundin bike....I love it. The tone is so much better than an open pipe harley

Silver, for the same reason mdouglas said.

Bike sounds very good under acceleration, no so attractive at idle, IMHO.

Nice work so far. I'd go with the silver ceramic coating, I've done it on an RD400's DG chambers years ago, and it's a nice alternative to chrome. It has sort of a silver-light blue satin finish to it. Good luck with the project.

Today I installed the speedometer sensor in the rear ABS bracket. The sensor was made to pick-up with a Harley belt drive sprocket.

As you can see, the BMW ABS sensor ring replaces the belt drive sprocket successfully.

Randy -
Re coating the exhausts...
I'd recommend aluminum-ceramic coating the inside of the pipes and just polishing the outside.
I've done this and you get a slightly cooler running system (with a bit of power boost from better gas extraction), and...*nothing* looks a great as polished stainless when it slowly changes to a nice light straw color. The coating also sort of slows and "mellows" out this process and eliminates purple & splotchy "hot spots".
Here is my MZ Motard after I treated the headers this way...this was after about 1500 miles on the pipes. Now after 5500 miles they are a little darker but not much, and still "mellow"!
You can see it is a bit darker near the exhaust port and gradually fades to near clear "white" color at the end of the mid-pipe.
If you get a stain or spot on the pipe it's easy to rub out with Semi-Chrome or any metal polish.
Or you can machine-polish the yellowed surface bak to chrome-white anytime you like. After it has first been polished it is very easy to re-polish.
Whoever named stainless steel "stainless" steel must have been kidding!
But it is a beautiful metal and will polish "bumper chrome" bright and stay that way forever...unless it gets real hot!

Damn Dave...those pipes look great! Just what I needed...another choice

You know...out of all the choices, I'm leaning towards the black. The silver coated need polishing once in a while. The inside coating like Dave's need polishing once in a while. The natural stainless will turn brown quick. The black just needs to be ridden! I have been planning on coating the intake tubes and the center section of the carbs shiny black. I like what mdouglas said about the eye following the line from the intake thru the exhaust. I think with the added black items this will work.
hmmm...decisions....decisions
