Looking really nice Kevin!  Damn weather isn't cooperating here either.  It's been raining for 3 weeks straight and yesterday we got hammered with hail again.

Kevin, I'm curious as to what type of fuel do you plan on running in this motor?

At the moment normal unleaded not sure of the rating, but if it nocks I will use an octane booster. I think I am slightly advanced on the timing, as it spits back when cold, but will keep it where it is until I have the carb correct. I may switch to a concentric for development as I grew up with this carb and it may save me some time. I can't use it on the road to test it properly yet, I did have a very quick potter up the road, and took it upto 50 ish and it was very smooth and comfortable, too short a ride to get a proper feel though.
I have decided I don't like the sound from the 2 into 1, so have just hit Hitchcocks to go the separate pipe route, I had to order a couple of gaskets and you know what its like, you get carried away. :-)

I was actually going to ask about the exhaust.  Is that a factory Connie exhaust?  If so, I have heard that they are less than ideal and a lot of guys go with dual exhaust.  That was one of the reasons that prompted me to build my own exhaust.  What did you not like about it?

It sounds like a cross between an early 2 stroke and an old super dream, and also it is too efficient I can here too much mechanical noise (there is no baffle to remove), I prefer a bit more bark.

Looking at the old brochure picture for the '56 Trail Blazer on the Hitchcock's gallery, I see it would have had twin pipes and what looks like Burgess type silencers. A couple of Indian shorties for a 350 would look pretty close and probably give you a bit more blat (depending on the manufacturer), unless you had something else planned?

Hi
Yes Adrian, I thought as the engine is basically a Connie that the siamesed pipe would be the one to use, but as you say originally it had separate pipes. I have ordered the pipes from Hitchcocks, and the silencers from the parts book, they do look like the Indian shorties. I will leave this pipe on for the MOT, then fit them after.
Here is a short youtube video from earlier today :

Ironing out a few issues while rebuilding the top end with more clearance on the pushrods. The alternator and stator had made contact, and there was a crankcase venting issue. I have fitted an Electrex ignition and stator kit, (timing driven from the crankshaft, and a 70w alternator in one), and added a crank vent along with earlier breather to help reduce crankcase pressure. Here are a couple of pictures:

I have the single-cylinder version of the Electrex waiting to go on something, though the alternator side of it only chucks out 50W - LEDs all round when I fit it to a bike, methinks!

Let us know how well it fares on ease of starting and how well it copes with the lights. Basically it's a more up to date version of the CDI type alternator that RE India fitted to the K/S 350 Machismo and AVL Thunderbird models:

Fitting twin carbs, I found that Concentrics will fit and let me keep the airbox.

Keeping the airbox is important for preserving a certain look, though it does not seem to allow for any kind of bellmouth on the carbs, let alone any filter, though salt spray rather than road dust might be the problem in your part of the world.

You could consider using the Fury-style battery mounting which was also used on some of the Indian badged twins. It still looks cool/vintage and would give you some room to tidy those threaded carb ends up:



The picture was supplied by a gentleman who had previously restored this one and sent me same details explaining how the battery was mounted.

Hey Kevin.  Did you ever get this build finished?  I'm getting ready to tear down my old Trailblazer and got to thinking about this project.  Would love to hear an update on your build.
