Cone Engineering might be able to roll you some sections to build a set but, it would take a lot of fabrication work to weld them up, grind the welds back and polish the steel where it doesn't show up when chrome plated.  I would think it could be a difficult and very costly proposal.
Like you said,  fixing the pipes might just be chasing another area to break weakened by the welds.

Hello,

A quick update.  I am having a pair of replica silencers made in stainless steel by NRP Exhausts.  They have the originals as patterns so hopefully the fit will be good.  The headers are being re-chromed as well.  I'll post photos when it all arrives back.

Cheers  Geoff

Happy Yule season all,

The headers came back from their re-chroming.  Also had the exhaust retainer thingies zinc plated.



Silencers should be ready after the festive period.

Cheers  Geoff

Very shinny!

The s/s replica Seeley silencers arrived today.  Not a 100% copy but pretty good.





Still some minor fettling to do but they went on fairly easily.  I might get to ride it tomorrow 

Cheers  Geoff

Glad to see you still cranking on refreshing this awesome bike. Everything about this bike is so cool. Looking forward to more progress.

Why not just make the speakers go to 10, and just make 10 a little louder? llol


Bike sounds real nice. So what is the story with these seely bikes? Are they more race ready, I've never heard of one.

Colin Seeley was a racer and frame builder.
Made about 300 frames that take a SOHC CB750 motor.  He is more known for his Norton and other british powered bikes.

Hi Bronco,

I have been trying to type a response ref. Colin but twice now the page froze and I lost it all.  just Google/Wiki "Colin Seeley" and you will see what he was about.  Suffice to say his frames had a sublime reputation in their era.

This is my other one, for the Suzuki T500 engine, posed alongside the 750 (pre new exhausts):

This is bike of the month material. Can you post some completed shots?

Hi,  The bike is basically finished as it is pretty original and as they say "it's only original once"  .  There are quite a few paint defects due to it's time in storage but I can live with them.  The engine may need a top end strip to re-grind the valves and give it a de-coke but that can come later.  I'm just dying to get a few more miles on it, roll on spring .

Geoff,

This bike is a beautiful survivor.  Since it's now a runner with the exhaust, I think it's eligible for BOTM.  If you could post a few photos of the entire bike together, I'll nominate it myself.  That's how much I like it!

I'd vote for it! I don't think I've seen a Seeley since I was a kid! Amazing that you have one for the Titan, too: those 2 bikes in that picture were the #1-#2 racers at most of the tracks I knew. The 50HP Titan, 150 lbs lighter than the 750, was a real beast to beat!

The horn: if it is the OEM horn, they rust inside and the coil stops moving, if not used once in a while. Very common!

You must be much younger than I thought, Mark!

Geoff,

You have been nominated and seconded for BOTM.  Please post that you "accept" the nomination in the following thread:  http://forums.sohc4.net/index.php/topic,154857.0.html

Yeah this is a beautiful survivor!
Sounds epic too!

I couldn't resist, another small clip of aural delight, dang this thing is going to be loud, better dig out my earplugs    (note the apt comment from the radio at the end lol )

A rare sunny winters day so I decided I deserved a full English brekkie at Merkins Farm Café.

Beautiful bike and classic English sunny day

I am still checking out the engine on my bike.  The exhaust note is not quite right to me and the #3 cylinder is running rich (not firing every stroke ?), it seems the #3 is being a bit lazy  .



I am curious why #3 and #1 compression readings are down on #2 and #4, although they are within the range of acceptable (just).  This could be due to the long time the engine was not running so may improve with a bit more use (I have only put 150 miles on it since I got the bike).  I would guess a top end re-build/service is in order but I'm not sure it is essential at the moment, any thoughts on the best way ahead appreciated.

Cheers  Geoff

The compression numbers are within 10% of each other, so that's "acceptable". #3 obviously has some issue with its burn, #1 looks a tad off too. Have you bothered with a leak down test yet? And I would also expect as you do, some improvement with more miles.

Forgive me for not scrolling back, but have you adjusted the valves since getting the motor running? This may yield a bit better result also.
