I received a letter confirming the authenticity of my bike from Colin Seeley today.  A great addition to the bikes history and well worth the donation to the Joan Seeley Pain Relief Trust.  Thank you Colin  8)

Thanks Trigger,

During my searches on the subject several times I have seen the "use genuine Honda headgaskets", I'll do the same. Although I can remove the top end whilst the engine is still in the frame on the Seeley so not so much work compared to having to remove the engine to replace a head gasket.

I'm still trying to work out what function these "pucks" perform but obviously they are needed.

Cheers  Geoff

Hello Roy,

The CruzinImage products do seem to be bit hit-or-miss.  Some of their kit is good, others.....questionable.  I like the offering from Cycle-X but their shipping is more than the price of the gasket kit.  I'm not in a rush, the top end re-fresh will be a winter project.

Cheers

Hello,

I intend to lift the head on my 750F1 engine to re-lap the valves to address a small issue with low compression readings.  Is there a favoured brand (apart from Honda OE) for a top end gasket kit.  I do not have adequate knowledge to order all the gaskets, O-rings etc. individually.

Cheers  Geoff

Colin Seeley was kind enough to sign a copy of the Classic Bike magazine feature for me.  A nice addition to the bike history, I think he liked the article too.

I have been offered a Cycle X 850cc piston kit from someone who bought one from the USA but really wanted std. pistons.  My apologies for asking but the "search" facility returns zero posts, even if I just put in Honda lol  ;D  I guess a glitch there somewhere.

The kit is destined for a std. F1 engine but I am interested in the pro's and con's of the cast 850 pistons vice a forged 836cc kit (Wiseco etc.).  If I do go big bore it would be sensible to add a cam and also flow the head etc.  I don't want to go so far that I need stronger rods but upgrade to valve springs/retainers and barrel studs would be OK.  This is not for racing, a stronger road engine is the goal.

Thank for any insights

Cheers  Geoff

Hi,

The feature on my Seeley Honda 750 was published in the October Classic Bike magazine. A good write up from Gez Kane.  Colin Seeley confirms that only 6 bikes were "factory" built by CSRD so it makes my bike a pretty rare example.

Here is a link to my flickr album page.  Select a photo then If you go to the bottom right of the page you will see an arrow pointing down.  Click on this and then "view all sizes", you then have a choice of photo sizes, Large is OK to read (you don't actually have to download the photo) https://www.flickr.com/photos/zunspec/albums/72157671221523016

Hello Andy,

Regarding the Seeley exhaust set-up, the sound from mine has (to my ears) an odd harmonic to it.  It's as if the engine is not firing as it should but then I am more used to the sound of 4-1 systems. Is it the result of the way the cylinders are paired up, not something that occured to me.  At 6000+ rpm and a WOT it sounds absolutly wicked mind  8).

If you have followed this post post from the beginning you know that this Seeley is almost pure period Seeley apart from the silencers and brake lines.  It was "factory" built and as I had the ear of the man himself recently I asked how many of the 300 odd frames he actually assembled in house.  The answer was "not very many" as contrary to my previous belief that Honda supplied the necessary parts Colin had to buy a complete doner bike and transfer the parts just as all other builders had to.

Your CR750 is gorgeous, is it raced with CRMC? . That 836cc big bore kit on your website also looks mighty tempting but I am spending far too much on my own race bike (Seeley T500 replica) to afford it at the moment  ;D

Cheers  Geoff

Very nice indeed, but oh so fragile the bevel.

Hi Mark/hairygit,

Unfortunately I only got to ride it to the MOT shop and from there back to the owner.  All on 12 year old tyres so I could not give it a good blast  ;D.  I do know that the first owner road it to several events in Europe, when I first got it the pannier bracketry was still attached.  He even did a bit of club racing on it I was told.  So it was obviously moderately reliable.

Cheers  Geoff

Speaking of the 900SS, I had this in my care to re-commission and MOT

Me again  ;D

I just received this email from Colin Seeley, great news.

Hi Geoff

The bike looks excellent and from my records I can verify its originality. I Look forward to receiving your cheque and I will then send an official verification letter in due course, together with the book.

Kind regards.

Colin Seeley.


The cheque mentioned is a donation to the Joan Seeley Pain Relief Trust and I ordered Vol 2 of Colins autobiograpy (hopefully autographed too)

Cheers  Geoff
