I used to swear by BPVF7 Ted, there were so many detergents in it that you could eat your dinner off the inside of the engine, that’s if you didn’t mind the taste of oil that is.

Yes, I think in the early days of good oil detergents some brands went a bit overboard!

On the old BMC A series engine the development of good positive crankcase breathing systems did stop a lot of engines gunking up.

Hi all

Picked up cases tonight

Really please with them

A few up close pics







As you can see in the third pic the cleaning process is very kind/ gentle on the cases as you can still see the “exposed” original faces as the process will only remove oxidation and dirt.

Will next week get the barrels done so they are nice and clean ready to send out to be bored out to 460cc

Next job (now cases are back) is to record all the crank marking then mic up the crank and sort out all the shell bearings so I can do a plastigauge fit with the new shells and clean cases.  Then once I am happy I will paint the outsides and then start the reassembled of the bottom end

Also in parallel got my oil cooler kit in order so I can sort this out as a separate project on the on the road bike while I am awaiting parts for the “on the bench” engine build

Catch up soon

Best wishes Al

Hi all

Well that’s the planned oil cooler mounted

Was not a lot of space and needed to manufacture a bespoke mounting and remove a couple of mounting brackets on the oil cooler itself that were not needed






Also got the filter mount sandwich plate



Now just need to sort out some bespoke feed and return pipes and this part of the project is done

Will look very “cool” once finished with all the braided stainless hoses

Catch up again soon

Best wishes Al

Hi Oddjob

Filter sandwich plate was from D & M Engineering




As for mudguard clearance loads of space and there is more risk of mudguard touching headers due to me fitting a generic mudguard from DS but got 40mm preload spacers fitted so front end is a bit firmer

It’s not a replica exhaust but a stainless Delkevic system that comes supplied with the plain clamps

Fits a treat  and you also don’t need the split exhaust collets  either as the header pipe has a flange welder in place that the clamp used to seal the exhaust into the exhaust port

Also down pipes just slip into collector and held in place using springs and no clamps

Good value for money and sounds rather “rich”

Thanks

She certainly has come a long way in the last 18 months

Just need to drop in a rebuilt 460 motor and she is all done ( or maybe not) as there is always something else to tweak

I like the twin disc conversion but way too difficult for me as I'm still very much a novice and don't have your engineering skills. I agree with what's been said OK it's not original but is still period looking. I love to see the originality of personalization.

Hi

Just a quick update on the thread

Planned oil cooler now all sorted

Sorting pipe runs was a bit of fun but a kit off eBay with all sorts of different end fittings sorted that

Looks the part and make the bike just a little different from the crowd

Now to start sorting new parts for the replacement motor

Catch up soon

Best wishes Al

Some good looking engineering here Alan, looking forward to see how it develops with the new engine.

Where did you find those lovely extra deep dome headed nuts on your manifold?

Hi Ted

Rs components

They are stainless steel

I will take a look and see if I still have eight left but no promises
