I mocked up the exhaust from the turbo outlet today - again it worked fine with the standard random bends I bought - lucky !!

 The position of the front bends were finalised and it looks very neat - I just need a welder now !

I now have an idea for the final design / layout of the auxiliary oil pump and oil cooler.

I hope to order all the hoses and fittings in the next 12 weeks. First I must get the bike off the bench and on to my bike ramp so I can see all around and not just one side !

I WILL drive the pump from the alternator side - as I realised that the pump spindle must have a small amount of oil to prevent possible seizure.

Also I am thinking again about the turbo system. I prefer suck through - with the carb before the turbo. This does not change the layout, but makes installation more simple for the plenum and various sensors will not be required. I am familiar with this system - used for many years on my Race and road cars. It does mean I need a turbo unit with a ceramic heat seal.

Over the years I have had many speciality springs made and latterly for www.ramshox.com. - site is being replaced - but it will give you an idea. 

I will be needing upgraded items for my Glemseck project. 

Many of you will know that Redditch is the spring capital of the UK - remember "Terry's Springs" ? You will if you've rebuilt many Brit bikes -  best valve springs available - allegedly.

My tame spring man will make me just one set if I ask nicely, but as with the other springs now available from Realm Engineering, makes sense to have a batch made. Gets the cost down and everyone benefits from  a bespoke product at an off the shelf price.

So, any interest ?

Particularly those peeps with the dreaded "air assist" front forks !

I did a replacement progressive fork spring for my Vindicator Cafe Racer [ Yamaha TR1 based }and it transformed the handling - not to mention a simplified set up and maintenance. 

So here's what I plan to investigate

Progressive fork springs
Uprated clutch springs - say 25%- 30%

Anyone interested ?

I just paid a visit to my tame spring man.

Absolutely NO problem. He has ample stocks of the correct grade high quality spring wire to make both clutch and fork springs.

I WILL go ahead with the clutch springs anyway. I need to order 100 springs minimum, which is only 20 bike's worth ! Just as a matter of interest I'll check the price availability of OEM clutch springs.

The fork springs are another matter, as the unit cost is significantly higher - not huge, but I have to be certain there is interest before I commit to placing an order. However, I expect a unit cost of less than £75 / pair with an initial order of 50 springs.

Like I said - any interest ??

I've been busy looking after an old pal who has just had major surgery for cancer for the past 8 weeks or so - he had his last major operation a week ago and it was 90% successful. The future looks good.

That means I have had no time for my own projects with twice daily 40 mile round trips to the hospital to take his wife for visits.

So, I can get back to my projects now.

The good news is that on a recent visit to my old workshops to see my pal that took it over, he volunteered to have the KZ up there while he made various spacers, fab, etc. He makes parts for a couple of major classic car parts suppliers and has all the relevant machinery and skills to sort out my odd jobs.

First job will be making the spacers to fit the front and rear Borrani wheels so that the rolling chassis can truly be "rolling" ! Might even be able to get the high level exhaust system fettled and at the very least - tacked.

Plan is to get the bike up there at the end of the month [ he has a big job to complete ] and work can begin to take me to the finishing straight.

[font='Nunito Sans', arial, sans-serif]While I was sitting twiddling my thumbs waiting for my pal to clear his work and get the chassis up for the machining etc., I decided to look again at the intake / exhaust as this will be the last opportunity until he has finished his part of the work.[/font][/color]
[font='Nunito Sans', arial, sans-serif]Anyone who followed the early embryonic Glemseck ideas, will remember that originally I wanted to use an Eaton blower. When I offered mine up [ 1 of 3 ], it was obvious that it was plain too big enough to fit without butchering the frame. Also – as I thought – the drive from the alternator side rotated the wrong way for the blower. Blower clockwise.[/font]
[font='Nunito Sans', arial, sans-serif]Of course when I found out I was wrong about the engine rotation – I had already moved on to the idea of a turbo. I have never made a secret that I am not comfortable with turbos ! Yes, I KNOW all about the benefits – but I’m also aware of the drawbacks and having built 5 or 6 blown twins in the 60’s [ Shorrock ] that would be my preference.[/font]
[font='Nunito Sans', arial, sans-serif]So, why bring it up? Well a blower I had already sold to a guy was returned to me as “the wrong one” – glad in a way as it was without doubt the best s/h Eaton I’ve owned. Absolutely NO snout play and excellent rotors.[/font]
[font='Nunito Sans', arial, sans-serif]Since I had it back, I never even unpacked it [ 6 weeks ] – until today.[/font]
[font='Nunito Sans', arial, sans-serif]“Well I’ll be blowed” [ forgive pun and insert your own expletive ] – ” It’s more compact than the other 2″.[/font]
[font='Nunito Sans', arial, sans-serif]Whizz out to shed, remove exhaust and Weber and offer the blower up ……………….. yes, that’ll do nicely.[/font]
[font='Nunito Sans', arial, sans-serif]At a stroke that relieves me of sorting out oil feed for turbo [ blower self contained ], and electronics / carb – and the main stumbling block, getting a turbo unit with the old school carbon seal. That will make the installation so much simpler, and relatively speaking the tuning set up far easier. Of course NO turbo lag, something I was a bit concerned with a twin – and boost from idle.[/font]
[font='Nunito Sans', arial, sans-serif]As I was going to have to devise an oil pump drive for the GSXR oil pump anyway, I’m no worse off AND I’ve already got all the pulleys.[/font]
[font='Nunito Sans', arial, sans-serif]One very happy Beachcomber.[/font]

Seems I have the "big" intake manifolds - and now I've checked I find they are spot on to use as a base for the intake from the blower. Two tubes will come off the intakes to a circular [ oval if I can find the material ] plenum which will then shoot off with two curved tubes to the blower outlet.

I have now discovered an even more compact [ externally ] Eaton, with the same capacity. Checking that out now - if that works, that'll leave me 2 to sell off ! 

OK I have been very quiet for 2 months !

A very dear old friend has been recovering from a serious Cancer operation - and also my youngest Daughter got married ! A VERY big wedding and a lot of planning and Dad running around.

Wedding is over now [ 9th. Sept ] and just my eldest Daughter's 50th birthday this weekend - and then I have my life back !!! 

I have all my parts ready now, and I collect my new twin plug head in the next 2-3 weeks [ Thanx to KK ]. 

All the plans are now OK in my head and I am happy about the direction for the project. It will definitely be a 60's Cafe Racer style [ my era ], and again - I have all the relevant parts.

I hope my German cousins will indulge me for posting photos of my beautiful Daughter. !

Hi TJ,

very nice pics, thank you !
Good looking family and very dapper clothes !

Cheers, Michael
