So started my first fit for the left side exhaust pipes. I ended up using the old front clamps as the new ones appear to have quite tight holes causing me difficulty on number two front pipe as the studs that were Helicoiled are at a very slighty wrong angle.
Quite happy for now to use the old clamps that I had previously  cleaned &  painted.

I fitted number two front pipe first  as its the lower silencer unit. lt lined up quite nicely but number one upper silencer was not wanting to fit with the rear joint miles out. After several attempts and a tea break I tried a new idea.

I fitted the front pipe end first with the clamp in position but not the two collets. With the mounting bracket removed I fitted the connector pipe in place (not tighted but clamp in place) then slipped in the two collets on number one exhaust and nipped up the two retaing nuts finger tight. I then slipped the mounting bracket in place nipping up the silencer nuts and the top hole bracket just slotted in place. I used an old bungee strap on the end of the silencer to keep the connector in place rather than clamping it up.

Tomorrow i am minded to make some minor adjustment to the slotted holes on both brackets so that the front pipe sits more freely into the cylinder head. With a lot of faffing about it took me almost two hours to fit one side including tea break.  So far I've just fitted the left side exhausts - I still need to do a little fettling as I want to make the front pipes fit better into the cylinder head - I might need some wider slots in the top holes of the brackets to allow the silencers to move a mm back. Just to release any unnecessary tension.

" Wear limit spec is 70mm. Does anyone know what this measurement is with a brand new chain? "
And the answer is 63mm. Brand new chains and tensioner from CMSNL.

My new 500 came with them. Don't remember replacing them, but probably did as bike was used year round.
Spent a fair few ££ buying up a set from three different sources in the last few years.

I used the kit from Pyramid Parts and whilst it did fit there was only 1.5 turns on the castelated nut. I contact Pyramid and they requested photos and these were duly sent with the measurements. Pyramid admitted the kit was not suitable for the 400/4 despite their listing stating it was and gave me my money back. This was the same kit many have used on here. Pyramid agreed with my findings that it could be dangerous.
I bought a set of caged ball bearings in the end and they fitted perfectly using a 2mm shim on the lower yoke.
I have contacted Pyramid a couple of times since to request an update and I also voluntered to try the stepped bearing they were proposing but they told me they are currently speaking to several restorers of these machines to obtain a solution. Needless to say I had a pig of a job to get the taper races out of my newly powder coated frame!

I believe a member here fitted a Pyramid kit to his 400 without issues I think it was oldchuffer? Anglesey way. My 400 ended up with the caged lower ball race and a taper top as the none pyramid kit left not enough  top thread.

Thanks for all the input and suggestions. I will tap out the brake bit and the bearing cups and whilst Im at it will have a go at the shock bushes and see how bonded in they are. I will get a kit of the old-style ball bearings and races as if it worked for nigh on 50 years then thats going to see me out. Mike

when I stripped Lazarus it had Taper rollers fitted and they are really difficult to remove as they are the same diameter as the headstock tube so no lip to get a drift on to bash it out. In the end my mate who has welding gear ran a bead of weld around it and it just dropped out. I bought some of the caged ball type but was not happy with the quality so chucked them in the bit and went for original races and generic ball bearings.

Misc / Open / Thanks are overdue from Lazarus

Many of you have followed my journey with my 500 four named Lazarus. He is now roadworthy and undergoing final fettling and still resisting but gradually getting there. Was just thinking I would have not got here without the help of this forum, if only for the encouragement and banter! Lots of you have contributed spares and advice over the last 2 years, Nurse Julie and Graham with parts and machining work, Bryan who supplied stuff at low cost to help the budget, and many others with bits along the way. A big thanks also to Oddjob (Ken), no longer a member here but donated lots of engine parts to the cause, a star! So a big big thanks to you all from me and Lazarus, have a great day.
regards, Mick
