Lets build a SOHC for less than a grand

[Laverda Dave]

Great, thanks Julie 👍

[Trigger]

A bit more done: All electrics tested and working and re built carbs on.
Things to still do:
Sort the front forks out, as I used a pair of 341's which are about a inch and a half too long. I measured up for the first design to have them coming through the top yoke with clip-ons on the top but, went for the original look in the end.
Fit the donated Delkevic exhaust.
The tank is finished and will be on its way back from Ireland.
Julie has started cutting up foam for the seat and will make a cover.
Still have to buy some brake lines.
Fit the caliper pistons, seals and pads.

Put some oil in and it is finished.
Yes, I am over budget but, if I took the good wheel rims that I was offered and not paid out for new ones , I would of been under budget

nice one trig

[Trigger]

Still have not finished this off yet.
Still waiting for the paint work to arrive, which is on it way.

I have lost count on how many times I have had this front end off. finally happy with how the right hand arm sits now. Took about 2mm off the mounting lugs and then had to shim the bottom one out by 0.30mm.
A down fall is you have to let the tyre down to now get it past both the caliper arms .

Got some Stainless steel pistons yonks ago which had the right dia but, too long so, a quick skim in the lathe and found some old stock vesrah pads.

It's coming along nicely. I love the tank and side panels colour. Best of luck with the rest of it

Just found my old Cibie headlight and on first look it appears to be identical. Mine was listed as a Z beam, there were others which looked the same but didn't have the same beam pattern. Mine is stamped on the front of the glass with Cibie with IODE just under it. Just to the right is HCR just above a large E2 with 175 to the right of that. Just below that is an arrow pointing to the right and 112 just below that. The last one is right in the middle at the bottom with what looks to be a Delta triangle above another E2 and that above 589. I can see the reflector dish in front of the bulb but all markings on the reverse of mine have gone as it was sprayed with zinc paint to stop any corrosion. Have you tested it yet to see how it performs?

Some questions which occured to me as I re-read the thread.

On page 11 just below the pic of the Honda grinder what exactly are you doing. It looks like a machine for refacing the surfaces of the valve but I seem to recall the Honda grinder has 3 type of stones you fitted which reflected the angle you wanted to grind on the face.

Have you fitted the coils backward as it looks to be the case, nice to see someone has actually routed the leads correctly for 1 and 4 cylinders, on the 550 they are meant to be routed over the engine and clipped to the breather cover. Most seem to just dangle them over the engine so they approach from the front of the engine rather than the back. And before you all say I'm wrong please consult the wiring/cable schematic for the 550 and you can see them on it. True the coils face forward but I found them easier to route with them going backward and it also protects the leads from rain etc so they short out a LOT less.

Going very well Graham, not sure yet on the state of my 500 bores as not started dismantling the engine yet but if it needs a rebore I'll send it down to you.

Yes, 3 angles on grinding the valve seats

Did this ever get finished Trig?

[Bryanj]

It was when i saw it last year inbetween lockdowns and looked magnificent

[Nurse Julie]

Yes Roy, Trig finished it early last Summer but I didn't get round to making the seat until January of this year 🙄🙄🙄

It's not on the road yet as I need to sell off some bikes, starting with Grahams 750/4 Mongrel, RUF, which I will put up for sale probably next month, as we have run out of room for parking the bikes that are on the road.
Here's some pics 😁

Very nice job as usual. Is that the same exhaust as on your mongrel Julie.

No Roy, Millie, my Mongrel has an original Yoshi on it, Graham fitted a Delkevic to this one.

[royhall]

Usually Delkavic means noisy?

It's a lot quieter than my Yoshi 😊😊😊😊

[royhall]

I'm surprised at that as Millie is fairly quite. Now the big question, was it under a grand?
