Looking really good Roy. Can't wait to see your bike at the rally. Have a good ride up the island.
Just a thought, Davidd would know, Didn't some of the Egli twins not use the rear head fixing, For vibration reasons ?. Cheers Bill.Thanks, that is one of life's choices, putting the time into your project & taking 30 years as I have, or doing a "cheap quick job" & living with "compromises" but getting some enjoyment out of the finished article.
I have now become impatient, old age & knowing that time is running out, so currently leaning more towards "quick" to get some use out this before I'm too old to kick it into life!
Down Under, we have never had the luxury of an after market supply of items such as seats, the country is too small to support it, so we tend to make stuff like that. However, the internet has made life easier, I bought the Suzuki handlebars off our local auction site, then binned the modern bar end weights because I insist on having my favourite mirror there instead. So, the vibrations are not so much in the bars, they are rubber mounted in the shortened Benelli Tornado forks, but more in the pegs. Luckily, at 60-70 it is smooth, which is where it needs to be.
I resealed the 2 leaking push rod tubes last night. A run out with the local Vintage Car Club M/C section this morning will prove whether it is fixed or worse.

Ah - more Kiwi ingenuity.Yes, Air New Zealand say there is no problem, they will hang it under the wing of the B787
Morning David, So it had nothing to do with vibration, I thought I had read you have to alter the balance factor with some fittings, Like Norvins and when you fit a Vin' in a Car type, I have never done this so it's just in my head !. Cheers Bill.Bill,
I have seen some frames that are like Roy's, the welded plates are there, but no bolt hole. I don't have any problem with Roy's comments. I have a non-slotted hole in EV4, but I never seemed to have an expansion issue, or I did not notice one.
When I started building frames it became evident that it was impossible to fit an newly built Egli frame to any or all engines because the the dimensions of the engines are all different. The stock UFM attaches to the two head lugs only, but the Egli frame attaches to the two head lugs and the swing arm bolt. That is impossible to do without a good measurement of the specific engine that is to be fit. If an engine fits an Egli frame off the bat it is like winning the lottery. Godet can do it because he is building the engines and the frames at the same time.
One of the possible solutions to making a universal fitting Egli frame is to not drill the hole for the rear cylinder. This allows a "fudge" to be done on that rear lug hole in order to custom fit the frame. I made a bolt on jig that allowed me to drill the rear hole after mounting the frame That is a possibility. Either way is probably fine because the full Egli frame attaches in three locations as I mentioned. Omit the rear head lug bolt and it is still attached in two places.
In the end, I eliminated the seat portion of the Egli frame on my builds and built my frames like the original Vincents with a UFM and an RFM. This eliminated the problem with lining up all three holes to the engine.
