Hi People,
              Is there anyone, UK prefered, making a replica Laverda/ Egli frame kit for 750 cc Twin any details or a  contact would be of great help. Fingers crossed.
Thanks for Looking

and scaffolding.

Mr Egli is known to have made about four frames for the 750 and (under license) in UK a now retired person called graham Binnion also made a few, so there might have been six or seven genuine EGLI SF's/SFC's, There have been many copies made all over the globe of the Egli chassis to house all manor of engine units, Laverda included, Egli has sued about a dozen of these copiers with varying results and more exist , for example Moto martin made two for triples, when the Egli chassis was not even remotely similar to what they normally do.

Mr Egli rightly thought that the suspended 750 Laverda twin would be a great example to build into one of his chassis's, suspended in much the same way as the originator for his hill climbing competition days ,the Egli Vincent, the problem (with the Laverda twin) was one of vibration, not a worry for a 2 or 3 mile uphill blast, or even a 10 lap short circuit race, but as a saleable "road bike" kit the weight and gauge of the original chassis is needed to damp the vibration, the bare Egli chassis weighs only about 14 lbs (6.5 kilo's) and I have a picture of me holding mine up for the photo hanging on my little finger, but vibration is severe, I rode the bike to the IOM in 79 and 80 and the 220 mile journey from home, actually cut a trough on the underside of my riding boots of equal dimension to the foot pegs, strangely though my rump was comfortable sitting on the bare aluminium Godet/Genoud replica whale tail seat that I had made for the project.

So the long and the short of it is, vibration, can you suffer it? nothing ever broke off of mine, and much of it was self fabricated (tank/seat/side panels/ swing arm/forks/mounts/ pegs/ brackets etc) and adapted to  my needs and desires, but after two years road riding I retired her and she became a race bike/daytime road bike.

To properly answer the question I don't know of anyone making replicas in the UK, one is already listed above (but not UK), Egli themselves (Fritz is now retired and the business sold and strangely not to his son, who I met during an Amicale rally there a few years ago). Under the direction of Fritz no details were ever deleted and you could order any frame that had previously been made, or (at great cost) a commission for something not done before, under the new ownership ,although Fritz is still a consultant, I don't know, but what I do know is that if you order an Egli Vincent chassis from Egli themselves it will be made by Patrick Godet in France, he might make you the bare chassis for your 750, never hurts to ask.

In short Egli have been a victim of their own very simple design, originally, no bent tubes were allowed in his design, and just CDS steel used, no fancy high carbon stuff, the 4" top tube being the backbone that it all hangs from, it would not be hard to make one, excepting (maybe)  the swing arm which used oval tubing that may not be available.
I wonder if Grahams jigs still exist and if he would part with them, from what I can gather he is rather reclusive these days and does not show any interest in his former profession, so maybe they have already been scrapped

Had a similar scenario with the Mkl Saxon/Motodd frames Clem - as they are much lighter - the vibrations were more noticeable - fortunately the 120? series came out and we used that kit to rubber mount the engines - not really an option for the Sf motors. - but a 270? conversion would help.- Regards - Phil
 
270 conversion for the "Clegbiverdason" (Clemans/Egli/Binnion Laverda/Wilson)  ????
now theres a thought, since the motor will have to be opened up before I run it again, as I built it in about 1982/3 and I know my skill levels are far higher (and my finances stronger) than in those days, it would make sense to do it, there are things on the chassis, that when I look at them, I think,  "did I really do that", thoyughts like ,that looks so heavy, carrier brackets on a race bike, who welded that, what did I do that for, but some things just have to stay, if they are proven and work well, because what you did when you were a skint 25 year old, you cannot do again, and I have very happy memories of most of the build, such as turning the eccentric wheel adjusters out of a dirty great lump of scrap cast alloy, which leaves the porosity holes showing on the exposed bits, I could make new one from Dural bar, but for what purpose, looks alone??? nahh, I did that and it stays.

Rubber mounting of a 750 engine in an Egli (style) frame will give problems in the handling dept.

My Egli doesn?t vibrate more than a regular 750. I have run it with the original engine (small valve head) and currently run a 1974 SFC which feels very similar vibration wise.

Now the CND 850 with its 270 degree 850 engine is the big vibrator. Beyond 6000 rpm is no go area, terrible. Going to have the crank re-balanced, hoping that will improve things. Balance factor 60?

Hello just joined forum
I found a Egli Laverda 750raced in the 74 tt by Peter Bates and put on the road in 1978
Last on road 1983 
Bought from a deceased estate

I use 60% on the 270 engines, seems to work fine

And get it as true as absolutely possible.
 
Well the crank was a bitch to get true, Lee, possibly because it's a combination of light SFC centerpiece, triple inner webs and lightened SF outers. It's true now and rebalanced. Don't know the exact balance factor, but if I remember correctly he mentioned that it was 55, Red.

Result is very good, it's happy to rev much higher, but there's still a nasty shake, which very much feels as if the engine has loose mounting bolts, which is not the case. Must study the engine mounting, nice job for the winter. If things won't improve I will bolt the engine in one of the standard Laverda frames just to feel the difference.

Think he'd copied my idea Marnix as i sold some of my SFC style centre pieces in the nineties - my 270? motor has that system in it and was easy to true up - did have a glitch with having to add heavy metal to crank to get right balance - vibes not an issue -  although it's in a standard frame.

Will be very interesting to compare, Marnix. I've shied away from a light frame for a road bike because I believe the water piping frame is a very effective vibe soak. What's the Palmelli like, Phil - being a lightweight frame as well?

  The ( Stainless steel) frame isn't that lightweight I think Quentin - I didn't build the crank in it so don't know the spec - I haven't revved it too high as yet - but it's very smooth up to at least 6000RPM (not too sure tacho is accurate either). It does have a huge amount of grunt  at low RPM too. I will probably run a std motor in it  for a while and strip the original when my new
heated workshop that is attached to the house is finished. - It's finally underway and means I wont waste the winter cringing indoors -  Builder is a bit of an old dog though  :o- Regards - Phil

hope he doesn't do a "rough" job Phil and that he keeps his mind on the job and not his  left at home "WAG" hopefully you have a goodun there and will "winalot" without too much time "pausing" for unearthed bones
