Slimline Norvin twin ?

Which ever way you go try not too bodge up a good original Featherbed frame buy cutting or changing the shape, work around it, sorry I just love my Featherbed frames, Wideline and Slimline, I have seen a Vincent motor in a Wideline frame but it was cut and changed, I have also seen one where the bottom rails were completely cut and reshaped, I have also seen one where the bottom rails were completely cut off and the motor used as part of the bottom frame, that to me completely change the purpose of a Featherbed design same as when people try to isolatic a Featherbed frame.
Then there are the replica Featherbed frames with more height to fit bigger motors, I was thinking about building my Slimline frame with a Harley 1200 Evo motor but fitting it would have to change the frame by cutting and reshaping so that idea just got out of my head, anyway good luck be a very interesting build.

PS don't worry about Al, he seems to be a nice person but he don't build road going bikes for the road, everything is race, race and racing and it's been sometime since he has raced and he looks at things differently to others who are in the know.

I think a 5 speed Harley Sportster might be better than a Norvin. My brother has worked on a lot of Vincents - every bolt is a special. Phil Irving was involved in designing both Velocettes and Vincents. All other British bikes are easier for building hybrids.
I was offered a Manx rolling chassis, which had a KTT Velocette motor installed. The parts were good, otherwise it was a nightmare.
I once rode a Vincent which had a Velocette swing arm grafted on. It was good to ride. It was on 11 to 1 comp. with methanol fuel. I wondered where all it's go was coming from. It seemed to be firing once every 30 metres.
 
The frame on an S1 Buell is almost sensible. But to me, it still looks wrong. The Harley 750 TT racer was OK, but still had a horrible frame. Godet and Egli had much better ideas for V-twins. In Australia, we can get away with a lot with old motorcycles - we have club registration for vintage cars and motorcycles. But for most things major, we need engineers' certificates at $2000 a pop.
A few years ago, one of the hot rod kids spread himself and his mate all over the landscape. That changed the laws.

No more special bolts on a Vincent than on any other brand.
A Vincent hybrid isn't more difficult to build than any other brand but surely it's more expensive.
11:1 on methanol and probably big carbs and cams and you wonder where the go was coming from? Really?

Understood.
I am not going racing, just a good road bike fit for highway use .
Reg. a Egli, With the Dutch RDW (Rijks Dienst Wegverkeer)- it is virtually impossible to get a road permit/licence on a custom build frame that has not been officially imported and licenced here.
If you want to live with a bit more danger then use a licence from another bike, Ha!
But when you end up having or making a accident and the numbers get cross checked you are liable for e-v-e-r-y thing.
If you want a custom made frame like a new Egli you need to get your bike tested as if it was a new product as factorys do, only for those with deep pockets .
Thats why I will use my Slimline, it has a period licence.
Frame number is 'guiding' over here, engine does (up to a point...) not matter.
German TUV is much strickter, changing a muffler -for instance- already makes the bike illegal.
They (Germany) also have a yearly test to see if it still comply's, something that -actually- has been arranged in EU fashion but every country is free (....) to fill in the details.
For the time being....no such thing as a TUVtest or MOT over here for motorcycles.
And if that shit does hit the fan, it will only be for the modern ones, after 1980 (or so) .
I like to keep it simple, use my Slimline.

This makes a lot of sense, given that the Norton frame expedites registration for you.
The worst part of building my modern type Egli was dealing with the registration process. I think the rules have now changed here and it is even more difficult to deal with that now.
The way our rules are now, I suspect that even a Norvin which utilized a previously road registered Featherbed frame would be very difficult to register here. This is because of the extensive modifications done in order to make a Norvin out of a Norton.
Here is my (thankfully) road registered
1360cc bike. Someone suggested that I try getting it registered as a Vintage collector bike in order to get lower insurance premiums. I won't be doing that as that would be pushing my luck and it could really open a can of worms.

Slimline Norvin twin ?
