Here is the Avanti TT3 Ci that I have been playing with for a good few months this year.
It has a completely New Cylinder and is fed via a cast reed block welded to the crank case incorporating an RB reed. The crankcase throat also has a cast block welded in to take the Third Transfer Port. The Prototype has been running around the country side for a few weeks. The price has not been 100% set as yet but the first 4 ordered will be finished by the end of November. Power spread is brilliant.
Reed Block might well be sold separately as a DIY kit, Prices will be made available in a couple of weeks.
You can see a video on my Face Book page of the engine running. RM......Now added here too

Looks great,
is there any chance for us who don't use facebook to watch the video?

Thank you Ron.
The exhaust also ain't looking bad ,
I wouldn't mind to use one on a future project.

rough idea on price give or take a hundred?

Bikegunn,
It is on this page + my own face book page

Very interesting development there Ron.
The engine sound 'responsive' in the vid. .
It also raises a bunch of questions in my head
Given the ammount of crankcase welding involved, is this still based arround a 58/60 stroke x 107/110 rod crank format?
What is the crank web layout for the case induction tract?
Does a 'piece' really need to be welded to the top of the top of the crank mouth for the 3rd. transfer, as opposed to a simple 'weld build'? (costs presumably?)
Could I still fit a 100/90 x 10" tyre?
Which gear can it tackle 'Caterham Hill' in (at 4am traffic forgiving)?
Respect

Engine Specification as being used on road bike:-
Bore 70mm stroke 60 Full Circle Crank
gearbox : Li150 46 / 17 sprockets giving 4.6:1
Exhaust: NK Road
Clutch : AF 6 plate cassette Road
Your questions:
Given the amount of crankcase welding involved, is this still based around a 58/60 stroke x 107/110 rod crank format?
Yes
What is the crank web layout for the case induction tract? As Above at the moment
Does a 'piece' really need to be welded to the top of the top of the crank mouth for the 3rd. transfer, as opposed to a simple 'weld build'? (costs presumably?)
No but less weld means less distortion, nothing to do with cost
Could I still fit a 100/90 x 10" tyre? I have not tried one but it will fit
Which gear can it tackle 'Caterham Hill' in (at 4am traffic forgiving)? Which do you mean, A22 or the hill from Caterham Rail Station to Caterham on the Hill? not taken it up either, tell me which one & I will try it.
Modifications still to be carried out: Shorter inlet manifold, Indian GP 200 gearbox ( has closer 3rd 4th gear)
New Reed Valve Block tighter fit ( less weld filling) will be at our machine shop next week together with the cylinders, all heat treated.
