I started thinking about the of this project Summer by sketching working out a basic researching frame design sourcing and collecting the required to make a start on this project. There are so many parts required to be manufactured, the frame. Work started in 2011 with the frame

I blogged the progress on each area separately — engine. body. wheels.

What started this was simply finding a 2007 MV Engine on ebay for $1000 in 2010- who could resist. Now to do with a 750S F4 engine 125HP of intoxicating power. in our area have fabricated examples of the AJS Vee4, a 1904 Board Track racer and a series A — I am not up to fabricating an from an oil stain — so the MV F4 engine is a perfect place to

The project was born.

Arturo through his son Giovanni are still replica parts for MV’s out of After a month of I finally was able to have a full fairing set, tail unit and a set of their curvy megaphones. A promise of a never eventuated and I have now a 750s America tank on for close to what I recently a Norton Interstate gas tank

As far as the modern components go — I been collecting MV F4 parts various sources including and from Carl Giuffre CAG on the MV ( ). Carl supplied the that started all this. I now in hand all the required parts to the 750 F4 engine run. ECU, harness, all the relays, fuse throttle, radiator, fuel instrument unit, handlebar etc.

I plan to keep as of the modern componentry intact, to keep things simple. The will be to disguise and hide as of these items as possible.

Believe it or not, sourcing the gas has turned out to be the pivotal piece in able to start on the project. I am building a frame from shoe horning the 4 cylinder in and around a frame and tank has to be very challenging. Having the tank means the frame can be to suit see BODY WORK for transformation of the gas tank. One major required to the engine was to change the bodies from near to horizontal.

This involves new intake manifolds with Fabrication is well under way see ENGINE Blog

I sourced and brakes from Wolfgang Laverda Specialist in Nakusp. He the full set up including a new 230mm 4LS front brake, a Grimeca hub, alloy flanged and heavy duty SS spokes with a set of Tomeselli levers and rear-sets. Front forks, tree are from a 2000 955 Daytona 45mm Showa’s full adjustment. I have had under my bench for seven finally found a use.

The frame fixture (jig) was using a 12 structural channel and HSS following concepts from Moore of Euro Spares in On his web site he shares his vast of experience and knowledge with frame design and making (Thanks Mike if you ever this) Here is the link to his Tony Foale’s Motorcycle Handling and Chassis — the Art Science has also a useful resource.

Before the trip I had a quick session to see where the map was — the said the map was all F’d up extreme and rich peaks — he top bottom ranges to help for the Honestly it feels really to me — not overheating, fuel is identical to my 910R. The overall HP is about 25, which is not what I was for.

I have decided to the injector location, by relocating to the top of the manifold so will have a squirt down the intake. I am for at least 100HP at the rear This motor was dyno’d in 2006 at 110HP.

Once I have completed the then it will go back to the for a full session where the can build a proper map.

Gas is 180kms on 12 litres, around Tank capacity is 15 litres, 3 litres reserve, much than I was hoping, as the original was 19 litres before I guttted it for the pump and frame.

Being a Kiwi, we to do it all: I only out-sourced one build and the headlight rim re-chromed. total around $10K for the all the and it is essentially a bike that I never sell. A complete of love fueled by the passion for the MV Magni look. A lot of MV F4 owners on the MV wonder Why?

And why would I a F4. but when I walk into the and see that classic replica in all its my heart skips a beat and I say to “I own one of those?” There is really about the look of classic MV, and a one is so out of reach. This is built as an excercise in visual and audio I am so happy with the result.
