    The same idea has been ticking over in my head for some time now though I don't think the forum is the best place for it. If it is to really work it needs to stay on track: identify the skills and knowledge required, network to find willing people (through the forum), then take it offline and drive it in the right direction and just feed back updated to those interested.

    I want to build a 150cc V-twin... I'm dreaming but I'm thinking Baby Britten. I've just made contact with a guy who has a flow bench and is going to help me pull some ponies out of my CB200 motor, then once we reach the limits with that he has a friend who builds speedway motors that does all his own castings and all the rest except for pistons and valves. Should prove quite interesting and I'm looking forward to seeing where it goes.

    Hopefully this gets picked up and managed well so that something constructive can come from it.

    where opinion holds more weight than fact.

    It's better to not pass and know that you could have than to pass and find out that you can't. Wait for the straight.

    Well I use Openfoam CFD and play around with engines here in Japan ( and have been for years)

    With a v twin there is no need to reinvent the wheel , has been done before ,,,Ducati

    THOUGH

    Engines cost money ...quickly and expensively

    I just made some foot pegs and hangers, stress tested by FEA , and then a mock up using rapid prototyping , ( get it right first time sort of approach ) They were for my vintage race bike so had to be as light as possible , strrong as possible and ,,as cheap as possible ( cause it was ME whowas paying ) ...600 dollars roughly

    but ....... if there is a will there is a way ....

    outline the proposal and post it up ! I reckon

    Stephen

    ps you are right about the staying on track ......

    Edit: Fecking cool tho!

    you would be going backwards anyway
    thats a 4 stroke and the limit for f5 4 strokes is 100cc
    so you would need to find 2 of them and bolt to both the frount and back wheels giving you a 2 wheel drive F5 bucket

    now thats a project i would like to see get off the ground
