    I suppose it is fair to post a milestone in a project.

    Exactly six months on the road and Pumba completed a Far Ride and is now an official member of Farriders (1000klm in 24 hours)

    After finally obtaining some 32mm throttle bodies, I am working on different options of fitting them manifold wise.

    First idea is to use adapter plates allowing easy match porting.

    I think this set up could be prettied up and work quite well.

    i love the look of an EFI setup, i think that this will endup being something that i'd look at doing. Seeing as i dont think i'll ever sell my 900, its not going to be a waste of coin.

    Still loving this project, keep it up!

    You sure do enjoy th tech' side of it all, th bike looks good and it should fly with your mods. Th kit is th ebay one i presume, is that a riser i see on th bench, bought or home made, i'm after some about that size.

    backtracking a bit. How wide are your bars and did you get them to stop hitting the tank with your risers?

    2nd, did you just sand blast your whole motor?

    TIA and it looks great!

    Gave up on the drag bars to get licensed and never went back.

    Motor was only degreased. The 820 big bore motor I'm about to start assembling is going to be vapor blasted if budget permits.

    We now have new manifolds.

    [​IMG]

    I managed to achieve 1.5mm internal taper so it matched both the throttle bodies and the intake ports much better then the original factory manifolds.

    [​IMG]

    I like the look. :D

    [​IMG]

    You are looking at way over 20 odd hours of work (I have lost track), a real machinist with all the right gear and knowledge would have done it in a fraction of the time :oops:

    [​IMG]

    Throttle bodies can now be connected with 2" silicone hose and clamps.

    [​IMG]

    Perfect alignment of centres. Measure 20 times, cut once.

    [​IMG]

    Very happy with the outcome of many hours.

    Stay tuned for more soon.

Good for him he has all that time I would love to have my kids grown up to have all that time and be able to accomplish projects like that but I am way to busy raising kids and take care of wife which in my case is a hands full.

    BTW if thats an insult I am sorry.
    Where I came from the only way to insult someone is saying something about his mother.

    Time on my hands? This project has been going on for over 2 years, and the EFI system for close to 12 months. I spend less time on the bike than most people spend watching television (which I don't).
    As for the fuel pump, I intend to get a unit from a Honda Rincon (same as Gennro has). According to the Microsquirt forums it only draws about 2.5 amps, and comes complete with a swirl pot assembly. The tank will feed the swirl pot via the original lines.
