    I have not been able to work on the bike this last month what with work and weather. The rain has been very heavy and long lasting here in the UK 'but the project will be carried on with as soon as conditions allow. I hoped to do some work on it yesterday but I was called into work on an urgent basis
    Still enjoying the site though

    Don't get me wrong, EFI is wonderful idea, but if the underlying problem is that CB250RS carbs are overpriced and unavailable, the XL250 had a very similar engine, and the CB750A 750 Hondamatic used four Kheilin PD70 units side-by side (by side, by side) and it might be a lot less grief chasing down one of those units - only saying!

    Take a look at the speeduino project, opensource system run on an EFI analytics (megasquirt) based coms code. Very cheap unit for the capability, and an awful lot of forum support. Looking at buying one for my zxr as soon as the bike budget allows!

    I've been looking into the Rusefi system basically because of the up front cost of the ECU is minimal and the project has 7 years worth of momentum and numerous successes

    For your throttle body and injector there's probably load available from current lineup which would be suitable

    The little Honda was taken for a MOT today I am pleased to say she passed
    Having said that the front caliper needs a bit of of tarting up
    I have been looking for a replacement Does any one out their that they will sell to me here in the Uk
    I just need to do a little tarting up on her I did change the handle bar to a flatter style That I now realise was a mistake and I will be putting the original back on
    Nice revy motor that goes well I will fit the new sensor and meter it bin in its box for two years
