    this is why im confused with what electricals to buy
    heres 1 aprilia sr125 regulator
    http://cgi.ebay.co.uk/APRILIA-SR-12...em&pt=UK_Motorcycle_Parts&hash=item2eabd90560
    heres the another sr125 regulator
    http://cgi.ebay.co.uk/APRILIA-SR125...em&pt=UK_Motorcycle_Parts&hash=item335dfb4e41
    heres a gilera runner regulator
    http://cgi.ebay.co.uk/GILERA-RUNNER...em&pt=UK_Motorcycle_Parts&hash=item3a59a2910c
    now many says theyre the same but the first link has the most common rectifier.....looks totally different than the runner......would that work with the runner 125 stator and flywheel??? the answer to this would help me a ton..... :cheers:

    the rec is fuck all to do wiht the engine prittymuch, its usually dependant on the rest of the wiring, wich on aprilias, is shit, pritty similar to the rest of them then. dont use a runner rec. use a rec that matches the loom your using or if your nocking somthing up then dont run a rec. can wire a killswitch wihtout one and cut off the charge coils in the stator. if your running a loom then ether use the 50 loom wiht an apropriate rectifier or run whatever rec off the loom your going to adapt to your bike. sorted.

    Hi, Sorry to be going off topic a little.
    But what's the procedure for a 55mm crank? Do I need to drop the ports 3mm? and I think the 55mm crank comes with a 1.5 packer plate? Or am I going in the wrong direction here?
    Or if you have any port maps of just barrel correction for a 55mm crank you could throw up on here? Would be greatly appreciated. Thanks, Conor.

    if youre talkin bout the manifold its a stage6 with spacer....i have two options...grind a small corner in the case so that it sits flush or machine the stage6 spacer....most likely im going to machine the manifold spacer haha......looks great though...too bad it doesnt fit out of the box

    This is currently where I'm at... I'm basically mocking up the motor to the frame... I was wondering which spark plug you pros recommend?

    Hi everyone... Changing to rear disc.... How do I take off that stud that holds the brake drum in place? I know one of them is for the lever but the other ones a straight stud.... I may go bakbyo drum one day so I don't wanna cut it

    with your TDR i would run an 8 rather than a 9 if your just going to screw it in there then a br8es is plenty good enough but if you fancy spacing the plug as your engines apart then go for a BR8E-IX well worth the extra effort for a small gain .
    i would not cut the case to use the stage six mount theres far better manifolds that dont look as trick but work so much better straight and short is not always better the one i use is 11 quid from ve .
    when you fire that engine up for the first time savour the sound of the TDR at full throttle it will give you a boner :blush:
