    Considering EFI; What type of ignition system on 82 xs400rj?

    If it were me, I would try to score the ITB's off of a Liter bike. Just use 2 of them and already you have the injectors, Throttle position sensor, and most likeley they would be sized pretty closely to the induction requirements of our engines. You might even be able to retrofit the fuel pump...

    @Drewpy, Got it, I will try a self tapper tonight. I have some stinger scrws with some nice big threads that I think will work well for this. @BCware, I think a video like that would be awesome. I look forward to seeing it. @Jayel, Thanks for the link. That PDF clears up a bunch of other...

    So will that plug pop off with a pick tool, or is that something I am going to have to drill out? And with the adjustment on the float, do I bend the floats so that the tang with the "wire/spring" is in the same position and the rest of the float is higher, or bend the whole thing so that tang...

    Ok so I disassembled the crabs completely tonight and had a good look. A few things struck me as odd. First, I have no idle adjustment screw. It looks like it never had one. heres a picture of what I'm talking about, if I'm right, this is where they should be... Second, I read somewhere on...

    So heres another question, should there be a gasket between the boots and the cylinder head? I havent pulled the boots off yet, just the carbs, but Im wondering if i should put a thin bead of silicone or make a cork gasket where the boots bolt onto the cylinder head. I am trying to eliminate all...

    Just looked again. It looks like the pilot air jet is the 155, the pilot fuel jet is a 42.5, and the Main jet has no markings on it other than the letters JET PO. Is any of this making sense?

    So I pulled the carbs off today. Turns out I do have the ones with the Brass Floats. I noticed in another thread you had advised someone to bend the arm holding them so that the float sits at 26.4mm off the base of the carb. I am wondering if this is something I should do as well? I pulled out a...

    Thanks for the timely reply! I will be honest though, I was just guessing at the 750rpm figure. As soon as I am able to get the tach working I will report back with a more accurate number. On mikesxs.com it looks like all the jets are for a xs650, but I believe I read the the carbs are the...

    Are the front forks off a bike with Disc brakes? edit: I'm guessing they are since i see the wheels with discs on them. Any chance you have the M/C lying around?

    Hi everyone, My name is Zach, and my father and I just picked up our first project bike, an early XS400. Im not 100% sure what year/ model it is, as it seems it has some conflicting equipment on it. I know it is an early bike because it has wire wheels and drum brakes, but it also has electric...
