    I've bench balanced then dynamic balanced the carbs. I have no idea why the carbs are being so much trouble. I'm so good at pulling these motors in and out now I can do it in about 30 minutes flat if that. I've flushed and blown the carbs out a few times now, I even had some leaks so cut my own gaskets carefully and got the floats to stop pissing out the overflow.

    But I get on it and its flat, also oil leaks to africa cause the seals are hardened in the cam covers and oil filter spin on housing thing. The plugs are new and my next task will be to change the coils for newer ones, insulate and make sure the leads are working fine, blow all the oil and crap away from the sparkplug boot area after fixing the oil leaks and hopefully have the carbs soaking in some wicked evil cleaner while I do all this. The compression on the new motor is 230psi both banks, it starts easy. I dislike having a bike that is this much work though.

    Also my gearshift is backwards on the new motor, up is down a gear, down is up a gear. I've completely no idea how that even happens.

    The new motor is from a later model. They run a linkage from the gear lever to the selector shaft. I'm assuming your old one had the lever straight on the shaft. Simple.

    This seems like an overly elaborate way to make me fabricate something that shouldn't exist. Apparently the MC08 had these. I'll have to make a new linkage and pivot now to -_-

    Just ride it race pattern. You'll get used to it quicker than you'd think.

    Some of my bikes are normal shift, some aren't. You'll stop thinking about it in no time.

    People actually run the shifter backwards?......

    Learned something today at least lol. Maybe I should put the carbs on backwards, probably work better than it does now.

    Yip, most racers do it for faster upshifting on the fly. Some people can't wrap there head around swapping back and fourth, so they just change all their bikes to one or the other.

    Hahahahahaha, have you got an airbox on the carbs? CV carbs will have a fit without one.

    No box but I'm probably leaving it off until it stops playing up or I'm just removing every 5 seconds. One cylinder is dying at the slightest throttle, without the box it runs shit up top but at least you can twist it open and get a response, this is just dropping a cylinder completely every time. I'll have to figure out which cylinder this weekend and just work on that carb for a start.

    I was going to try look at it tonight but the GN snapped a clutch cable then decided to have some kinda fit after I put gas in it. I think there is water or something in the fuel I bought. Was backfiring like crazy. The whole breaking everything at once thing is getting old.

    The box doesn't make a difference, cept to make me spend an extra 3 minutes swearing at it trying to remove it. The SLIGHTEST throttle touch is making one cylinder go haywire. It's nothing to do with the box, I had the box on and it's the same shit all over. I don't want the aggravation of that chunky POS being in my way everytime I try to do something.

    Say box some more!!

    My Spada was a cunt of a thing without a box on it, and even jetted to suit, it lost power. But that's okay because box is good and I loves box.
    Box.

    Not saying it's your issue. Just want to keep typing box. Because I'm a grown up
