    Cam Timing Way Off

    I remember having to set the points up to fire separately. Now I'm running the Pamco setup. The bikes running now so I reckon I did something right.:thumbsup: Thanks again.

    Cam Timing Way Off

    That makes sense, thanks for clearing that up.

    Cam Timing Way Off

    The lobe positions sound right from memory. Does a 650 fire every time the pistons hit TDC? I thought a four stroke meant that the first time the pistons rise, the fuel/air mixture is compressed and ignited and the next time they rise is when the exhaust gases are being pushed out. Does this...

    Cam Timing Way Off

    Is it possible to set your cam up 180° out? What I did was I sighted my left piston to be at the top of the stroke. Lined up the cam notch vertically and made sure the dot on the cam was set as per the manual. Is this correct?

    vm34 cable setup

    I'm no expert but the idle is set up on the Carbie using the idle adjustment screws, the cable is used to open the slides. The bike should idle OK without any throttle. The throttle is adjusted at the throttle end. Do you have a manual for the Carbies? If your bike won't idle, I'd check other...

    Not enough Exhaust valve adjustment

    mmm, how many teeth are there on the 256 cam as opposed to the 447? I am also wondering if I set the cam chain one tooth out? could account for the lack of adjustment because even the inlet valve doesn't have that much adjustment room. I thought I did it as per the manual though. The collett...

    Not enough Exhaust valve adjustment

    Thanks, the seat didn't look like it had been ground before but the engines history is unknown. I agree with you about the sticking valve. I did put a donor cam in; does anybody know if there was a difference in the cams between models or engine types. I have the 447 motor. I'm going to take the...

    Not enough Exhaust valve adjustment

    Hi all I've been adjusting my valve clearances and come across an exhaust valve that won't open enough to get a .15mm feeler guage in. Does anybody know what could be wrong? Sticking valve maybe? The valve appears to go in and out OK, new timing chain adjusted OK. Other valves adjusting OK. I...

    Engine Rebuild questions

    If I had the head off, I'd do as much as I could afford to it while it was off. It doesn't cost much to give it a valve grind , replace the valve stem seals etc.

    Seat compatability between models

    Thanks 650 skull. First person I've come accross that has the same model as me. Mine is 3W6 as well, and getting the right parts is a bitch. You order a part for an SG and find it's not quite right. I'm gonna have a go at re-upholstering a seat pan I've just sourced in the US. Could be...

    Seat compatability between models

    I've got a 80 special, Oceana model (Australian) which is wired up and set up much as the 79 was I think. Points ignition, twin discs on front and mags etc. Thanks for your input too. I'll work on a link to the ebay seats, haven't done it before. thanks

    Seat compatability between models

    Has anybody bought one of those seats from Vietnam made for the XS650? They're advertised on Ebay. What was the quality like? Are the pans set up properly for the standard hardware as they advertise?

    Seat compatability between models

    Can anybody tell me when the XS started on the rear hinge for the seat. I'm not that impressed with the special seat and would like to fit the flatter seat of the older models onto my special. Has anybody put a new seat (cover / padding etc.) on the special base that looks like the older seat...

    Engine misses and loses power above 3-4000 rpm

    Engine misses and loses power above 3-4000 rpm

    Thanks guys My timing chain is new and adjusted OK. It was tight to fit on , so I reckon it was the correct size. The voltage is as follows; 1. 12.7 volts 2. 10.9 3.10.9, the draw would be from the headlight I reckon. For some reason, the strobe doesn't work on the other side even though i have...

    Engine misses and loses power above 3-4000 rpm

    Hi Pete I checked the advance mechanism and it appears to be working as it should. When i checked the timing, I can get pretty close to it but there is not quite enough adjustment. Also, when I increase the throttle the timing mark moves towards the advance and when it gets to a certain RPM the...
