    Yes thank you... "Triumph2" informed me last week. It fits perfectly. Somehow I have a spare one too!

    Does anyone have a Manxman with stock mufflers? I am tryig to hang my mufflers (NOS original manxman muffler) and they seem to rub the axle nut unless i use an spacer between the muffler and the frame. I know there is not supposed to be a spacer there. Any pics of a mounted exhaust system would help. Here are some pix of my progress so far...

    I am curious about one thing...
    I see the rear shocks do not appear to be original. The result I see is, the rear swing arm hangs down farther than on the manxman I have here in the shop. If the axle was held higher( by a shorter shock) , the axle would not hit anything. :?:

    ok, those are the shocks that came on the bike. Could you send me a picture of proper shocks? That may solve my problem!

    Shocks came with the bike?

    11-1/4" C-C of the mount bolts
    Swing arm is only VERY little below parallel with the top of the foot peg/muffler mount arm. Yours appears to have a LOT more droop.
    Spring covers are longer than yours and are painted blue.

    I have the blue covers, just never changed them. These were what came on the project. These shocks are 13", way too long. I will order the right ones. That should solve my clearance problems

    Ok, I swapped out the shocks. Now the exhaust and pegs fit correctly. Assembly and rebuild almost done. Next is to get it running.
    Another question: The gas tank mounts in front with rubber bumpers and bolts. the back end of the tank has a hook that appears to grab under the seat. Is that the only thing that keeps the the back of the tank down, or is there another mounting bracket that I am missing?

    The rear of the tank is held down by a rubber strap/loop, although you will need a "tank rubber" fitted to each frame rail toward the rear of the tank (see below)

    Most shops sell these

    I have those rubbers, but what does the strap/loop look like? You mean the big o-ring/rubber band thingy? How would I properly loop it on? I can just wing it... easier to use a zip -tie

    My frame had two steel "spikes" (about 1/4" diameter and 1 - 2" long), welded (pointing rearward) to the frame cross-member under the rear of the tank, that the seat spigotted onto.
    And yes - the oversized o-ring (I doubled mine) stretched from the hook on the tank then over these spikes
    Let me know if you need a photo
    Cheers

    Got it. No need for pic. Thanks. It's amazing how much is missing from the parts diagrams.

    Another question: rear fender has a hole in it just behind the seat. There is a wire welded on the underside of the fender visible through this hole. What goes in that hole?

    There is a special "screw", I believe called a dzus (1/4 turn - engages on the wire), which holds the rear seat bracket (triangular) unto the fender (called mudguard over here)
    If you Google Image dzus you'll see what i mean
    Cheers

    Ok I checked my seat, It has the metal tab broken off. But even if it was there it would have to be pretty long to reach down the fender down enough to fit in the hole. Could the stock red manxman seat be shorter than the standard 650ss seat. Or,...The fender may be from an atlas and was not original to this build. Perhaps the seat mount hole is different for different models. I am in the process of getting the original fender rechromed, so perhaps a better fit. But i still am tab-less on the seat. Anyways, just another tweak to fix on a 50 year old bike.

    Hello The Manxman silencers you cannot buy anymore on one has ever made any aftermarket ones,,, now the right-hand side silencer is bolted on with the passenger foot rest and has no spacer on that side but the left-hand side is the same but has a 1-inch spacer to keep the silencer off the brake back plate hope this helps and not shown in the drawings has this drawing is for a dominator, not a Manxman which does not have any drawings but they do have their own part manual

    Hello No the rubber ring does not FIT over the two seat hooks it fit on its own bobbing on a bracket looking downward in the centre of frame at the rear just before the seat hooks the rubber ring is adequate has it takes some getting on right and can be fiddly

    I am with annajeannette reply on this one.
    As to the tab being broken off, can I offer a suggestion?
    Cut some old inner tube and use it over the two seat hooks.

    A few bikes with the short tank used a seat with rearward moved positioning mounts, thought both seat pans were the same. This moved the seat position forward to close the gap.

    Manxman used an early fender accommodating the early taillight. The later 63 atlas fenders will not accommodate the early tail light without drilling holes and leaving excess holes visible.
    Either fender... "Dzus seat tab hole" will be 10-1/2" or 8-1/4" forward from the line drawn between the fender mount bolt holes. 10-1/2" regular seat/tank or 8-1/4" for small tank/forward seat.
    On my 63 bitza I will have to extend the seat tab 2" to use the short tank. Along with moving the rest of the seat brackets.

    The Manxman seat and the seat for the early Atlas with the similar small tank was longer than the seat for the normal tank/slimline bike. The base of the seat extends beyond the half rounds pressed into the seat for the rubber inserts that the two rearward facing prongs on the frame fit into. If you look at the advertisements and the Cycle World review for the Manxman it's obvious that the seat is extended to fill the gap that would exist if the other seat was used. BTW very cool very original looking Manxman in the picture.
