bought this off ebay ages ago and was told it came off a k3 and bought from ds ( fibre glass base )
went to dry fit this today and its miles off, will post up some pics later, no way this came off a k3
still have original pan so may attempt to fix that, can you still get foams and original covers for them?
would like to hear peoples stories on fitting replica seats
thanks
-
some pics,
does the replica ds have different mounting points for the catch that goes into seat lock ?

That is indeed way off by the look of it, fraid I remember stuff all about the seat fit, one of my k3's had the right seat, but it was rotten, I rivetted a bit of alloy to what was left and it was very comfortable (rode around Scotland by scenic routes and back, taking a week, did the return trip in a day, felt fresh as a fresh thing when I got home) and it just about looked ok. The other bike had n seat so I bought a genuine old base off a US inport from California Connection in Derbyshire, the foam and cover were almost totally trashed, but I built up the eroded foam with an inch of foam out of an old caravan matress cut to shape with a breadknife and made a used a pvc cover off M&P but it was a bit lame, I've made lots since that were just as good or better out of black pvc from the fabric shop which costs about £2 per seat, rather than £20 and that was a decade ago. I've never got near a pattern seat and probably not going to need to given how many spares I have.
I wonder if you could move the hinges and / or seat lock to make it fit?
-
not only that the base comes into contact with the inner guard as well
not sure on moving seat lock as it does not look like any of the mounting points for the seat catch would line up with catch on the bike
all in all a disaster for me
-
Yeah, I see what you mean, leaves you with a seatbase where the most you can say about it is what it doesn't fit. I hava a suzuki one like that in the loft, that came with my 550k3, might be off a suzuki gt180 tripple or somit that the seller also had for sale in the same shed, who knows, mind you it is a better fit on a k3 than what you have. If your lucky then some carefull surgery with a kitchen knife might make the pattern foam fit the proper seat base. I don't suppose you can send the pattern seat back for a refund? Probably too long ago. I've over the years had to chop about a few seat foams to fit the wrong seatbut I'm only ever intersted in a comfy perch, never a restored / authentic finish, though a tidy job is nice.

the seat base is the original base off the k3 , it had a large chunk cut out of the foam and it and was rotten as was the seat cover
so I guess either foam it and buy a cover or look for another original seat :-\
-
A few years back I got a 750 replica seat from DS.Looked the bizz until you opened it crashed on top of the oil tank cap.Crap I thought sold it and rebuilt the original base blasted resprayed and new cover with chrome trim bloody good.

I am thinking about going down the fixing of original but how do I sort out the foam ? I have no original foam to go by
is it that important to correct shape of the foam ?
-
Mike,
Luckily for me the foam was in good condition so no problem there but because I have the 750 I have seen foams for it on eBay USA I am sorry to say tax etc.
Maybe chance your luck over there they do seem to have everything annoyingly.
Cheers

Bob the seat does foam for the K3, if you ask him nicely. But does cost.
-

Cheers

Bob the seat is Morretti. If you key in bobtheseat on ebay it will come up with his shop but, it will not show seat foam. So best email him at morrettidirect.
I did a seat for my F. Seat pan from the states £82. Foam £56. Cover £10.50 bid.
-
Mike, the seat you are trying to fit is not K3. Looks more like a CB350F.
-
yeah I bought it as a 550k3, once I have for definite what it is I will sell it

It is surprising how well a rotten base can be patched, hammer out smallish patches to fix the worst bits, if nessisarry, tempoarily rivett in place or g cramps and then brase weld into place, that and hours of wire brush in a drill cleaning, then paint with generous ammounts of paint. Foams need not be perfect I'd think as the cover tends to give the shape and smooth things over. Obviously getting it exactly right will take more time / attempts to get just right (but if accurate enough joins or repiars in foam vanish once covered). Or just hang in there and wait for a k3 seat to pop up out of the woodwork. There may be 2 in my loft, but as 1 is a known mess and the other is not known whether it was a 500, 550f or k3 and they are mixed with several cb500 seats I am not in a hurry to dig one out - the remaining cb550k3 is in bits too so trial fitting isn't possible. I'd be trying to fix your original, it looks better than the last one I did - not even sure that was a honda, might have been for my mates yamaha xs250.
