    Head and barrel look like M49 or M80 250cc But could be VERY early 325cc Frame looks like late Miller (modified). Regards Sparks

    The Bultaco is a 1971 M80, Registered on 07.10.1971 as JWP 25K.

    The frame number begins M80.

    The engine number begins M80.

    Absolutely everything about it corresponds to it being as of that date.

    Why do you think it's a 1973?

    What maybe confused you, was that I said I thought that the tank could have been used on a later frame (because of the notches) but t...

    John

    You asked me to PM you on the matter.

    I should just add at this point, we crossed swords or had a discussion over Nigel Greenwood's Dalesman a little while ago.

    If you are interested I can add some details and background to the Bulto.

    The bike was registered JWP 25K in October 1971.

    It came to me in amazingly clean and original condition in March 1989. But, s...

    Thanks 2Fargone. Yes, but the Bultaco was registered in October 1971, too late for the 70 and 71 SSDTs So Karl would have been riding earlier Sherpas. But the bike could have been possibly ridden in subsequent SSDTs say 73 or 74 hence I asked for the seal colours. Anyway, thanks for looking up your results, great info, almost confirms what I thought. Regards sparks

    Hi On re-building my 1971 Bultaco M80 slimline I'm re-discovering some dabs of grey paint that I take to be seals from the Scottish. I'm assuming that this bike was ridden in the 1972 Scottish by Karl Rowbotham from Kidderminster. Can anyone confirm (or otherwise) that:- 1) Grey seals were used in 1972. 2) If not, a year when grey seals were used. 3) Karl Rowbotham rode a 244cc Bultaco in the 1972 SSDT and his number. 4) Any pics would be more than fabulous. Thanks in anticipation. Kind Regards Sparks

    Hi Yes, I will have to say early sixties Cotton trials frame. (Wrong (slighty) again). Regards sparks

    Hi (again) No, I have just checked, the starmaker trials frame was single downtube and different in the midriff area. The frame looks much more like the Cotton 'Cobra' Starmaker or Villiers 9E type engined scrambler which was twin down tube. But, as they say, I could be wrong. Regards Sparks

    Hi That's interesting, never thought of the cotton starmaker trials. The 1966 'D' reg plate would be absolutely right for that as would the forks and hubs. The MP forks were an optional extra from Cotton at the time. A real rarity. Regards Sparks
  11. sparks2
    Hi My best guess would be Cotton or Sprite Scrambles (Motocross) ie not trials The forks are MP. Regards sparks

    Wouldn't ten and a half have been pretty standard regulation Bultaco and Montesa wise in the early seventies? The Dalesman had about thirteen but that felt top heavy.

    woodruff key sizes

    sparks2 replied to myson's topic in Bultaco

    Hi Yes, I concur with nb - Hugh's Bultaco. Don't forget there are 3 sizes of key - magneto, crankshaft and gearbox mainshaft. Regards Sparks

    woodruff key sizes

    sparks2 replied to myson's topic in Bultaco

    Hi Have just replaced the crankshaft and mainshaft keys on my M80. Be careful because the proper Bultaco type are hardened and are chamfered to fit the key slot in the shafts. You may get away with a mild steel key for the magneto which has a taper drive but definately not the drive side (IMO). I had to get the mainshaft drive key from USA. Hope this helps. Kind Regards Sparks2

    Hi I know of no-one today producing that type of silencer. The type was fitted to the late works and the Comerford cubs. I believe the type originated with the goodies made for the cub in the mid sixties and marketed by Comerfords, Sandifords and others. I think Alan Jefferies supplied this or something very similar up to the mid to late 1980's. Would be interested if anyone could come up with a supplier or further info. Regards Sparks2

    Hi Has anyone got a RAL number match (or any colour match) for the Bultaco red on the M49 or M80 fibreglass. Thanks in anticipation. Regards Sparks2

    Hi By 'knocking and chattering' do you mean the engine is pre-igniting? If so check the exhaust is internally clean and unobstructed. What happens when the exhaust is not clear and the engine is warm, the hot exhaust gases do not clear the cylinder sufficiently and the incoming charge is pre-maturely ignited. I suspect that the 340cc M199b is particularly prone to the problem as it uses the same exhaust as the 250cc M198b. I may be barking up the completely wrong tree of course, but worth a thought I think. Regards Sparks

    Thanks MM I will print the info off and digest when I have the odd 2 hours to spare. And I always thought it was the MM of motion picture Fame. Ah well. Thanks again. Regards Sparks2

    Hi there Can anyone help please. On TC I have seen a natty little item I can only describe as an in (fuel) line coupler / de-coupler. An item that 'splits' a fuel line with a twist or bayonnet action. At the time I put the link into favourites, but since have had computer troubles and have lost favourites. Thanks in advance. Regards Sparks2
