Spend some time just looking at and studying pictures/videos of Bultacos and the detail. Take photos of what you have for reference later or when sourcing parts. If you have to split the engine be aware that although gearbox and clutch internals may look the same, there are subtle differences between some models and later parts may not interchange with your crank cases in the case of gearbox, or mainshaft in the case of clutch hub and basket
#BULTACO PURSANG AIRBOX MODS#
A later hub from the next model onwards will fit with no mods other than a different length spacer might be needed (if you meant a brake plate rather than brake hub, a Pursang brake plate may fit as your model Sherpa hub was based on a Pursang one)Īs the previous poster said, Hugh's Bultaco should give you all the info you need. The rear hub was unique to your model and the one before it (124/125) and would be hard to find. Later pedals will fit if you're not bothered about original look. Brake pedal new or used, if used it needs to be from a model from '68 up to your model. One from a same year Alpina should also fit. The outlet to the carb needs to exit from the bottom left of the airbox, so that it clears the sidepanel of the tank/seat unit, not from top right. Airboxes come up fairly often on ebay and the same one was used on the 71 onwards Sherpa to your model, also similar year Alpinas. Tank/seat unit may prove difficult, not sure if anyone in the States reproduces them, used come up on ebay but may need repair and sealing against ethanol fuel. You need one from a bike with the same side casing as yours which was fitted to all Sherpas from your model onwards, as earlier models have a wider bend for the different shaped clutch casing.
Gear change lever can be had new although used come up on ebay.
Can be replaced with a 26mm Amal/Mikuni/OKO - Mid Atlantic trials have decent deals on OKO carbs. The parts you mention should be easy to find, carb was 25mm Amal originally but not really worth risking an old used one.
