triple_x Posted March 31, 2009 Report Share Posted March 31, 2009 (edited) Hi everyone. Need some advice please. I am rebuilding my bike to original, it needs a lot of work. Before I strip it down i need to run the engine and check the gearbox functions. However I am stuck for a rear break plate. The problem is that mine has the (I think) Pursang rear hub, two piece hub held together with M6 Allen screws. Tried Bultaco uk but they cannot help. Any suggestions would be appreciated. Thank you in advance. Martin Edited March 31, 2009 by Triple_X Quote Link to comment Share on other sites More sharing options...
swooshdave Posted March 31, 2009 Report Share Posted March 31, 2009 So are you looking for the rear brake plate, the correct rear hub or to see if the gearbox works right? Quote Link to comment Share on other sites More sharing options...
triple_x Posted April 1, 2009 Author Report Share Posted April 1, 2009 Thank you for replying. Basically I want to get the bike together and running before I decide how much I want to spend. To give you an idea. Front hub needs sleeving Lower tubes under the engine need work, Rear hub needs re chroming Mikuni carb does not look like the normal in fact it may be off a road bike. Now, I realise that I could get a complete wheel assembly for another Sherpa but it would be nice to keep it original.

swooshdave Posted April 1, 2009 Report Share Posted April 1, 2009 What condition is the bike in now? Boxes? Partially complete? Can you post a picture? With some bikes it's better to get them complete and running and then tear them down. That way you know what's missing or needs replaced. I almost think the Bultacos are so simple that you can get away with building them up just using a parts manual. Of course it helps if you have rebuilt a couple before.

triple_x Posted April 1, 2009 Author Report Share Posted April 1, 2009 Hi The bike is complete but has not been looked after. The frame has been really trashed around the primary cases but it is straight it just needs a complete going overgoing over. I know where to get the work done but my mistake was not researching the brand and not picking up on the fact that the rear brake plate was not original. My plan is to get the engine running and check for strange noises if none then strip down sandblast and powder coat the frame and gradually put it back to standard. So far I have fitted a new Kick start spring, Air filter and am shortly to fit points and condenser. I have worked on numerous Trials bikes in the past so this was seen as nostalgia trip ending up with a working toy in the garage to keep my Street Triple company. Back in the sixties I had a 197 Scottish, 24 tes Greeves, a new 1966 Anglian, the first Montesa Cota out of Westbury motorcycles in 1968 and finally a 1970 Greeves Pathfinder followed by the ex Paul Dunkley Cheetah. But I never had a Sherpa. If you are interested I can email photo but i do not know how to post them on the forum.

triple_x Posted April 1, 2009 Author Report Share Posted April 1, 2009 H Worked out how to post photo. Martin Quote Link to comment Share on other sites More sharing options...
swooshdave Posted April 1, 2009 Report Share Posted April 1, 2009 And the goal is to restore back to new but leave the engine alone, if it can be helped? If it were me I'd just restore the chassis and parts and put it all back together. If the engine or tranny end up being a problem you can easily pull the engine and tending to any issues. While the bike is apart you can source any missing pieces. Just my .02 Quote Link to comment Share on other sites More sharing options...
woody Posted April 2, 2009 Report Share Posted April 2, 2009 Your best source for a brake plate is the USA. A lot of Bultaco parts including brake plates regularly appear on ebay US. Or try the various specialists like Hogans, Hugh's etc. That hub was only fitted to the 124/5 and maybe 150/151 Sherpas so the chances of finding a used one are slim in the UK and Pursang parts rarely come up either.

triple_x Posted April 6, 2009 Author Report Share Posted April 6, 2009 Thank you all for the advice re the back plate, no joy so far but will keep looking. Are there any other alternatives that would get me mobile, say more a popular hub that I could get built up? Other news, sorted out the wiring from the low tension coil, fitted new points and it fired up second kick! There is plenty of compresion but it is a bit clanky on tickover, but at least I know it is a runner. Kind regards Martin Quote Link to comment Share on other sites More sharing options...
woody Posted April 6, 2009 Report Share Posted April 6, 2009 You could fit a later rear wheel as fitted to the 1976 model 159 onwards. Or a Grimeca style rear wheel as fitted to Fantic, Armstrong etc will go in I would think. I've seen one fitted to a 340 Sherpa. Quote Link to comment Share on other sites More sharing options...
andy m Posted April 6, 2009 Report Share Posted April 6, 2009 I use a site called fat fingers to trawl for badly spelt items on ebay. There is some one in the US spelling Bultaco with 2 l's and they have Pursang bits listed. May be able to help ?? http://cgi.ebay.com/ebaymotors/1974-BULLTA...sQ5fAccessories Quote Link to comment Share on other sites More sharing options...
