majesty320 Posted July 24, 2006 Report Share Posted July 24, 2006 (edited) Though Id post a couple of pics of my newly restored m80 sherpa. I know its not competitive in the twin shock class, but I think it was one of the best looking trials bikes ever built, and besides that trickest bike in the world wouldnt win with me on board. Hope you like it. Cheers Mark p.s anybody out there got a triangular silencer for this bike. Edited July 24, 2006 by majesty320 Quote Link to comment Share on other sites More sharing options...
mickmetcalfe Posted July 25, 2006 Report Share Posted July 25, 2006 Try Sammy Miller's (01425 616446?)- he shows one in his catalogue. Not cheap but its a perfect replica Quote Link to comment Share on other sites More sharing options...
sherpatensing Posted July 25, 2006 Report Share Posted July 25, 2006 Bike looks great. Pictures of my restored 159 and 199B are somewhere in the forum. It may not be the most competitve twinshock to ride, but, as you say, it is visually. Regarding the silencer, be careful of the quality of the Miller ones.

woody Posted July 25, 2006 Report Share Posted July 25, 2006 Very nice indeed, lovely job. These bikes are just crying out for a Pre74 or 75 class in the ACU Classic series. They don't stand a chance against the more modern stuff with good riders on board but it would be great to see them able to compete in a class of their own on an easier route. Enough are being sold on ebay, as are Ossas and Mont 247. Quote Link to comment Share on other sites More sharing options...
twinnshock Posted July 26, 2006 Report Share Posted July 26, 2006 Be carefull when buying a modern replica silencer. Some have been produced that are externally excellent but are nothing but an empty box inside. I have an original triangular silencer on my own model 80. It has a huge effect on the exhaust noise making the bike sound quite but flat. Only issue is that it is very close to the rear of my boot and gets bent backwards and inwards and then get's knocked by the swinging arm. I have to readjust it's position on a regular basis. Any body else experianced this problem? Stuart Quote Link to comment Share on other sites More sharing options...
majesty320 Posted July 26, 2006 Author Report Share Posted July 26, 2006 (edited) I intend to ride it at our local pre 65 clubs twin shock class, I though about fitting the original style metal mud gaurds but desided agaist it as I didnt want them getting damaged. If I fit a silencer how badly is the power effected, as its really loud, on par with a motox bike. Im probably only going to ride it until my Majesty is back up and running, this is being converted back to a 250, so if theres anybody out there who wants all the necessary bits to build a 320 let me know. 320 barrel newly rebored head with one broken fin 320 piston used once crank cases machined to take 320 piston head gasket opened out to take larger piston spacer for between barrel and crank cases read block spacer Flywheel with full width weight ( exchange if possible for 250 item) Let me know if your interested, serious offers please as I know how much this stuff can change hands for, Im only selling it as the 320 is to powerful for me Edited August 1, 2006 by majesty320 Quote Link to comment Share on other sites More sharing options...
rcgods Posted July 26, 2006 Report Share Posted July 26, 2006 You hity the nail on the head... the exhaust note is quieter but the power is restricted with the triangular box, also it fouls your leg. Why do you think riders took them off in 1971? Big John Mine was taken off one bike for the reason and the other was destroyed in a fire . Put it onto my (running) restoration project bike (laid up since 1985) and tried to start it, took the box off et voila! A runner was mine due to taking the horrible box off.

bultaco49 Posted February 16, 2007 Report Share Posted February 16, 2007 Another source for the triangular silencer (and other Bultaco parts) is at http://romeromotos.com/ingles/principaleng.htm. It's a Spanish site but you can send and order in English. There is an online catalogue with photos. Quote Link to comment Share on other sites More sharing options...
