I finally finished preparing the frame and got it. Rubbed down ready for painting. I left it over with a friend and hopefully he'll get it done in the next week or two. I'm looking forward to starting to put her together again. It's been spread out all over the floor for too long. Wednesday, 5 November 2014. 32 - Work in Progress. Include...

I got a piece of 21mm AF stainless steel hex bar and made a couple of new nuts. One for the centre of the clutch and one for the front wheel spindle. One of the old ones had been tightened up with a hammer and chisel by the looks of it. I've got plenty of bar left so might make a few more if anyone needs one. Monday, 11 August 2014.

M80 Bultaco Sherpa Restoration: December 2014

Back when I stripped and rebuilt the forks one of them was sticking a bit at the bottom of its travel. If you pushed the stanchion up and down the fork leg it felt like it was binding a bit. A tug would release it but it didn't feel like the other side, which was sliding nicely. So I reassembled it again, put the rubber boot over the fork and left it aside.

Things have been slow over the winter. It is just too cold to feel like going out to do any work in the shed, but now I have the frame back and want to make some progress again. I've left in some parts for chrome and zinc plating, and the rear shoes for re-lining so I hope to get them back next week then get the wheels into the frame.

M80 Bultaco Sherpa Restoration. Blog about the restoration of a 1971 Bultaco Sherpa model 80 trials bike. Tuesday, 31 March 2015. 38 - finishing the brake. After a comment from Michael I thought I could remember there once was a big rubber seal which sat in the circular groove beside the brake shoes. I guess the idea was to make a seal to prevent water and dirt entering, but how well it worked was debatable. I would think that unless a lick of grease was kept on it, it would soon wear flat. I decided ins...

M80 Bultaco Sherpa Restoration. Blog about the restoration of a 1971 Bultaco Sherpa model 80 trials bike. Friday, 23 May 2014. 21 - Thoughts on bearing choice. On the rare occasion I changed the gearbox oil I noted that it was a little dirty. It was as if mucky water was getting in somehow. I was giving this some thought and looking at the drawings in the Bultaco books. All of the bearings I took out of this engine were of the plain open type and this I think is where the problem lies. For the crankshaft...

M80 Bultaco Sherpa Restoration. Blog about the restoration of a 1971 Bultaco Sherpa model 80 trials bike. Wednesday, 24 June 2015. 42 - Guard fitted. I finished the guard by fabricating a little stay and getting it welded on. I know the original was riveted but I opted for welding. 12 July 2015 at 08:31. The bike is looking great, everything is really well made and well thought out. The brake adjuster is a real beaut. Subscribe to: Post Comments (Atom). 41 - Chain guard cont. 42 - Guard fitted.

Today I spent a couple of hours outside with the frames. I ground and sanded away the old welding from around the sumpguard. It looked tidy but it revealed another crack. That's two cracks now. I also cut the head off the bolt that was holding the brake pedal on. It will be replaced with a proper pin. Sunday, 30 March 2014. 8 - The Swing Arm. So the swing arm d...

After forming the curve on the top of the guard I marked it out then cut and filed it to shape. It needed a dimple at the front to allow for the head of a screw, so I made a press tool from a couple of bits of scrap bar. It worked out pretty well. 12 July 2015 at 08:34. Very, very neat.
