Signed off for a couple of days with sinusitis so more antibiotics and another weekend off riding… so thinking I’ll take this weekend to do the rainy day jobs on the trials bike. Main job is the crank seals plus got a new pair of piston rings to fit plus  I’ll repack the silencer, grease everything whilst it’s apart, etc… anything to beware of when splitting the cases on these? 
 

Every other part of working on them is quirky so expecting something, don’t think there’s any consumable parts I’ve missed like lock tabs on the clutch basket or anything like that… just steady away and take lots of pics whilst disassembling… feedback welcome. Cheers. 

If you have a good search of the net, Jim Snells films of stripping and rebuilding the engine are still around. well worth looking at as they are a bit different to most engines.

Good point, his videos are spot on. 🍻
