After that diversion into navigation programs, back to the shed stuff...
Two new tyres on my eldest son's 2012 Suzuki 250, that was still on the (badly cracked) originals... It has only done 11k Kms, and none in the last two years because the tyres weren't safe.
The Silverwing engine is on the bench, and I am currently making a special tool to remove the clutch, as it is sticking very badly. If it is anything like the clutch on the Goldwing, it will need to be stripped, the plates cleaned and re-oiled, then re-assembled.
Of course, I am also being interupted by life, so I am making haste slowly.
