I took the A7 for a run out into The Peak District yesterday, this photo on the back road out of Bakewell looking towards Baslow.
The bike is running well after sorting a catalogue of issues following the collapse of the dynamo drive idler sprocket apparently 'seizing' the engine.
After getting a van drive home I started by stripping the top end fully expecting to find a damaged bore etc. Eventually stripping the timing side revealed the damage which I cured by fitting a belt drive, cost £85.
But that lead to a bad oil leak caused by using an old tube of blue hylomar sealant, no good!
On stripping again to replace the offending seal I then discovered that the magneto pinion was suffering a huge amount of play at the bearing, so off it came and I had the bearings sorted by local firm Armoto (New Whittington, Chesterfield) Seems they've done a good job but it cost me £90
Then I discovered that the breather hole on the inner timing case was blocked (and always has been) with a very authentic looking cross head screw which I couldn't shift. This casing has been on the bike for many years so presumably I've never had a breathing crankcase?? So dragging a spare casing out of 'stock' the engine is now reassembled and all OK with very little oil showing at the breather.
And I think that the engine is running better than before, perhaps not a surprise ?
Anyway, it was a sunny day so all is well !
