Bit of an update to keep you all well!! updated.
Beanie loves this bike. The thought of parting with it fills him with horror.
The bike has done 91k miles which is pretty good. It is in remarkably good order for the mileage, however things do and have worn out on it[Beanie not included]. Some of the wiring is corroded but not beyond repair. Bearings have dried out but are salvagable so far. The engine was low on compression [not suprising really] and it burns lots of oil hence the state of the plug. A compression check showed it to be about a third down on normal. Drop of oil in the bores pushed this back up to a good reading. This would show the valves and top end is in working order but the bores are worn.
couple of options spring to mind.
1 Oversize rings. Personally I dont like this option as to get them to fit you need to file the ring gap to get it into the bore. Rings are round and by closing the gap you make them oval so not a good idea.
2. Rebore and oversize pistons. Downside is cost. Bike has done 91k so new bores and pistons should be good for many miles but the crank and all the other oily bits have still done 91k.
3.New rings and the barrels honed out prior to fitment. Replace valve stem seals regrind the valves and reshim. [This is the one I would favour] It should use less oil after the rings bed in but it will still use some.
On top of this you need to add the costs of gaskets which is at least £100.
Both tyres are shagged. Chain and sprockets are maybe/maybe not. But have not been fully scrutinised yet neither has the rear end been touched as yet so may well be some bearings in the swingarm etc to attend to..
Ultimatly the cost and what gets done is down to Cam. But you could buy a half decent TDM for £1500.
Needs a bit of though and a long discussion with Pippa.

As for the blocks of wood?? I have the bike hooked up to the roof of my workshop on a set of pulley's so the engine is about waist high. Makes access easy. The blocks of wood are under the swingarm to stop it swaying side to side. The flat bit in the middle of the tyre helps mind.
