Good progress Alan. Baz will have it sorted. You should be on the road before the summer is out.

Hmmm. Hopefully that'll be THIS summer.
I can't do more than one without a 550. :roll:
Not that one anyway....... 8-)

I really take my hat off to you guys with multiple bikes :roll: I don't know how you manage to ride them let alone maintain them as well? I only have two and struggle to keep them both happy :lol:

Well, onwards and unfortunately downwards.
Definitely a 'Oh BUGGER' when I too the head off and looked down the right side pot.

Wonder whatever could have caused that?

Shouldn't there be summat else in there? Like a clip?

Looks like a scrounge in the spares boxes. I'm sure I have a good Nikasil piston and ringset, but the barrel's another matter.
Mebbe, just mebbe........ :roll:

Failing that, has anyone got a good Nikasil right cylinder they want rid of? :cry:

Baz may have one. When he did my engine rebuild he had a few spare nikasil barrels. I had a NOS RH barrel which Baz used on my engine, so he will more than likely have my old one.

I have just spoken to a very nice man who lives near Canterbury, and he has one. So I have just ordered a set of scales for cocaine laboratory work so that I can match weigh the pistons and gudgeon pins. :roll:

The saga continues!!

Ready with the patented lifter outer harness attached!
Rebuild g.jpg

And off to Baz's today for the next stage, which was - split cases and empty the bits out!
Rebuild h.jpg

Empty!
Rebuild i.jpg

And crankshaft.
Rebuild j.jpg


As I thought, the right end seal was u/s, but so was the bearing - and all the other crank bearings 'just' :? - and the 4 main gearbox bearings too, possibly due to the mileage when I got the bike -

plus another (about 3000 mainly high revving)
HAAAR FAST.jpg

pic taken after a fair run from Creg ny Barr at 104.6mph, 18410 rpm :shock: and nearly 5 to 6 (time) - although the tacho may be slightly ambitious!!
So the next episode will be after the crank is repaired and a spare gearbox is fitted with good bearings.
Nowt straightforward is there? :cry:

Had to 'nip' down to Baz's with Keith to pick up his happier 550 and drop off another 550 engine/gearbox to the (yet to be made happy' ) A engine.
Keith gorrit hooam and he nearly wazzed hessen about the difference but was happy about the end result. Was worth the £64.53 pence it cost him ....ish....I can't understand it was so cheap. :roll:
Whistle see about the A update as summat happens......
The wallet moths are trying to recover........ :cry:
