Along with “hold my beer”, a few words that lead to all sorts of fun.

Good work so far Nin. Now here's my dilemma, do I check on this post every day? Or, do I leave it a month and have a feast?

 

[Nin]

Cheers Wrinkley, much appreciated. After the weekend I’ll not be updating this daily, but everything in moderation eh?

I’d say Mondays would be a good day for your fix.

Anyway, a late start today, and a bit of breakfast reading.

Hmm, what’s all this then?

Nothing obvious behind it.

At a guess, An owners idea to fill the gap in the casing, hoping to stop the engine bolt seizing.

 

[Nin]

You could be right there.

Whenever I start working on a bike, especially an old one, I begin to get a feel for its life and history.

You can tell from how the fastenings have been treated, whether any of the fins have been dinged, what type of parts the consumables have been replace with etc.

So far, only that woodruff key and the silicon sealant have raised any questions. Otherwise, it’s looking pretty straight.

Famous last words, no doubt.

the front engine bolt is the bane of big block Guzzi owners, a seized bolt usually means a hacksaw and new timing cover.. I used to fill the slot with grease.

Ah that explains it then. Everything points to this bike being owned by Guzzi cognoscenti.

A nice leisurely breakfast Sumatran dark roast coffee (courtesy of Roast and Post. Which sounds a bit like a porn site).

Then mowed the lawn, walked the dog and did a few jobs, enough to get the afternoon to myself.

Today’s job is to strip the engine back to the bare casings, and take a good look at the internals to see what needs replacing.

Here’s our starting point

The next head comes off pretty quickly, no problems here.

Then the barrel. This is a crap photo but you can see it’s fecked, the chrome has come off the bore.

Everything else is in really good condition though.

You can see the cam followers, one in & one out.

They mostly look in pretty good condition.

This one has some small pitting though. I’ll run it as it is and see how it goes.

Then onto the oil pan.

That DID NOT want to come off. But lots of heat and special service tool No 1 and we persuaded it.

I fear I’ve missed a service and my warranty is void.

All cleans up nicely, just a wee bit of damage to one cooling fin.

Now it’s time to pop the crank out.

Bingo. Again all the bearings and seals are in excellent condition.

And there we have it. Pop out the cam shaft and oil pump, and there’s a set of casings for Mikeyboy to work his magic on.

Well worth it,fuggin great thread Nin

I know nothing about Guzzis at all so when I saw picture 4 in post #99 I thought ‘that oil filter is well hidden’ (top of picture looks like an oil filter mount). Now it looks like you have to drop the sump off to change it! No wonder it’s not been done for 11 years.

I remember looking at a Stelvio in a Dutch showroom and thinking What a faff to have to remove the fairing to get at the oil filter.

As ever, I’m sure I’m adding 2 and 2 and getting 3.

 

[Nin]

Nope Shakes, you’re spot on. It’s a sump drop to change the oil filter. Got to love those Italian designers eh?

To be fair the bike hasn’t turned a wheel since hitting just over 50k miles so it’s not really a problem, and looking at all the bearing faces you can see they are in good nick.

I can buy an additional sump spacer that includes machining for an external filter, but I don’t want to spuff nearly £200 on that when the silencers are £499 a pair!

Here’s a better pic of the chrome flaking off the bores.

It’s a shame really because otherwise they are in excellent condition.

Nevertheless, new barrels and pistons on order.
