The ‘79 California Rebuild Thread

[ianboydsnr]

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.

It sounds like a faff, but it forces you to clean out the sump at every filter change, and you do often find a bit of oil mayonnaise when you do,

It’s not very hard or involved to do either.

Newer models are like the R1100 models with the filter recessed into the sump.

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!

I have one of those fitted to my lemans 2, waste of money, if you were doing 500 mikes a week it would be handy to have, so you could change the filter every 3 months,
Better to spend the cash on a sump spacer.

Just did, and just got up off the floor. New followers added to the list.

I stripped a Looppframe once where the plating had gone a fair way down the bore, but was a smooth transition from chrome to ali. It ran fine and had decent compression too. Amazing.

Never stripped one where the followers don't look fucked, and I always replace if budget allows.

Don't forget the crank sludge trap. It will be full

whilst you have this handy , measure the pin that goes thro' the pivot , then drill the casing 0.5 mm bigger , and the arm .

Just checked, it’s been done already.

It’s been properly looked after, this one.

engrave a mark, where the white paint is on the crank ,( pic 2 this page ) also on inside of the flywheel , they are balanced together.

Good call Balders, thanks, done.

Well we’re properly committed now fellas. My first £1000 plus order of parts just landed with Stein Dinse. About half of that is the new barrel/piston set.

Unfortunately they don’t do the 83mm barrels any more, only the 88mm so the bike is going to be a 949cc now.

Next step is to get started on the front suspension and brakes, and get the wiring loom fitted to the frame. That should be a laugh.

Part of about £70 of Boltbase order ...

Ah there’s nothing like a quiet evening in, fettling your brakes.

This was the starting point, all a bit skanky and not been moved for 10 years.

A bit of brake cleaner, heat and fiddling, and a happy evening cleaning. Quite pleased with the end result.

Now waiting for the new hoses, pistons, banjos and various repair kits to arrive.

Right, poll time. What’s the collective’s view on finishing these fork legs?

They’re in reasonably good nick, so I could just wash them down and leave as is (my preferred option).

What would you do?

Good deal grease and leave as is

 

[ianboydsnr]

If your getting the engine vapour blasted, then do the same with the forks, otherwise they will stand out, if your just cleaning the engine, just clean them, it’s one or the other

 

[Oldrat]

Agreed, send them to Mikey.

 

[ChasF]

Yep, once you go the vapour blasting route you’re committed to get all the alloy finished to the same standard.

 

[Nin]

Good advice chaps, into the “Mikeyboy” box they go then.

...and everything else.

 

[Lord Snooty]

Agreed with having them vapour blasted, otherwise when the bike is finished your eyes will always be drawn to the forks and you will regret not doing them to the same standard.
