Ben, if you search the internet there's plenty of cheap motorcycle jacks available, get one with a couple of adjustable cupped legs and place these under the frame tube where the centre stand would otherwise fit. Something like this: To keep the bike upright I bought a front wheel chock like this one: This makes maintenance so much easier...

Ben, no not gone near the transmission oil as I’m attempting to get the harder things talked first! I’m still edging towards removing the front cover as I’m more confident finding tdc from aligning marks on the flywheel, assuming there are some. There won’t be oil flowing behind the cover surely? Not with the alternator in there?? There is a specific engine manual. Best we have a look in there too. N

That looks easier to deal with than a paddock stand motopete, many thanks, one of those should be appearing in my agent's office within 10 days.
I've got plenty of scrap to make something to hold the front wheel, although I'm wondering if the steering lock would serve that purpose -- we'll see. Looking forward to working on a perpendicular machine -- cheers.

I'm still wondering if there's oil in my front cover Nigel, seems some alternators do run in oil -- (Sounds messy!) I suppose loosening the bottom fasteners would answer the question with little loss. I'll be waiting for my bike-lift to arrive before I set to.
If I remember right, when a valve is closed and the gap can be measured, you can rotate the stem. The pushrod spends quite a large part of the rotation of the cam on the concentric part, so there's no need to be too precise as long as you avoid the lifting part of the cam. Turning the crank and observing the valve gear will soon reveal the way things go. On my last bike, a BMW R100 RS, I could set the gap by turning the adjustment nuts the correct number of flats from closed. That was a doddle. There was also a whole lot going on behind the front cover, to be carefully maintained -- chain tensioner, carbon brushes, adjustable timing etc, and I'm hoping for a bit more knowledge before I see behind mine. More chance of doing a complete job in one go ... |

I don't know about the V7 but my VFR alternator ran in oil, I put the bike on it's side-stand before removing the cover.
it's not messy in the VFR design, if I remember correctly the coils are static with just their toes dipped in the oil and the circular iron magnet rotates. I may be mistaken, it's been a decade since I was in there. What it does mean is that you must be scrupulous about removing the old gasket & fitting a new one else oil leaks will follow. Tony

That's interesting, I must notice the difference between the height of the sump and the front cover, and work out just exactly where the oil is -- in relation to the alternator.
Nothing which comprises my present manifestation was here a decade ago, little wonder life is so confusing.

Not a chance, the valve spring holds the valve closed so no way could you rotate the stem. Rotate the push rod, yes, but why do you need to?

Oh the shame! I meant the pushrod -- honest I did.
My understanding is that if it rotates freely, it means it's on the back of the cam and therefore the valve is closed and the clearance should remain constant until the cam starts to lift. |

You can do that on any screw type tappet adjuster if you know the pitch of the screw. I don't happen to know what it is for your bike (someone hopefully will) but if it's say 0.8mm it follows that a complete revolution of the screw will equal that. So if your clearance should be 0.15mm, you would tighten the screw till it was touching then back off a touch less than 60 degrees. However, it's very easy to use feeler gauges on the Guzzi.

Yes I'll definitely be using feeler gauges Ian, initially at least, and I'm looking forward to getting to know the bike properly. The 5 years since I bought the bike have been a bit of a whirlwind, but now I can hopefully sit back and look after my V7, my fruit trees, and my cat.
We're getting an average of eleven and a half hours of sunshine per day this week, and as my granddad used to say - "It's a hard life, if you don't weaken." Hence "Spanish Yoga" also known as the siesta. There's a ferry to Santander, and then it's all downhill ...

hi All. Confirmed, we definitely have oil behind the front cover. The alternator runs in oil. Happy days 🙄 You keep talking like that Ben and you’re gonna get a lot of visitors 😀

Nope -- I checked on the globe , it's definitely all downhill.
Especially when you're approaching 70, and I don't mean MPH ...

Regarding my planned foray into the timing chest, I'm wondering if there are alternator brushes to be examined and maybe replaced -- gaskets that should be on hand (or is silicone sealant a good alternative?) -- chain tensioners to be checked -- anything special to look for ...
Since Guzzis are scarce here, sourcing the parts may prove 'interesting.' All advice welcome.
