Gents,
 
Seems I need to remove and re-install my dizzy.  I had a late look last night in the manual and it says you can't remove it with the engine in situ.
Can anyone confirm this is definitely the case please?
 
If it is, please break it to me gentlyConfused!
 
Regards

Relax. No problem removing the Dizzy.
No need to remove much except the R/H carb for easy access.

With the dizzy out of the way, if you have the original airbox setup, the opportunity to put in a new air filter is not to be missed !

Here y go set engine to TDC on cyl D = rhs .... Tank off,  carbs off , undo the bolt on rhs the one you can see, I have a long handles 13mm spanner i get in from opposite side helps to have the C clamp that holds it so the open end is up on the left the factory tool is a 13mm spanner bent at a right angle with long handle but I have used my long spanner for years, it is fiddly .... hope this helps to be fait The Haynes manual ig good but the either blue or yellow covered Guzzi one covering the V1000 Spads/G5/Convert with added bits for Le Mans and with the blue one Cali 2 fills in the gaps .... once you get TDC make sure the flywheel marks line up I overpainted them in white and yellow for S (left) Hope this helps

Thanks for all replies so far chaps.

Bit confused though.  The manual shows D as RH piston at TDC.  Then line 2 as retarded timing mark and mark 4 as advance timing mark.  As they are both to the one side of the TDC mark, how can one be retarded and the other advanced?  Surely they can only both be the same (retarded or advanced) but varying degrees?

I need to adjust the meshing of my dizzy gears with the flywheel, and the Haynes manual states get RH piston on the comp stroke and the static timing mark aligned but it doesn’t say which this mark is?

Looking at another thread I believe the static timing mark is not the line directly above the D but the one above it?  In my case this would be the 4 line. BTW my D & S don’t have lines, just the letter.

Am I OK so far please chaps?

Regards as always

Just looked at the Pete Roper guide and the static timing mark is the line ABOVE D & S

Semantics ! Retarded = Initial advance (lines 2 & 3)
                  Advanced = Maximum advance (lines 4 & 5)

So they're both on the same side of the TDC mark.

To re-time the dizzy, set the flywheel at line 2 with RH cylinder on compression stroke, then push in the dizzy so that, when fully in, the RH (top) points can be opened by rotating the dizzy body.

You can't time the ignition with only the TDC marks (D & S), you need the lines !
To guide you, the interval between 2 flywheel teeth is 3.75°.
Initial advance for the V1000 is 2°, so a bit more than 1/2 interval above D or S.

Before you move/remove the distributor body take the cap off and have a good look at how things line up, you don't say whether you have points or electronic but you should be able to find or mark a reference point/line. (It's best to set the engine to the static timing mark on RH cylinder - that's the first line just above the D mark) If on points the points cam should be just about to or just starting to open the points for the RH cylinder then.Also mark the position of the distributor body relative to the crankcase.
Now with the clamp removed you can lift out the distributor.
Be aware that the shaft will 'skew' as you pull the distributor out and it will need to be re inserted in a position which allows for it to skew again on the way back in. Refit and realign the body to crankcase mark and with this done see how things line up within the distributor, if you've been lucky first time then that will also line up.
Provided that you don't turn the engine at all whilst distributor is off then returning it so those points/marks made earlier line up again will mean you have correctly reinstalled it. If wrong it will be noticeable because it will be wrong by a whole tooth of the gear so it's either right or wrong.  If you get it wrong first time just lift up until free of the drive gear,turn the distributor shaft a bit in the direction which will correct the error then reinsert to try again,to be correct both the body to crankcase mark and the marks within the distributor must line up.

Thanks to everyone for help.  Its very similar to my Stag & in some respects to an early Wing I restored a few years ago.  Hope to get an hour tonight at about 10pm to at least get it installed correctly.

Dizzy re-installed OK and all timed up nicely so may get to start her up this weekend.  I did the valve clearances at the same time.  With the exception of the RH inlet having 5 thou' clearance, the remainder only had a couple at best!
 
Cheers for now
