Timing Mark

[BrianG]

I cannot, for the life of me, find the timing mark on my 2000 V-11 Sport. I did the clutch last year and was careful to realign the flywheel to the position in which I found it, but it did become apparent that the clutch had been done before I got there, so I guess it could have been clocked.....

 

Is there some mark I am missing?

 

I can do the degree-wheel / piston stop method to determine a new TDC mark for the current position of the flywheel, but I'd like to avoid this PITA proceedure if possible......

Brian, there's no timing marks on mine either, only TDC marks for D (right) and S (left).

 

Are you saying these are gone?

 

Isn't the flywheel indexed to the crank?

 

In any case, if you're looking for TDC to set valves, getting it "close" by feeling thru the spark plug holes is plenty good enough.

Brian, the V11's don't have timing marks. You should have a TDC mark for each cylinder and also another line or arrow on the wheel which will align with the centreline of the barrel when viewed from the back of the crankcase with the gearbox off.

 

For setting the valves you can, as Ratch suggests, just get the piston close to TDC compression, a few degrees either way will make no odds as long as both followers are on the base circles of the cams.

 

If you want to accrately find TDC without the botheration of degreeing and dead-stopping you can use a bubblometer which can be surprisingly accurate if you use a nice thin tube.

I can't find TDC marks or anything through that little hole in the bell housing.

 

So, absent timing marks, how do you set/check baseline ignition timing?

 

I didn't see anything that would index the crank flange to the flywheel, but then again I wasn't really looking because I made my own paint marks on dis-assembly, so it buttons up exactly as it comes apart. It wasn't until I was looking for timing marks (TDC), after reassembly, that I discovered that they weren't where I expected. It runs fine so it's no big deal.... certainly not enough to crab the bugger again.....

The good news is, there's no need to check it. Now if you want to re-program it, there are those hereabouts who will be pleased to advise how to do this with devices that cost more than several used moto's I've had and enjoyed for years. To each his own. Timing is pre-set, triggered off the phase sensor on the cam sprocket, and regulated by the various sensors.

Sweet.... another maintenance item out the window!

 

Almost makes sync'ing the TB's and setting the TPS worth the exchange!

Perhaps after I get this sorted.... Reprogramming new ECU maps sucks! ....................................but forced induction is nice !!

Hey porsche with a snoter puffer is very cool and fun. Never got to play with a supercharged one. Thats a 928 right? One of my techs has one there pretty nice but a nightmare when they break down.

They are like any other 80's high tech exotic that operates on relays.......... a stupid PITA to troubleshoot.

 

My goal is to take this '87 928 from the stock 330hp to 500hp @ 10 psi....... What's that I hear ticking???

That will bring the kg/hp ratio just barely in the lines of your Guzzi

Well, thanks a hell-of-a-lot raz!!

 

Makes all the effort seem so worth-while!!!
