2012 GRiSO Engine Noise - Anyone know what this is?

The techs found oil leaking at the bottom of the cylinder. I'm going to have them stick to the plan and then we'll have to redo it later.

These guys are having trouble getting the new cam assembly in.

He said there is something that doesn't make any sense as to how this interface works. He doesn't want to put it back together with the new parts until he can make sense of it so as not to cause any damage. Anyone in the know want to give them a call? Gemini Motorcycles of Sterling VA.

Please, tell us that these guys don't have an ego that will make them discard viewing all the tech steps displayed on this Forum by Pete about that swap.
Unless there are bits missing in the kit (not that uncommon), it's actually a straight forward job for a professional. Guzzi familiar or not.
Make sure that they actually informed themselves about the task at hand. If not, they're not reliable.

I talked to the guy, he did his homework. Something is going on with the rocker arm and pushrod thats on the bike and the tappet in the new assembly. The new tappet has a flat top, but the old one has a knob on it. I'm looking at the part list and the only one I see is the knobbed one. 873631 vs. B015681 . I'm looking at page 72 in the part manual on AF1 racing and the kit A doesn't come with a Rocker Arm or Push Rod. Do you reuse the old one? Why is the tappet have a flat tip on it? It doesn't look like it works with the current control arm. I get there confusion... it looks like if he moved the rocker arm over, it will be like putting a square peg in a round hole. He's only concerned about damaging the bike. I respect his decision to stand down and not make any assumptions.

They've moved on to another bike for the moment until I can get this sorted out.

He's hoping Peter can contact him to help him move forward with it. It looks like somethings missing from the kit, but looking at the kit, I got everything that was supposed to be in it.

Shit man, you might need other/different bits...
Maybe you need part of the B kit after all?
I always been confused about all these different kits for these bikes.
My 09 needed a C kit since it was an early model but I totaled it before I could do the job. lol
I know that some dealers back in the days weren't even sure what kit was needed for the later bike before it went to roller tappets.
It happened sometimes mid 2012 so changes made within the same year add to the confusion.

Anyway, Pete will sort that out for them I'm sure.

You need these Pad

Look here [You must be registered and logged in to see this link.]
Pad is number one.

As I said by PM in the box with the cambox there is a bag, (Yes, it's there, we double checked before we sent it.) that contains two hemispherical steel 'Pads' that fit into the rockers that allow for the sideways movement as the rocker arm moves through an arc and the tappet only moves up and down.

The rockers are swapped from the old cambox to the new before they are installed on the head. When the  rockers are swapped and the retainer plate is reinstalled on the new cambox there is a new earthing tang that goes under the heads of the two retainer plate  bolts, the old one off the inner rear stud is discarded.

Before the new cambox is installed make sure the two locator/oil delivery dowels are swapped from the old cambox where they may of remained back into the head, (These are on the front inner and rear outer studs from memory, (It's three thirty in the morning here so bear with me!) and also make sure that the plug tubes that go between head and cambox are in the head, not stuck in the old camboxes. There are also o-rings that need to be put into the grooves in the cambox casting that the tube fits into to seal them. Lube them lightly with rubber grease on installation.

Getting back to the hemispherical pads, these are stuck into the newly transferred rockers with grease and then you hold the rockers so that the pads can't fall out as you slide the cambox down over the studs until it locates on the oil feed dowels in the head. I hope that they remembered to loosen the two 6mm bolts, (8mm hex head.) bolts at the back of the cam chain tunnel before releasing the tension on the main head studs? If not there may be problems with leakage as the head may of warped.

Once the cambox is back in place the main stud nuts can be torqued to 30ft/lbs in two steps before the 6mm bolts are re-tightened and the two rocker retainer plate bolts can be finally tightened to 20ft/lbs. loosen the valve adjusters right off and make sure the rockers can move freely once the cambox is installed before setting the valve lash to 4 thou inlet and 6 thou exhaust.

Look, if these guys are really having a problem we can work out a time and I can face-time them early next week and talk them through it but I am not going to enrage Jude by starting an international call in the middle of the night and anyway I go to bed naked and wouldn't want to trigger an international incident by traumatising some poor young pup in the US with the accidental vision of my flabby white carcass half awake and scratching my balls in the middle of the night!

And no, in response to the other posts. He has the correct kit and the pads are in there. Tell them to double check the boxes as, due to having had issues with missing bits before, we ALWAYS check before we send! (This kit did come from us didn't it? I'm not confusing you with someone else?)

I got it from AF1 racing

Thanks for chiming in folks! I sent a link to here so he can read it

They're going to resume next week.

I called him, hopefully it's sorted.

OK, all good. I've sent two kits to the US in the last few weeks. I thought it was one of them.

Anyway after I explained it he got the drift.

I ordered a fork rebuild kit from AF1 and it was a mess...
Some parts were missing and other were duplicates. lol
Good thing that the Showa 43mm fork in popular, I was able to source the rest of it locally.

So I would not be surprised if they fukked your order all up.

Let's hope not!! Thanks for all the help! You guys are the best!

Pete is.
I'm just jazzed to be on the show.

With Piaggio stuff it's often not the shop's fault if stuff that comes in 'Kit' form is missing stuff. I often wonder if their spares packing facility in Noale or wherever is run as some sort of sheltered workshop for the afflicted? One poor sod contacted me recently about a kit he'd bought and it had two left hand camboxes in. In fact I had one like that a few years ago too. I've also frequently had bits like shims and hemispherical 'Pads' and o-rings missing. It's why we are stupidly zealous about double checking everything nowadays and why, if you get a kit from us, you'll find the boxes the camboxes are packed in have been opened and their contents disturbed!!

Oh, and the oil leak is highly unlikely to be the base gasket. Tell him to check the breather hoses where they connect to the condensor box behind the steering head and the horrid rubber 'Condom' on the spare spigot of the box as well. Both are prone to splitting and leakage which will drip down the front of the block. If you look at the pics you can see that the oil is coming down from above the base gasket line.

I'll check it when I get it back. If need be I'll make another appointment to get it fixed. That's great news, hopefully it's something that simple

Yeah, small bits are easy to drop/lose...
People at the factory have their eyes fixed on the clock, not in front of them. lol

As for the pieces I needed for rebuild my fork, each of them were in their own plastic bag and were thrown in a small cardboard box from AF1, not Piaggio.
They did put the seals in there and that is what I needed most. I got the correct braces separately.
Good thing that it was not expensive...

Oh yeah, the condom thingy... mine disintegrated on my 09.
So it definitely could be one of the culprit.

Thanks Grisonut!

This is what came in the kit

The bags top right in the pics have the hemispheres in. Nope, that's a trick of the light. They'll be in the boxes, with the camboxes.

The bloke found them I think when I was talking to him.
