Did they drop the sump for a clean out? If not it's worth it.

As I've said before I've had three bikes have bottom end failures after rollerising, mine, Ralf's and Mark III's. Why these and no others I don't know but I have my suspicions and photo's that would back them up.

The thing is though the attrition rate isn't high so I think you can say with a reasonable level of confidence that once fixed they stay fixed! I'm certainly not fretting about my 108,000km Stelvio that must have had at least two sets of flats go udders skywards in it in its life! Also, having just undertaken what amounts to a virtual complete strip of Wyno's 100,000 Km GRiSO it is very satisfying to see exactly how good everything is inside a high mileage roller motor. Once it's all back together I'll write a synopsis of what we've done and what we found.

Hmm that's a good question, not sue will check with the workshop who did the job. if not guess its not a massive job to do. As you can see from the pic there was a lot of wear on one of the tappets it was slightly dished, guess that metal is somewhere! didn't get to see the condition of the right hand side tappets but presume they would of been the same. Also now it's a roller, probably time to invest in a Beetle map!

Dropping the sump is a matter of undoing 14 bolts around the perimeter and four up in the well where the filter lives. Get a new sump gasket before you do it in case the old one rips.

The shit that comes off the tappets is barely bigger than microscopic. Don't bother looking for it, just give the sump a really good wash out with kerosene/paraffin, check the strainer's for crud and reattach the sump. Put on new, pre-filled, filter, add oil, go!

Ordered 2 Kit C, expected delivery in 15-20 days!

We are doing parallel rolletarisation, GRiSO and Sport1200.

I guess Pete would recomends me as "Persona non Grata" in Australia for the questions that folow in his inbox Smile

I think Pete (I hope) would welcome questions asked before things go to shit, rather than assisting to pull you out of shit of your own making. He just wants the best for the bikes we ride (well CARC Guzzis mostly) despite the ignorance of the powers that be in Piaggio.

Reminds me of what happened when BMW first brought out their oil heads - problems galore. Despite the efforts of many of the dealers in rectifying these faults, at their own expense, they all got shafted by BMW and had the dealerships taken from them. Not because they went out of guidelines, but because they were all mechanically minded and got the job done, showrooms were grungy. The problem was, BMW wanted big shiny showrooms with salesmen in suits. Heard that before, I think.

Pete was doing such a good job of keeping the brand up and running, they (the new importers) took the service centre from him. Bah, suits!

By the way, I have 4 suits, some of which get exhibited for select occasions - usually job interviews and funerals.

Not quite Tony, I bailed out. John at Motocicolo had some PS sales droid in a couple of weeks ago and was saying I was still on board! Laugh? A bit of wee came out!

Not at all, as Tony sez I'd far prefer to help get it done right than have to try and fix a fuck-up from half a world away. Probably the hardest part for you blokes will be removing the valve springs as you do need a much smaller than *Usual* valve spring compressor. DON'T loose the collets! Very Happy

Sorry Pete, I misunderstood your situation. Are you in fact looking to pull the pin forever? What is on your horizon, apart from you and Jude travelling widely?

Pete

We do have a friend, a mechanic guy which has universal service (cars and bikes), so we can use all the tools. If he doesn't have that valve spring compressor, we'll have to figure it out.

I've allready read the link you sent me from wildguzzi, a bit mixed up topic, but i believe i can get the most of it. Bad thing is, i have to translate and rephrase it Smile

As long as my hands hold up, (My arthritis has really kicked off in the last year.) I'll be around for a few more years but I wasn't going to sign up with PS. They have a long history of screwing people over and being spectacularly useless and venal. Not my MO, I want nothing to do with them! I've just gone back to being freelance. Funny thing is I'm busier than ever!

General purpose compressor seemed fine (in red box behind head and has various options) - got mine free from mate going ex-pat to dubai but he paid buttons. [You must be registered and logged in to see this link.]

Drained the oil, Dropped the sump and cleaned it out, lots of little shiny bits! Cleaned the strainers. Replaced with new gasket & filter. Hopefully that's it ,Bike is running lovely since rollerisation only fault is that there is no warm up rise in rpm from cold starts, but starts fine and idles fine. Guess my next job is investigating the stepper motor? :/

KIT A Vs KIT B

For those in the know.
Why is the KIT A so much dearer than the KIT B.
I have been looking at the pics of the kits on TLM and can't see a huge difference in what is delivered


I suspect I can't get around paying the cash as I have a 2012 engine with the floating rocker covers, more curious to know the difference or if I can get around the additional cost....

Not really. I have no idea why the costs are so different, it's not as if there is a tremendous difference in the machining costs. I think it's just weirdness in pricing policy by the factory.

You can use a 'B' kit but you'll need earlier rocker covers and long plug tubes to achieve it.

Buy the 'A' kit through me and I'll knock another $20 off for you. Shipping will still be the same.

I ordered the C Kit on my own dime, and I am ready to put it into the 2009 GRiSO that I recently purchased (less than 7,000 miles on it). I am going to do the work myself, and I am really looking forward to it -- I'll probably start this weekend.

I'll post pics, including condition of the old flat tappets. (I'm hoping to see just enough wear to know this was worth doing, but not enough to suggest any engine damage Smile )

I have another thread on this too: [You must be registered and logged in to see this link.]

So far it's going well: I've got the old cambox out of the left side, and am ready to remove the head.

Here are pics of the flat tappets. Looks like just what I was hoping for: the wear has just started but doesn't look like too much damage has been done.

Moved to GRiSOlogy as the topic is more geared towards wrenching than riding...

Hey GuZee, I see from the photos of the tappets and cam you made a wise decision to strip them out when you did Thumbs Up

Otherwise they do chew themselves up pretty quick when they get started, good intervention. cheers

Yay! Logically I should hope for ZERO wear for minimum crap in the engine, but it is nice to see the reason I am going through all of this effort and expense Smile
