From a very knowledgeable source, a renowned Guzzi dealer mechanic, I have learned that the "new" 6-speed V7's are showing some sever problems with the factory set-up of the crankshaft inside the crankcase.Apparently Guzzi is replacing engines and some dealers have already swapped out 5 or 6 motors. Has anyone experienced this snafu?
It's been covered here and elsewhere. Some V7II engines were assembled with a missing thrust washer/bearing at the crankshaft, and those bikes exhibit an unstable clutch adjustment, due to the crankshaft eating its way rearward through the soft aluminum crankcase casting. Although I haven't come across any official announcement, dealers apparently have been informed of the problem and are replacing the defective engines on warranty. We currently don't know how common/rare the problem is, I'm just glad it doesn't affect my V7II Stone, which has almost 14,000 happy miles on it.
Can clutch be adjusted properly if there is no thrust washer? I would assume that wire becomes to long otherwise...
Yes, the issue is ongoing. Piaggio is getting to the heart of this but problem bikes are still coming over cross the pond. Could be ones sitting on the showroom floor from 6mo ago now sold. Some dealers have had a few bad ones, some more than a few. Not to worry they'll be replaced under warranty.
What sort of mileage do you need to do before the problem manifests itself?
So is it all a case of improper engine assembly?
I have no idea if sealer is getting in rear main oiling holes during block assembly or if one of the crank thrust pads is falling out on assembly( the later happened in mid 80's).I'm sure that the Piaggio has pulled the bad blocks apart to look at them and sort it out. I have not inspected one.
This is the best I found in the service manual..
Don't take any risk and shift into neutral at the lights.Cheers, voncrump
...I wouldn't get all worked up about this folks. Piaggio is taking care of the customers, and the dealers are getting really good at crabbing the small tonti frames...
Question.When they replace the motor, do you then have a motor number that doesn't match the frame? Or, do they no longer use that system?
Nonetheless, it would be nice if Piaggio would go public with the problem, and specify which VIN numbers might be affected. I'm pretty sure that if this issue were to occur with an automobile, the manufacturer would be under some legal obligation to do the same, and probably issue an official recall.
