I probably misunderstood what you are trying to do.

Nevermind, he said ampersand... this one: &
And if I recall, maybe the board doesn't like that symbol for picture links.

It matters not. The idea was simply to avoid putting the whole email in as that sometimes make you a target for spammers. Doesn't seem to be much of a problem on the Ghetto though. We're probably too obscure for scammers. Either that or too weird.

As a newbie I’ve found this thread very informative. Regarding engine changeover, Kiwi Dave wrote: GRiSO - Motor#A813524 Build Date 12 April 2012
I’m ‘looking’ at a 2015 model. Would it be correct to assume this engine was rollerised new from the factory?
The owner has had it from new but strangely dismissed my camshaft questions?? Otherwise seems a cared for bike, albeit sketchy dealer service record, but low mileage.

2015 model should be factory rollers, but to double check simply ask the seller for the engine serial no which is stamped on a plate fixed to the motor, and check that it’s after the change over #

My engine number is A8014650, I believe it is a 2015 model. I purchased it new in 2017.
Using the VIN number to determine year of manufacture can be misleading, as these are issued by the local registration authority, not the factory. I did observe during a trip to the USA, some bikes on the showroom floor displaying a VIN of 2017, a bit of creative licence IMHO.

Hopefully I’ll get the engine number in coming days. If it matches a post roller head then I’ll go have a look & invite owner to lift a cam cover.
Out of interest does anybody know the cost of parts / labour for the roller upgrade?

A 2015 will definitely be a roller motor. No need to lift the rocker cover to check on a 2015 as 2015 and onwards Grisos all use the Cali 1400 sump which is one piece rather than the earlier bikes which have a sump and spacer. The earlier sump has a flat bottom. The later one is thinner at the front than the back so viewed from the side it is slightly trapezoid. If it has the later sump it is definitely a roller motor.
The cost of rollerisation depends on year and, to a degree, model. Some are simpler than others. I think I should actually produce a detailed post explaining the various changes that can be pegged at the top of the technical section.

Thanks for all the information. I have a noisy Norge. Does anyone know where I can get a Kit A in Australia to rollerise it?

I don't have one in stock at the moment because they are in really short supply but I can order one. Problem is no lead time due to the aforementioned supply issues.
