Okay,... if you are going to a mechanic... tell him you want the Versy modded adjuster installed, and in the extended hole if it will reach... (if the stock adjuster is more than 17mm out, it should be able to use the extended hole)...
What you don't want is a new camchain.... that will require double the install time, and cost.... and will waste useful remaining life in your original camchain...
Some mechanics are quick to catch on, and will see the improvement of the design instantly... others are sticklers for factory only equipment, and think anything different is voodoo...
...(assure him, this is a tried and tested, quality upgrade)...
Print out a few pics of adjuster extension measurements, and second hole attachments,... etc,... so he can grasp the measurement points, and how the second hole works...
Study up, on the installation instructions we have in the Tech Section,.. so you can be a knowledgeable customer...
Hiring a mechanic to do the job, is almost as hard DIYing it... (you should still have all the info and knowledge,... you're just paying him for his expertize in turning wrenches... Hopefully, he won't break anything, or strip any threads, or forget any parts)... good mechanics seldom do...
... bad mechanics can make F'ing-up into an art...

EDIT.... Jeez!... I just spent all this time, single finger typing this ... and JC beat me to the post,... and did it in a simpler, and more concise, prose...
Nice work JC...
... darn you!...
...
I'll leave mine up, too... in case it has a morsel more info,... and, because I just spent all this frikkin' time typing it!...
