Front too high after fork rework

Previous owner of my RC51 had a fork rework done, now the front is much higher than stock. What options do I have to change this?
I thought of "lowering" the ride by moving the forks up from the lower triple clamp, is this a bad idea? I am aware it will change the whole handling, but I am an amateur rider so the bike will never go near it's potential.

Info on which parts have been used for the rework according to the bill:

- Preload Spacer Kit
- Showa 43/54/11 Seal
- Showa 43mm Dust Seal
- Suspension Tech Rebound Road & Track (2006RR)
- Suspension Tech Comp Road & Track (2006CR)

How do you define much higher?
Is your external preload adjusters all the way out?
Were the spring rates changed to much stiffer rate?
And were the preload spacers trimmed for the typical installed preload of around 17mm?

Unfortunately I don't have any other info of what has been done apart from the parts list on the bill.
I will check the external preload adjusters. Will also post a pic of the actual bike once I'm able to (9 posts already).

It's hard to tell from the pics, but are the forks just lower in the triple trees?

What is the fork lenght loaded IE rider sag? What is the fork lenght unloaded?
What is your front sag set to?
What is your rear sag set to?
Do you have aftermarket link?
Do you have an aftermarket shock?
Are you using a 50 or a 55 rear tire?
If you do not know any of the above then none of this makes any difference. Just go out and ride it and hope for the best.

Google and forum search for suspension set-up and sag. Read, learn, do.

Until you set up your suspension properly it is useless and potentially problematic to drop or raise the fork tubes in the triple.

Please excuse my condescension and general bitchiness. It is just that most of the questions concerning suspension and setup are falling into the definition of insanity.
I do not know of how to be of assists to you with out the information. It is apparent that most of the members do not know the information either, so I should not single you out. My apologize.

Thanks guys, I'm happy for any bit of info I can get.
I still think the 2 pics are useful for someone to be able to remotely figure out what could be going on here:
If you look at the orange side reflector, you can tell the fork tubes have already been moved up via the triple tree clamp to compensate for the significantly longer travel the forks now have (compared to stock).
This did however still not take the overall front height of the bike back to stock, as you can see by looking at the huge gap between nose and front fender.

Rear shock of the bike is stock, but it does have a 55 rear tire.

What I'm trying to say is I haven't come across any RC51 that has that much fork travel (55 rear tire or not). Have a look at the pic below, probably better than the 1st one.
Maybe they used fork cartridges that are way too long for an RC51?
Thanks again guys, any idea/comment is appreciated.

What is your fork lenght on the kick stand.
If the shop that did the work shortened your top out spring you should get around another 25mm of length on the forks.
The forks do not look that long to me. Longer then stock but that should be a good thing.
