Short of a complete rebuild, all the tools you are ever likely to need are listed in the sticky

Torx E8 (for adjusting the shift lever).
Adjusting the Gearshift Lever
1. Undo the plastic cover above and to the left of the gear selector for access for the rest of the job. This looks to be the starter motor cover. There is only one bolt to undo on the right and there are plastic lugs on the left hand side so once the bolt is out slide the cover to the right to disconnect the lugs then manouvre out.
2. The gear linkage consists of a threaded bar connecting the gear selector shaft to that of the gearbox. There are locknuts top and bottom. Undo both locknuts and move one up and the other down until they meet. Now lock them together. This operation will probably require a bit of WD40 to ease.
3. Now using a spanner on the locked nuts turn the whole threaded bar anti-clockwise so it winds upwards. Eventually it will wind off the bottom lug and the gear selector will drop.
4. Now the adjustment is done, so either wind more of the bar into top lug to raise the position of the selector or wind the bar out of the top lug if you want to drop the selector.
5. Now raise the selector and wind the bar back onto the bottom lug. Make sure there are enough threads in the bottom lug to secure. At this point you should check the position of the selector by sitting on the bike with your normal biking boots on. Also check that the selector does not foul the sidestand movement.
6. If the correct position is found, wind the locknuts back up to each lug and lock, then replace the starter motor cover making sure not to pinch any of the drain lines that run down the back of the cover.

Getting rid of the Torx E8 and E10
To deal with the handlebar mounts, and the shifter, you normally need Torx E10 and E8 sockets, respectively. The E-series Torx are not generally available, though I found a set a local auto parts store. You can use a standard 8mm socket for the handlebar bolts, so that's one less tool you need in your kit. I built a custom mount for my GPS, and in doing so I replaced the Torx handlebar bolts with hardened 12mm hex-head bolts.
BTW -- you can remove the E-8 Torx bolt in the shift lever with an 1/4" SAE socket or box end wrench. Either 6 or 12-point.
You can buy all the bits and bobs in Halfords.
You will also find a heap of other information in the same place on just about any topic you can think of.... failing that, it's rare that Search on UKGSer does not turn up anything.
PS You have a new bike so you do not have a starter motor cover.
When I took a bike out for a test ride I found the gear lever a touch too high for me, and I'm assuming you can adjust it like all the other bikes I've owned? If so is it just a matter of loosening off a couple of nuts and twisting the arm/rod? What size spanners do you need?
