Currently running a stock 07 GPR1300, and would like to improve performance for next summer. I am looking for do's, dont's and special tools needed to upgrade to a stage I kit from Riva.

someone posted these semi detailed results a whole back on what mods gave what gains. These are jnot riva stage 1 kit mods but mods that the members here have proved over time work rather well.
these seems to be quite popular mods with the crew here and you can see pretty clear what you will get out of them..
06/07 models are the same so it applies..
'06 GPR stock = 64mph
Modded riva plate,800 grate, stepped sponsons = 67-68mph 7200rpms
PPK, dynfly 14/20 = 70.2mph 6880rpms
D-plate,race F/A, EFI controller = 72mph 7080rpms
Riva heads trim all the way up&superman = 73.1mph 7100rpms
Added package,VF3 reeds, but had a handling
problem, could not superman or trim up
and still running the riva plate = 74.2mph 7240rpms
14/22 prop but still had problems (bounce) = 74.5mph 7150rpms
Tried Free flow tube = 73.1mph 7080rpms
Put Sound suppression back in and found my = 76.4mph 7130rpms
Added Keyway and more plate/tabs adjustment
for full superman position = 77.8mph 7200rpms
another proven list of mods to add to a gpr are these
Sonic Boom Ported Throttle Bodies
Modded R&D Rideplate by Jim or Carl
Hope this helps, i dont think from what i have read the kits from *cough* are the best way to approach things...
Anyway I am just getting started myself so i cant say for sure these are perfect but it is the general consesus from the members which i kept handy so i head in the right direction...make up your own mind though.

dont be in a hurry to purchase a stage kit from riva......you can piece together what you need on here quickly, save some money, and have better parts............
tunnel reinforcement should be 1st on your list
