Ok see below from the manual, W5M51-1X7A .. gearbox codes can have either the 'A' gear set (GSR) or the 'B' gear set (RS) They seem to all have the 4.529 final drive but possibly could also have the shorter 4.875 final drive, so its a bit of a lottery, Set B with a 4.875 is very short but could be substituted with a 4.529 to make it longer, or you could change 'B' set 5th gears for an 'A' set which would also help. There are a few possibilities but you would need to find out what is in there first to be certain, which is basically a tooth counting excersize !
I may have some spare parts available depending what you would need .

W5M51-1-X7A Gear set A Final Drive 4.529
W5M51-1-X7A1 Gear set A Final drive 4.529
W5M51-1-Z7A Gear set B Final drive 4.875
W5M51-1-Z7A1 Gear set B Final drive 4.875
W5M51-1-X7A2 Gear set B Final drive 4.529
W5M51-1-X7A3 Gear set B Final drive 4.52

You have an Evo 4 GSR ratio box, which will feel really short on a Legnum! What you need is a higher ratio 5th and a 4.11 final drive.

The 5th ratio you have is a 0.761, and you require a 0.720.
