2007 Norge - transmission backlash

It’s a long time since this post but here’s hoping …
My Breva 1100 suffers from bad backlash especially in traffic. Can someone with more tech knowledge advise me where to get a fuel compensator and how/where it should be fitted? It will make my riding SO much more enjoyable if the problem can be eliminated.
Thanks in advance.

Tony - see my Gutsi Bits Fuel Booster post in January. It has transformed my Norge 8V.
