Yes big difference. The bike is now much better, and doesnt really surge at all now. Its not 100% but its a different bike to the one I collected from the shop a couple of weeks ago.

Which is good for two reasons........

1. I now dont have to drive the bike through Yamaha's shop window.

and

2. My planned purchase of the OTR 2-into-1 system can now go ahead as planned!!!!

(plus the rear LED light converion, the mini LED indicators, the fitting of hand guards, new super-sticky tires, the fitting of a rev counter etc etc but please dont tell the wife!!!!!)
