Just did a bunch of the standard mods. Charcoal can delete, flapper delete and battery replacement and finally a booster plug. After the flapper delete the engine had much less engine braking and it seemed to make shifting much easier and smoother. Pulled the tank and replaced the battery (getting noticeably worse)... and put on the booster plug. Took it for a test spin and the notch/snatch in a slow turn at bottom end of 2nd gear is basically gone. Bike seems to idle stronger and has lost the occasional pop from being lean, which by the way worsened after the flapper delete. It is certainly no race tune, but I am no racer. For a casual rider looking for smoother and easier to drive, I’d say it is perfect. I considered a Bren tune and just didn’t think I’d be a Real user of all the power. No doubt it’s the way to go and I may at some time in the future make the plunge. For now the mods have made a huge improvement in how my bike drives and my enjoyment.
