What a ride home

I just want to thank you guys again for all the work you did on my bike. I didn’t realize how rough she was running until the ride home Saturday arvo, the acceleration is a heap smoother and quicker (had to check myself after reaching a ton fifty kph overtaking a road train without cranking it on like I had to before lol). I was made to feel welcome and that is also very much appreciated.

Feels like it wants to pull the tyre off the rim.

Deno, after the dyno the fatboy is a completely different bike to ride. Feels like it wants to pull the tyre off the rim. Cheers again

You guys did the cams, breather and pipes on by ultra, bloody hell the thing goes like a rocket. Might have to move to the Northern Territory as the sweet spot is now 140 kph. Thank you guys, great job…
