Found another dyno video of the V4 that I wanted to share. This one shows the results at the end. Not really sure that I like seeing the stock exhaust shooting flames, and that chain seems to be all over the place.
It's hard for any regular person to capture sound correctly. If you look at how video game companies record sound of cars and bikes, its quite intensive. Even with all that equipment to capture it, sometimes how the end user is listening to it needs to be rewroked as well.Bike is clearly running a little rich, not sure if they have done anything to it, to try and increase its dyno performance. Wish the microphone was better quality, so we could get a clearer sound of the bike.
