Default 2020 Harley tuning & big bore kit

We have a 2020 Road Glide in our shop this week. We are doing some Dynojet Power Vision tune validation and a FM 128 big bore build. Stay tuned!

shouldn't that be a 128 kit on a 114?

I would love to do a 128 kit on my bike but since it has 34k miles on it I am not sure thats a good idea

Yes, it will be a 128"

Would not worry about 34K miles if the bike is good service condition.

Jamie, curious how the stock RG Limited, which is twin cooled and running at higher compression would look like? Probably not a ton, but maybe a couple HP and TQ?

This chart confirms for me what I feel when I ride that the TQ falls off pretty quickly after 3500

Edit - never mind. Same CR as the special. Odd that it reports 1 less HP for the Limited.
