  1. Throwing some more data points in. I rode mine all the way around San Diego yesterday, including Sunrise Highway, over several hours, and included a stop at @sfdownhill's to show off how his creation is getting used on my bike 😄 So riding between sea level and 5,000 feet, mostly highway speed and 30-60 in twisty highway stuff. It was 78-80 most of the time. I haven't touched the Rapidbike since installing it before the headers and Delkevics, and my bike really needs some injector work plus starter valve sync, etc. just to give you an idea of how it is right now. I'm also only using the stock narrowband sensors. But I still managed 42mpg with saddlebags, which equals what the bike got when new (42 with, 46 without). It hasn't seen quite that good mileage in a while! It also managed to keep temps lower as it wasn't working as hard. At steady speed it was pretty rock solid between 174-180. Performance wise...wow. There is little to no resistance climbing past 6,000 RPM. It's pretty crazy how it wants to run, regardless of gear. There is quite a bit more torque across the rev range, and I'm wondering just how much, along with how it'll go once I've got everything fixed and tuned. This is more due to RapidBike, but there's still no return of the dreaded closed-loop taper/surge behavior. Even though I haven't gone in to reset it or anything, it's adapted to the Delkevics pretty quickly. The "quieter baffle" in the Delkevics also brings down the sound level to just within tolerance for riding. At speed (above 55 or so) the sound disappears behind you so long as you are at cruising RPM. Sitting at idle or low speed it's still pretty loud but doesn't wear me out. What's really interesting is how cars react. They all know I'm there for sure now, and on Sunrise Highway they all either stayed pretty far back or used the next available turnout to let me pass :lol: I still coast in a bit to my driveway and try to get away from home as quickly as possible, but my neighbors tell me they have yet to hear the bike inside their houses. Bike still has some behavior that's attributable to old and dirty fueling, including difficulty starting/restarting sometimes. On my RapidBike auto map there are also a lot more maxed out values than in the other kids. So there are clearly more gains to go here, but the headers are crazy good so far.
