I haven't had time to ride a lot. Short trips around the block. It seems to pull better all over. Keep in mind it is a 250. Idle had to be backed off. So far, so food. I just need to log some real miles.

Bruce-

How's the JD Tuner working out? Did whoever you got it from give you recommended settings? My Husky runs well but pretty hot in this weather and I think to address the fueling. I was planning on ordering a JD from RMATV or Mototaco (but I think Moto is out) and the other delete stuff but thought that I'd check with you first. Any advice?

John, I am running the same tuner on my 2020 500 but got it from a different vendor. All of these tuners (JD, BDSB and others like them) are re-branded Dobeck tuners. They work well. Easy install and simple to program. I went with the BDSB tuner only because he had dyno charts with nice AFR curves to back up his settings. I set the bike up per his recommendations and the bike runs flawless. Starts easy hot or cold. No flame outs and smooth as silk from idle up to top. I haven't touched it since I installed it. The KAT was a good test for the tuner. My bike ran a steady 170-175 degrees. The ambient temps were mid to high 90's with 60-90% humidity and the bike ran well. I have my temp displayed in the map screen on the Voyager Pro so I can see it at all times.My fan didn't come on that much, so I know the motor is happy. I am very happy with the performance and throttle response. I am sure any of these will work good, but they are only as good as the settings you put in them. I am happy to share what I got for recommendations from BDSB. He has settings for stock and modded configurations. I am running open end cap, vacuum evap plugged and added the dongle, removal of the intake airbox reeds and the smaller exhaust manifold.
Lots of cool bikes---

Yes. Runs well. Cooler. Was preset for “off road”. But is fully tune-able. Easy and has instructions. However, uncorking is necessary. Also easy to do.
