For the price I think I'll try this out, particularly since fuel economy seems to not be impacted.
If you'd said "under 3000K" I could understand - though I don't have much issue, but 5K? I'd look for the problem elsewhere.

I've mentioned it to the dealer a few times and aside from a pinched vent hose and a bad MAP sensor it's pretty much WAI. After the vent hose was fixed* (we never hooked the cannister back up) things improved a bit, and while it makes no sense adding the Termi slip on meant for the 821 has smoothed things out a shade. It's to the point that it is generally fine but not as smooth as the 821. I may go get a second opinion but I may also just try the RB and see how that goes.

Thanks for all the input. I pulled the trigger and purchased a Rapidbike Easy at a good price from a seller in Italy. Iíll post my impressions of it when I get it fitted and tested.

I can't exactly recall what setting it's on, but I have left it on the stock setting and it has worked out well. I have not noticed an increase in fuel consumption, still get 40-45mpg. Installation can be a little tricky in the back, so take your time since there's very little space to work with, the front cylinder is a snap. Let me know if I can answer any other questions.
Netaron, do you have any pics showing where you installed the module in the underseat area?

i have been using the rapidbike evo for a year or so. They (rapidbike) says the 821/939 ecu is very finicky. There is 1 expert at rapidbike that knows the 821/939 inside and out and will work with you one on one if you have issues. He even went so far as to go into my laptop remotely while plugged into the EVO module to tune my bike. It was a multi layer process where he did it 2 times as we collected data.

You may choose to install it differently, but the gray plastic box is the actual unit.

I fitted the Rapidbike Easy module to my Hyperstrada 821 today. It was a bit fiddly but I managed without removing any plastics or the fuel tank. The module itself fits nicely below the ECU. It took about 45 minutes and a bit of patience to thread the cables and connector plugs behind the rear cylinder. Will test it out once I have my new rear tyre fitted.

Glad you were able to install it without too much fuss. Keep an eye on your spark plugs (at least the horizontal cylinder) to see how she's running. I would check it now and check again after a couple hundred miles, and you can tune it accordingly.

Dimsport now advertisers a "UP/DOWN SHIFT ASSIST" module. Description reads like the original quick shifter with the addition of auto-blip down shifts. Module in the pictures looks much different than quick shifter, which had some basic adjusters for load and up or down. Anybody got any insight on this? Can't tell if it's meant to work in tandem with quick shifter or is simply an upgrade.

Did you have to adjust the trims from the +1 and +3 settings suggested as default?
