    Competition Werkes GP Exhaust $250

    Do you know what fitment issues might occur trying to install this on a 2017 RC390? Anything a guy with a saw and a TiG couldn't handle? I loved the underbelly exhaust on the '15 and '16, it would be awesome to make one work for my '17!

    Rough idle and engine code after valve adjustment

    Thanks for that info! I'll be getting into it this week, and if I can't figure it out it'll go to the mechanic. Either way, I'll post an update.

    Rough idle and engine code after valve adjustment

    There is no fault code my Elm327 or Fixd OBD2 modules can read. Apparently, I unintentionally worship at cult of Steve Jobs so I'm using 'Car Scanner' for iOs instead of Torque. It reads what appears to be all of the data streams for this bike but no fault codes, stored or otherwise. Not sure...

    Rough idle and engine code after valve adjustment

    I just got my bike back from the dealership service center after having the valves adjusted. It started and ran fine for a mile or so at city speeds, and then for about 30 minutes at highway speed. When I exited and stopped at a light, I was idling so rough that it rattled my vision. After that...

    690 Wheels on RC390

    I hate to revive a dead thread, but you seem to know many things I do not! From what I've read about the stock RC8R fork, it seems like they're specced just about right for fitment on a 2017 RC390 carrying a 235lb driver. If I used the corresponding Brembo caliper and custom bushings for the...

    WTB: The brass bolt with embedded magnet that attaches to the kickstand and activates the sidestand sensor.

    I was adding a washer between the stand and the bolt so that the magnet would rest more firmly onto the sensor body, and I completely spaced that the bolt was brass and sheared it off. If any racers have removed your kickstand, or others who have bypassed the side-stand sensor, could let go of...

    Need Help Does a cat-delete midpipe require a new ECU and remap? If so, are there any that do not?

    Hello, just what the title says. I have a 2017 and I want to upgrade my suspension. Apparently, the Yamaha R-series rear shock absorbers that are compatible don't fit 2017+ RC390s without deleting the cat. I'm pretty darned ok with the bike's performance on the street and highway, so I really...
