  1. Dhm break in

    Grom Builds
    I’m new to this but I just got first grom. I already have the chimera intake, tb cam, zoom loop exhaust and the DHM ecu installed. Is it normal for the bike to be boggy at first after installing the dhm while it figures everything out or did I do something wrong. The bike has only 25 miles...
  2. 50-50 Mild Street Build

    Grom Builds
    I've had a Honda CRF50 since about 2007 when pit bikes were still a big thing. Make Pit Bikes Great Again! I set my 50 up for mild street stunt - wheelies and stoppies. You can see my 50 here alongside my 2007 Buell XB12 Scg Lightning. I bought both bikes new and still own them. The Buell...

    I have a 2015, Twin Bros Exhaust and Chimera intake. I love the throttle response and power from 2 simple upgrades. I live in Utah, somewhat higher elevation. When I accelerate from a stop, while in 1st & 2nd gear, the bike seems to hesitate and does not accelerate very smooth, its like it...

  7. Questions about MNNTHBX exhaust, Chimera, and Bazzaz power output, and throwing code

    Grom Performance
    MNNTHBX Exhaust, Chimera Intake, Bazzaz ZFi, and 14t sprocket up front. I put the MNNTHBX map provided by them (is it okay for me to provide a copy of that here?). I'm 6'2" 225lb. It feels a little faster on the top end, but not great, and I got about 7mph additional top speed, so I'm topping...
  8. Running a Chimera or pod filter? I have a question about the noise.

    Grom Performance
    I've read plenty of people saying a pod-style air intake is much louder than the stock airbox but I still have some questions. 1. How much louder is it than an aftermarket exhaust? I know some pipes are louder than others and I have no idea what the actual db values may be but let's just...
