***Update 6-3-24, The Decha HR camshaft has been added as an option. It provides the same gains as a TB or DCR R2 but with a different lobe design that is not as noisy due to a larger base circle diameter.
****DOES NOT FIT THE 2022+ HONDA GROM/MONKEY, for the 2022-2024 model, click HERE
If your Grom already has an intake and exhaust, this is the next step!
We've created a camshaft package that allows you to add a Decha HR or TB Parts camshaft and our DHM Reflash to your bike. This will add as much as 2-3hp and will also increase your rev limit to 10,000 rpm, while also correcting the fuel and timing tables in your ecu. Your Grom will experience much stronger high RPM power, as well as the ability to pull to higher RPM before shifting. After tons of dyno and street testing, we feel this it the best bang for buck upgrade available!
Benefits: Corrected Air/Fuel ratio for your exact modifications Increased ignition timing for throttle response and HP 13+ HP depending on your intake and exhaust setup 10,000rpm rev limiter Normal cold start functions (no bad idle issues when cold)
***Each tune is catered to your exact modifications (intake, exhaust and cam brands, etc.) After checkout you will receive a link to an online form that will ask for your bike's exact setup so we can tune it accordingly.
You have two purchase options for delivery. Once you've completed the purchase, we will email you with instructions on sending your ECU in to be reflashed. You can also choose to purchase a core ecu, we will send you a flashed ecu and you can return your original one and receive a $50 credit or keep it as a back up.
After changing my ecu, vam and air intake the bike works fine until the motor is warm… it starts to bog and isn’t sparking right in higher rpms any thoughts or tips to how this may be?

Great package for my Honda Monkey
Bought this and it totally improved the performance of my bike. The bike accelerates faster and can hit a higher top speed. I recommend this to everyone who is looking for more speed without wanting to do a big bore kit.
