Super fast shipping. Installation was a breeze. Grom feels so much more alive. Sounds amazing too. Next is the big bore kit once they’re available.
my grom is not working now
Big difference in power makes the bike more fun to ride
Awesome little kit 79mph on the dash 14t 37t ( I know it's not right ). Little extra pull and sounds completely different. Can clutch up in 3rd gear. Easy install watch a couple of videos. Do not hesitate your only missing out on the fun.
Monkey feels like pops reached behind us and pulled the governor spring back on my old go-kart. Around 6K and up, Hold on son!
**Cams are in stock and shipping!
***If you already own a DCR or TB camshaft you can still purchase our Reflash for those mods here: https://www.dhmotoring.com/products/stage1reflash
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 TB 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!
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)
