Grom is awake

Purchased stage 2 , cam and flash. Shipping was fast. I didn't adjust valves correctly, but once I did get proper valve clearances the difference is awesome. Definitely recommend.

Great tune!

This is the second one I purchased. Very happy with the power increase and ease of installation!

Billy Lewis
Awesome upgrade

Got my cam and ecu very quickly. When I finally got time to install it was awesome after my 20 or so mile break in ride. I'm 250 and can cruise at 55 sitting upright. Thanks so much

**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)
