Wow is all I can say really great customer service and quick shipping and you can feel the increase in the power of the bike definitely recommend DHmotoring and the mod
You will not regret spending money on this kit. Tear down and install in under a day, started right up when put back together. Once the ecu learned more I took it on a speed test and hit 77 and still had a little more to gain.. I would recommend this to all my friends!!
Man I love the cam an felash an I just ordered a high compression piston to have a lil more fun
Fast Shipping and Easy Install
Super Noticeable Change in bike speed and REV Limit. Must do! For a basic Upgrade! They should’ve came like this from the Factory. Fell more into the bike after this upgrade.
UPDATE: After thinking I installed my cam incorrectly I took my bike in to a shop. Checked timing and valve adjustment and everything was OK. However, grom was still running like crap. Shop mechanic removed my DB intake filter and choked up the bike and it began running fine. Thinking the wrong flash may have been put on the ECU I sent out...
**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!
