This is the first Honda Grom I have ever owned. I was trying to get the TB Big Bore kit thru DH, but it wasn’t in stock so I got it direct from TB. I dealt with Shannon over Email to get the appropriate flashed ECM. I told him everything that was being done and the parts that were being put on. He set me up with what I needed and had it shipped to my door in two days. Everything has been done to the bike and the ECM works perfect. I won’t hesitate to purchase from DH in the future and highly recommend them.
