S1 Cam Made My Grom Slower

I was excited about installing the S1 Cam on my 26 Honda Grom but I have been really disappointed. The bike feels much slower when accelerating and 5th gear is even worse. I even timed my 0-60 before the cam and then after the cam and just as i thought the bike was much slower. Installing the DHM stage 1 tune with my Yoshi pipe and Intake really woke up the bike but i do really regret installing the S1 Cam with the stage 2 tune. I had a master Tech at Honda perform the install and set the valve's so this poor performance is not due to a bad installation.

Stage 3 install.

Grom running good with the stage 3. Definitely more mid range with the HC piston.

S2 Cam and ECU flash upgrade

The ECU flash and Cam work great. It definitely helped with overall performance and top speed.
