2020 Honda Grom
I have one, tried to return it but they would not give me my money back. I installed it at the same time as my DHM piston and ported head so who knows if it helps or hurts performance. The reason I hated it is because I spent HOURS picking shavings off of it before I would even think of installing it. It is magnetic and ends up covered in metal dust and shavings. When it arrived it looked like they might have shook it real hard to knock some of the metal off before mailing it to me. That was clean enough, ship it.Thinking of going with a lightened flywheel while I'm at it.
Any thoughts on this?
