DHM High Compression Stock Bore Piston for Honda Grom/Monkey | FULL INSTALL AND TIPS!

MORE POWAH BABY! There's a lot to know about this one, and - I. COVER. EVERYTHING in this video!

Sorry about running mid-roll ad's on this. I know they're a pain, but this video was a monster to create and edit (surely as you can tell from it being 30+ minutes long). Hopefully it serves as an instruction manual for you and you understand my choice to monetize it based on the effort it took me. Thanks!!

What we have is a very special product from DH Motoring. This is a stock bore sized, high-compression (13:1) piston for the Honda Grom/Monkey 125. Stock bore is desirable because it won't heat up like a big bore, and won't require an oil cooler. It's also desirable because you can use your stock cylinder, which makes it super affordable. High-compression is desirable because it makes POWER!

I won't go into detail on the kit as I did that in my What's on the Bench? video about it here:

This install video covers everything except the removal of your stock airbox because I don't have that on my bike, and didn't need to remove my MNNTHBX Mtake to do this job. I also didn't highlight the factory manual procedure because I felt it was requiring you to remove too much, and found my own shortcuts around having to remove the throttle body, which would've been a pain. You might notice in the video that I don't show myself placing the ring gaps 120 degrees apart because the camera angle was a bit bad or difficult to show. Just remember to ensure the gaps are not lined up with each other, and a good rule of thumb is to space all 4 gaps out evenly and I really don't think it matters where on the piston they are, but I show the diagram from the manual anyways.
