2022 Honda Grom High Compression Piston Install!

I finally got around to installing my DHM high compression piston... this was a learning experience for me. I feel more comfortable now that I have torn the top of the motor down and replaced the piston. If you have any questions about the install please leave a comment below. Thanks for watching!

Who else has a high compression piston?

[@trailovingchevy2126]

I have the high compression kit only I haven’t installed it yet. Trying to get the rest of the stuff I want to put inside the motor while I have it apart. I have the same yellow grom but I put the yellow Camo decals on it

[@trailovingchevy2126]

Also keep up the videos. Want to see what you have in store for your grom

[@coltmeyer4590]

I've seen other videos of people blowing their motor because they didn't have an oil cooler

[@egoboost9952]

Nice video bro. I’ve been waiting for someone with a 2022 to install the piston. I’ve been contemplating installing mine but I keep procrastinating lmao. Definitely made it look easy man 🤙

[@TTorres1183]

You got this man. I have zero small engine experience and we made it happen!

[@Image-X]

Top of old piston looks completely normal and natural. That’s what happens when thousands of explosions happen next to it on each ride. 👍

[@TTorres1183]

I figured so… first time I have ever removed a piston on a small bore bike!

[@stevenm5769]

Just a heads up last year was my first year in Tennessee and it rained a lot. I have the same intake as you and I would recommend getting the k and n rain guard/protector. Rained so hard it started to bog down

[@TTorres1183]

Good advice!

[@aeror115]

Good and interesting buddy

[@TTorres1183]

I need it to warm up a little more and I’ll review the HCP

[@anhbillying]

You should use a compression ratio measuring tool... example a burette tube, too high compression ratio may be damage your engine

[@chasethelen4577]

Definitely on my to do list on the 2022 I just bought! How’s it running now that’s it been a few days

[@TTorres1183]

Like a champ! Can’t wait for warmer weather

[@1ming1]

What was the compression after the fit?

[@ABadCheetah]

Be sure to run higher octane with that increased compression

[@TTorres1183]

93 all day

[@jonathancastillo4856]

Good video man, one question, how long did yours take to get to you?

[@TTorres1183]

At the time they were in stock. So quick

[@jonathancastillo4856]

Only the silver and black ring a filed,correct? Or all the rings

[@azt6855]

We need more type r content. :( we miss it

[@TTorres1183]

What do you wanna see on the Typer-R?

[@azt6855]

@@TTorres1183 some meets, some runs with other civics, collabs with other fk8 and fk7.

[@TTorres1183]

Ok, I’ll what I can do.

[@Sparky_D]

For the record it's called a gudgeon pin.

[@bankfishingislife5484]

so i have a grom. it died a bit ago. one day i was riding it to lake at a random light its lost almost all power and could only putter. and it was puffing white smoke. its been at least a year. i didnt really have money to take it to shop then and i had to move and all this crap but someone at my new job said it sounds like the head gasket.. i havent worked on a engine in a long time but could it be that simple? i was thinking maybe the rings. i rode it daily for 4 years and put like 28k or so miles on it before it happened. what do you think you seem to know more about motors. the bad thing i live in the middle of nowhere in kentucky now. when before i would just take it to my friends dirtbike shop in california for random work. but i dont even see any types of shops like that here in ky. especially anywhere close to where i live lol. i would love to slap a 250 or 300 in it but then it just gets more expensive. i just want it running again really. for now. any ideas. thanks man. later

[@TTorres1183]

I would copy this comment and throw is on a grom FB page and have them tell you what they think it is. Sounds like something minor…

[@lorrbrad]

So I wanted to know if you have ran into that engine issue everyone is having if so how did you fix it I’m interested in buying the 22 but scared of that

[@TTorres1183]

What engine issue?

[@91rickstar]

I own a 22 have had no problems with it what do ever it has now got 420kms on it I personally know someone who owns a 22 grom aswell and they have about 500kms and they haven’t had any issues What issue are you talking about because I’ve come across none

[@ohshitnotanotherknob]

The transmission screaming issue?

[@lorrbrad]

@@TTorres1183 the screaming issue

[@TTorres1183]

I do not have one

[@888jackflash]

ONE YEAR LATER - How's that mod been working out? Reliable? Have you made adjustments/changes?

[@TTorres1183]

I upgraded to the DHM 149 kit and love it!

[@888jackflash]

@@TTorres1183 Very cool. I thought the 22-23 models could not be bored, due to changes in the stud placement (?). What other mods have you made to keep the motor "safe" - oil cooler/reflash/cam chain wheel... Hard for a Newbie to sort this stuff out! Thanks

Hey bro question did you have any bogging issues at lower rpm ?

[@TTorres1183]

Ehh maybe some but doesn’t happen anymore

@@TTorres1183 okay gotcha, just didn’t the high comp piston & cam On my 22 fired right up just has a slight bogg on take off

[@TTorres1183]

Big that piston some break in miles.

[@barryallen5507]

@@dailyridersie5024 Wouldn't you need a tune after this? Or am I being silly

[@dailyridersie5024]

@@barryallen5507 definitely need a tune I use aracer so I leave it n auto tune so far bikes running great only issues I’ve had so far is cold starts gotta give it litte extra gas but once it warms up she’s a beast lol 😆

[@davemorris6747]

How did you get the rings compressed back in the barrel. I’ve got to strip down my quad and wondered if I’m going to need a piston ring compressor

[@TTorres1183]

You mean back in the cylinder wall?

[@petev.9357]

No honing of the cylinder??

[@TTorres1183]

Nope

[@petev.9357]

New rings, cylinder gets honed. It's a given. How are the rings going to break-in? Your leaving compression and power on the table.

Lash is wrong ex.4 intake. 3 on tb cam
