I’m amazed how perfect this guy is. I’ve never in in my life 😮seen anyone so precise & immaculate as this guy. Shame not many people are like him around in our days, you can see how dedicated he is, I would trust him with my bikes any day. I don’t even own a Grom but watched the entire thing as I’ve never seen someone break every down like this in such fine detail. He has OCD in a good way. Be interesting how much this upgrade costs to do

Thank you for making this video and explaining all the do’s and don’ts. You sir are a gifted engine builder!!!

[@motojo303]

Possibly the best detailed and professional video I've watched. What a pleasure to watch. Now I'm going to go buy me a Grom.

[@Mr11mrdk]

Continue: exhaust studs use silicone and nuts. Cylinder head, install cam, adjust valves on bench. Cylinder, install piston, rings and wrist pin and then install.

Been a month with my 2020 and for the life of me I can’t describe to people why it’s so much fun. Street legal pit bike is the closest I can get to doing so.

[@TheImtoomuch]

That's what I've said all along - Groms are like street legal pit bikes and I can't get enough of mine!

[@jal187]

TheImtoomuch my buddies all have them and I pushed it off for years now. Finally got to ride a fairly stock on and into the dealership I went. It was a blast stock and more fun as I mid and change things. Plus being from FL we have a ton of group rides and YT’ers.

[@timdisinger5694]

Hats off to you Sir ! Old School , thorough professionalism . Most if not all other channels , would do well to watch you & learn how to layout & execute a Video 😃

Secret of greater united state of America is his great teacher, technicians and hard work , thank you sir you are awesome.

[@wendyhicks8971]

Pre-ordered a Grom last week, which is due to be delivered June 21. I love this video. Lots plans for my new toy!!

[@PartzillaParts]

Good choice!

[@jssnsahahaha1831]

How do you like it?

[@wendyhicks8971]

@@jssnsahahaha1831 I absolutely love it! I would not consider the Grom a beginner bike, though. It's small size can make for some challenges when riding in traffic. It requires, in my opinion, a more experienced rider to be able to assess the 'personality' of traffic and predict potential problems. Despite that, the bike handles great, is super flickable, and can ride over just about any terrain.

[@tvd1188]

What a great video guide. Easy to follow, great videography and very concise. That Grom is going to be a ripper. Too bad it wasn't Dyno'd before and after. Lastly, after all those killer performance upgrades, the stock "vee" tires are left on.. thats the first thing i tossed after getting mine.. worthless rubber!

[@fasterdon]

You are a Master Craftsman my friend, I love your videos

[@charlesyates6687]

Great way to resist scratchin finishes is wrap in saran wrap or as some people call it cling wrap .

[@charlesyates6687]

I use a teflon strip to compress the rings like milk jug material and wrap the rings and use small baby visegrips tosqueeze the ends together compressing the rings then it slides easily iny the cylender and remove my tefflon strip and vicegrips .

[@reidspeed77]

Great vid! What was the fuel consumption once done? And 3 years down the line how was the reliability?

[@charlesyates6687]

Don't forget to drop the rear wheel drive gear to a smaller gear to use the increase in power to increase speed.

[@jolebole-yt]

Crazy amount of detail and work into this little Grom. Things can get pretty complicated quick :). Also the labor included to install all the mods cost more then the bike itself :). Is there a video of this actual bike running ?

[@Vuhjayjay68]

I bought a raptor 700r to rebuild so I went to partzilla to get some stuff for it and HOLY CRAP !!!!!!!! Who can afford these prices 10 bucks for a single bolt 😂😂😂😂😂😂 not to mention you get other oem parts for literally half the price they ask PARTZILLA IS A NO GO FOR ME

[@stevenknutzen4191]

Does this leave holes in the taillight housing where you remove the turn signals or is there a plug/ cover thanks

[@philipschrantz8402]

Very well done videos. I admire your attention to detail.

after all this we don't get to hear it run ? maybe even the first start ? that is SO disappointing.

[@seanmulvaney5607]

Thanks! I’ve seen and owned many Honda Grom style engines, yet I’m very surprised I haven’t seen them with the 170c cylinder and and did you say 4 valve head? The new Addition looks amazing, as if it should have always been made like thatS everything looks to be in correct proportion. And you can take a huge. I’ve recently purchased and nearly finished building a YCF, but I have a Daytona 190 Anima 5 speed with e start. And have a keihin 28 mm carb. However, I’d much rather have an EFI system. And though my engine has a 28mm manifold, they do make a 33mm manifold for a pwk carb some use with this engine. I’ve considered purchasing the grom 33mm EFI system to use with the engine I gave but I’m hoping to get some potential guidance from those who might know where our experience. I have not been able to find anything in any form in the pit bike companies that use a Daytona engine don’t have an EFI system done for it yet. I was also considering either the billitron, from lectron or the carb from yoshimera. Anyone with any words of advise. Experience or suggestions on the best route to take?

[@Mr11mrdk]

Make or buy a lead mallet. Easy on bolts and driving tools.

[@alexanderperez8167]

Great video and easy to follow

[@nazarleonov275]

what's the total for just the engine upgrade???

[@TheImtoomuch]

I started ordering from Partzilla because of Mr. Talley’s great KZbin videos, more specifically on the Grom and Raptor. I have never received a Partzilla sticker with my orders. How do I get one for my toolbox?

[@denniskupzog588]

perfekt, but why No start the engine? i will hear that machine 🥰

[@rgthomson100]

Was there a reason we did not see the centre bolt being tightened up, the one you removed with an air gun, all i saw you do was hand tighten it

[@byChecks]

After all these upgrades how much does the top speed change?

[@timgawlick4100]

have any kit come out for the Honda Trail CT125 ?

[@mattp9361]

I would like a price list of this video for my 2022 Grom. Just a one time package deal

[@jbean530]

Ten thousand dollars. Maybe twenty thousand. I spent one thousand just up grading the clutch, oil pump, clutch cover, pressure plate give or take a couple things. Buying extra tools adds up.

[@maxchalice5625]

I'm assuming that quite a bit of this stuff is interchangeable with the Honda monkey butt it would be pretty cool to see a video specific to the Honda monkey.

[@hedbngr18]

I know it isn't the point of this video, but I was honestly a little disappointed that they didn't do a before and after sound test from bone stock to post project. Nothing makes a person want to impulsively buy all these mods from Partzilla more than a nice post project rev session. Haha

I am so very confused! Why in the product display, and install portions show the Autotune module but when he goes to setup the Power Commanders the module has changed to the Wideband 2? Which one do I get?

[@clubdredd1337]

If you live in California Get the autotune! No tune required! If you DONT live in California get a wideband and have a tuner tune it.

[@not1au]

You would think Honda would've upgraded the Grom to at least a 150 by now.

[@jamesarneson7769]

What is the biggest big bore kit that can be added to a 2020 Honda Grom?

[@boingkster]

170 and 186cc kits are common. I would not bother with anything smaller than a 170. Some have found they have a hard time keeping the 180cc+ kits cool, even with oil coolers installed, and these kits tend to give the crank and rod a hard time as well. I would limit the engine to a 170cc kit, and make sure you install a high volume oil pump.

[@itzerisadomeeiot4980]

me like engjne swap a 250cc cbr or a 2t sonic engine made in thailand + fun 😂😂😂😂

[@Miwiz1]

so who bought the bike? or is it for sale??

We gave it away as part of a contest at the end of 2019. The Grom was a blast to work on and ride!
