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

[@andrewwilliamhorton789]

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

How are you going to show upgrades and mods with out a showing the bike running. Waste of 2hours, partzilla is one of them most expensive part store.

[@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 😃

[@huckwild6464]

or just go out and buy a Cb650r or 300r.......phahahhahaha

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

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

[@michaelhoots9659]

How much in total would be needed to do all these upgrades?

[@Ahrimas]

And just like that your grom costs as much as a real motorcycle! Jokes aside, cool video

[@jal187]

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.

[@altus199]

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

[@andrewmillard5326]

Why do you have to stick that monstrosity of an air box back on the bike. There must be a better idea out there like k&n filters.

[@stevenknutzen4191]

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

[@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.

[@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.

[@not1au]

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

[@nazarleonov275]

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

[@smr4712]

Love your videos, thank you so much!

[@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?

[@fasterdon]

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

[@toxin-snipezz8969]

Can you use the stock intake manifold ? I have everything besides the high flow fuel injector / throttle body / manifold Is it possible to use the 2014-2015 grom manifold & throttle body on a SF 2017?

[@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

[@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.

[@I-A-J_--]

Can you build my 2024 Grom

[@d1rtydropshotzz581]

hii guys , i was just wondering am i suppose to have oil in the alternator side of the engine on a msx 2018 ? the honda dealer ship said it was correct to have a bath of oil running around the magneto . is this correct please as im having problems with my bike dying down when revving it up

[@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!

[@turboimport95]

please tell me you dyno'd the stock and then the upgrades?? what was the power and difference??

[@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.

[@Vuhjayjay68]

The videos are great and this guy is very knowledgeable but the prices are horrible

[@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 .

Hey John, Where'd you get the handlebar clamp with the mounting spot for Koso? For the life ofme I can't find it anywhere

[@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 ?

[@sarahlivingstone8367]

Really enjoyed that - big fan of the Grom and now I know what's involved in a big bore kit and suspension mods .......... :D

[@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

[@rensduurland4153]

Can i do al the mods u guys did to you ‘18 Honda grom to an ‘20 Honda grom ??

[@SS61972]

Damn!

[@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?

[@trechavez7514]

Do you have to do the head on the big bore upgrade? Cause I can't seem to find it in stock

[@charlesyates6687]

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

[@charlesyates6687]

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

[@jbean530]

Who won the bike? Wish I would have known sooner.

[@easyfromtnbtw3555]

I taped off the end of the frame tubes so I couldn’t lose the bolts when taking them out

[@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.

[@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.

[@hengamzoletova8040]

how much was the total for everything?

[@spartanx169x]

Just the Clutch and bigbore kit was about $2,000. Only worth it, if you are a die hard fan of the bike.

[@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.

[@curtisburrell8122]

I’d just buy a bigger bike..

[@Miwiz1]

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