i spent all day watching the build vids so i could catch up and it was will worth it and the bike is coming to gather very nice
Thanks for watching :)

@photogromer can't wait to see the bike on the Smoky Mountain crawl
I think that crankshaft you refer to may be a connecting rod lol
Why didn’t you check the ring gap in the cylinder?
Can't wait to see how it's runs
its the little details that ensure the longevity of an engine. leaving those little pieces of gasket material from the original base gasket can cause premature leaks FYI. also if you coat the washers on the head bolts with a light coating of oil it will give you a more accurate torque yield to the head.
In the yamaha service manual they even recommend filling the head stud threads with oil before assembly for true torque to yield results
Usually the torque spec is for dry, if u lube and they didn’t specify it’ll come out too tight
The tech form Partzilla said to not apply to much oil on the cylinder wall because the rings need to cut into the hoaning of the cylinder.
ok listen to him, he probably knows more on the subject
@@Photogromer :D Nice one! Thanks for the answer! :D Very cool build! Love the channel!
It's starting to come together.
In Indonesia we have custom 125 cc engine into 250cc twin cylinder.
I been waiting for this a long time thank you!!!! 👍🏻
I love your group ride videos
YAY THX FOR THE AWSOME VIDEOS homeslice dawg
Engine exactly the as Honda Future 125 carburetor in Malaysia 🥰🥰🥰
Great video. I like the details! Just one question does the stock exaust would fit on the big bore kit or would it need mods? Thanks !!!
I like the dirt bike tricks😂🤣😂
you didn't talk about setting the width of the gap in the two top rings. maybe it was already done by the manufacturer... was that not specified in the instructions?
John David Dunson not that important but good practice
Why NOT GAB THE RINGS first in cylinder and then use feeler gages to check tolerance (you MAY need to gently file) using the proper rings rotating filer, now it’s just a question so don’t go hating on me I’m just curious. SCOOBS UK.
gap
They actually make piston ring pliers ($5) to install rings without risk of them breaking performing the method shown in this video
hi masters , im from Philippines is honda grom125 all engine parts is the same to XRM 125 FI engine?
Hindi nila kilala ang xrm 😂 wala kasi xrm doon 😅
hahahahhahaa, same engine ung honda grom sa XrmFi sa pinas, pero d pwd mag upgrade lg kaagad, nagpapalit sila nang ECU for new timing sa ignition coil tsaka sa feed nang injectors, nu bayan kita upgrade parang plug and play lg
Kaya nga 4v pero plug and play lng hahaha, parang malaking Qatar... Qatarantaduhan...😁😁😁😁😁😁
@@Shinenawa kaya mag upgrade nang ganyan pero need mu cguru mag benta nang kidney para dyan hahahahahaha
Photogromer what kind of crazy engine can you put in the Grom, can you do a 125cc 2 stroke in it, crazy moto!!!
Rocker arm😂😂😂 how about maybe a rod? And those wrist pin stoppers😂😂😂 how about circ clips?
Ring gap check ?
Just bought a 2023 grom any idea when Koso will come out with big bore for my year?

เดาเอา
What procedure did you use for break-in? Rpm limit? miles driven using precautions?
9:15 that looks rough. maybe use a plastic scraper instead of a metal razor
You only need one click on a torque wrench. When you click it twice you may possibly over torque it. Just helping you out for future reference bud. I know this vid is old just letting you know for future reference.
Click type torque wrenches typically under torque. Unless you're dealing with very tiny measurements, a second click is necessary to ensure you're as close to the specified torque as possible. Even then, your torque will still be off +/-4%.
AMAZING VIDEO!!
Just PLEASE fix the mic clipping issue... digital distortion sounds horrible...
I get too excited
Sorry I meant GAP flipping phone and my big fat fingers lol. SCOOBS UK.
How can i purchase koso head and ship it in philippines
Meron Yan dito sa pinas, 52k lahat set nya... Block set + head, meron din cla 162cc, 172cc at 182cc sa stock stroke...
Putin turned to Kim Jung, then back to Putin, then to Trump at the very end 😂
Between big bore and engine swap (like ZS190) what do you guys think it's better? What's the mpg and weight difference after this?
190 won't fit a grom frame
@@armdrop101 It will, you just have to cut a small part of the engine casing.
@@TheGamersRace 170s make 30+ hp more than enough for the grom.
@@armdrop101 Not when you're aiming for 50hp. The 190/212 just needs part of the mounting bracket on the engine casing shaved down in order to fit onto the grom frame. Same for if you want to put it on a ct70/ct90 frame.
@@TheGamersRace trans won't take 50 hp for long. Better off swapping it with 250 or 300.
Left me hanging lol
Eh?
Where I can buy the head and block from Philippines
Why don’t you degree the cam .
Don’t you need to change your timing chain with the 4v head? I also read that you need a stronger starter with a 4v head too. Just wondering since I’m about to buy this kit for my grom.
Will probably stick to the 170cc kit but keep stock head for now.
Tensioner not chain.
Wow
pharnith gaming bro ស្គាល់គាត់ដែរ
You forget to do a hell of a lot.
how much its cost the set head and bore?
top speed ?? and ecu and fuelpack ??
skipped showing inserting the wrist pin in... one of the most difficult steps...
Is it possible to paint the casing? What methods would work best?
Powder coating would be best
Amazon page mentions horsepower, yet doesn't give a number.
I’d say around 20-30hp. Depending on how aggressive of a tune. I’ve seen dyno results of 30+hp. I’d say ours was closer to 20ish with the conservative tune and rev limiter set. Plenty fast though.
Which camera do you use to take pics.
In your video
1 chopper vs 100 honda bikes
The one listed in the video description on that video
thanks bro
where can buy this set ?
this man is really spinning the engine backwards?!
The amount of nouns you guys get wrong lol
stock crankshaft on this 4v kit ... the engine is soon dead !
Koso recommends keeping it at 9800-10k RPMs. Should be fine if you don’t abuse it. We added extra support bearing for the crank shaft last week also. Plus we will be adding a proper tune to this build. Should be good for awhile however at some point we will add the bigger crank so we can really open it up.
buy kitaco crankshaft on webike it's not expensive and your engine can survive
he also needs a stronger chain for the valves because the stock will wear out real fast !
i heard 2000 miles with the stock valve chain if you go longer it will snap !
the koso kit is great but a kitaco neo kit has all the stronger parts you need .
monkey-tuning is it the big end rod bearing that fails? I’d sort of expect the small end to seize on the pin with just the little oiling hole
Is that bolt for tension the chain at 16:13?
yes well the rubber chain guide part
@@Photogromer mine is like that but i am planning to buy a bigger bore from naraku but the tension bolt is different its on top that's gone be a problem? What do think?
Hey guys I m looking for a engine too by
Can you sponsor me some of your used or 2nd hand parts. Im a motorcycle drag racer enthusiast. I will appreciate it even it is used motorcycle racing parts. 😁notice me pls.😀
No needle bearing?
Whatca talking about?
Photogromer crankshaft needle bearing
กุว่าล่ะ
It still 4 speed or 5 speed?
Omfg. Y’all missed some crucial steps.
It’s ok.

you still can't pronounce patron right lmao
Joshawa and you can’t spell it
