I see a step i would reverse the order on. Loosen the cam bolt before you loosen the chain tensioner. It could slip a tooth when loosening the cam bolt. And cause you to put it back together out of time. Altho you should check it when putting it back together anyway.
Great video. Time wise and ‘too much detail to not enough detail’ was perfect (for me anyways. 2 questions; Is that a Leatherman watch band? If so, how do you like it? Also, what kind of ratchet was she using? A 7 tooth ‘chrome vanadium’ from McDonalds? Damn, that was hard to listen to! 😂
I'm going with the takigawa 143cc and cam. Would the installation pretty much be the same? Thanks guys.. Hopefully placing my order with you guys this weekend.
can you just install this big bore kit without a PCV or WBC2 and stuff like that? and i also wonder does this kit makes the bikes sound different from a stock Grom? and can you fit an aftermarket exhaust after you install the big bore kit
We have 181-183cc BBK for 3 years now on all our GROMS....... no reinforced connecting rod. All good. BUT........ It is a good idea to install one for long term.
This is a very helpful video, but If anyone is thinking about doing this, no matter what engine work you are doing on any vehicle, you should never use paper towels or anything like that, the fibers can get into the motor and screw everything up for you.
if i get the 143 or 181 kit, do i have to send you guys the wideband 2 to lower the fuel ratio? i don't have the pod-300. or does the new map for the bbk take care of it? thanks
@@HardRacingPerformanc , Respectfully, you videos appear to be upscaled to 720p. Given the way that youtube's streams them, we shouldn't see jaggies in them; only blurriness.
It's almost like Lego. This makes me want to get a drivers license for motorcycle, buy this motorcycle and mod the sxxt out of this interesting motorcycle!
+cory lepire brand new with just intake mod... it hit 73 mph in 4th gear at redline. with the smaller front sprocket on.. I hit 71 mph top speed.. but gained take off speed. I weighed 145ish at the time. now I weigh 165ish so it may be a little different now.
Shit, I want to get my wife a grom as a starter bike. Hopefully once she's ready to move up my big ass can mod the shit out of it for myself lol 6'4'' 280 pound man on that bike would look funny as hell but man it would be fun.
KIT ARRIVED IN HAWAII 2 DAYS LATER!! SUPER FAST AND VERY AMAZED, even with the virus still came super early... thanks
That's great news. So glad to hear that. Thank you for posting up.
So after watching all of the video, you guys did a AWESOME job!!!! Very impressed even with all of the cuts. You guys ROCKED that video.
Thanks. We greatly appreciate that. ;-)
Could you guys also make a video tutorial how to install the kit with the new camshaft? Would be awesome!
Michael Gebhardt
We do actually,............ it's on our Finbro Install Video PART 3.
+HardRacing What's more reliable, this or the Finbro?
instead of using a oil cooler i think i would install a oil filter. but question???? i thought going that big of bore you had to change the rod also
Do you have a video like this, but for the Z125 PRO?? Thank you for these videos BTW!!!
Unfortunately, we didn't get to make a video for a BBK for the Z125 yet.
are all horizontal motors the same in terms of big bore kits? if I got a lifan motor and just got a 180cc big bore, would it work?
I see a step i would reverse the order on.
Loosen the cam bolt before you loosen the chain tensioner. It could slip a tooth when loosening the cam bolt. And cause you to put it back together out of time. Altho you should check it when putting it back together anyway.
I would like to know if i buy the Takegawa 143cc bbk. What other part do i need to replace together ie. Clutch cover or oil cooler or etc.?
Great video. Time wise and ‘too much detail to not enough detail’ was perfect (for me anyways.
2 questions;
Is that a Leatherman watch band? If so, how do you like it?
Also, what kind of ratchet was she using? A 7 tooth ‘chrome vanadium’ from McDonalds? Damn, that was hard to listen to! 😂
yrah whats up with watch band.. can we get some info on uit..
Hello hard racing, how's the kit holding up???
I'm going with the takigawa 143cc and cam. Would the installation pretty much be the same? Thanks guys.. Hopefully placing my order with you guys this weekend.
What kind of ratchet is that? Does it have torque settings?
can u get a big bore kit installed by a mechanic
No reason you can't.
You'd just want to make sure the mechanic knows what he's doing.
thx for the help
Anytime.
Always here to help.
can you just install this big bore kit without a PCV or WBC2 and stuff like that? and i also wonder does this kit makes the bikes sound different from a stock Grom? and can you fit an aftermarket exhaust after you install the big bore kit
+FunwithNick
You can. But, your BBK won't last long.
Check out the entire video as well as PART 2 and it will explain everything.
How big is the new piston? Seems like the engine is the same as wave/nice/xrm 125.
Did you also bore out the case to fit the kit?
Hello, it's the manual instruction for installation come in ENGLISH?
Hello HR! Is that bore up kit use with stock cylinder head and throttle body? (No working ported anything). Thanks HR!
Yes that is correct.
Hi, whit this 181 kit you must install the reinforced connecting rod....or not?
We have 181-183cc BBK for 3 years now on all our GROMS....... no reinforced connecting rod. All good.
BUT........ It is a good idea to install one for long term.
@@HardRacingPerformanc ok thanks...how many horse power have now with this kit? do you have large throttle body installed on bike?
about 21-22 hp. Yes, Larger TB for sure.
@@HardRacingPerformanc and for the Ecu tuning what did you use? thanks
PCV & WBC2 we have many videos discussing in detail.
This is a very helpful video, but If anyone is thinking about doing this, no matter what engine work you are doing on any vehicle, you should never use paper towels or anything like that, the fibers can get into the motor and screw everything up for you.
mike kramer and replace the piston rod. Lol blue paper towels do a good job on not shedding. Never store bought kind
what mm bore is the kit cylinder ????
63mm
so the head stud bolts are reusable?
That is correct.
did you have to retune the bike after the big bore kit
It is recommeded to remap your Fuel Injection.
We have maps already made for PCV and WBC2.
.
ok thanks for reply and love the bike
HardRacing What device do you recommend to hook up and transfer the software
***** Not sure what you mean ? "device to transfer software" ?
if i get the 143 or 181 kit, do i have to send you guys the wideband 2 to lower the fuel ratio? i don't have the pod-300. or does the new map for the bbk take care of it? thanks
what headlight setup is that??
LED Double Row : ruclips.net/video/XY0-7dhkklc/видео.html
Dont you have to upgrade the oil pump
It's definitely, recommended to upgrade to the Super Oil Pump.
For doing intricate engine work, we need a little more video resolution.
LOL... if 720p is not enough, time to get some glasses. ;-)
@@HardRacingPerformanc , Respectfully, you videos appear to be upscaled to 720p. Given the way that youtube's streams them, we shouldn't see jaggies in them; only blurriness.
We definitely, record at 720p. Sometimes at 1080p if needed.
where do you sell the Honda Groм at
Not sure what you mean ?
Do you sell Honda Grom
It's almost like Lego. This makes me want to get a drivers license for motorcycle, buy this motorcycle and mod the sxxt out of this interesting motorcycle!
+Charlie Jones
It's hard to explain, but little bike is addicting. Even though we also have a 200hp, BMW S1000RR, sitting right next to it.
+HardRacing I had a 200 whp Beamer too :0
Sorry last Q, Whats mpg after mod? thanks.
Stock was apprx. 95-100 mpg ... after mod was approx. 80-85 mpg
HardRacing is it still reliable?
Apex Coup'detat : Yes. Very reliable.
Top speed?? Is it 72mph in your other video? Thanks
Just got back from FULL Throttle Test run, and hit 75.3 mph
16t Front Spocket

Cool watch :)
I want the 235 engine myself. You don't see a lot about that.
Unfortunately, we no longer offer the 235 motor.
Shit, I want to get my wife a grom as a starter bike. Hopefully once she's ready to move up my big ass can mod the shit out of it for myself lol 6'4'' 280 pound man on that bike would look funny as hell but man it would be fun.
Trust us. Everyone loves the Grom.
Wherever you go, everyone wants to know more about it.
How much does it cost?

sound more like gunshots if you ask me
Who sells a product without even translating the god damn instructions? LOL
only noobs like you need instructions like that.
Matbee If youre installing a big bore you shpuld jave the factory service manual and know what youre doing
How much more difficult is it to install the 4-valve superhead BBK?
