- Here, I throw together some parts we have around the shop, to demonstrate the installation of a bore kit on a honda scooter. This theory/process will be 99% the same on all your 2 stroke scooters, vespa, piaggio chinese, honda piaggio etc. The key things to remember here are
DONT BEND YOUR C CLIPS
DONT FORCE YOUR CYLINDER OVER YOUR PISTON
USE PROPER SEALANT NOT RTV

No problem did you purchase the products here?
I’m so proud of you!
awwww shucks
Hello. I have a question that is seems like nobody asking this. I bought a 70cc 2t kit from dr racing. The problem is with the small end bearing. It has so much space to play between piston bosses. It is a 12x17x13 size,13mm wide bearing. It looks like about a 25% of is out of his space if i drag it to the left or right. Is this ok? Should i buy a wider bearing like 15mm? The bearing came with the crankshaft.
AWESOME! Thanks. Love the deer clip!
Glad you enjoyed it
Ok I just picked up a 87 elite se50 I believe dude said top end was done so it's seized I believe was going to buy a malossi top end 72cc what all would I need to run ? Or can I just change it out and it'll run after also need torque specs by any chance
hi i just ordered a 70cc kit from you for my zuma and all the goodies to go along with it, i was wondering would the s23 sealant you recommend on the website be good enough to use on one of these builds? thank you!
Do this kit can work on a yn50qt4 ? Is a 50cc 4 stroke ?
When you mention thread locker at the very end, are you referring to the blue or red thread locker?
U legend!! Shes not you're wife anymore! Shes mine pmsl. I love this channel!!
ha
Should you take a drimille and filled the casket where the holes are at so the rings dont catch?????
Can i use my stock carb and exhaust when I upgrade my cylinder to a 90cc short stroke? Af18 dio. Thank you
You can, but you wont get much power out.
why would you want to do that is the actual question, it could work but will likely not run
Hello guys! I want to ask if original is 50cm cilinder, but im putting aftermarket 70cm cilinder to scooter, what about exhaust mounting? Do original exhaust bolts wil fitt on bigger cilinder? Thanks for answer :)
You can
can i put in a 70cc kit and a 21mm carb on a stock 50cc crank? i already have a sport type exhaust.
need way more info then that call the shop and we can get you sorted
Do you coat the bottom gasket with the honda bond or just on the surface of the case?
I did
all mating surfaces with a very thin coating
Just put little greese coat
hey dude your video is just amazing. can i ask question. i have honda dio 2 af18e iam planing to upgrade block. can u give me advice 90cc or 70cc. tnx dude... iam edwin from manila philippines god bless
email the shop we can get you parts you need for your build
Yessss this is cool :) Perfect, Nice job keep going :)
thanks
I can't find the torque specs on genuine roughhouse.
Installed a Malossi 70cc bbk. Piston seems very sticky in cylinder when I manually turn the crank. I did pre-lube the cylinder. Rings did line up to notch before assembly. Do I need to hone a new cylinder? Piston seems too tight. Thoughts? The kit is a Malossi 70cc Cylinder Kit w/CDI for Aprilia Scarabeo Di-tech (3112054)
Hello, could you give me an update for this situation? How did you solve your problem?
what setup would you recommend that is good for long rides - af28 50cc
call the shop and talk to Paul he can get you the parts you need!
So where do you want the piston to be positioned when all said and done and ur about to start ? Tdc?
On a 4 stroke you have to make sure you set it at tdc. Two stroke it doesn’t matter as there’s no valves or timing chain
Was that a one-way tunnel or a tunnel design specifically for two wheel motor bikes?
This is for a scooter.
Put a rag under the piston when fitting the second clip because if it fall into the engine it can be a whole lot of trouble to get out
100%
I have a elite 50 im trying to put this kit do i have to machine the block or no ?
Don’t need any machine work
Does the crank have to be 45mm when installing 70cc? Or does that only apply to 80cc and up?
Longer rod doesn’t change the stroke or cc.
@@Scooterswapshop oh okay! I’ve just seen different shops selling 80cc + cylinder kits and recommending a 45mm crank rod instead of a 43mm etc. Does it really make any difference?
@@ToxicLion Sorry for answering 11 months later, but yeah it does indeed make a difference. When you have a longer rod on your crank it creates more compression during the stroke. This is obviously good for bigger cylinder kits.
Good video😃
Where did you buy the engine stand, it is where nice?
call the shop we can get you one
What kind of big bore can I use for my Honda aero 80 1983
There are none for your bike unfortunately
so I got a 2008 kymco super 8 50cc 2t... I bought a Naraku 70cc bore kit. it only came with the cylinder part with the exhaust port and the guy had to swap out the 10mm piston pin and piston with a 12mm piston pin and piston. it also came with gaskets and piston rings... I swapped it over and got the rings on and cylinder sleeve on and lubed it up and torqued down. I didn't get to upjet it yet cause improper thread size for the jet I bought to go with it.. and the exhaust won't fit due to the exhaust port is slighted so I have no exhaust on it. I crunk it up and let it warm up and then turned it off. I also got a aftermarket air intake too. it will crank and run but when I accelerate it hardly will move at all. can you tell me the areas I can work thru to get the issue fixed? please and thank you
Hi so it sounds like you purchased the wrong kit. I would purchase the kit made for your bike.
@@Scooterswapshop do you know of any kits for the 2008 kymco super 8 2t 50cc? Thank you
@@damienwhite9187 yes I would
Suggest doing a build invoice on our website and we can set you up with the right parts
how do you check squish gap i just put air seal kit50cc on and it melted straight away after taking barrel off i could see the melt and marks on piston and head where there touched harrd im going to take off oil pump as its the third head and about to put on a fourth
You would use soft solder near the outer rim of piston, turn engine over by hand so it compresses solder then measure. You can use a bit of grease to hold solder in place. You can also sneak in through the spark plug hole and feel the edge of cylinder and do it that way. I realize this is months old but perhaps someone else will have same question.
Jim CCC when having a bike with a 70cc bore and a sports exhaust will I need a bigger carb as it runs but will not Rev up
@@Tizzypj , honestly my experience with these scooters is quite limited, I recently picked up a 2009 Ditech that had seized and I’m making it a 70. My actual experience is 250cc 2 stroke Grand Prix motorcycles. Have you increased the jet sizes in your current carb? I know they do need more fuel-bigger mouth to feed and all. Racing planet has a section on their website you can ask questions and they have been very responsive. Where did you buy your kit? You should pay close attention to your spark plug and how it looks to determine if it’s too lean, bad things will happen if you run it that way. Perhaps find a good video on two stroke spark plug reading and then do a proper wide open plug chop and reading and jet from there. Hope that gives you a direction. Best of luck.
looks like they helped you out
Would this be the same thing for a 1978 Honda express ?
no
why didnt i found your channel earlier 😂
Hope you subscribed.
If I upgraded a 50cc 2 stroke to a 70cc would I need a new carb?
yes
Yes. Plus you'll need to declare it on insurance. If you dont. Your insurance will bs void. Plus you will get fined
Hey do you need to set timing on a 2 stroke
That's a loaded question all depends on what setup and does your ignition have a key way. But if you think you have to time it you likely have to time it.
What's your opinion on right stuff? And no either 2t oil(what I been doping) or engine assembly lube on piston, cylinder, Small end cage bearing, or oil in crankcase? Or was this just a demo for the guys that need to sing lefty loosey song? Jw as you guys aren't the standard TH-cam University. You actually know. Thanks!
lube everything metal to metal
How can i check, if the piston rings are in right position?
we explain in this and a few other videos.
Can a bore up engine last for a long ride or nah?
Thousands and thousands of miles. If it’s set up right.
What type of carb would I use for a Chinese 100cc bbk
Yamaha jog
we don't work on any china scooters here any more sorry.
How tight do you have to screw in the studs on the base
which ones
@@Scooterswapshop the cylinder studs
is there an upgrde kit for 2003 honda metro
You can’t make the displacement larger without machine work on the ruckus and met
can you use the 50cc head with the 100cc piston?
not sure exactly what your asking be specific
of course not
Hello sir can you please help me what is the best big bore kit for my benelli quattronove 49x I really want to upgrade my scooter thank you in advance
Anything for 2013 pcx150
plenty get on our site or call during business hours
Can I do this to a stock spree
I wouldn't suggest it on a single speed
I replaces piston, piston rings and cylinder, big bore, but now my scooter wont start
I would contact the shop You got all your parts from and verify they’re correct and ask about diagnoses, break in procedure and tuning your new parts.
how to order the Malossi kit
from scooterswapshop.com
Is that a stock crank ?
this video is so old ill watch and check.
On a weekly average, how many spam calls does your shop receive?
Oh boy. Per week I bet 50 at least it’s insane
you didnt set ring gap ?
You don’t need to on these kits. Taiwan or
China yes
Tao tao 50cc to 80 started up yesterday now won’t stArt
That's a bummer sounds like it could be 40 different things. probably a carb issue.
it will damage the part of the scooty
what will damage?
Scooterswapshop, I bought a big bore kit and super need your help. I think I might've screwed up installing it...
Ok, so you know the head, the one that holds the Camshaft and little hammers? Ok, so that head unit is held on with two long bolts right? Well, I think I might have over-tightened them because it’s not air-tight ): I can see a slit of an opening because it was too tight on one side.
Is this normal? Should I replace the gasket or put an extra one in there? Please help!
Here is a picture I took to help reference what I'm talking about:

Please help!!
Hi, I can’t really do diagnostics on TH-cam and I have no way of knowing what bike and products your using I would reach out the company you got the parts from for some tech support
You never showed how you fixed the rings
The rings are already fixed to the Piston. You could have shown how to fix the rings to the piston
slide them on
I wish the video came with removing the engine and putting it back on. All the portions riding fast and talking about sandwiches is fluff and doesn’t add to the core of the video. That said I did get some education on the subject.
Are you here just to complain on videos? Confused as to why there's 2 videos that you just complain on nothing positive. MAYBE JUST MAYBE, ask questions? And have a better look at things others do for free to help? Maybe say hey can you guys do a video on this.... Instead you are complaining about our "fluff"and free content. So just maybe this isn't the channel to watch? As we put "FLUFF" in every video for comedic relief. We love what we do, we do it for fun and to help people. But no need to help people that have poor attitudes. Next time before you make a comment stop breathe and think, then type. I'm sure your just going thru some stuff in life as we all are, we hope you get thru it and come back next time with a better mindset! Have a great week!
70cc is slow AF
Yeah its 70cc... what do you expect lol 1000cc?
