The Honda Elite 80 is one of the best selling and most produced scooter in the United States. So it was only a matter of time before one showed up in our shop with a blown engine. This particular scooter had served its owners for well over 11,000 miles but a catastrophic engine failure landed it in our shop.
The first step was to check the baseline of the engine. A compression test confirmed something was seriously wrong. The Elite's engine was only producing about 15 psi of compression. Thats WAY under the 150-180 psi a healthy engine produces.
After removing the engine the valve train was inspected for a bent or burned valve. The cylinder head was then removed and we discovered the piston had a dramatic amount of movement inside the cylinder bore. After removing the cylinder we found that the piston had completely shattered!
A thorough inspection of the bottom end found that the crankshaft, crank bearings and connecting rod were still in good shape. So we fished out the piston pieces with a pair of chop sticks and proceeded to rebuild the top end.
The final speed bump was discovered when decarbonizing the head. The intake valve had been damaged on the sealing surface so a new valve had to be ordered and installed.
The first start of the rebuilt engine took place on a very cold (by texas standards) 32 degree day. After a few attempts with a pretty weak battery the engine roared back to life.

It great you can still get genuine replacement parts to this.
I loved the lapping valves trick too. 👌
Man it sure was harder than it used to be! The gaskets and piston were no problem but we had to go on a serious hunt to find a replacement cylinder!
Well China has a LOT of scooters that need repair so theres that ....
I have a 1995 ch80 and I know nothing about repairs but watching the videos gives me a little more confidence to try👍
Man, Garret.. I hope this is the new way your channel is going to… I’d gladly watch the HELL out of this…
Please keep it up…
Glad you like the new video style! We'll still be doing the scooter 911 tutorials but the majority of the videos will be similar to this one!
@@Scooter_911 That is wonderful. I loved it, honestly. I know one of these videos can take weeks or months (depending on parts). But, I really think if you can pump out a video per week, your channel will beat the algorithm and skyrocket. I wish you the best, bro...
Makes perfect sense to add a couple of chop sticks to the tool kits of all my Japanese bikes. Never thought of that before.
Yeah but don't make the same rookie mistake they made. They used Chinese chopsticks, and every good mechanic knows those are not compatible with Japanese engines. You should only use Japanese chopsticks on these Hondas or you risk blowing the whole damn thing up.
blew the rings on my 87 bought a motor off ebay but still wasnt confident bc of lack of videos thankyou for posting
Glad to see new content from you, hope everything is going well with you and the shop.
Love seeing a new vid from my man GS. Glad to see you're doing well and I enjoyed the teardown!
very nice work, Garret.
Good to see you back, good video 👍.
Thanks 👍 Good to be back!
Great content ! Thanks hope the biz is doing well !
Thank you very much! so far so good!
I sure wish you would do more videos, I enjoy them.
Excited for the Tao Tao update!
Always love a new video and love Honda scooters! Thanks.
More to come!
Well done!
Is the tao tao series coming back or not? Loved the video :)
Hahah I'll never escape that little bike. But yes it will make a come back soon!
Love the videos, glad to see you have a new shop! I learned a lot from watching them and been able to fix most issues with my scooter... I did run into trouble with a 150cc GY6 scooter that keeps getting hot after about 15mins running, I tried everything and the only thing that keeps it from running hot is to "run it" without the belt for testing. Could it be a bent rod? replaced lots of parts..lots.
nice to see your new videos and will fix the bikes and scooters in thebackground and post videos of doing that?
Unfortunately not every bike in the shop will get its turn in the youtube spotlight. But We're going to try to make videos on the cool and interesting bikes and projects as well as continue making tutorials.
This was a good watch!
Right before I get started spending my Saturday rebuilding a Honda Spree engine where the old owner decided to run it for a while with 4 stroke oil instead of 2 stroke oil... What a mess.
Oh dang! good luck! But since you're in there maybe its time for some performance parts...?
@@Scooter_911 you know it!
Two stroke oil is just straight 30 weight non detergent motor oil
Welcome back! Awesome content as usual. What happened to the taotao? I was enjoying that series
love the old Honda scooters!
style and pazaz for days!

So glad you posted a new video! It's a great one, too! Hey - what compression tester do you use for these small engines? I've been getting a lot of mixed messages online and want to be able to trust my numbers.
I use one I bought off the MAC tool truck. I've had it for years and it's served me well. I know Mac doesn't make it though, I think it's actually manufactured by OTC. I did, however, replace the lower hoses that thread in through the spark plug holes. They eventually gave out, but that's par for the course when you use a tool almost every day. The lower hoses are snap-on and they're much heavier duty than any other sets I've seen. If I had to recommend a kit though it would be the thread-in OTC kit. You can even use the adapters for a leak down tester.
@@Scooter_911 Thanks for the advice! I was leaning toward the OTC, but you've sealed the deal for me. Your new shop looks amazing. It's awesome to see you livin the dream! You're one of my favorite mechanics on CZcams and this video is a great example of why -- you show just enough of the nitty gritty and have a knack for explaining stuff so clearly. Also, that music! Love it!! Keep it up, man!
Why do you have to be on the other end of the continent ... I cant get a single Repair shop to fix my bikes, they will fix other small engine stuff but not a scooter . Ended up buying a used one, didnt want to as that cost me over 2k .. We dont have a repair shop like you have here, electric yes, gas Nope . Im now watching you and others to learn how to do it myself, i may be disabled and handicapped but ill sort it . Keep up the great videos Please... Spring is coming and ive got 2 bikes to fix and could use all the help i could get . Cheers mate .
good luck dude!
Great video👍🏻
Thanks 👍
Tao Tao sighting @ 11:21, it is still in one piece!
I think you should do another corolla project so we can here that catchy song again. 😊
Please more corolla content i really want to see how that efi carb went
we'll revisit the kairolla soon!
@@Scooter_911 that's good news! Tbh, I actually enjoy whatever content you make. Thanks for making your videos. 👍
Great your are putting out videos out again! But what the hell happened to that taotao 😆
It coming back...with a vengeance....
I have a 2017 zuma fx, I bought new. The valves aren't adjusted using feeler guage on my scooter. It's done ( I'm sure you know how its done) using little small caps. There Hydrologic, and you change out the little caps. Using a caliper and measuring to find out the right size to use. If you ever run across a scooter that needs it done, I would love to watch. GLS.
How much does a big repair like this cost? Very happy to see you succeeding man!!
You know it was pretty reasonable. Definitely less than purchasing another scooter!
@@Scooter_911 cmoon man that tells nothing
@@Scooter_911 we know its variable ... Roughly .. not exact. Cause a replacement, used, could run from 50 bux to 3000$ But my guess is under 500 ?
Put another way, how many hours did it take you to do this? It’s hard to guess. Could be 4, could be 40!
Lol you could buy another scooter for what I charge 200 a hour.
Great!
Awesome :)
very cool ❤️❤️
Thank you!
Awesome video. I have a 150cc Vespa and in the Vespa / Piaggio world one would simply use a 180cc Malossi kit to upgrade the cylinder head/piston instead of replacing with an OEM 150cc cylinder. Are similar cylinder upgrades not normally done on Honda scooter engines? I believe Malossi actually manufactures the OEM 150cc cylinder and piston for Piaggio.
Setting cam timing, saw index marks on top cam gear, mark on crank gear??TDC maybe?
Why don't rebore just wanna know.
Love your video.
Man there really aren't a lot of machine shops left that could bore a cylinder this small. We certainly called around and found a shop in Houston but then the added shipping ends up costing more than a new cylinder. We've been on the hunt for a good boring bar since!
Great vid! That motor looked like a vertical GY6 from the inside..
Is this the Honda motor that spawned such greats as TAO TAO. Hmmmm
Wish you had a TAO TAO to compare.. Wait a minute!?
TAO TAO UPDATE NOW BUCKO!!!! I remember.
Yooo Garrett hopefully I get a response but your the only person I could find that's in English and recent so I got a pcx 150 but had to build it back TOGETHER but for some reason the stater won't crank !!.... But I noticed there's an extra red plug but where the battery goes I believe it's called a dcl or cdl 4 wires red plug next to my my relay (black/ white, orange /white, light blue ,brown ,)
neat but since elite 80 are so common and ratty running ones could be found for 200 to 500 bucks I would have not bother . Buy a parts scooter , drop the engine and reinstall . About the same amount of cash or less . No chance of any metal not being found or screwing up the engine latter. Great video just not what I would do cash wise but also the elite 80 might be harder to find where the person lives So I understand why they might.
Was that black C shaped tool a specialty one for installing the valves?
yeaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa!!!!!! love the vids man! keep em coming and thanks for all you do.
Thanks! Will do!
Waiting for Kai rolla finale
its coming. Covid has made a lot of stuff weird but we have a big send off for it!
DO you have a parts list available? I have a ch80 with no compression, need to do the same rebuild.
Where did you source your parts??? some of it i can find on ebay and other websites, but was curious if you had a better place to look
We typically use partzilla but sometimes we have to put in a call to somebody who knows someone.
@@Scooter_911 Italian voice " you gotta have friends" 🤣
what oil are you using for break in period? i did read on internet to use mineral oil, is that correct?
Since we're only breaking in the piston and cylinder the break-in oil isn't as particular as if it was a fresh cam or fresh crank bearings. We're breaking this one in with Genuine 10w40 full synthetic. Its what we use on almost every scoot in the shop. Fabulous stuff. But to your point if this engine had a new cam and shim under bucket valve train or hydraulic lifters I would be using a mineral oil with an engine break-in additive.
@@Scooter_911 synthetic is garbage especially for diesels
I noticed u used OE parts. I have bought and used the China stuff. It seems to work ok. What r your thoughts on that for a Buddy 125?
when we work on Genuine scoots we always order the good stuff from PGO. It really is high quality stuff!
@@Scooter_911 Thank u for your reply!!
Where do you get parts for that thing I can't find them anywhere
Do you know any good repair shops in Houston that can do this that you recommend my Honda elite 80 is smoking too
Hey brother I got the same bike as that but red it's a beautiful garage kept has not been started in about 8-10 years he thought it only needed a carb clean that's why he parked it for all those years plus family to take care of. So I did all that and It still not starting I can feel the compression it's got spark and its getting gas . It's only has 2,282 miles on it I was checking out online they say you have to adjust the valve's every 2,000 miles is that true?
Yes absolutely. The valve adjustment is pretty straightforward on those bikes and once you own feeler gauges it's technically free for life. I would also encourage you to measure the compression. 100psi is a lot different than 160psi but you can feel them both
Goddamn these scoots grow up so fast *sniff*
*green day's good riddance cues up*
So many montana plates!

Yooooo how the taotao doin 😂❤
Hi! Can you help me, I have a scooter Conti ts125cs. At first it started with a clicking sound of a solinoid while starting it , I just taped the starter with a screwdriver and tried again it started... following day I try to start and it gave me dizzy noise like ZING!!ZING!! from the engine like it's failing to turn...I took out the starter tested it and it's working....did a research and usually it's a starter Bendix...so I opened from the Bell housing side but I didn't find that starter Bendix so I was about to go for the stator side but I saw a video on CZcams and I don't see it. Because I wanted to find it and try to lubricate it!.......I'm confused can you please help me!!!
Hey i have a longjia roma xs51 with a LJ139QMB MOTOR with a top speed of 25kmh do you know how to make i go 35 to 40kmh
I was wondering how many miles it had before it went ?
Almost 11,000. It seems to be about the limit for the top end on a CH80.
By the way G where did you learn all your knowledge i know it wasnt self taught
It actually was. I learned a lot trying to repair my friends and my own vehicles in my driveway with Chiltons manuals (in the dark days before the internet was useful). But I learned a ton just working in different shops. I love reading service manuals so i've absorbed quite a bit of it over the years!
what music did you use at 11:00 ? really pleasent to the ear
Thats actually a little piece I produced for background music. Thanks for the compliment my friend!
Hi Garret I sent you a message to get more details on the CH80. Thanks
Hello scooter 911 need help i ride my scooter in the snow cold weather.. heres what happen i went to start my scooter
My throttle was tight ? Idk why and then i start it up.then it starts the 50cc is stuck tryn to go by its self and also revn really loud back tires spinning twistn the throttle wont do anything for it to stop this only the killswitch will ? Its locked trying to go can you please help me
How many miles on the bike and what caused the failure? Hodas are supposed to run forever.
Many myths surround specific makes! :)
this one had nearly 12,000 miles. That seems to be about the limit on the CH80 top end. The elite 150 and 250 went waaaaaay farther before needed much engine work. But you also have to consider the hours that would be to go 12,000 miles if your top speed is around 40. Also consider if 40mph is top speed you're spending a lot of time at wide open throttle. just some food for thought.
Two strokes last longer than four strokes
@@catsbyondrepair kinda..... 2 strokes are simpler. But 4 strokes from Honda are extremely reliable. more bout power band and what you want from them.
🎉👏🏼👏🏼👏🏼👏🏼👏🏼
Where are you located I need some one like you to fix my scooter
We're in Austin Texas!
@@Scooter_911 can I ship my bike out to you I'm from Delaware I really need a great repair shop like yours
@@SG-wv7qu well that sure seems like quite the ordeal. What kind of bike is it?
@@Scooter_911 it's a 2013 ice bear zodiac 300cc trike scooter
@@Scooter_911 I need a total look over and radiator fan stop coming on but I checked it and it works fine but won't come on when scooter gets hot and now it won't start it just has a crank sound when trying to start it 😢
Where are you I want to bring mine to you for an exhaust lol
Nvm Austin Texas 😅
Scooters don't have to be registered in my state.
Why does my scooter keep bogging?
Wow! Thanks for showing me what my top-end looks like without all that ductwork all over it. I always wondered how my Elite 80 was getting air cooled. There’s no vents or holes in any of the plastic body panels. My Metropolitan 50 is water cooled. So I guess that little fan on the flywheel is sufficient enough to cool my little 80? Thanks for the video!
Hi Do you need some great lighting for your car to help you better driving at night? We're the pro auto lighting manufacturer for nearly 20 year and we're looking for sponsorship!
How many labor hours did you have in this project?
I think we billed 5 hours or so but I'm not sure what it actually took. Creating the video sure extends the time a job like this takes
@@Scooter_911 I have a 2014 Bintelli Havoc. I've been taking it to our local scooter/bike shop for engine repairs. Thanks to your videos, I've been able to do a lot of my own repairs. But now I really need your help. I was riding it here recently and while riding it, it started "hiccuping" (very slightly at first) but seemed to correct itself. Eventually, it slowed to about 2 mph and once I got off the throttle, it died. Now it won't start. It'll turn over but that's it. HELP ME!!!!
Hello why you not put more videos whit tao tao
Hello
Maybe you should check out Allen Millyard, He'd save it by tearing it down to bits, add a cylinder or two and make it run "Just Perfect"
Here's one where he made a v twin out of a couple of Hondas.
czcams.com/video/ckpYzp8Li3Y/video.html
We're all HUGE Allen Millyard fans in the shop. I'd love to try to do a v-twin out of a couple 50cc scooter engines.
This is really pretty sloppy procedurally.
I mean, what serious mechanic would even think about using Chinese chopsticks on a Japanese motor? You've got to use Japanese chopsticks if you expect the kind of precision results your customers are counting on.
It sounds bad though
