The Reason Why Your Motorized Bike Cylinder has Score marks!

- Hey guys welcome back to the channel as always! Today we take a look at my Yamaha's top end and I explain why your cylinder has been damaged. Spoiler alert it's because your not warming the bike up enough. These are cheap two stories motors that need time to warm up because otherwise it will do alot of damage inside the motor.
If you guys enjoyed the video it would be great if you could comment like and subscribe!
Thank you all for watching
I really really appreciate those kids who get out of there room and get familiar with these thing and do something different.... Rather then getting locked up in room and eating junk and play fornite
Your not wrong at all I totally agree. Most of the kids I know in grade 8 have no mechanical knowledge and you really need that when you get older so you don’t get scammed and you can do things yourself for 100’s of dollars cheaper.
Very cool looking bodywork on your bike. Love it bro. Also clear video, clean looks and great explanations.
Bro. You made great videos that I always enjoy and learn from. I look forward the next one. I’m just getting into the hobby and like seeing the possibilities.
Thanks man I’m glad you like the videos and when I was starting out 3 years ago I had no clue what I was doing. But from real experiences and watching UA-cam videos on how to repair my bikes I wanted to share that information to other people. Hence why I have this UA-cam channel.
The other day I was omw home from work when bike started acting fu NY. Evry so often it would kinda jerk like I was grabbing the brake for a split second and then letting go. Eventually it started making a racket and they whack it stopped. I could then rock it back and forth and it would free up. Meanwhile I got caught in a rain storm so while waiting I took the head off which looked fine, but piston had some pitting near a transfer port and a good nick in the tranfer port itself. And when I slid cyclender up alittle there was the dreaded silvery residue with little metal flakes. I'm almost certain what you were talking about with the piston expanding faster is exactly what happened. Not letting g it warm up enough first.
this unfortunately happens to often with these bikes the piston Expands to fast and your motor can even cold seize which is way worse and causes immediate piston damage. wear on iron cylinders are a big pain. I ran 32:1 very rich mixture and took it easy for the first three tanks. I cleaned the cylinder out and ported it to get rid of any metal flakes and rough edges. Even then my Harley still has two very tiny score marks and I followed every step to breaking it in. Sometimes it’s not your fault it’s plainly the motor.
@@keeganhache6667 for the forest 500km I ran the ridiculous 16:1 the manual said. And took it easy but the one thing I did not do was take the engine apart and check for things. By the time I started watching videos I already had the bike together so being lazy I never took it apart to check for loose burrs or incorrect pins. Must say all that was intimidating at first but now I go a few months under my belt I understand the importance. Lucky for me I have another engine to throw on my bike while I check the busted one. Hoping I can take cylinder off and shake whatever feel down in there out. I don't think I'm skilled enough to split the case just yet. But I guess what better way to learn than a broke engine you not scared on breaking. I like to ride but a mechanic I am not.
I love what you do!
Thanks!
Nice work 🚲💨💨 and info 💨💨💯
Thanks bro
cool info how why did my phantom come with a window piston and Reed valve and it's new?
Where did you get those fenders? They look so clean
Please some one tell me where I can get the frame covers like this .
Recently ported my cylinder just a tad bit, I have vertical score marks on my piston and the cylinder, I’m guessing when I ported I left some metal sticking out from the intake and exhaust however I opened it to check an my fingernail doesn’t seem to catch on anything from the holes
I have scoring marks on my head gasket, and no matter how hard I turn the head bolts, it doesn't seem to fully squish the head gasket to the engine block. It's a metal gasket, but I feel like it may be the issue. I just replaced the wiring on my bike, but if that doesn't fix it, idk what will
The 100cc yd100 is still about 1,6-1.75 Hp stock
that Black paint is Going to make the motor Run hotter .
No it’s not enough to make it over heat. You most likely saw la hovers video on the subject and that 20 degrees difference can be fixed with a high compression head which I later installed
Love you 🤟brother from india 🇮🇳
Wow that’s a ways away I’m in Nova Scotia which is in Canada 🇨🇦
The fzr metal stuff where can I get that please
The front fairing and the tank cover I got pre bent from a local metal fabricator. But I did all the other paint and vinyl work to them. They are not very hard to make. I did a video on how to make them if you want to check it out!
I see your flex exhaust,I just got one and put it on today,what do u think of urs?
It’s a good pipe for a bike that you just want a bit more low end power to climb up hills. It’s no Mz65 but it will look nice on builds like mine because it doesn’t cover the panels like my dirt bike style pipes do. It can be routed down below like I have it in the video but also down and up the seat stay like I have on my indien road-master bike. Way better than those cheap banana pipes.
I put it on my nel lusso,it seems to run ok
Sorry but I don't agree where you saying take the head off once or twice a year..i have had my bike or for four years day one runny at 40.1 mix never taken the head off once everything running good I have done about two-and-a-half thousand miles on it ..
It’s not that hard to do and you can always check of your cylinder lining is chipping off. Most other bike channels recommend that.
I've went thru 2 cylinders and pistons in only 7 hours of having the motor and there very deep cuts and I haven't been able to find out what's caused it
Wow man that’s very unfortunate but your bottom end must have had a lot of metal in it from the factory and you need to flush them out with gas so they don’t end up in the top end. Also prepping your rings can help. Sand the edges of them with 320 grit sand paper.
@@keeganhache6667 alright thanks the first time it happened 8 cleaned it out with gas and it happened again I'm going to do more prepping I guess
The original bt100 was about 2-2.5 Hp stock not 3 tho…
It’s the rated Hp for the motor. A lot of people go by the rated Hp and the iron bore advertisers that it makes 3hp but in reality it’s 2.
Not really a big deal to me because I modify my engines anyway
First time I see a braided steel exhaust lol
Theyre pretty common and cheap less than $20 on amazon
Yup there called a flex fit pipe and they increase airflow on these little motors by a lot.
My bike came w scratches brand new is there anyway to fix this or can i sand down the scratch its not catching on the ports its a line down.. but i dont wanna give up will the motor still run if i try to just oil n lube the rest up make the most of it? Or will it eventually blow up
Hey Keegan…did you happen to see what I did to mine on Facebook…my cousin helped me fix my muffler
Yeah it looks a lot better and I’m glad the bike is running good for y’a
@@keeganhache6667 it is running better yes…it’s actually running like a motorcycle lol I think that’s what it’s turning into lol plus I saw two police last night n they didn’t even do anything when I came by their squad cars but of course they were busy n I had lights on my bike lol
@@keeganhache6667 how often do you gotta change the tire on these motorized bikes cuz I just found out tonight that I will need to replace my back tire
@@Championlakers22 Oh yeah lol one time I flew by a cop with my muffler strait piped and I asked a guy I knew that was outside and said “did someone call on me why is there cops?” He responded with idk it’s not me, so I fired my motor up and took off like a bat out of hell
@@keeganhache6667 the cops really don’t do anything anymore about motorized bikes lol they are just like motorcycles lol
so, after 15 minutes, why does my aluminium piston have score marks?
If it’s a brand new motor than you must have not been taking it easy for breaking it in.
When breaking in a motor you need to keep it under 1/2 throttle and run 32:1 so the cylinder can be well oiled.
@@keeganhache6667 i actually do 16/1 mix for new engine, havn't ridden my motorized bikes in a few weeks now.
Dang why not bro?
