I have been searching for days for you guys, not knowing it ,you watch the channels and they talk about tearing down engines every race , maintenance over n over , and engines $$$$ this is what I was looking for , I’m in search of a home track to cut my teeth on . And I would love to find good people like you in our area. . I’m in New Jersey and no Motorsport allowed except 200 miles away ...Millville I’m a newbie to karts and it’s been daunting , I don’t have 10,000 I have mor like 1500$ and that took me along time to save , knowing that I could get a quality engine make some feel great ..and gave me hope again to get the back rolling , and trust me I will be buying my first engine Without a single doubt . I’ll be on the website after this .......thank you for this video
I just bought a used cart with this engine for my son. How do I tell what carb it has. Also, the threads on the crank shaft where the starter nut thread on is stripped. What’s the best way to repair this. I started filing the threads but as I get closer to the end the metal is pretty mashed. Can I get away with cutting the end off to the clean threads?
I like how this company does business very good @ what they do even though i am in Lynn, MA they deff get my business because of their well displayed product line.....my self and my buddy edward Bajo ha guagua get down with the karting to the core!!!!!!!
i own a kt100 kart but idk if they are supposed to be really loud or if the engine is just accelerated i would say but pushing down the brakes does not stop the wheels from moving
@Dartgame 340 lol. Not a troll question. All 2 strokes that i've worked on have a wet clutch and gears in the bottom crank case. Like the rm85- rm250, yz85-yz250, cr85- cr250, and kx85-kx250. They all carry one quart of motor oil in the crank case to lube up clutch disk, gears, and crank..
does anyone know what the best gear ratio set up for yamaha 100s motor is? I am new to Karting and just purchased a senior Arrow AX9 go kart frame with 11×7.10-5 rear racing tires on a 50mm rear axel I am purchasing the yamaha 100s motor next week, though not sure what gear set up to use, I want good take of speed and best max speed I could get out of for performance. I weigh around 98kg
That gear ratio will change from track to track & whether your running road courses or dirt & asphalt tracks also tire size. . Best to ask the leaders in your class for a reference & your engine builder as well . The rest will come from your practice time & record keeping. I ran Enduros with WKA & Woodbridge Kart Club at Summit Point for 15 years so there are many factors as what gear ratio to run at what track your at. There is no one set ratio.
It is best to ask around the track paddock what people are using some don't want you to know some will tell you I run 10:86 ratio on my kt100 but my track i drive at has a long straight so I go big on the rear sprocket

Hey Mark looking good in your older days. glad you are still showing the world how great those engines are. Matt Domenic
Lord have mercy, I was buying RLV's pipe of the week back in the early 90's LOL and yes Mr. Harrison at Comet was my engine builder
Most popular racing engine in Japan is KT100cc. Tends to get a bit sluggish on hot racing days after especially on the turns. Any way around this?
I started lay down road racing with these engines I ran light and heavy classes at each event .
that hilti drill, probably cost more than 2 of the engines combined
Looking for advice. How do I set the gap on my kt100 between pickup coil and flywheel and what to set it at

They are just stupid loud
Super Sport!!! Best kart racing I ever did back in the day.
I have a kt100 as well and it works perfectly, but when I put it on the floor it stops running and it doesn't starts rolling.
Does anybody know why?
Adjust your clutch or idle
Do these motors use oil for the crank case? I don't see a drain plug at the bottom.

I heard recently the engine will no longer be in production.
How many hours exactly?
Do you know where I could get a kt100 starter nut that goes on in front of the clutch
Do you guys still you the kt100 J motor in America?
Buenas noches don Miller una consulta ese motor de puede instalar en una bicicleta
Can the kart work without the can? I’m thinking about taking it off
One fell off at my club and it still ran. It’s already stupid loud dude
@@Gaven.degenhardt.racing I can imagine lol it’s already loud as is😂. But I’m thinking about taking mines off and put something else
@@Gaven.degenhardt.racing lmao this happened to me back in 2018 and it was VERY loud and I got disqualified
Always make sure to tighten the exhaust bracket nut periodically
I need more info
Where Could I Buy A Clutch?
Omar Cruz how about comet kart sales? Ever think of that?
What type of clutch is that
How much is a new clutch for a kt100
Around $300 new
where can i find a coil for one?
Zeta Assassin how about comet kart sales? Ever think of that?
i feel like its gonna blow when i have it running
And how much would it cost
1800
400 for a well used one
And then the 206 B&S came along and killed off he KT100. Sad. Now B&S is chapter 11
