Changing the gear ratio is the best and easiest way to make a small cc bike feel more powerful.

Idk why people write so much hate to you. I have a 50cc and I am just like you, I like trying homemade things to make my moped better. I love your videos!

many years ago I had a single cylinder 185 suzuki 2 stroke that had 2 spark plugs in the head so if one fouled you could swap the lead to the other one for a fresh plug. But what I did was add another coil & lead to the second plug so both were firing & it made a huge difference way more low down power & always started so easy.

the steady spark is because it connects the closest points. with the original the surfaces are parallel and spark can form anywhere between the parallel surfaces but will have the same power every time. With the side gap the location of the spark is constant and will wear the side of the electrode then the gap will increase. It is possible the flame will travel slightly better because it can spread in all directions initially but hard to tell if it helps without clear tests

Side gapping is used in Racing . High Fuel Ratios and High temperatures . Side gap plugs dissipate heat from themselves quicker to avoid overheating and Melting the Electrodes . The Plugs do NOT make more Power . Even a High-end MSD ignition doesn't . What happens is MISFIRES are eliminated .

I've been grinding my spark plugs since the 1960s, except the Iridium plugs. [Dodge D-50 2.6 5 spd.] I VASCAR tested 1/8 mile of 3 runs (averaged) & went from 14.25 to 13.75 seconds. My mpg's also went up. __ CHEERS 😉

Mess with the carb a little bit. That screw on the side where you can change the idle, idle up a tad and try that

David Vizard covered this topic in a video as well as writing about it in one of the books he has written.

For all the comments putting down his testing. This is simply some of the ways you get in the fast lane. Test and trail. If you don't like it just stay over there in the slow lane👍

There are weird spark plugs out there like Brisk, that one doesn't have a hook. I tried it and it works like a spark plug.

They prob side gapped plugs too run shit loads more fuel without fouling plugs guessing

The ignition has to be able to create the spark longer too. I used side gapped plugs in 2 stroke engines turning 20,000 rpm. But the pumper carbs had externally adjustable low and high speed jets .The plugs were alot foul resistant in 2 strokes for sure

I side gap my 2 stroke lawnmower spark plug, it stops fouling. My nieces husband came for a visit, his car wouldn't start so I removed the plugs, the outer electrode was almost completely burnt off so I gapped what was left re fitted them and it ran.

love you vids zoomin' ❤

Good info dude! Now do research on indexing spark plugs. If you index them, you'll get the electrode facing directly at the fuel air mix when it enters the engine making even more power

You should make a double tip/ gap spark plug and see if it's better

For you to get anything from the plug if you got more consistent spark you would need to alter the gas and air mix because it most probably running lean and the plug is burning it up quickly and if that helps but doesn't solve problem change jets size for more fuel

Side spark in racing has nothing to do with the ground terminal blocking the combustion. When the spark "dances" it changes length and there fore temp. Racing calls for consistency of high performance precision at the cost of longevity. You electrode and ground post are going to concentrate all of the wear in one "laser" spot increasing gap wear quickly out of optimal range. Not an issue if you change them after every race.

Mazda rotary engines use a triple ground. I have felt a change in performance using those years ago. They are more of a side shooter.

Different spark plug gaps subtlety alter the timing of the spark. And different timing affects power output. That's a fact.

Lov your vids

45° cut is ideal . Can not rEcall if it's right or left .

where do ya live ? my buddy has a motorcycle dyno

You can try to advance the cam by 1 tooth or 10 degrees. The stator coil pickup might be able to be modified so you can advance the timing a few degrees

Mercury boat, spark plug is what you need

If I had that xr100 and was desperate for more power I'd sell it and get the 400 as a step up or the 650r which is in my opinion the best enduro I've ever owned wish Honda would make them again

Put a iridium (good Ngk) and see the difference in perfomance.

In our 1000 HP BBC, we closed the gap to about .025"...

I did this with a half clapped out plug on my Stihl backpack blower the other day and no shit..... Starts quicker every damn time now. One pull, always.

looking at your spark plug its fooled you need to adjust your mixture also keep the plug standard with the correct gap and also your carb is junk because the carb has the choke butterfly in the way at the rear that stops power chuck in bin by a cheap molkt brill carb that will fit and finaly change your sprocket up a tooth for higher top end 1 tooth less for more acceleration but less top end , you got to get the combos right .

Find your high speed best mixture by getting some jets that are a little bigger and a little smaller than what you have stock. With no other mods on the bike tuning the carb will be best bet. Do the high speed tuning to determine jet size at full rpm. I will assume you need a smaller jet than what you currently have. Then set that needle up a position at a time until your revving from idle on up is the quickest it can be, ie, no bog. Do this and you will be surprised I think. Maybe after getting good air fuel ratios you can play with modded plugs. Good luck!

Your spark plug modification made the bike greased slightly. Holy cow can barely see it

Now you have to retune the carburetor to the plug

The only way more spark will give you more power is if you’re dumping more fuel than can burn with original spark. But more fuel can’t burn without more air. The key to horsepower is air. That’s the first thing you need to gain power. Once you get more air in it you can add fuel. And unless you’re dumping a lot more fuel in it I’m sure your original spark can handle it. It is fun to try though lol. Keep at it young man.

Just use a twin pointed sparkplug like Denso TT. They won't let the spark dance at the edge and destroy it.

I'd like to see the video where he's replacing his valves hahaha

Keep on trying. Don't stop your curiosity. That's how we keep inventing ,thinking outside the box imagine if we stop after the cave man finished with the stone wheel.😅😅😅 thanks for your time to show the difference it makes just by simply cutting the gap a little at a time .

If you want more power, get better exhaust flow better air flow into the engine and more fuel, bigger exhaust, bigger carb for starters

Guys don’t do dumb shit with your spark plug, you only have 1 of 2 things, normal combustion and abnormal combustion If you have a problem then modifying a spark plug will not solve the problem An electrical engineer figured this out and KZfaq can’t make it better, if this mattered NGK would just make this plug and sell it to you BTW did you notice the spark jumping to ground without crossing the gap first, this plug has a carbon track on the porcelain which is likely the problem

It has more power But not to much when u cut it

now if you paint the plugs bright pink and put some plastic over the electrode a tank of petrol will last forever

Put some shinko 705’s on the katana and rip it off-road

I'm no expert but in order to gain power from firing you would have to change your stater and CDI and higher voltage coil. You can buy high performance cdi boxes and they will boost engine performance. I put a high performance cdi on my son's pit bike and it made a world of difference in the throttle response and cruising. It was so much smoother than the factory when I first started it I had to adjust the idle down cause it was idling 6 to 800 rpm more with no fuel change and when you held it at a constant rpm speed it so smooth. Also you can buy offset keyways to advance your timing. Just wanted to share for all the keyboard warriors saying that spark won't help performance clearly never set the timing on a small block or anything for that matter. Timing and spark are very important you could have the biggest baddest built engine in the world with the biggest fuel system but without proper timing and spark you have the worst performing engine. Also if you want better spark don't cut your plugs just go to the Auto parts store and get the hottest spark plug you can get in that size which will more than likely be a ngk or E3. The E3's are great plugs I noticed smoother engine idle etc with them especially in 2 strokes.

For more power on the wheels you have to change the bike with bigger cc . No need to think about small modified thinks . It will not work . Other bike like competition models will please your demands :) Best regards ! :)

lol smaller area=faster erosion. 4:29 if you can start it like that, don't mind about your spark.

leave the spark plug alone, if the bike is not meant to have side spark spark plugs then there is a chance the engine will run hotter and you will burn your valves just like running a lean tune

I'm sorry I don't see much of a result look like the same thing to me

Hey man I watched your video and did this and now my bike is siezed.. what happened bruh

Hope you don't melt your piston.

put a 28mm carburetor and put a 17 teeth primary sprocket and you will Rock 🎉

Just low on blinker fluid" 😂

Too small of a motor to notice any power gains using the butt dyno. Sounds like it ran good though. Cool vid...👍

Better keep it cleaner than a surgeons scalpel with that tiny point of contact or you will get miss fire alot guys they aren't as reliable long term obviously

On a small bike engine with,let’s be fair, a small horsepower figure, there’s never going to be an magical and noticeable gain from a spark plug. It’s either going to work or not. What you’d be better doing is playing around with the timing of the spark and seeing what you lose or gain across your power curve. But if you love that bike and enjoy tinkering, drop in a larger lump. 👍

Why not just get an iridium plug you can gap it probably and get a sharper spark

Put iridium plug in it for more power

Turn the idle up on the bike bro

Thanks darth vader 💀

Grinding material spark plug just make it Last less you expose normal metal then so it work even worst now

Port and polish the cylinder

It takes more than just more spark to increase power and the only reason you need more spark is when you make fuel upgrades and air upgrades because with more fuel and more air in order to burn it all correctly you then need a hotter more powerful spark so yes side gapping will help but only if you have increased fuel and air to the point a stock plug cant burn hot enough to burn all the fuel your pumping into. From the looks of it your bike is basically just a off the floor normal stock bike so really all yourr doing is hurting your performance unless you get a bore kit a bad ass carb setup wiith bigger jets and a better air intake set up. Not trying to bash on ya kid just trying to help.

I hope he never takes off his helmet

Try 3 points plug. Bro

To inform you After that you will have starting problems The same is at low revs

I dont think cutting a plug does do anything. As long as the fuel gets ignited on time the power pushing the piston down doesnt have anything to do with the spark.

missed split fire type

If your desperate for more power, and willing to possibly sack your topend. Tweak the pick up sensor mounted on the case and shift it a degree or 2 counter clockwise. I may blow you bike up if your running 87 octane fuel out of the pump. Get fresh 91 but only fill up your gas can after filling you car. About a gallon of 87 will probably sitting in the fuel hose on the gas pump.

Take it in and have a Dino B4 and after

Keep. The gap to spec or you will start frying electronics

if you need more power get go green and get a kx 500

Kid feathering that clutch or power shifting

Excellent 👌👌 job

Pipe jet kit and spark advancer

Rather go with a multi point spark plug, the gap should be something you don't mess with, just because of that, there are plenty of ways to gain hp and this isn't one of them...

if youre that needy for more power, then port match intake port to throttle body, and exhaust port to headers, and spen 10 bucks on iridium spark plugs. edit, fix your damn compression!! youll get that 10 hp by fixing your damn motor

I could not bear to watch at 4:17 all the muck around the open spark plug hole ready to drop right into the cylinder...use compressed air or a soft brush to clean that area before removing plug, please!.

Use iridium plugs...

RIP piston.

this was not a lame video

You can not go off that video they were using a plug tester with WAY more power that any bike ignition could ever produce, run the right plug with the right gap and leave it alone.

Bro you just CANT get more power by increasing the Electricity! You need MORE Fuel and MORE oxygen! NOT ELECTRICITY

If it were that simple to get extra BHP for nothing, you don't think the big 4 bike manufactures would of done this years ago?

Run crude oil in your bike

Why is the fool wearing a helmet, side gapping is a total insane idea.

Try Arc lighter plasma

Really

Just use Coil of Suzuki A100.

The whole rationale here seems to be nothing more than supposition but with no proof, sounds ropey to me

Just get a bigger motor for more power or you can modify the motor you have if you know what you are doing.

Works better on 2 strokes

dont be surprised when you burn a hole in a piston

If an engine was meant to have a side gap plug it would have been designed for it.

Take a bottle put fuel in the bottom so it’s filled with fumes Put any spark in there Kaboom dude The size of the spark matters not the engine specs are where the power comes from. It’s measured Dancing moving around lolol that makes more horsepower lol

I opened the gap on my plug from .025 to .040 & gained a little more torque. More than I was expecting yo for sure

Change coil overs instead

First question before I ask any others is why are you doing this video with your helmet on???😂 Something fishy going on Willis!!!😂😂😂😅

Run AV Gas in it.

this kid does everything we want to try bot are too scared to do

10 more hp on a 25hp bike 😂..Good luck geezer

A mi me funciono le dio más reacción de aceleración y un poko más de potencia yo tengo una moto 2 tiempos
