Lol… this video was informative and entertaining… “this great big ass hole, is where the piston goes up and down” 😂

[@nunyabizzness5477]

A little advice for your viewers on changing the port widths. Make sure the cutouts in the sides of the piston, if it has any, will not allow the air fuel charge out of the port at any time. The easiest way to do this is with the cylinder still on the engine. Put a pencil point on the side of the port, and rotate the crank a few times all the way around so the piston rubs on the pencil as it goes past. Do this to both sides of all the ports you intend to modify. Remove the cylinder and see where your pencil marks are on the piston. You can widen the port so the lines are at least 2mm from the cutouts. Also, increasing the port timings by 1mm or so could make your engine have little to no bottom end acceleration. These mods could still have adverse effects on your engine's performance, so tread with caution. If you cannot afford to junk your engine, don't touch the widths or timings. Stick with cleaning up the trash! You will be surprised at the improvements that alone will make! Remember, air is like a fluid...easier in, easier out. You may also have to richen your jetting. Research reading spark plugs and piston wash. When in doubt, add more fuel. Start rich and go from there. I like your Happy Time Harry, Meatwad, and Mighty Mouse tattoos! Probably not too many people even know who they are or where they're from though... :(

[@Westhelockpicker]

@@HughesMotorized you got any advice on vacuum leak where the carb bolts on the intake? I can't tighten it anymore and it's definitely leaking cause of the high idle and if I spray carburetor cleaner there it brings the idle right down. I've seen videos of people putting a bead of silicone around it or wrapping a piece of an inner tube around it and using a hose clamp to tighten it. All kinds of shit

[@MichaelForrestChnl]

Good info although somewhat mislabeled. Porting mostly refers to widening and/or raising the ports right at the cylinder surface, not cleaning out casting irregularities.

[@HughesMotorized]

Note I did widen intake and exhaust along with lowering intake and raise exhaust ports

[@MichaelForrestChnl]

@@HughesMotorized I´m sorry I didnt watch more than the beginning where you said it was basic porting and then described it as cleaning up the passageways.

[@MichaelForrestChnl]

@@HughesMotorized also I would never give any generalized porting advice except for one type of cylinder after I have measured the durations and ran them along with port widths thru a porting calculator. If you say "always lower intake" and someone has a cylinder that already has the correct intake duration then you´ll cause him to mess it up and then he´ll have an engine harder to start.

What type of Polish do you use to Port intake and exhaust thank you

[@MrTarmonbarry]

You can start with course grade of emory paper , then go finer with the grit . finish with metal polist , a good one is ''solvol'' , its called chrome polish but will do the job fine . I used it on a zzr600 notorbike head for racing in what is called ''clubmans'' in the u.k . one of the important things ios matching the openings so the hole in the exhaust port of the head matches the exhaust pipe , same on the intake side. Typicaly the hole in the barrel of head will be smaller than the exaust and carb openings

[@HughesMotorized]

Yes I can. There are videos on it. You put a fresh sprk plug in and warm engine up. Run 30 seconds at full throttle. Kill it instantly, pull plug and see color. That will tell you how your jetting is for full throttle (main jet). THEN you put a fresh plug in, warm it up and run 30 seconds 1/2 throttle, kill it and look at plug. That will tell you how mid-range is working. Stock NT carb, slide needle regulates richness for midrange. Black pug = too rich. Whte deposit on plug = too lean. Coco brown color = just right

So porting is basically deburr sharp edges

[@HughesMotorized]

BASIC porting is that plus opening up the ports to allow more flow. You raise the exhaust 1mm and lower the intake 1mm. Widen both 2mm. More technical is to set specific port timing and duration

[@donttread5414]

I hand sanded some of the cylinder because my dremel slided when I was porting and caused some small scratches / pits in the cylinder. Some are saying that the interior of the cylinder has a special coating and that sanding the cylinder would ruin it. I used 150 and 300 grit sand paper. Do you think its ruined? edit: looks like the cylinder is 100% iron so theres no coating and therefore no damage via sanding, however I still got some small pits / scratches from my dremel sliding off and hitting the cylinder wall. Think it will cause any issues?

[@HughesMotorized]

Most have a chrome bore. That chrome is getting thinner and thinner over the years. If you sand, only remove burrs. Ride on

Hi Eugene. I am cleaning out the rubbish in the intakes and lowering the intake and raising the exhaust by 1 mm. So when you say you can leave the carburettor intake slightly rough, how rough do you mean. Do I still need to sand down the carbie intake or can I leave the little grooves from the Dremel in it? And just sand the exhaust intake smooth. Or do you recommend sanding both intakes? Thank you so much for all your help!👍👌

[@HughesMotorized]

You want to sand both intake and exhaust where they go into cylinder so a ring wont snag on a burr, polish up exhaust and scuff up inside of intake.

Do you advise waiting till after running a tank or two for break in first before porting the cylinder out? Or is it fine to go ahead and port match the exhaust and intake before installing the motor (before break in or running at all) thanks @Hughes Motorized

[@HughesMotorized]

I'd say do it before running is best

[@marthamryglod291]

On the motors I build for myself, I always clean up the ports and match the intake, transfers, and exhaust ports before running the motor. After break-in, I decide if the cleaned-up motor is delivering what I want. Then I will modify the port timing and spend time opening up the exhaust as much as possible. What this video says is fantastic advice for just "winging it" without doing any port timing calculations.

Thank you Eugene! Your videos are awesome. Well done! Agree, don't need to go fast on these motors. I live in a hilly neighborhood, and think cleaning the junk out will help as described. But, do you think I am better off not to take 1mm off on In/Out ports, so I don't lose the bottom end torque? I also don't get a smooth power flow, and the motor is past breaking-in period.

I have found you are better off just widening the ports slightly and you keep the bottom end speed and keep and gain top speed to my bike is stock with just the ports done and I get 48 mph lol

80cc engine?

Stay safe and ride safe scoot scoot around 🥰😘💋💯🤗

[@HughesMotorized]

Always!

[@MileytheJeepV2]

You don't necessarily need to go fast just because you have the crank balanced... thats kinda like if I say nope gotta buy a car that governs at 70 cause why would I need to go 100 the top speed limit is 70

[@MileytheJeepV2]

I feel the sane way when it comes to speed I don't think going over 40 is safe on a bicycle but a balanced crank might make my ride smoother even if I never hit my top speed

[@HughesMotorized]

Amen. My point about balancing is the engine will only hit so many RPMs due to balance issues. A better balanced engine will ride better and last longer as I see it. Thanks for watching

So small 950 watt harbor freight generators head gasket and head fits motorized kits with little modification just drill the holes a little bit bigger to fit the studs I think the piston and piston bearing fit too the head takes a bigger spark plug just wanted to let everybody know just in case you have one mine didn't work I cannibalized it
