Puch E50 Hi-Torque cylinder porting

Just the break down of the best porting map ive found for hi torque cylinders!

[@TwostrokePuchwizard]

love what you are doing here!

[@macschmitz9194]

Thanks man

[@TwostrokePuchwizard]

I had mine done by Devin Biek a long time ago and it still rips

[@macschmitz9194]

Its the most dependable build i have!

[@raycannon7514]

Have you ported big bore kits before?

[@rootstowingsyogahealingnew2101]

Finally about to do this. What kind of gains would you see with a bing 14/15 and no case match? I mean the transfers are bigger on an airsal 65 and those will do 44-45 with a case match, but this would be so simple to do if the gains were worthwhile

[@jayangle3413]

Man I I have the same question about if he case matched it ???

[@jayangle3413]

He did case match it.

[@rootstowingsyogahealingnew2101]

I dont need a for sure timeframe on them, just something before spring. I could also take a run at doing it myself if you gave me the port map with the transfers. Four kids myself.

[@charlesrknottsjr]

Are you still working on mopeds

[@effie5125]

Winter project!

[@johnrobinson357]

Mr Schmitz. I am an old timer.....that still holds mopeds dear. The first thing i ever owned that took me over 40 mph. Was a 1975 vintage E50. Could you post a photograph of a pencil drawing of the port mods so i can see in my mind and translate that to the bore. I can envision what you have done and probably could proceed from there. This sounds to me like a short money fix to get speed and have the bulletproof nature of a stock cylinder. Correct ? A little direction is all i need. Thank You for any information given, I do not want to kit the bike unless i must - 35 or 40 mph is enough for me. more is good but dependability is key .

[@johnrobinson357]

Actually upon watching this again - not so late at night - i think i have all i need to screw up my own cylinder. I will use a spare 1st. I don't expect much but i will see for myself in time - Thanks for sharing and posting.

[@StephenDanielAddeo]

What carb are you running? You port matched the case also? Good video!

[@macschmitz9194]

Mikuni Vm18 and yes case matched. You can run it with only doing the exhaust and intake porting and not touching the transfers you'll still see gains from it.

[@seniornuggtes]

hey mac! would you still be interested in porting a cylinder?

[@TheBostonTom]

What's it like off the line. Most 50cc kits really bog off the line.

[@rootstowingsyogahealingnew2101]

great video. what do you mean by raise the exhaust port 2 mm? do you mean widen the exhaust port 2mm all the way around?

[@macschmitz9194]

I usually go 1.5mm each side and raise the exhaust 2-2.5mm. And by "raise" I'm saying going up towards the top of the cylinder.

[@rootstowingsyogahealingnew2101]

@@macschmitz9194 you still porting cylinders for folks? I have two e50 hi torques and an aluminum I could send you or it might be easier for you to send me if you have stock. i'd love to do it but don't have the tools.

[@matthewcox5302]

Great video. Do you leave the ignition timing standard?

[@matthewcox5302]

ok, thanks.

[@davidmaisonette6022]

You can also shorten your piston for more port time duration

[@macschmitz9194]

David maisonette the top of the piston skirt is shorted by 3mm

[@dutchmilla2794]

Fuckin love it bro power porting

[@guidosamson682]

We work with open in degrees on ports. Not millimeters

[@macschmitz9194]

@Guido Samson This is about dumbing it down for the average guy in his garage trying to make a stock moped faster. Talking in degrees tends to confuse people.

[@TheNkuebelbeck]

Hey-I acquired a hi torque. Would you still be down porting it for me?

[@rootstowingsyogahealingnew2101]

Do you still port cylinders for folks? I have two e50 hi torques i'd like to do. do you case match or not needed?

[@macschmitz9194]

Case matching would be needed. Also I do them for people here and there but I wouldn't be able to put a for sure time frame on them. Three kids and a full time job really damper the hobbies!

[@TheNkuebelbeck]

Would this work on standard cylinder? Not the high torque version

[@macschmitz9194]

Haven't done it myself on a aluminum cylinder 1.5 hp which is what cylinder I'm assuming your talking about?

[@TheNkuebelbeck]

@@macschmitz9194 2hp puch maxi. Stock e50.

[@macschmitz9194]

@@TheNkuebelbeck is it aluminum or cast iron?

[@TheNkuebelbeck]

@@macschmitz9194 technically I think it's a nickel sleeve and aluminum fins.

[@macschmitz9194]

@@TheNkuebelbeck yeah you could still do a basic port job on it similar to what I did here.

[@marianomumpower]

yo, when youre saying 'mils' , you actually mean millimeters.. a 'mil' is a thousanths of an inch

[@macschmitz9194]

mm

[@marianomumpower]

+Mac Schmitz ok. ya, definitely not the same thing.. good video, just dont say mils 🙊
