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.
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
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!
@@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.
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.
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 .
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.
@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.
love what you are doing here!
Thanks man
I had mine done by Devin Biek a long time ago and it still rips
Its the most dependable build i have!
Have you ported big bore kits before?
Hey-I acquired a hi torque. Would you still be down porting it for me?

Man I I have the same question about if he case matched it ???
He did case match it.
Winter project!
What's it like off the line. Most 50cc kits really bog off the line.
hey mac! would you still be interested in porting a cylinder?
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?
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!
Great video. Do you leave the ignition timing standard?
ok, thanks.
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?
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.

You can also shorten your piston for more port time duration
David maisonette the top of the piston skirt is shorted by 3mm
Fuckin love it bro power porting
What carb are you running? You port matched the case also? Good video!

We work with open in degrees on ports. Not millimeters
@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.
Would this work on standard cylinder? Not the high torque version
Haven't done it myself on a aluminum cylinder 1.5 hp which is what cylinder I'm assuming your talking about?
@@macschmitz9194 2hp puch maxi. Stock e50.
@@TheNkuebelbeck is it aluminum or cast iron?
@@macschmitz9194 technically I think it's a nickel sleeve and aluminum fins.
@@TheNkuebelbeck yeah you could still do a basic port job on it similar to what I did here.
yo, when youre saying 'mils' , you actually mean millimeters.. a 'mil' is a thousanths of an inch
mm
+Mac Schmitz ok. ya, definitely not the same thing.. good video, just dont say mils 🙊
