Have you ported big bore kits before?

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

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.

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.

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!

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.
