Re: The infamous Puch post

I guess it could be done with a dremel if you are really talented. I took sanpaper wrapped around a toilet paper roll and slowly opened it up... took about 10 hours total. Then I smoothed it upwith a dremel fine sandpaper bit. The hard part is the circle must grow to about 53mm without getting offset. It has to stay perfectly centered between the post holes. I probably hsould of had it machined but I'm cheap.


Re: The infamous Puch post

here's the size of the hole afterwards... now the sleeve should NOT be a tight fit because the sleeve could become distorted and place drag on the piston, the cylinder should slide in.

I recently just got my moped and am looking to put a kit on it . Where can i find the $285 Athena 70cc/17mm amal carb kit that includes basically everything to redo the engine and the $185 Polini 64cc with the reedvalve kit and intake manifold (for a 15mm Bing carb that goes for around $70). What exhaust would also be compatible with any of these kits. So if anyone can tell me what sites these kits and parts are on that would be cool.

Hey everyone, I haven't forgotten about this post and I definetley plan to go through with it. The kits just came back in stock at Moped Warehouse and I ordered the Athena 70cc and it got here in 3 days! The website is already designed and everything so I know have the Proma Exhaust and the 70cc kit.

I will be posting again soon once I find a good place to serve the site,

Hope some of you guys are still intrested!



I know this is an ancient post... just wondered if any progress has since been made.

alas, the best laid plans of mice and men...

Re: yo...

ohh mann taht 80cc looked. im willing to do the dremelwork on my moped to get the 80cc kit bolted. in i just dont know how hard it is to get a pipe and intake on it. mopedwarehouse picture looks like it already has a intake manifold coming from it. i just need enough money to get a massive carb to go along with it. im guessing the dellorto phbg from 1977mopeds. but this is all assuming i can manage to check if my tranny is still good. its a 2 speed


sad... really wanted to see it. on another note, i seem to recall you mentioning some technical stuff about expansion chambers. do you know what information is needed to properly design a chamber? i can get the sections cut and rolled no problem, but the fluid dynamics is WAY beyond me

Re: yep..

yeah sure

email me or catch me on aim and we'll talk about it, its kinda like buying a custom suit or something, i'll need some measurements from you, and to kinda know how you want it to run, then i'll come up with some critical dimensions.
