MOPED ARMY

id assume it was a puch crank since the '77 dudes used a puch polini kit with it... the puch stroke is what 43mm and think the pug is like 39.something mm? but yeah im not positive just kinda guessing

what if i put it on a puch maxi N? will it be cool then? i'm one of 2 or 3 moped dudes round here. and it won't be hard, i got stuff. and i'm a master backyard fabricator. the swing and the spring are pie. getting a variator on it won't be hard. if worst comes to worst i have thought about trashing an old 2 shoe, and changing tapers. i got a metal lathe, a big ol arbor press, and a welder set up for steel. and i think i can make a peugeot pedal shaft fit right in there, pulley and all. with some persuasion of course. bearing walk? bearings only walk on tuesdays here in GA, so i just won't ride it on tuesdays.

putting it on a puch maxi N would be disasterous. they sit super low to the ground and it still needs to variate....good luck with that.

piston port crank wont work in an e50. tried it. you would end up putting holes in your crankcase just to get it to fit. plus the crank weighs a ton and will defeat the purpose of the engine. this is the thing, your taking impossible to find parts and possibly destroying them. why not just build a derbi with a 70cc metra kit like everyone else and have a sick fast bike that you can replace parts on and ride everyday? or, god forbid, a fucking motobecane that will smoke every other bike around with off the shelf parts? or, a hobbit that will scream for under 400 dollars? i'll tell you what. give me 10000 dollars and i'll build you a variated puch. deal? cause thats about how much labor went into building that fucking thing. why use a tjt when you can use a variotop? or put a minerelli crank in it and run scooter tech? or buy a scooter. that might be more up your alley.

i'm only discouraging the idea of building it because it's not worth it. the only benefit of the entire build over a moby was being able to use a puch polini. if someone wants to build it they can. we never said we were the first to think of it. we were just the only ones stupid enough to actually do it. use a moby transmission and make it swing. simple enough. best of luck to you.

out of curiosity, have you guys had a chance to open it up all the way yet? i'm just wondering what the top speed is on that monster. i already know its fucking quicker than any moped ive probably ever seen (somebody prove this wrong, i wanna see it. for real.) but im curious how fast it can get at the top end?

Super secret variator as in bolted right on eh Lee?

ha ha he spilled the beans!!! i got a scooter double variator, maybe i'll just do that. w/ a snow mobile motor swinging on a maxi n all raked out to accomodeate the new stuffs. and blast.

the e-5 in it's current state tops out around 56mph. it gets there in the distance from 16th to 17th on capp st in sanfrancisco. here's the top secret tech. a moby clutchless variator fits on a puch crank almost perfectly. the way i made it not fly off, because the direction of a flipped e50 spinning it's normal way would throw the clutch nut off like a sachs, is to tap the inside of the crank to m6 and run a secondary bolt/washer holding it in place. it has yet to even come loose. the next "variation" of the bike will probobly be the fastest shit around, if all goes as planned. same concept, this time just not built in a month with broken parts. and literally every part on that engine with the exception of the ignition is in some way broken. also, dear zach. swinging an engine is not stupid. get your mind out of derbi's for a minute. i miss you. come play pool again. dear jarrett, i fucking miss you so much man. i wish you were right here next to me building this bike. move here already.

dear everyone:

The ONLY reason to variate an e-50 is to use a puch kit such as a puch polini kit. the best kit around.

Here is what went into it that makes it so difficult:

e-50 case chopped in half and flipped upside down. A new groove for the snap-ring bearing was machined in the case. engine holder bolted to the case bolts was fabricated from stock metal by welding. ignition: easy. Variator: easy.

The beauty of the engine, and the reason it works so well, is that it is made of entirely puch parts, sans transmission.

HOWEVER, This was a very complicated build that was a complete failure the first time. V 1.0 had points ignition, a used kit, and an engine holder that was too weak, and a spring that kept falling off. The bike ran really fast, but the ignition advance was too much and we detonated the piston. and then the engine holder cracked, and we were blowing condensers all day long.

V 2.0 happened about one month later. We completely redesigned the engine holder, making it much sturdier. We completely fabricated a spring mount similar to the doppler performance spring, which took some serious planning. We PURCHASED a hpi ignition, the best decision we have made so far, hahaha. We found another used kit which was in much better condition. Version 2 was a success.

total hours spent on version 2 alone are about 30-40 hours. Version 1 was more like 50 hours. We spent literally day and night trying out different ideas. We made so many different designs, and one after the other, they failed and failed.

So im not saying dont do it, im saying that the only reason for this build was to use a puch polini, or a gilardoni, or your favorite kit. At this point, it is pretty much no longer a puch. infact, the motor will never fit on a puch! HA!

Anyhow, the build is sick and next season we are hoping for it to crush 65mph on the track and get there even faster than it does now.

heres a little secret: 30mm carb.

tight :)

tight!!!!!!!!!

light weight in the right places and proper pipe selection is the true secret to this build, using a puch motor doesn't really matter.

I suppose that anything can be done but is it worth the effort? Why not just go Peugeot all the way? Case inducted from the factory. Lots of speed parts, even new cases. Some have even managed a dual variator setup on a 103, but unfortunately those that have are in France as far as I know.

e50 = high rpms + variator = blastiness.

pug 103 cannot compete in the races anymore, it as been pretty much phased out. the reason is that the pug parts are simply not as well designed as motobecane, and even the 70cc kits for pugs are more like 65cc. moby kits are true 70s.

bikes left to choose from to place at the races:

derbi flat reed, honda hobbit, e-5, and thats about it. in fact, i'm pretty sure its gonna be like all derbis this year, but i don't care, fuck it, puch polini for the win!
