So, I built up a bike for a friend with the old style canister muffler on an AV7, and it shook that pipe to bits in a matter of minutes.Anyone have a used stocker for sale? Hit me up @Motodrachen on Telegram, PM here, or Motodrachen@Gmail.com Thanks!

Read up, plenty of info on puch.

It's okay, I did too, thinking it was gonna be Okay, you know? Those $60 malossi reeds are probably only like... A little better, right?I got spoiled by how good Athena AV10 reeds are.

Hey Jbot, how thick are the reeds you're using?
Max Johnson — 6 years ago
Garbage, the reeds are too stiff, the stops are too restrictive, and the middle rib in the cage does nothing.I'm running one now because waste not want not, but it's just the reed cage and stops, I had to tap it for screws, make new reeds out of malossi paper, stuff it with epoxy and cut it, lap it, and hammer out the reed stops into a better profile. Now it works okay.

Good luck. I just wrapped up a 70cc daily rider for a friend, they need so much damn attention to get them reliable again.The good news is that Motobecanes will make you a Very patient mechanic. the bad news is that they're into BDSM and will do their best to make you cry.

You can have both, it just means you have to Cheat. Aux exhaust ports, reeds, boost ports, stuffed crank, and a decent midrange pipe will let you keep the stock cylinder and carb but still have plenty of low and top end.That stuffed crank is Vital, I've put two in bikes recently and the power increase on reed valved bikes is substantial.

Hero Puch cylinders on stuffed cranks can deliver kickass low end and serious top end performance if ported out correctly. Problem is, no pipes will fit, the porting takes hours, and to unlock maximum potential, a reed block needs to be added on.But then you get a cast iron lined, reed valved, high revving, aux exhaust ported, giant finned, 65cc ripper that doesn't like to lock up like a Pol

Switch, Alternating current and Pulsed current.

Mine hasn't needed much screwing around with, mostly it was getting the airbox and ignition timing just right.But seriously, best carb I've ever had, for under $20. The throttle response and speed of dialing in (And the ability to adjust on the go) is a huge plus. Well worth the time to figure out.

I'd buy it just for the engine, and run it on a Maxi. No one would suspect a thing.

Make up a reed spacer and add reeds. Requires wizardry, but cheapest way to add a ton of power all around.

Now I wanna mod my cases for a small reed block, and run a piston port cylinder with little pumper carbs on both. It'll make tuning easy, and let me run a 14mm carb on the cases behind a small reed, and a 21mm carb on the piston port.Better low end, and way better top end.

I suspect the port tunnels are there to direct flow and keep port velocity high for more low end scavenging.they're probably not thinking of us crazy people.
Max Johnson — 6 years ago
The reason your compression is so high IS that squish band. That's the idea, pressure increases dramatically as the clearance between the piston and the squish is reduced.I've had middling results with the Tecno circuit, it didn't provide the boost I was expecting, possibly because of the long stinger that looks awesome but must not flow super well.

Nah man, that was two jobs ago, they're all sitting on a shelf in fall river gathering dust....Well... Not ALL of them.

Are you gonna Jbot port the DR kit?
Max Johnson — 6 years ago
Jbot, why did you steal a Fury Road prop? That thing belongs in the outback, it's natural habitat.
Max Johnson — 6 years ago
Killing... Base gaskets?Personally, I run a lapped flat head and cylinder, no gasket. You still get oil oozing out, but great compression.For the base gasket, I cut my own from medium thickness gasket paper from autozone by marking a 26mm radius circle with a pair of calipers, and applying grease to the surface of the cylinder. The grease transfers an image onto the paper that I cut out with a

That has to be some of the cleanest porting I've yet seen.

Get a stock, used moped and work it up from there. It'll make you appriciate all the ridability and speed you'll be adding to have something stock to compare to.Peugeots are hard mode tho. And motobecanes are "I'm into Pain' mode as a first bike. Between 1977 and 2016, the bike will either need half the components serviced and or replaced, or somebody has Messed with it

Seconding leather clutch pads, you just need to abraid the pads with 2 ton epoxy on them so the epoxy sticks to the aluminum and not to the oxide layer that will form.They slip just right, and I'm running a stiffer spring on 2'nd gear.

I run a BX on a gy6 variator on my motobecane, it fits the rear pulley just fine, and it's a 16mm belt, not a 12.5mm belt.
Max Johnson — 6 years ago
We need a hundred fifty of these in America.
Max Johnson — 6 years ago
Gas strut solves your problem by including a damping effect. You can run a BX30 belt on there, and it'll be tight at first but wear in to a perfect fit and they're like ten bucks on Mcmaster-carr.

The exhaust port is So small that drilling in auxiliary ports is a breeze. I blasted a huge exhaust port in a pa501 cylinder with Jbot's aux port method.

That's some serious grudge thread necromancy.

You can cut a squish on your stock head. I might have a cut head lying around here though...It sounds like it's shifting after the torque peak now. You Can raise or widen the exhaust port on those kits, or even do the jbot craziness of aux exhaust ports or a semibridged port to get more blowdown or top end power.
