I hear ya, with mopeds all out in the open I can never understand when someone complains about working on one. Sooo easy in comparison!

Not sure... we were just talking about this yesterday, the number of mergers and changing of hands in the motorbike industry. It has happened quite often. Seemingly for different reasons, but common all the same.

The Moroni options are all over the place. There is a change in the cases somewhere in the early 80’s... and depending on which engine you have the kits available may or may not fit easily (the cylinder skirt doesn’t clear)

Got to you, or got you grovin 😵‍💫

Interesting... where are you located??

@@MopedProblems I’m from the Bronx ny and I also have a place in Bergenfield nj

@@MopedProblems I’m sure we have met before and I think I sold you guys some mopeds before and I know you know my buddy the guru chris at moped warehouse

I'd love to see it!

You thought so...just sayin'

Trail tec has a little one. I’ve carried them in the shop before. Most people find the trail tec temperature gauge more useful

I use a spark plug thread chaser... not exactly the right use of the tool, but I’ve been able to quickly square up a head in the lathe this way.

Kinetic can be tough but they are clones of the old school Vespa Mopeds, which had a ton of speed mods. The vespas had a dual variated transmission that helped for overall pickup and speed... the kinetics do not have this... it would be cool to see Vespa parts switched over to the kinetic

Sometimes they sell kits with heads on them. Already cut for the squish band. Is that available for your engine?

Best bikes for sure

Big bubba, this is the Addly Rough House? Should be just as straight forward was any 2 stroke scooter. I would expect 10 mph faster with more launch on the way. Always best accompanied with a exhaust pipe and variator tuning

This is for the cylinder upgrade 50cc to 64cc. Got to add that ramp to avoid detonation.

I get that

I got 3 mopeds and 1 is 65cc head got cut alot for higher compression and getting 12psi no problem working 2 years now

There’s a lot to investigate. In general if a bike has good spark, compression and fuel/air flow it should work. But there are things outside of this that can throw you off, like bad seals or air leaks. One of these days I should set up a Patreon for Moped coaching out of NYC

I got it ....tossed the exhaust in the fire pit... Runs great!

Not sure bud, they are here in America, but you’ll have to see if anyone ships internationally 🤔

@@MopedProblems thank you but need phone,adress or contact.

It’s been a standard move at the shop. We’ve done it a hundred times at least. Never been a problem.

Actually that’s the plan in the couple of weeks!

Nice looking foward to it

The polini 80cc is the best kit for Minarelli motors. Top top top!!! Huge improvement over the stock cylinder... especially when matched with a good performance pipe

There are performance heads available, but we usually modify the stock one in the lathe to match better. Similar to the video

We shoot for .7-.9mm squish. Measured by solder. When customers do kit installation themselves, they often skip this step... which i agree is a bad idea.

It’s true, the Polini kit was always a powerful but delicate option. I’ve heard many theories to why they fail. But getting down to it, the Metra 64 (kit I am recommending in the vid) just doesn’t have those problems.

@@MopedProblems yeah from my experience it always caught the ring in the exhaust port on the upstroke and broke it along with a part of the piston head. I recall people saying it may be due to the cold intake and hot exhaust gases deforming the aluminum cylinder, leading to the ring being pushed out into the fairly large exhaust port. Could also be due to imperfect timing, but who knows.. I just know that I didn't have enough money to figure it out! Lol.

We never got the slower bikes in the States, but I have seen them. Different cylinders. Definitely restricted overall and different sprockets

The 25 km/h has lower compression (achieved by thicker gasket - it drops compression to 6:1 or something similar) and it uses 12 mm dellorto carb (45 km/h uses 14 mm version)

It all depends on the size of the kit. Measure the bore and cut the same into the head. If the kit comes with a matching head gasket, that’s a good tracing tool

Moped Problems ok, I bought the same kit you did. I’ll trace it. I’m curios on the curve of the slope. Do you just cut it smooth?

I don’t know the whole story but I know they were bought by a company called HERO. They kept it up for a few years but are totally gone now.

sold to piaggio

This kit would, but there would need to be modifications to the intake and exhaust.... Probably not worth it since there are other kits that bolt onto a TOMOS perfectly.

I’d reference the piston head. In this case I cut at 19 degrees. I would say the moped ranges i’ve seen is 18-23 degrees. Find the piston head angle and add 1 degree.

@@MopedProblems thank you.

Yes, the Vespa/Piaggio mopeds (si, grande, ciao) all have a simple crank lobe window rotary induction.

@@MopedProblems do you have any of these rotory valve mopeds for sale???

No the head is to small

The larger size is only part of it, the larger kits also have larger transfer ports and larger intake and exhaust ports. Depending on what carb and pipe your pairing it with, you can get much more HP

I have a tomos i want it to be quick off the line what kind of setup should i have intake gearing and exhaust cyl head? its a a35

We like to call it avoiding detonation.

@@MopedProblems what? Dude The ratio is nowhere near The risk of even pinging... 🤦‍♂️

@@Kokaiinum1 this is a static points ignition, it can ping easily. Also, why have a squish band at all… why not a flat head with a spark plug in the middle? …give it a try, maximum compression! Let me know how it goes.

My favorite kit (that's affordable) is the DR kit. 70cc and cast iron, fantastic quality.

diggy dice i stay in la cops really dont care about mopeds

diggy dice yeah man give me the link .. thnxs 👍👌

Wish I could. Our editing skills get better in latter videos

I hear you Clay! I commented back in the other video. Alukit 👍

Same techniques. I would use an actual TOMOS kit on a TOMOS.... while it would work because the stroke and stud pattern is the same, a custom intake and exhaust would have to be made. Lots of extra work when a “bolt on” kit is available

The stator plate has slotted mounting holes, it can be adjusted a little for fine tuning

Yes. Otherwise is the spark too late with igniting the gasoline and air mixture. So what happens is that the mixture is igniting while the piston is already on its way down. So you would have to take kickstart pedal or left pedal of. Then you remove the cover. There are 3 bolts holding it in place. When the cover is off, you can see the flywheel. You need to unscrew the nut and take the flywheel off with a flywheel puller. When that's off, you can see the coil. To the left are 2 lines and on the coil is a dent. You need to losen up 2 little bolts that are holding the coil in place. Then rotate the coil to where the dent lines up with the upper line. Then, put everything back together and test your bike. The spark plug is now sparking sooner so the mixture will ignite when the piston is at the highest point.

damn dude thanks a lot! Just waiting for the flywheel remove piece to arrive already! Really detailed and helpfull response, i appreciate it! I feel my bike wants to go much faster than it actually can right now, when i get to 25-30km/h it makes a sudden restriction noise that im dreaming of eliminating hehe

@@K405X no problem man! I don't know if you have the flywheel nut off already but the easy way to do that is with a impact wrench. Just vrrrrrttt and it's off. No piston stop needed.

Hey man!! Back after some days! So, ignition is set to upper mark now, and changed the exhaust from stock to a biturbo... The ignition is exactly in the upper mark, but now after these 2 changes bike isnt working correctly, a lot of throttle delay and really tough idle... Was told changing the exhaust changed the air/fuel mix and now its to lean, so, tried all sizes of jets trying to stabilize but still nothing... Everything else is still stock, with 6000km old! (also some small grinding in cylinder+manifold by a mechanic)

Should i go back a few mm with the ignition set?

dave g youncan also buy 70cc heats if you can’t machine a head yourself

6mm x 1.0

Trial and error, years of experience... or ask a wiseman on moped-army

What brand do you have?

Great starter bike! Easy to find (lots of them for sale). parts are available online... performance parts too (at good prices). Simple bike that doesn’t need special tools to fix. All great reasons

2005 Adly sliver for 2strock what can I do to make it brake 33 MPH

The cylinder upgrades never became a problem in our past, nor the present. We do the upgrades all the time. We have both Facebook and insta @second_stroke

It’s very gray, but overlooked for the most part

He’s still around. Just bought a brand new moped from us. One of the exotic TOMOS we imported. Should see him in an episode soon.

@@MopedProblems hell yea man thats sick!!!!!!

For what moped? Make and model?

Moped Problems do they sell kits for the roughhouse 50?

@@MopedProblems for a tomos sprint a 35 engine year 2000

Nah it’s fine. It’s only 15cc

@@MopedProblems ok😁

Thread locker has no place on the top end. The block gets hot enough to make it useless. Additionally any follow up service can lead to poor torquing because of old thread lock creates faux resistance. A torque wrench proper would be a good idea. 10-12 pounds per square inch, but most people don’t have this tool. “Moped tight” is what we use in the industry.

@@MopedProblems I've ruined many cylinders, mounting hardware, and cylinder studs learning "moped tight". I def know what you mean with the residual threadlocker making it feel snug when it shouldn't. Thank you for the solid advice you got yourself a subscriber:)

This lathe gets put to good use and loves her life!

i love to see a old southbend used i just restored mine hate to see one in the tough shape @@MopedProblems

Thankfully there aren’t many Jawas in NYC. Total junk.

Goes for all mopeds! A puch moped shouldn't cost $2000. It's a moped.

A lot of people are very passionate about mopeds and it's their Hobby usually price comes with demand out here in Arizona you could get a moped for about for $500 I just saw a 77 peugot I was thinking about getting for 400 something. In New York it's so much more congested so the want for mopeds is higher

Blue Mountain Edward, i dont like your tone buddy!

those mopeds sucked long before the '80's

Kippenkop Kuikenei gekwetst?

Sucked? Those things went ! 60cc 6 port on it 17mm carb on it and a good exhaust . Mix ur own premix 34:1 with good oil !👍

It’s an important move if you admire longevity. After time and time again seeing blown head gaskets, we require this technique on all installations with an unused de-comp valve. Doing so has saved our customers money, preventing a blown head gasket the following year.

I have too. Its leaking like hell, it wont idle.

Yes, blocking the decomp hole will save you from this frustration!

What size tap did you use??

Works pretty good though. Solder test on the squish band will let you know if you gone too far
