It's either this or porting your stock jug. I'd say it's totally worth it if you don't feel comfortable hacking up your stock jug.

Deck your head for more compression (search about it here)

Upgrade carb and lighten the clutch and you'll have a zippy bike that probably tops out around 34-35ish.

If you weld and mount up an expansion chamber you'll hit upper 30s with big enough porting and the right gearing.

But since your bike only has one gear you have to balance between decent low end, and good high end. Bigger porting can work with the peugeot clutch, because you can make it lighter, and get back some low end even with bigger porting. Gearing is always a give and take, it just depends what kind of riding you're gonna do.

try it man it probably ur only option to ever get an aftermarket top end for that thing

okay, I am with Danny on this one, I have been looking for a solution to the slow 102 thing myself and came on this site to search for some light at the end of the tunnel, and I find this thread. YAY! I have been contemplating that part for about 2 months now, I have the money now and am almost ready to to take the jump. I am however a bit apprehensive to pull my bike apart and put this on unless I am going to notice a significant difference, I also need to find a pipe that will fit her, I didn't see anything on treats that say "102" so I am not sure what to buy, also is there anything I can get that will show me what porting is or a guide on how to do it, as I have barely taken the air filter off her so I am still a noob at this, I drive her 3 miles a day, some semi big hills, I would love for her to go over 30, but I am a big guy and need more low end performance to get her off the line rather than top speed, I don't want to peddle so much. Don't mean to take over Dan's thread or anything but any help is much appreciated! I don't have much tools or am a welder so without getting too heavy into rebuilding her.

102's still have ~39mm stroke right? I'm sure you can find some cylinder inducted scooter kit. Possible american mopeds future project.

It's an 80cc 'metrakit' that's the company. Don't need to weld, but you need some knowledge. Read up buddy. Get the manual, learn it. Check out some of the 103 threads... I think they have the same clutch.

lightening your clutch will improve your low end drastically.

The 102 is like any other moped. You can do anything with ingenuity. Stuff like deck the head, shave the piston-skirt lighten the clutch, upgrade your carb, fab an explansion chamber exhaust. You can do this shit to any moped. Look what folks have done to the Batavus-- another infamously difficult brand.

You will need a better carb and larger intake I can't tell you how to do it, but you may be able to fab something up. Maybe you can fit a dellorto 14.12 on there, maybe a moby shorty intake will fit?? Questions for you to answer for all of us.

The 50cc parmakit is like a new clean top end with larger ports than your old engine. The same gains can be had by porting the stock jug yourself. If you plan on keeping that 102 for a while, you may want to buy one just in case something happens to your stock motor.

whoa whats this about putting a poini or metra on a pug? puch have a 43mm stroke and pugs have a 39.1mm but if they have the same bolt pattern could you take 3.9mm off a puch kit and run that? or maybe get the strokercrank and mill down the spacer?
