MOPED ARMY

Barettas have minarelli engines, put a polini kit, phbd carb, and an expansion chamber exhaust on there and you will go faster than that 110cc four stroke engine. And you won't have to butcher your bike and do a bunch of welding. A 110cc 4-stroke only produces about as much horsepower as a 55cc 2-stroke, having 4 gears is cool but it will just make it a motorcycle.

I have a kitted Minarelli V1 bike from 1978 (which I didn't build), and a 110cc Lifan Honda Cub from 1967 (which I did build).

The kitted Minarelli goes thirty miles per hour up any hill (I could re-gear, but it's so fun), and the 110 Cub goes over sixty (but crawls up hills in second gear that the Minarelli would just eat).

They are very different machines, and both are fun.

Alex, the above said, I would spend your money on a new (well... used) Minarelli V1 plus some parts before buying a new Lifan motor for your bike.

Among other things, I do not think that your brakes are very good. The Lifan engine weighs A LOT more than the original Minarelli.

Also, the mounts for a Minarelli engine are almost two inches thinner than the mounts for a Lifan engine, and angled differently.

You would need brackets to account for the width difference, and to cut the frame (so as to not point your new engine straight at the ground like a pole-vaulter).

If you _really_ want to use that engine, buy a Honda cub frame - it is bigger, stronger, has bigger wheels with bigger brakes, and yet will leave you with something that still somehow seems like a fast, fun moped.

See if there's any interest in frame trades in the Buy/Sell forum - someone here might have a cub frame they're not using, and want an Italian moped thing like you've got.

well those Chinese knock offs are notoriously sucky the 110cc will do 55 but a 90cc Honda will do 55 with one less gear. to much work for little benefit and as reliable as your old 2 stroke

Ha well I do appreciate the input, no matter how selfish or greedy one can be. The fact is that the link I posted was an example. I wanted to see if it was a good idea to buy a new motor because the Franco Morini MO1 on there now is just embarassing. I am more interested in getting a kit and carb for the engine I have got, but really don't know where to begin. I just need to be pointed in the right direction....the work I can do myself, but finding the right parts is another story.

I have an old Jawa that is getting a 125cc Chinese knock-off, it too will be getting a "real" hydraulic fork, along with the front disk brake from the same source. I will be retaining the fully functioning pedals (though you will have to fold up the foot pegs to use them). So, at least in spirit, it will still be a moped.

I bought an entire bike (a so called "pit bike") for $300, and should be able to dispose of the cast-offs for about $200, making this "upgrade" cost less than a 2 stroke performance pipe.

if you are gonna slap a honda engine in it... just get a genuine honda engine, then rebuild the top end with chinese parts. so it atleast looks good.

"morini":https://www.1977mopeds.com/product/577/Imperial-Morini-M1-65cc-/ kit. don't know anything about it, but..

really the thing to do is start with a good pipe and carb and move on to the kit when you know your bike better.
