Ahhhh. I stumbled upon that once before. Didn't read into it much though. Meh....

After looking at the scoot a few times, I'm definitely gonna go more tire + more low.

 

Question for all of you do it yourself tuners of the 50cc... On a 50cc engine would a bigger better carb, expansion chamber, and higher flow intake alone on an otherwise stock engine/stock gearing be able to provide a worthwhile gain in performance? I'm new to doing my own engine work/tuning.

 

Um, can you cafe this?kthnx

 

haha, thats exactly what i am going to do to it. I posted a lot of picture of these garelli's cafe'd.

Plans so far are

70cc big bore kit
exhaust
bigger carb
clip on bars
new grips and controls
maybe new seat... something more racer-ish
maybe new paint
cut front fender and remove rear

the list can go on forever

 

I really need you to meet the dude i bought my moped off of. He knows so much shit about these motors

 

Scary fun is a great way to describe it



yes, all a higher octane fuel does is not per-detinate like a lower octane fuel will. Fobangah was wrong about 87 not burning as thorough. 99% of gas is burnt in a properly running engine. So with the timing advanced, you would be better off running like 91, now if you milled the head, or put a thinner gasket on, your bumping your compression up, and that will also cause pre-detination thus either higher octane or more timing.

Im sure Fabrik8 will come in here, and punch holes all through what i just said. I think im fairly correct though.



and bmudah- technically yes, if your flowing more air and fuel, you will see some gains ( minimal) you will also need to run a ?colder? plug and have a less restrictive exhaust to get full gain of the other mods

 

Brandon. If you are running a 70cc BB kit, im pretty sure a bigger carb would work wonders for you. Just got to get some jets and tune it right

The problem I'm having with the batavus is that there is zero aftermarket support for batavus engines... So kits are a no go... So I'm sorta limited to DIY performance unless I try a whole engine swap to something like a puch or tomos where the sky is the limit as far as kits and parts go. I have found an intake that with some modification will let me run a dellorto sha 15.15 or a 16.16. As far as exhaust I'd have to make my own or modify one to work or use my stock header and add a different chamber(which I don't know how much good that would do). Milling the head is another possibility. I just don't know what direction I should be heading in to seek the gains I'm looking for... As of now it runs 35 ish with 180ish pounds of me on it. I'd love to be able to run 40-45

 

Honda Hobbits are pretty dope

Im not too good of help here. I still dont know what mopeds have good aftermarket support besides the 2 you listed lol
