does an open air filter realy do anything? i know in the world of cars open filters and exhausts add bhp but do they do anything on a scoot? just seems hard work and expencive for not much gain.
-
Yes!! An open air filter, along with carb tuning, is the best "engine" mod you can do!...
..expensive??..you can do the whole thing for about $40.00..
-
sorry i ment exspencive with exhaust. i ask because every one is getting about 40 to 45 mph derestricted. so what will open filter and corect jetting make . or is it more accelerate speed?
-
..oem exhaust will work fine..
..yup, makes scoot more responsive...
-
mmmmmm ok so sounds like the next job then. whats a good filter and round about what size jet should i try?
-
..oem exhaust will work fine..

I have to slightly disagree :-\
Tbh i cant say i got much, if any, difference apart from the noise. Took me ages and a lot of jets and new plugs to get it set up perfect, which it is now, but i cant feel any real noticable improvement, certainly didnt get a "wow" factor from it that i hoped and i run with a Leo Vince too. If anything i maybe gained a little acceleration and it feels very slightly better from 25-35 but nothing to write home about for me, and it could all be in my head cos it sounds more sporty.
Main reason i left it on was just cos it looked nicer and cleaner than the huge plastic stock air box. Be prepared for lots of trial and error and swapping of jets to be sure its running not too rich or lean. If you have the time and patience to get the jetting correct and prefer the clean look then go for it, if you expect a big imrovement tho i wouldnt bother. Dont think these 4-strokes really benefit much at all from it myself.
Also be prepared for issues in the wet unless you fab up a cover for it. The one i got had a rain cover over it but i still broke down this week in heavy rain, had to end up cutting up a coke bottle and using that as a cover to get home, worked well tho so im still using that till i can make a decent cover up.
It aint pretty but it works :D

..i knew you were going to say that!!
;D
..eveery scoot does respond differently to equal levels of mods...
..for me, the K&N opened my a50 up..acceleration was quicker, and i gained top speed...
..i didn't have any great trouble jetting, tho...so the frustration level was waaayyy lower...
:o

lol see this is what all these threds say some people say yes, some say no. and as for the bad weather and rain efecting the proformance of the filter. i live in the uk. lol always rain.

Im in Glasgow, so im used to riding in the rain too :D

No you didnt :D
Think a lot of it has to do with our climates, here it varies day to day so perfect jetting one day can be just a tad too rich the next. Thinkihave the best balance i can get on the 92 main jet. I will say since i took off the plastic cover that came with it and fitted my own temp creation it does seem to rev a little higher now so maybe the old cover was resrtricing the airflow a little. I was even thinking of going up 0.2g on my rollers on the way home tonight so i may try that soon. On holiday Fri so be away for a week, maybe try it once im back. I may just be over the ideal powerband.

streido what setup are you on and what are you getting out of your scoot.
as you have sim climate as my self what have you found that works?

streido what setup are you on and what are you getting out of your scoot.

2008 model, 22,500km on it, new stock belt, race variator with 5.1g rollers, shortened smooth boss (36.8mm instead of 38m long), stock clutch with drilled out bell, 1500rpm torque/contra spring, 1500rpm clutch fly springs, 92 main jet, k&n type filter.
Gets me beat good acceleration right thro, on wet days 42mph flats, 45-48mph downhill, 30-35mph uphill. On dry days 45-48mph on flats, 50-52mph downhill, 30-40mph uphills, unless its a monster hill then it will drop to 25-30mph up it.
Recently a few people have said below 6g is too light on 2011-2012 A50's. Far as i know Kymco didnt change anything so i dont know......cant speak for them, all i know is what worked/works for me.
-
..yeah streido bro..i did.. ;D ...when i was typing it i said to myself, "Self, streido aint gonna go for this...."
..i think you and skippy will have similar results...
:o
..take skippy uinder your wing...lol...

we have lots of rain here so I'll stick to OEM....
-
..yeah streido bro..i did.. ;D ...when i was typing it i said to myself, "Self, streido aint gonna go for this
:D i def think it does now revs better now ive had a few days running with the original cover off the filter, mine must be better ;D
I can see how you say it opens it up, it does kinda feel like it breathes a little better. Again tho this could all be my imagination :-\
Vivo, youre just a big OEM girly. ;D

Pretty damn funny tho... Dr. No...

stock belt. so you havent gone to changing to a longer belt, for more top end? what manufacture is best for belts?
also how did you shorten the boss?
-
I used to run a Malossi kevlar belt at 736mm long on a normal smooth boss but i get the same top end with a stock belt and shaved boss so i use that now. I found i got slightly better take off with the shorter boss and stock belt than i got with the longer belt.
I took my boss into work and did it on a lathe, it has to be bang on or you may get a wobble.
I like Nakura belts or Bando, not the cheapest one, they do a standard and a better quality one, i got the better one. Apart from the take off i prefer them cos they are a good tenner cheaper than the Malossi Kevlars.
-
Vivo, youre just a big OEM girly. Grin
Yup! that's what I am... ;D ;D ;D Everything OEM and cruise daily at 30mph... I'm not planning on more speed but years for my scoot... ;) For speed, I got a 1981 Mitsubishi Lancer, going to do an engine swap with a 4g63 engine, bolt on a pair of Webers, do some tuning, and do some 360's....if my age permits ;D It's a joint project with my son. ;) Come to think of it, this Hot Roddin' is still OEM! Lol!

now thats a toy. forget project fuelinjection.... ;D

..this was a fun project!..
:D

Aha, the forced air induction project !!
Finding that through google (looking for ideas on supercharging) was how I came to this forum !!
-
Every mod that will require upjetting is an improvement in the air flow and more fuel fully burned is more power. But the power increase in such a little scooter engine are so little, that it for some will be more placebo effect than real kilowatts in your output. ;)
The stock air filter uses not only the actual filter to remove dust from the air, but also the change in air speed and pressure will force the dust, small air stones and water droplets to settle before going through the filter. Most open filters dont filter anything like this and many people dont use filter oil, which many of these filters need to catch the small particles.
Fitting an open filter will reduce the life of your engine, but if you really want the power increase, go with a K&N filter, as these are the ones who filter the best and still letting as much air as possible enter. :)
Good Luck ;D
-
so thats some for yes and some for no. on whether the open air filter works on a 50cc.
im still open to opinions. my mind not yet made up lol.
-
+1 on the K&N...
...and skippy, every scoot, as well as every tuner is different...

It will work and it will add power, yes. But not alot.
It's more a question if you like the looks, the sounds and if you yourself think that you can feel it. When i tried a powerfilter on my first agility i loved the way it looked over the standart filter and the sound were much more brutal (like it was mad at someone ??? ) but when i timed the accelleration it were not really any faster. The difference were around the same as the difference between sitting straight or laying over the handlebars. And i still couldnt do a wheelie or burn rubber (with both wheels on the ground). :)

lol its a 50cc if you burnt rubber its because you were fell of the bike with nothing on but a condom.

I know, it were just to say that you wont get sky high torque increase from doing this. ;)
