High Flow Airfilter for Stock Box

[Dandy Dan]

I went to Canadian Tire in search of the Honda or Briggs & Stratton filters to save a few $$$. They didn't have either but they did have a 'Dymax' filter that looked the right size and said it fits '3.5 - 5 HP Briggs & Stratton engines'. The difference about this filter vs. the stocker is that the stock filter has a metal back with small holes to let the air through but this one has almost a small chicken wire back so it is much more open. When i got home i tried breathing through both and the Dymax filter was way easier (some of this would be because my stocker is kinda dirty but i can't imagine that accounting for the huge difference). The Dymax filter also has slightly thinner filter paper. The Dymax filter was $6.49 Can so about $5 U.S. (verses $13.42 U.S. for the stock replacement on Ron Ayers.com). I don't know where you'd get em in the states but i'm sure somebodies got em. Oh, the part # is 60-7033-6

well i actually installed the new filter and took 'er for a test spin and the new filter definately breathes better. I'm gonna be spending the evening jetting again cuz she's running too lean.

sweet ;D

tell us how it goes. I maybe able to order some jets and get a nice cheap filter like this one for a decent performance boost!

I want that cam bad!

Abe, I think you should have a package deal, like develop the most performance enhancing pachage you can. Cam, airfilter, jetting, exhaust, cdi, drive mods, etc. Then tweak it to the max.

You could make the most optimal best performing ruckus motor. Then, we could send our motor in and for a hefty price have ours fully pimped out!

I would think that would be awesome.

I had to change my 90 jet with some tape covering 1/2 to a 95 jet that is wide open after i installed the filter. My ruckus is definately faster than ever. Everyone should open up their airbox, swap the filter and rejet. It's easy and super cheap.

That's a cool mod ;D I personally like keeping the factory air box but I wish it didn't look so lame.

I'll have to look for that filter.

So now that you have more power have you tried shorter drive spacers?


Scribb- I think people would have a heart attack if they
see the total price all at once I'm Pimpn out my Ruckus
and it's not real cheap. One thing for sure is it looks
cool and the ladies like it ;D

dandyman, could explain the entire procedure I just bought the filter at canadian tire too, cept where do you get the jets in canada? you said 95 was good? and the stock is 75? thanks for the info if you could.

[Dandy Dan]

I got my jets off of the battlescooter store. They sell a 6 pack that ranges from 75 - 100 in incriments of 5. It's 13$ but you do have to pay 25$ shipping (if abe agreed to send it buy regular mail it may be cheaper). If thats all you're gonna order maybe you should go to your local dealer and order em. In order to install the filter just take out the 5 philips head screws that hold on the airbox. Lift the old filter out and drop in the new one. At the same time i would open up the opening on the airbox. Use a jigsaw or a hacksaw blade (its easier without the handle) and cut the opening bigger. You'll see what i mean when you look in the intake. The sawing won't be visable from the outside. Open it up as much as you can. Then to swap the jets remove the seat (6, 12mm bolts) the inside cover (battery cover, 4 screws) and the floor panel (8, 10mm bolts) and you'll be looking at the carb. Loosen the 2 screws in front of the carb and the 1 behind so you can slide them off, you can take off other tubes which may make it easier but you don't have too, you just need to be able to see the bottom of the carb. Once the bottom is in sight remove the 3 screws and the bottom slides off, There's gas in there so you may want a rag. If you tilt the carb much the gas might have already spilled out.... Anyways, just take the bottom off, you'll see the jet in the middle, Unscrew it and screw in the new one. What size depends on how much you've opened the airbox, your airfilter, altitude etc. Probably a 90 - 95 will do. You can play with taping over some of the airbox opening to get the mix right. My 95 jet is running a tad rich so i may go down to 90 with some tape on it. Good luck

Abe, you need to hire dan to write for battlescooter. Dan, great explanation. Now I'm thinking I might even be able to handle this mod. ;D

Next question, but I think I'll need to start a new thread...

[tygerfifteen]

thankx dan, does it make a huge diff?
in overall speed, acceleration,horsepower,kph?
thankx again.
and since your from canada , any place to get parts here?

[Dandy Dan]

Opening up the airbox makes a much bigger difference than swapping the filter. You'll notice a big difference in both sound and power if you do both. Best of all it's a super cheap mod. If you just buy the filter and don't open up the airbox than you'll only need maybe an 80 jet. You can have mine if you send a S.A.S.E. I would really recommend opening up the airbox to though cuz it makes a way bigger difference and its so simple, just cut the hole bigger. If you need the jets in canada just go to your honda dealer. They sell em in all sizes i think. I'd grab a 90, then open up the airbox and then slowly cover the hole with tape until the mix is right. You can just time your 0 - 30 mph runs and when you're getting the lowest times then you know the mix is pretty good. You won't notice a huge diff. in top speed because the ruckus is geared too low and by 36/37mph its already past the power peak. However simply shortening the metal spacer in your variator (see tech on battlescooter.com) will gear your ride taller and boost your top speed now that you have the power to do so.

Ya, I think I need to hire Dan

I have been following the threads for the Airbox mods for some time. I love my Ruckus but sluggish just doesn't explain it. It is quite slow vs. virtually every other scooter on the road. I've been wanting to bore out the stock Airbox but was waiting to get the new Main Jet as per the specs that Dandydan etc. have said. However I'm having some issues with altitude. The Honda Parts "kid" said that the Ruckus is stock jetted for Sea Level - 5000 feet. I am at 4700 feet. He said that if you put a #95 main jet on the carb the scoot will be extremely rich no matter what is done to the Airbox. SO, my question is what would any of you recommend in terms of Jetting at this altitude if I want to bore out the Airbox and get some more power?

Thanks...

[Dandy Dan]

Try taking the airbox cover off and see if you go anywhere. You won't cuz it'll be way to lean. You'll get to maybe 3mph and then the engine will have no power. The airbox cover is majorly restrictive. With my hole wide open I'm back to the 95 jet and its running awesome. My ruckus is so much faster. At your low altitude the air should be thicker so you should have no prob. running at 90 or 95 (lower altitude = thicker air = running lean = bigger jet to remedy the problem). I live in southern Ontario and have no idea what the altitude is but i'm pretty sure i'm higher than you. The parts kid has to be wrong cuz my ruckus cruises at 41mph on flat. (with opened up airbox and CDI). The only other thing is that since i live in Canada the temp. may be a few degrees colder but i'm sure you could atleast get to a 90.

[sloagm]

Thanks for the reply Dandy D. Unfortunately I am at a much higher altitude than you. 4700 ft. Southern Ont. is anywhere from 500 to 1000 ft. So what are your thoughts on high Altitude mods?

Thanks again...

[Dandy Dan]

I'm not sure what i was thinking on the last post. I was thinking 5000 was a really low altitude....Anyways, what i would do is order the 6 pack of jets from the battlescooter store. When they come in, then open up your airbox cover and then start increasing your jet size until it runs nicely. At a high altitude you want all the air you can so if you put her wide open and even better get a higher flowing airfilter (most lawnmower filters will be better than your stocker)then you should be able to go to at least an 85 or 90. The stock airbox is meant to be restrictive so you can't go wrong opening it up.

Is there away to just modify the stock air box on a Honda ruckus cause it's my only means of transportation and I sometimes have to ride in the rain and the aftermarket air filters with take in to much water I thank

I would honestly suggest you leave it stock if it your only means of transportation due to the hit and miss nature of tuning that will come with modification. I would suggest the K&N drop in filter and to cut out the internal snorkel in your airbox cover if you do intend to keep it stock looking.
