HD 200 air filter
« on: November 27, 2012, 09:37:10 PM »
$24.95 plus shipping, out of stock?   I don't have the time or patience to mess with that crap.

After the last couple of off road excursions, the HD 200's air filter was dirty.  Real dirty,  I should have changed it sooner :-[

Of course getting any parts for a SYM is never simple.   Instead of wasting time online trying to find one, I made a quick trip down to the local auto parts store instead.

Fram ca8602 cost $12.99 and will make four filters for the HD 200.   That's $3.25 apiece and about 2 minutes of cutting if you're slow.  First you have to remove all of the OEM paper filter and the little plastic tabs.  I smoothed everything out with a dremel and then some sandpaper.  Added a few strips of gorilla tape to make sure the custom cut air filter fit very snugly in the now empty OEM air filter frame.  The rubber edge keeps the custom filter securely in place, and the air box lid clamps down on the front part of the rubber edge tightly without impeding air flow.  

After modifying the OEM filter frame, you don't even have to remove it to replace it again.  Just pop off the air box lid and remove the custom filter and slide/wiggle another one in.

sorry this is slightly blurry




My filter frame is trimmed down on the top edge to allow more air flow from the snorkel opening to the actual filter.  I've also replaced the OEM snorkel with a larger diameter one that pulls fresh air in, not from underneath the seat next to the plastic bucket.  No doubt that will contribute to more dirt being pulled into the air filter, but at $3.25 each I'll just make sure to change it more often ;)  It works very well with my stainless steel exhaust and a mild re-jet.

Here you go ;D



The custom tube is about 25% larger in diameter (not a huge difference) and draws cooler air from under the fender, not up by the seat box.

I think the biggest improvement is where the top edge of the air filter bracket is trimmed down.  This was definitely a bottleneck for air flow, very restrictive.

Thanks for that.Having just bought a used HD 200 with 10000 klms I discovered the filter was filthy (no surprise really) and was wondering if a larger filter could be cut down.
Now I know ;  )

I'm a noob. Just took delivery of my bike and have not examined the filter setup but I have a question RE the snorkel tube: Wouldn't the intake near the top of the fender pick up a lot of shmoot thrown up as the tire rotates?

Just askin'

Yes ,that is why they have the filter box like cars do. 4wd owners often put those K&N filters on 4wds and the debris that gets thrown around by the fan clogs them up pretty quick,so the same thing will happen on a scooter.Maybe to a lesser extent.
It all depends if you want to sacrifice filter change time for another half a HP

I just bought microguard mga8602 at O'reillys for $11.99 plus tax. Fram filters in short supply. Did the modification. Really happy with the results. Haven't messed with the intake tube.     Thanks, Gitsum!

I will have to check my filter, once I figure out how to open it up. Good tips, I will bookmark this.
