Air filter mod questions
11/19/16 at 14:00:03

Ok, guys I deleted my air box last night and i'm planning to do the K&N mod. Question though. Is there a big difference between the K&N pancake filter and the Ryca version. Other than a $20 price drop, and that iconic red looking K&N filter?

Also, I've read that i'm going to have to relocate my battery (I want the filter attached directly to the carburator.

Does the Pancake style offer better airflow than the cone? While i'm doing this mod is there any other mods that i need to do since i'm already here?

Worst thing you could do. The cv carb likes straight air flow.
Best to have a length as long as the stock rubber ducky.
And don't close off the eye brow port with a cheap cone filter.

So what set up would you recommend? I'm new to this so as best description as possible.

intake tuning theory

Search term

There have been some pretty interesting posts on it here.

There really is a reason why the straw that comes in a malt is bigger.

The volume of air between the filter and carb matters.

If slapping a cone filter on the carb was
Instant horsepower
Wouldn't manufacturers save the cost of the airbox?

Got a killer mid range right now !

It gives the engine something to breathe from instead of trying to constantly suck air through the filter. Much more efficient with a plenum.

Anyone thinking a cone filter mounted directly to the carb is a performance move really needs to check it out!

Thanks Batman,I have done hours of math and hours of R&D. Changing runner length ,different air filters, different jetting over & over. It's just about dialed but I have another engine mod to do and when that's done I'll be ready to settle in with a runner length & air filter that work well !
Right now it has some crazy power in mid range at peak torque.
And I can move up & down rpm range , what fun ! Thanks to all that posted !

JOG , At one point I did have a cardboard and a plastic tube , one inside the other with air filter at the end held together with electrical tape and duct taped to side of the bike,but the contraption wound up being too long even at its shortest. Found that its only a matter of 4 to 10" , I can't go any shorter than 4" due to needing a elbow to get around battery box,
RYCA battery box. From short to long or long to short,different filters affects jetting too , lots of variables , lots of time !
