I have a working-solution that utilizes the stock air box!
It works with a stock paper air filter, K&N KA-1600, (probably others)...so there is NO ADDITIONAL FILTER COST (NO compromise to engine protection), as with totally exposed pod-filters.

When applied on my KZ1100A-2, the engine-performance increase is beyond my expectation.
The thing is so simple it (still) rattles my mind. There is no need to modify anything, except just disregard the sticker "obstruction warning" label on the gas tank.

Now what? I just wonder if anyone might have an idea how I might (best) market this thing. I'm thinking of calling it RETRO-FLOW, since it is designed to work on these old(er) 80's Kaw/airbox bikes.

Dear P21,

How difficult is it to access your bike's airbox to change the filter?
Would it be possible to post a picture (with the seat up) of the airbox/snorkel cover, showing part of the gas tank in the shot? But only if not too much trouble...
My email: co-des@sbcglobal.net


I am considering marketing something on ebay that will adapt to the airbox, and allow a substantial increase of un-restricted airflow to the engine, thereby enhancing power and performance...without sacrificing the functionality (and simplicity) of the stock air system.

Thanks,

Problem with bikes is that substantially increasing airflow will not always result in more power or performance, unless you also have the way to change the jetting and needle taper to match the new flow characteristics.

I found out (the hard way) that even very minor changes from year to year have big effects. I got a new set of carb slides for my "79 750 twin Mikuni BS-38 carbs..... except they were from the next year after and the slides/needles had been slightly tweaked and they ran TERRIBLE in mine. Surprising how a small change can have such a big effect.

Remember the old hot rod cars with air cleaner covers turned upside-down? A pic of one of those to head my KZ1000 KZ1100 ebay listing...might get some attention.
Thanks!

I understand that tuning is critical, but not much is being done in this case. It's primarily for a stock, original carb and exhaust system bike, like mine.
One might consider my idea a very-minor modification, but with exponential return on investment.

Yeah, I started hot rodding back in the 60's. The thing was, those engines (carburetored) were so restricted at intake and exhaust that doing almost anything to reduce backpressure or intake restriction increased power. Motorcycles are the opposite: they are so finely tuned to deliver power across the full RPM band that most any change will screw something up.Even the "performance" headers which do increase power a bit do it at the expense of low end power and torque. Increasing airflow into the intake can give more peak HP, assuming you can rich up the jetting enough to balance it. That's why pods are good for racing, but changing the intake flow might give a higher peak but not have as much at lower RPMs. It would be good to see a before and after dyno plot. If you really found a mod that will increase power across the band, bike makers will pay big money for it.
