As many know, and have experienced, most of the time when one converts their engine to reed valve intake through the stock jug intake there is usually a loss of top end power. I converted my engine to operate on a reed valve intake at the beginning of the year and I also noticed this loss of power at the top end, but the low-mid range power picked up quite a bit.
The first two pictures show my first conversion.
The problem I had was my engine seemed to be starving on intake charge at higher RPM's which limited power and after thinking about it for some time I concluded that it had to be because of the small intake.
If you ever look at a proper reed valve engine, that's not case inducted, the intake is at the very bottom of the jug so I tried to copy this concept by cutting a big hole in my jug. Well I cut up an old jug to see if it would first.
The last three pictures are an old jug.
I also drilled and tapped holes into the jug to see if that would work too.
