1996 cb500 Twin - Pod filter airbox

thingiverse

I've been converting my CB500 into a cafe Racer during lockdown. I wanted to put pod filters on the carbs, but trying to maintain a constant velocity under acceleration is a real sod when you just plonk pods on the carbs. Looking at the OEM airbox, the two carbs pull air through the filter via a tube inside that is appx 56mm into a small secondary chamber shared by both carbs. Main inlet to the filter is appx 45mm. Designed and split into component parts to aid 3d printing. This WIP design will be used once the engine is back in one piece to optimise the use of one pod filter via a flow limiting joint collar.
