The left rubber intake hose fell off the air box recently: it left a melted smear on the cylinder fins.
As it happens, the bike's been running much better recently, better fuel consumption and much better behaviour around town in heavy traffic. The hose, well, the one that's left anyway, are angled down and seem to suck hot air off the cylinders which won't help when at a standstill, I'm sure.
I've looked at various posts on the forum and can't find opinions as to what they do to benefit induction.
For example, without them, is there a ram air effect? Is this a good thing?
The cross sectional area of the aperture seems smaller than the bit they go onto: good or bad?
Do they cause poor running in traffic as I suspect?
They must have been put on for a reason - to stop crap (insects, discarded cigarette butts, small birds etc.) flying into the air box, perhaps?
So, do I lose the other one or replace the lost one?
Votes please.
