Have been using the hose to the ear, though how reliable is this?. Not after perfection, and mainly looking for any better economy. I do a fair bit of city driving in which my mpg is far less than when cruising (which is usual), though, I understand the lower the rpm, the more important the balance is, as the more the butterfly flaps move towards horizontal position, the air intake is more equalised anyway?, which makes sense to me?.
Also, if opinion is not positive about using the hose?, any ideas on a DIY tool to make for this please?. have googled it, though no joy.
This would be for CD150 Stroms
Cheers
