Tip & How-To about Motorcycles
Too often intake manifolds leak, causing frustrating tuning and is bad for the engine if not fixed. Usually the cause is unseen and unknown and we plough on trying to set the tuning to no avail.
Quite often with round rubber manifolds the clamps themselves are the problem.
A bent, kinked or distorted clamp will not pull tight on the entire surface and subsequently leak. They can bend and kink quite easily when taking off stuck rubber manifolds or when levers are used.
An easy fix that saves a trip to the store is to lightly pean back into shape over a hard curved surface. Use quite a lot of small taps with a striker in a systematic process along the entire length of the band.
Do not straighten the kink near the screw flange as it accommodates the trailing end of the clamp band as you tighten.
