A good point Doug. An ‘inch’ might be a bit gung-ho but my horizontal portion does look like it was too long to start with. There looks to be too much length squeezes in. I will start by trying to tweak the metalwork as you suggest. I seem to has more clearance on my airbox than you have.
Jon makes a good point about temp. It’s the output from the cylinder head so probably the hottest hose in the engine reaching 100C plus.
