I guess it depends on how tight you can get them!
Sometimes access makes it difficult to pull them up to the max, otherwise I'd say no problems.
You only need to pinch up the sleeve to make it airtight after all....I'd try it then spray 'easy start' ether engine starter or suchlike, to identify leaks: Spray onto the throttles with the engine running, it will rev up if its drawing air/starter spray thru the ties :2thumbup:
Another test is to drip light oil onto the joints, with engine running, it will be sucked into the engine if leaking
