No clearance issues with the fan assemblies then.
On the Sprint, the rubber rear weather seals had to be cut for the fans to protrude. Turn the key on and it sounded like the main cooling fan had switched on, only slightly quieter. The lighting looked brilliant coming at observers but was clearly worse when riding the bike.
Low beams actually had a smaller pattern afterwards and the high beam still didn't project a discernible pattern. Triumph dropped the ball with that projector design and went back to H7 reflectors on the next design (Sprint GT). When reverting back to the H7 halogens, a new set of weather seals with the intermediate wiring harness built in was $41 plus tax (whew!).
