Hayabusa\'s are in the news again with a recall BUT not to replace the breaking subframes. Suzuki still maintains they are safe despite numerous of them breaking.
No, the recall is because Suzuki has realised that the camchain tensioners can fail. This is the second time the Hayabusa has been recalled for this problem. After failures last year they were recalled and a redesigned tensioner was fitted. However it has proved to be no better than the original and if it breaks the engines can seize. If the tensioner fails, the camchain can become loose, allowing it to jump the teeth on the cam sprockets and knock the valve timing out. As a result, the valves can hit the pistons - seizing the engine. If that happened, the rear wheel would lock.
There have been around dozen-camchain failures in the UK and many more worldwide. Several riders are blaming crashes on engine seizures caused by the failures.
The third attempt sees a new tensioner designed from scratch, this one features oil pressure as well as a spring to keep camchain tight. There is also ratchet backup fitted so that the new tensioner can\'t loosen off once it has tightened up the camchain.
Letters have already been sent out to owners informing them about the recall.
A Suzuki spokesman said owners should get the work done as quickly as possible and should not take any risks with their bikes. He said: \"This is an urgent safety recall. Owners should avoid using high revs and sharp acceleration or deceleration until the work has been done.\" The work will take around 3 and 1/2 hours.
