Vector Cam Tensioner

[Brian W]

I took my sled in to a local dealer and was told that my cam tensioner should be replaced. The 2005 - 07 vectors have a faulty cam tensioner and the replacement is an updated design like the 2008. Is there a service or warranty bulletin that gives more info?

Brian,
Welcome to TY. You should probably sign up at www.ty4stroke.com as well (you can use the same info), the 4 stroke stuff is located there.

There is a service bulletin on the cam chain tensioner. Here is the gist of it:

The mechanical-type cam chain tensioner for the above models was changed in 2008. The tensioner was improved to reduce the possibility of insufficient cam chain tension and the resulting engine damage that could be caused by a loose cam chain. All 2008 and newer models have the new tensioner.
Inspection / Diagnosis
The symptom of loose cam chain tension is excessive rattle noise near the cam chain tensioner while the engine is running.
The damage caused by a loose cam chain tension could be engine damage due to valve/piston contact or severe wear of the cam chain drive gear on the crankshaft.
If any of the above symptoms or damage occurs, make sure the cam chain tensioner assembly is replaced with a new tensioner.
NOTE: The original failed tensioner may function properly when removed and bench tested. If the original tensioner is reinstalled, it will likely fail again causing repeat engine noise or damage.

My Father's 06 Vector GT is still silent after 10,500 KM's. If you'll feel better have it changed. If your reasonably capable of wrenching on it, there is a DIY thread about this very issue over on the 4 stroke forum.
