Hi Everyone, I have recently bought a Kawasaki 550 zephyr, unregistered and a little un loved with the intention of getting her on the road to do my learners. I have successfully cleaned the carbies and the bike will now run, albeit very rough and only on three cylinders (I suspect this will be rectified by balancing the carbies). Now that I have the bike running, I have noticed the engine is a little rattly. I am hoping that this is down to a worn cam chain tensioner. My Question is: am I better off just replacing with a stock auto tensioner or go for an aftermarket manual tensioner? I am a relative noob to this sort of thing, so also, is the manual option fairly easy to install and adjust to the correct tension? Any other tips pointers from other Zephyr owners would be greatly appreciated. Thanks!
