Motorcycle Forum / Country Specific / UK Group / August 2007ZZR1100 balancer shaft
Took the Zed in for some tyres & a few other bits doing, the chap told me the carbs need balancing by ear! I thought it had a slightly noisy cam chain tensioner, he reckons it isn't that but more than likely a balancer shaft that needs adjustment as they get left. I haven't heard of this before, is he right? Ta Nige We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Nige" <nigel.inceGETAWAY@btinternet.com> saying something like: >Took the Zed in for some tyres & a few other bits doing, the chap told >me the carbs need balancing by ear!

I suspect he means the carb actuating shaft that goes across the carb bank hasn't been slackened off properly when the carbs were last balanced, if ever. Whatever; balancing them with gauges and the shaft slackened off is the proper way to do it - doing it by ear is a bodge, a bodge that can be successful, but not proper. When the carbs are slightly out at tickover, you get a bit of lumpy running which makes the engine internals lash back and forwards a bit, especially the primary gear, leading to sounds that make you think there's something seriously wrong inside. Quite a few bikes have been bought by astute mechanics for much less then they were really worth by pointing out the horrible noises coming from the crankcase, which were easily fixed by a proper carb balance later.

Ta, i meant he could tell the carbs were out by ear, he is a bloody good mechanic & would use the right tools. Thanks for the reply.

I've never heard of *anyone* being able to balance a four's carbs by ear. Sorry. As for the engine balancer shaft, it's gear driven and needs no adjustment whatsoever. I hate to shatter your illusions, but I think your ace mechanic is a prat.

I think Nige meant that the bloke could tell by ear that the carbs needed balancing, not that he could do the job by ear. I have no idea if that's possible, just my interpretation.

So what's this 'balancer shaft' stuff?

Yes, he's right and this thread is full of people talking bollocks. If you look at the lower right side of the engine, just below where the crankshaft is you'll see the end of a slotted shaft, locked in place by a small lever. This is the balancer shaft. This shaft's housing is excentric and turning it you can remove the play in the gears that drive the balancer. In the parts diagram in www.buykawasaki.com the parts are under "balancer" with references 13618 and 13234. I suggest to replace the oil seal 92049, it has the nasty habit of leaking oil when disturbed. Difficult to source except OEM. Its dimensions are 27x19x5. I don't have the adjust procedure at hand but it's something like warm the engine, run it at some speed, unlock the shaft, turn it to some initial position and turn it back a bit until the noise is gone, lock it again. If you need it I can chase the manteinance manual and email you a pic of the relevant page. >> Took the Zed in for some tyres & a few other bits doing, the chap >> told me the carbs need balancing by ear!
