Two completely different bikes. The 9 is a heavy sporty tourer, the 6 is a little revving screamer. The 9 is pretty bullet proof, but the 6 will out handle it and be easier on tires from a weight standpoint. What kind of a bike do you want? What kind of riding do you do? What's your budget? I agree with the other posters; you may just want to save your money and get something newer, unless you just like older technology and have plenty of tools.

 

I was not the biggest fan of the '91 model years bore/stroke. As mentioned above, how do you plan on setting her up and riding?

 

what's another year

 

I enjoy longer ridesso maybe the zx9

 

what are some zx9 issues for this vintage

 

I think that they are both good rides depending on what you expect and tweak the ride to do to meet your expectations. An '84 9 is going to be heavier but pretty stable. Good for those 1 week stints of cruizing

 

Weight, tire life, down on horsepower by today's measure (power to weight), it won't be a good track bike. No REAL mechanical issues. When they first came out, the tranny got some bad press due to hitting false neutrals in lower gears. I haven't experienced this; my '95 seems to shift just fine. (again, if you want a track bike or a drag bike, there are other much better options!) I run Mobil-1 in mine and have never had a clutch/tranny problem. (No; I'm NOT trying to restart an oil thread!!)
On the plus side, they're reliable as hell, excellent on longer rides (i.e. hours), pretty comfortable, still "sporty," and will put a smile on your face above 9-10K rpm. Just don't think you'll be competitive with Busa'son the straights, ornewer 600's in the twisties.

 

Whoa, I just noticed; did you mean '84 or '94? Gadz, go with the newest technology you can afford!

 

Gonna go and try the '91 ZX-6 but am reluctant due to the age and high RPMs this thing demands. I've burnt many bikes before this one. Anything to look for and can I expect to have to do regular work on it. Also it seems like this guy has not had many offers since he's brought his price from 2700 to 1400.

 

keep up on those valve adjustments!!
