So I've had my 05 ZZR600 for almost 2 months now and in that time its went from 3900 miles to a little over 7200 right now. Now if I remember correctly we are supposed to get a valve adjustment at 7500 miles. How much does this usually run? Does it REALLY need to be done? Will I notice a difference in power or anything?

Also, I usually have to crank my bike for about 4 or 5 seconds to get it to start, or just give it a tiny bit of gas and it fires right up. Will this service help or is something else wrong? Maybe Im just a bit jealous of the FI bikes and im thinking to much about it.

Last question. A friend of mine just bought an 07 ZZR and I noticed his throttle was smooth, it felt like the FI bikes I've rode. I guess mine feels "stiffer", can this be fixed with a new throttle cable, grips, grease, anything?

Thanks guys.

It is a carb engine so giving a lil gas is normal OR just open choke up the throttle can be adjusted im pretty sure bc my mechanic did something with mine and it felt much better...

IDK bout the valve adjustment...I would have it done...but as for the 4-5 second crank w/o any throttle or choke, that's normal. It's a carb'd bike, not fuel injected so it takes a lil fuel to fire it up. Just give a little flick of the throttle when starting and it will fire right up every time pretty much instantly. And if it's the first start up of the day or for several hours, open the choke up

I asked the dealership where I bought my bike about valve adjustment and they said at 7500 miles they check the valves and adjust if nessesary. They said that most street riden bikes(if riden like your supposed to ride a STREET bike) do not need adjusted, but if riden hard would need some kind of adjustment, Since you bought yours used deffinetly have them checked and adjusted if nessesary. Proper valve adjustment would make a big diff in a bike that needs it. As for price call your dealer to find out what they charge.

my bike has 23k miles on it... valves haven't been touched. I'm sure they're a little tight, but my point is, i seriously doubt your valves will need much adjusting. But, like djones said, you should at least check the clearances to make sure.

Personally, I wouldn't trust a dealer I didn't know w/ this check... they can very easily say "oh yeah, they're outta spec" and not do a thing to change em. Either find a friend who's mechanically savvy or pick up a shop manual & do it yourself. It's not too tough of a process, just gotta do your research, follow directions & have the right tools.

its not that hard to do. the hardest part for me was measuring the clearances. it's a pain in the ass to get feeler gages down in there.
