I've riden a honda 85 before i couldnt even kick start it my leg was so squished. And i'm not going to get a z 400 i just used it to compare bikes and quads because it wasa a zuki site. I'll probably get a raptor 350 or blaster. 300ex's are ugly.
Well I guess i should try crack cause I don't think the Z400 would be too much bike. I consider it entry level with a little room for growth.

Keep in mind though he's 13. I mean, you're right--a Z is manageable---my girl rides mine (slowly mind you) and she's 5'4 115lbs and doesn't have a lick of experience but she's also afraid of getting hurt---something that never crossed my mind unitl i was 23 or so! hahahahhaha...seriously though i think the best thing for someone new to the sport is to shop around for a good used bike / quad, ride the p!ss out of it, and then "graduate" to something bigger and faster. Besides if he gets a Z then what does he have to look forward to? Not a whole lot of quads i'd rather have...

Get the Z400 and you will save money in the long run. Take it easy and respect the machine, until you are coinfident with your quad. Even then always be aware that anything can happen. I dont consider it an entry level quad for a 13-14 y/o, but I think with enough common sense and good judgement one can handle it. Then when you get older, and more used to the machine, you can start adding mods for more power.

I agree, I think it is managable enough for a newb, but also advanced enogh performance wise for any esperienced ride to have fun. Not to mention the Z400's are almos bullit proof.

I don't think there should be a age limit either, it depends on the kids maturity level and how well he/she will be supervised by the parent or guardian. I was riding a ATC250r at 8! But that was under the supervision of my dad too, not to mention it was just back yard riding.

Thanks Mr Dumbass and motox. This is what i'm talking about. I have a lot of common sense and my parents and other people are always telling me how mature i am for my age. I think i can handle it. I will take it easy until i feel confident and feel like i can take it up another gear. As for supervision my dad will be riding with me mostly all the time. Thanks again guys. Will get for x mas. Can't wait!

Motox, Mr.Dumass---you guys seem to know quite a bit---I need some jetting advice for my 03 Z---I've got a HMF slip on on the way that comes with the "required jets" (whatever that means). I've done some looking around on other sites and no one seems to agree on anything so here goes:

i'm going to be using the stock mikuni carb, HMF slip on, UNI filter, and EHS lid (open airbox). I've read that anything 150 to 170 mikuni jet (main) and 25 pilot will work. I'm at about a 900ft elevation. Any advice????

Thanks guys...

While I'm leaning towards the higher end 160-170, nobody can tell you exactly which jet to use. Your bike should dictate that. And unfortunately, that means trial and error. I prefer the seat of the pants approach. Does it run better or worse? Don't forget to richen the needle too.

I haven't received my pipe yet so i've haven't had a chance to tinker with it, but from everything I've read you're right when you say it's all a matter of trial and error. In the past I've just slapped a pipe on a rode, but with the Z i'd like to get into some carb tuning. Now, when you say richen the needle are you talking about adjusting the A/F screw?

No, the carb actually consists of 3 jets, pilot, needle and main. You don't have to switch out the pilot. A lot of people do to assist with cold weather starts. You can probably just come out on the fuel screw (around 1/4-3/4 turn) if you don't want to mess with it. The needle jet reminds me of a miniture lance (things knights used to joust with).You'll move the clip towards the long tapered end 1 notch. Usually you can access the main through the bottom of the carb. This make s trial and error a little less painful. Just run the gas out and switch the main. I'd start with the 170 and work my way back. Rich usually is a little less responsive when you punch it or it cuts out. Come down until you get a snappy throttle response. If you can't tell the difference, go a little rich.

EP, Raptorlegs has given you some good advice. Make sure the EHS lid is on before you jet it, that will have an effect on it, some type of high flow lid is a must on the Z400's.

And you will more than likely need a aftermarket needle. The stock one only has one groove for the clip.


As for what I did with my Z, I added a slip-on, uni filter, and high flow lid. I left my pilot stock, put the clip on the needle 2 or 3 positions up from the tapered in, and I believe my main jet was a 160.


The Z's are real finicky when it comes to jetting, so don't get frustrated. What I had should get you in the ball park, but your elevation is probably different not to mention each bike is slightly different.
