I am 16 years old and plan on buying a dirt bike this summer. I have been around them my hole life and I first wanted to get a kx80. I thought I would grow out of it to fast and said to myself go big or go home. I love the power and was thinking about buying a kx250 2-stroke. I am 5'8 and 150 pounds. I was wondering if it would be difficult for me to ride or not? I am pretty confidante and I don't think I will have a problem but I would like some advice.

G'day. You can acess for free an exploded diagram(parts fisch) for your bike at http://www.mrcycles.com. Go to kawasaki parts-enter year & model & away you go.
Hope this was helpfull.

Hi, had many different motos for many years..... ( Am a 42 year old Australian, biker living in China )
Firstly, why the hell are you servicing this machine SO regularly????!!!! Twice a year is ok.... I see many old bikes rolling around here that have never had a service or oil change in their entire life yet can still do a daily job, carry unimaginable loads and go at fantastic speeds. You have to let the engine and gearbox run how they like to... Don't "love" your bike to death.
Chinese bikes are not much different to Indian bikes, in fact the Indians take much technology from the Chinese, the Chinese get ALL of their technology from the Japanese...
Simple procedure....
Good fuel and a good clean, rust free fuel tank, no dirt in the fuel tank or reserve tap, then, check fuel supply and make sure fuel is reaching the carby well.... Check sparkplug and electricals, being an older Asian machine, this may be a problem.. Check carby jets as well, if they are clogged, you will have crappy performance and power...May idle well, but open the the throttle and the faster you want to go,...the slower the bike wants to go...( Different jets,,,,idle and acceleration) Oil changes should really be made around 3000 to 5000k"S, depending on your milage or use of the bike.....Even a 15 year old car can safely do 10000 k's between oil changes. I have a Chinese 2009 model 48cc scooter here, that can go for at least 280kms on a small tank of 93 octane unleaded fuel, and at times can reach 90km/h with good acceleration, sometimes with my wife on the back!.... no problem. After buying it, I just read the manual, adjusted the mixture and idle screws on the carby and off we went.

well in the good old USA if you have a 16 digit VIN number then the 10th digit will always denote the model year of the vehicle and that applies to all vehicles with a 16 digit VIN. The coding for them simply starts with the letter H and they leave out a few choice letters such as I O Q Z and then it starts into numbers after Y and honestly after the year 2009 Im not sure what they have gone to as Im not currently working in a dealership anymore, however here is a chart that I made to help ya get it figured out. Good luck and enjoy your summer.
h = 1986
j = 1987
k = 1988
l = 1989
m = 1990
n = 1991
p = 1992
r = 1993
s = 1994
t = 1995
u = 1996
v = 1997
w = 1998
x = 1999
y = 2000
1 = 2001
2 = 2002
3 = 2003
4 = 2004
5 = 2005
6 = 2006
7 = 2007
8 = 2008
9 = 2009

The first thing you need to do is to convince your caregivers,whether it's parents,grandparents,etc.that you are responsible.
This means that you should do your chores,homework,be nice to your brothers or sisters if you have any...just make sure that you do this for awhile,not for one day.
After about a month or so,sit down with mom,dad,whoever...and tell them that you really want one.
If they think you deserve to be given the chance then you could start by going to yardsales,auctions,and posting on-line for a used one.
Always start with a used one.
Trust me on this...not only am I someone's child,but I'm also someone's parent...I know how adults think.lol
If it's because of money that you can't get one then post on craigslist. You could trade someone on there for something that you have or something that you can do. Maybe some little old lady has a dirtbike in her garage and she needs a hole dug in her backyard...you could dig the hole for her and she would give you the bike.
If this is truly your passion then it will come to be. My little brother was 15 when he got his first dirtbike.He's almost 40 now,and still lives to ride and rides to live.
Good luck on your quest.

hi mate gear oil wise you need light gear oil i reccomend silkolene,motorex,morris,rock oil for 2 stroke wise you need to buy a mixing bottle of ebay or something with a ratio of 32/1 and i use silkolene comp 2 premix competition oil descent stuff its 10 pound for 1 litre

some bikes are like that. The rear wheel only spins with the pedals. Try pedaling backwards and see if the wheel goes back. If it does then that is normal.

I checked the NADA valuation book and they don't go back past 2003. A 2003 Nighthawk shows an average retail of $1590. Your bike is 16 years old. Parts will become a problem. Most dealers will not work on a bike more than 10 years old. At 14K miles there should be a lot of life left in the bike and you say it is pretty sweet. Check the cost of a new bike to what the seller wants for the old bike. Personally, I would call it a vintage bike and offer $2000.

Please rate this answer. Thanks essay1079!

The bikes are pre-assembled by a machine that overtightens the rear axle.  I had the same problem with my daugher's 12 inch huffy princess bike and my other duaghter's 16 inch Schwinn bike.  If you loosen the nuts on the back axle it fixes the problem.  I have read that the idea thing for these bike is to have them re-assembled and re-lubricated by a bike shop, but I thought this might cost as much as I paid for the bike. 

DUDE,
CALL YOUR LOCAL KAWASAKI DEALER SERVICE DEPTMENT MOST OF THE GUYS ARE VERY COOL AND WILL LOOK IT UP FOR YOU NO PROBLEM I HAVE DONE IT BEFORE IF THIS IS A BIKE YOU PLAN ON KEEPING I WOULD GO ON EBAY AND BUY A MANUAL ON DISK FOR COMPUTER THEY SELL FOR 5.95 W SHIPPING ITS A GOOD DEAL. GOOD LUCK MAN
