Dirt Bike FAQ

A 125 to 150 is not really for a child. It will be tough to get something for 500.00 that is a major brand. Remember a Honda, Yamaha Kawaski, Suzuki will hold some value especially the entry level bikes. It is hard to tell you what to look for since you did not mention his size, age, and skill level.

Take new one

The common way to restrict the DT125R (& LC) is to unlink the powervalve on the lefthand side of the engine (as you sit on it), depending on what is there it could be a case of replacing a cable. You can turn the valve to the on position, while that gives you more top end the range suffers until you hit the powerband. The youtube videos show the position and operation.
Pre-powervalve DTs used a restrictive washer in the exhaust header.

Change the oil and use a motorcycle 10w-40 and just continue to use that brand after all you shouldn't mix brands or grades

For future reference, always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer.

Some aftermarket companies offer "lighting coils" for specific bikes.
A lighting coil is attached at the flywheel and produces electricity the same way as the magneto.

There are units for quads that use a small amount of power from the CDI and amplify it to operate a headlight.
Those companies would surely have kits for bikes.
But each kit is model specific.

Nope that's the price.. it's a chinese bike and they're extremely cheap…. my 200cc cost me just a bit less then 1k delivered, whereas, if i were to say of bought a yamaha, you could easily add another 6k onto that price.

the problem with them is not with the bikes, it's just finding a parts dealer…. if you can find a dealer that sells the parts, you've got no problems (i would help you, but there are like 3,000 diffrent types of chinese bikes… you gotta find a dealer that sells parts for your model, or hope like hell the part you ordered fits right.)

oh yeah, they also come partly disassembled (well most of 'em do anyways) with mine i had to put on the front wheel/fender, the handlebars, put the battery in and hook up the rear suspension… then just put gas in it, played with the idling screw to get it running right and off i went…

if you get the bike, when you get home and get it together if it won't start, or dies immediately don't fret… you need to adjust your idling screw…

careful on the new tires… they love to slip, especially on the street…. you're not on a crotch rocket so don't expect it to handle like one…. cuz if you try and pull off a tight turn right out of the box i garuntee your front wheel is going the opposite dirrection of your back wheel while you go flying off lol… i should know… it happened to me. no one warned ME about new tires.

stick to straight lines as much as possible til your tires get worn in a bit…. also take it easy on the new motor…. i know it's gonna be hard but don't go flooring it, popping wheelies or jumping it til ti's broken in a bit…

You can buy from an individual, who may or may not have taken care of his machine, or from a dealer who can stand behind what he sells. Individuals with bikes can be found at cycletrader.com and there are dealers that sell dirt bikes on every street corner. If you're planning on riding in SoCal, better think about a four-stroke instead.

As you have only the experience from riding the crf150f and are only 5ft 5 tall I think you may be better to wait till you are just a little taller before getting a 4 stroke 250cc. You would still be a good size for the crf150r or an 85cc and may be alright on a 2 stroke 125cc but think you should go sit on one at a shop before you thought about one of those. If you go for the smaller bikes you may have to be prepared to upgrade depending upon how tall you are likely to get. You can still race a crf150r and an 85cc for a couple more years. As a beginner at racing any of the known brands would be fine.

From the sound of your "blue seat" the CR80 you have must be an 80's model. Back in those days, if a "big wheel" 80 existed, it was probably a factory bike or the previous owner decided to try the larger wheel on the front because of a "new" idea.
The bigger wheel on the front makes for better turning and handling for those kids who have gotten older and larger and faster, but were not ready to move up to the 125cc class. Also, the larger wheel has a larger brake rotor, which in turn means better front brake system and better stopping power for those "faster" kids.
It's been some time since i worked for a Honda dealership, but I believe in those days the paint color was accually called "Honda Orange". I could be mistaken. Get the frame number off the steering yoke and call it in to your nearest Honda dealer to see what year the bike is if you don't know. They can also tell you the color and can order you the paint in a spray can. This color used to be available through an after market company as well such as Tucker Rockey or Parts Unlimited. As far as I know, the color is still available. Good Luck!
