Dirt Bike FAQ

You dont want a mini moto mate, there chinese rubbish and break to much. either get a good brand of pitbike (terra-moto,thumpstar) or if its to rome the streets get a second hand chinese pitbike for around £200 (check your newspaper) my very first mini moto cost £175!!! which when i think now is a total rip off considering i got a genuine thumpstar for £250.

I get alot of parts from www.denniskirk.com the prices are good but depending on the bike selection could be sparse. If they don't have it check ebay.

If your going to get a street bike, get a real BMX bike. Norco makes some really good bike, but good street bikes can come cheaper and better if its street your looking for. If so, get a diamondBack Accoplice or joker. If its mountains your wanting, get a norco trails hardtail. you can use it on trails and dirt if you want. But BMX bikes are better for street.

Go bigger then a 125. for being 13 and 5'9 you can pretty much get any bike you want. your gonna grow some more so the height of a bike isn't an issue. because your age i would stay away from a 450 but maybe try like a crf250r. it has tons of power for a 250 and you won't grow out of it.

A bike doesn't need to have a 100% Chromo frame and saying it'll break because of this isn't true. When a bike is said to have a 4130 Chromo main frame they are referring to the two main (long) tubes - the top tube & down tube and the seat tube (which is the one the saddle & post are clamped into). You'll normally find the other tubes will be made from high tensile steel and this being the case it should be plenty strong enough as long as the welding is up to the job.

You'll find at this price that the components will be the bits you'll have issues with. Cheaper 3 piece cranks tend to be amongst the first parts to go. You'll often find the splines (the small grooves that hold the crank arm in place on the bottom bracket axle) will strip meaning you'll have to replace them pretty quickly. And no, before anyone pipes up - it won't be covered by warranty if you've been using the bike for jumping / park riding. Even though the bike is designed for this, it'll be excluded from the warranty cover.

Another thing you may need to think about changing pretty quickly would be the wheels. Off the peg wheels tend to be pretty poorly built. Look for something with steel rims (heavier but stronger and better braking), 48 spoke and with a serviceable hub. No point going for cartridge bearings when the wheels are going to take a kicking. And they will. especially if you're learning to jump!

Take a look at the Specialized Fuse Two & Three. Both have good frames and a good level of equipment. The Fuse Three at $400 has a full Chromo frame and slightly lighter wheels. Otherwise have a look for the GT Bump at around $300. All good places to start.

Whatever you get, don't expect it to be unbreakable. Even the really expensive ones get busted, especially if you're just getting started. Remember to save some money for pads & a helmet. And have fun!

Go to a local automotive swap meet if you want to find one cheap
used gas ones go for around $200

Are you talking moto or bicycle? I don't know of anything offhand, but here are a couple sites with classifieds and forums that you should check out and register on…if you don't see anything available, post up something and you'll probably get some replies. The Texhoma club is active and has an AWESOME riding area in Tishomingo….and they just recently hosted a national qualifier competition for trials bikes in April. Sweet! If you're in the OKC area drop me a line and I might be able to help you find a bicycle if that's your aim.

Also, if it's bicycles you're after, check out the classifieds and/or forums at http://www.observedtrials.net , http://pinkbike.com , http://www.ridemonkey.com , and http://www.mtbr.com

Hope this helps you out some. :o)

Weak spark, possibly just the spark plug .. alot of times people end up putting the wrong plug .. or you just might need a hotter plug then stock or just a new clean plug being twostrokes burn oil ..

weak compression, two strokes need to be rebuilt alot sooner then 4 strokes .. being its an 87 it might be time for an overhaul two stroke motors are pretty simple to rebuild
if compression is the case
you need to mic the cylinder to see if it needs overbored or if you can hone it
piston rings/head gasket base gasket and piston rings.. pretty cheap and somthing like 6 bolts and normal hand tools to get the head off you have no timing to mess with

and then it could be carburation .. if its running too rich it could be fouling the spark plug
if its too lean it might not be getting enough gas to start

being its a big cube two stroke it might be just how your starting it they can be tempermental

try not touching the throttle and slowly pushing the kick start down "not trying to start it" let it come back up and slowly push it down again thus priming it without flooding it

and then give it a good solid kick and barely just barely twist the throttle try that a few times …. it just might start … if it fails
try holding the throttle wide open n kicking the crap out of it … without the priming it stage before it
then you have a problem other then it just being tempermental

when it starts up .. does it run fine? if it wont idle after it gets running and cuts up at anything below 1/4th throttle it might be a cloged idle jet .. might just be a dirty carb

the list goes on and on, i would personaly start with the cheaper things, spark plug .. adjusting/cleaning the carb,

if you have a buddy with a compression gage i would test it ……….a simple way to test compression without a gage would be taking the spark plug off and holding your thumb over the plug hole pressing down .. and push the kickstart with ur hand if air blows past your thumb as u try to hold the hole closed….. you have enough compression for it to run right
