Dirt Bike FAQ

A good pre ride tip is to spray under your mud guards with wd40 or similar,this will help mud and dirt come off easier. you can buy an exhaust plug that fits in the end of your muffler to prevent water getting in. leave the chain on until you have finished washing the bike.high pressure are fine to use just avoid directly spraying around wheel bearings and swing arm pivots. i use cheep degreaser on the chain and back rim and any car wash for the rest of the bike.
when your done and the bike is clean and dry i use a spry on furniture polish on all the plastics, it will help to keep them looking new and make them easier to clean.then remove the chain wipe it clean and dry with a rag then hang it somewhere warm and spray it with chain wax,while you let it hang for a bit remove your air cleaner and wash it,dry it and re oil it.re fit the chain and adjust it. a quick spray around all the pivots like foot pegs with wd 40 or similar, and your good to go again.

" Whic ….. h dirt bike do I recommend? "

The one that your Mommy and Daddy will buy you.

Ask them for the cheque book first.

Like i said before get a 125
yz, cr, rm etc
i like the yz that i have
they are the fastest bikes in that class and they are made ready to race.
put some new pro circuit pipes on it and vForce reed valves and that thing will be a killer on the track
they are ALOT cheaper to fix and to maintain than 4 strokes.
the parts are really cheap too.
you could spend over 2000 on a blown up 4 stroke motor.
and less than 800 on a 2 stroke.
i would get the cr125 sice you want a honda these are great too my friend has one and they have awesome stock supension.
good luck

That's because the price would vary very much depending on condition and possible origin of the bike and documentation.

for example if it is in running condition and complete. and you are near a track that has vintage racing or contact a vintage racing club. you may have a small fortune there..

You can change the sprockets to gear it up for more top end speed but you will sacrifice low end power doing so. along with the jet kit you should be looking at air box mods for better air flow, aftermarket header pipe and muffler possibly an aftermarket cam. but then again why not just spend all that extra money on a bigger bike?

Ok, most def a 125 is too small for you, 250cc is about what you need, If your looking for speed get a 2 stroke engine with a power band and a jetted carb. If your just looking for something to ride casually and you don't want to show-off on it, get a stock 4 stroke.

Two-stroke engines have the potential for about twice the power in the same size because there are twice as many power strokes per revolution.

I'f your just starting out riding dirtbikes and don't know how very well DO NOT GET A 2 STROKE.
Start out with a 4 stroke or you might kill yourself, fast dirbikes are very dangerous, I know from experience.

other than that a 125 is too small for you, I have a 250 and I'm 5'8'' 155lbs.

There is a lot of controversy surrounding this subject. I can say that I do not know a single racer that breaks their bike in "by the book", or owners manual in this case. You should read this article and draw your own conclusion, but this is the way all of us racers do it…

I'd try to get him down to 800. but I would look for a 125 instead. you'll grow out of a 80 faster

Why don't you have it rebuilt. powroll in
oregon has a lot of go fast goodies
for the xr100. just because it was raced
does not mean you need to replace the
complete engine.

Way more trouble than it is worth.
requires:

Modification of the charging system and connection of a battery.
Wiring of lights, head+hi-lo, brake ,tail ,marker and turn lights and all the switches that go with them including a breaker panel or fuse box.
Street legal exhaust and appropriate engine de-tuning.
Street legal tires ( Knobs are no street legal)
A key ignition.
In most states ,fender height on MX bikes are too high and need to be lowered.

And there is no "Cheating" because the bike will have to pass a physical inspection before it is licensed .

I've done a couple, A Honda XR500 and a Yamaha IT425.

Even though it's not what you want to hear ,my advice is to get a dual purpose and "trick it out" rather than trying to make a MX bike street legal.
