Dirt Bike FAQ

Maybe….it would weigh less…but sound terrible.

There's no replacement for displacement. Power costs money. Bore it out and mike it bigger. Good Luck and happy trails.

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.

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.

Repeat repeat.
so it was snowing out?

Well I hate to disagree with everyone. It is true that removing the baffle will not make a big difference in power but it will help some. Honda actually published a technical bulletin explaining what they call the "Power Up Mod" for the CRF150F and CRF230F. It involves removing the baffle, modifying the air box and re-jetting the carb. Go to www.thumpertalk.com and search the CRF150F section for "power up mod" or "power up kit" for more details or just visit your local Honda dealer. They printed it off for me.

Buy a new one, they have some good stuff out!
i would say a kawasaki 80, its pretty good, but its a 3 strokes and has a lot of power, but honda has some great bikes, i stopped by there today and the 08 CRF150R was lookin good, its a 4 soo maybe u would like that? and the 08 CRF250R is pretty good too, its also has dual exhaust. but yea these bikes are made to go on hard trails, and its a honda!! sooo it will be very long lasting they make a great bike! hope u find one! good luck! and if u need more help u can ask me.

This is just one place of many that can help http://www.minibikeoutlet.com/ You can modify the engine as much as you want, like increased compression, bore it out and new exhaust, the bike rear tire can only be 10" tall and some times the front tire can be a little taller depending on the rules you run under

On new honda quads FMF performs the best also on 4 stroke dirt bikes.. Yamaha performs the best with white bros. e-series.
REMEMBER if you dont get the power kit in the carbs the pipes wont perform….

Speaking as a big guy, if you're in it for trail riding DRZ400, WR450F, or CRF450X. The last 2 are more for a racing style but a 400 4 stroke would be good, motocross ..beginner 250 2-stroke (YZ250 or CR250) mainly because they are easier to work on than a 4-stroke. I personally would not recommend a 125 2-stroke or a 250 4-stroke because of your size… lets just say the zero to 60 quotient is a high number. But the first thing I would do, new springs front and back (100 dollars an end) would be a must (like I said, speaking as a big guy, I didnt do that and I ended up w/ a decent wreck) and maybe a taller seat, lower pegs and a highbend handlebar. If you get the 2-stroke and you are a beginner, I'd either get a bigger flywheel or get a bike w/ not much of a power hit. You could get an exhaust pipe that controls that (FMF Gnarly w/ Turbine Core 2 of Q2 silencer). 4-Strokes dont have that much of a hit but are really torquey, the trade off is that they are hard to work on but now are much easier to find aftermarket parts for because thats the way the industry is going. With any bike you get, buy a Clymer service manual, trust me, its a must. Hope this helps

Check your oil/fuel mixture, drain the gas and put new fuel in it you have to much oil in it
