Yes Dirt Bikes Have Vin Numbers.

Ask someone at the reference desk of your local public library for the Occupational Outlook Handbook. It lists all kinds of information you would need to know,(including the salary) of just about any occupation you can think of.

KTM recommends 1.35 L of Motorex Power Synt 4T 10W50.

you should look on the fram of the bike right in front of the gas tand on the side and it should tell u. 1977 250 YZ250D 1W3-000101 6520 NOTE: This Is The First Year Of The Plastic Tank, Used On All Bikes Except The YZ80, YZ100. It Was Also A Completely Different Frame/Monoshock/Engine Design For The 125/250/400 Models. Bob (Hurricane) Hannah Raced An Almost Completely Stock YZ250D In His Sucessful 1977 Season. From this very helpful YZ identification web site. Hope this helps http://craigmac215.tripod.com/yzmodels.htm

It could be anywhere from $250 to $450.

top speed of a yz125 in mph

If your bike starts up and runs great, but then shuts down, it is missing one of the following items: fuel, air or spark. Is your air filter installed properly and is your airbox clean? Did you leave a rag in the airbox by mistake? Don't be embarassed. I have too. If it shuts down five or ten minutes in, I would guess that one of the jets is clogged in the carb. First thing to check: Is fuel flowing freely from the gas tank? Is it possible that some dirt fell into the tank while fueling and is stopping up the fuel hole from the inside? If fuel is flowing freely, run the bike again until it dies and then drain the float bowl in the bottom of the carb with the large nut on the bottom. If fuel flows out, that would indicate that the high speed jet is clogged and needed to be blown out with compressed air. If no fuel flows, somewhere between the petcock and carbs, there is something clogging the line. Get some carb cleaner and dismantle the carb. Keep all the pieces in an ice cube tray and really give them a good once over with a toothbrush. Each jet will need to be blown out to ensure it is working properly. You should check your vent hoses at this time as well, and make sure they are routed properly so they are breathing correctly. Hope this helps. The year of your bike isn't listed, so this is shooting from the hip...

It tops out at about 65-70.

I have a 1996 Banshee that I recently started dropping a little money into. Really just to make it more competitive with the new famed 4 strokes, mostly 450R's and Suzuki Quadracer 450S. Everything else I pretty much beat, except Outlaws... When I got the Banshee it was completely stock as far as I know. Im positive the bore and everything was, the only possible thing that wasnt was jets, but not likely. When first put on the dyno, stock, it made right at 35 horsepower. Shortly after I took the ugly black stock pipes and silencers off, added ProCurcuit platinum pipes and silencers, a jetkit and boost bottle and it jumped up to 42 horsepower. These things thrive off small bolt-on mods like this. A few months later I was bored with it again, so I added Boyesen Stage 2 reeds, stage 3 jets, 4 Mil Hotcams crank, and bought a .40 over piston kit from wiseco. A few other small things not worth mentioning and suddenly this thing has torque, which Banshees are notorious for not having on low end! Now my old beater Shee, which isn't quite a beater anymore, makes over 60 horsepower and has neck snapping torque even on the low end every time you twist the throttle, yes twist. I added Elkin suspension and this thing runs rings around the new little 4stroke thumpers. My riding buddy has an 06 Raptor 700, bored to a 740cc i believe, full exhaust, sprocket swaps and stage 2 cams, I blow him out every time he decides to lay on his throttle :) Since it now has more than tolerable handling with the elkin complete kit (+2 arms, Wider axle and improved piggyback shocks, go take a look at Elkin products) its not just a straight line bullet. So if youre asking about stock horsepower, around 35 horsepower is your answer. Slightly modded with no engine tearing down (common bolt-ons) 40-45HP. But the possibilities for these things are endless if you have the money, ive seen dune shees go upwards of 100HP when you add longer stroke crankshafts, new heads for example cheetah cub, alcohol and so on.... and of course the crazy 600CC sportbike engine swap! 125-160HP!! I have always, and probably always will be for as long as they allow me, be a 2 stroke nut. That's all I've had as far as ATV's go and I love them. Yes I've ridden the new era 4 strokes, and theyre just not my cup of tea. Ill stick to my 88' 250R, 2 blasters (highly modded) and my beloved Banshee :) Theres nothing like that 2 stroke sound and ungodly powerband. Hope this helps.

it was a 4 stroke

20 parts oil to 1 gallon of gasoline 20:1

No. Alcohol consumption in the parking lot is illegal. AMC 7.16.010.010.

A 2 stroke.

Hockey. It has been proven that Motocross ranks 2nd behind Soccer, in the most strenuous sport. Skating and handling a puck is hard but, handling, balancing, controlling, and throwing around a 240lb bike, and your body weight for over a 1/2 hour, non-stop, no rest, no substitutes, etc., it would be Motocross hands down.

Would need to know what year of the 70's you are referring to. In the 70's riders changed numbers each year dependent upon how they finished the preceding season.

it appends on the bikes model

From what I know, he broke 60 bones.

my 1998 CR250 takes .79 of a quart of 10-40 oil. Hope that helps.

that vin number decodes a 1978 RM125C.


RM125C RM125-61851 to 84328 frame
RM125-62013 to 84644engine

You might be able to see or meet him at a Motocross track, but he keeps his phone and address private.

As far as i know, yz 125's are built primarily for riders 140-180 pounds, so you could say the normal wieght is 160 pounds. However, heavier or lightersprings can be used to drastically increase this range. With aftermarket springsthe acceptablewieght could be 120-200 pounds. To little or too much wieght will be a dis-advantage on the track.

If something else is wrong. My chain slipped and went through the crank case and destroyed the engine. But it was old. I've heard of this happening on other Yamaha's, so maybe their timing chains need to be replace sooner. not sure
