06 KTM 450 sx backfires?
Sounds lean to me. I would check these things out, make sure that the air filter is clean, put in a new plug (gapped properly), drain out the old gas in the tank and put a gallon of fresh 91 octane. Now try the bike, if it is still backfiring, I would pull the carb off and clean it thoroughly pulling the main jet, pilot jet and check what position the clip is in. I would check the owners manual for stock carb settings (if you don't have a manual get with your local KTM dealer) and adjust the carb back to stock. If you are in a higher altitude, check with your shop and see what they are running in their bikes for mj, pj and clip position.

Answer \n. \nThe 250SX is a 2 Stroke engine with a Gas (1.98 Gals Unleaded Premium 91 octane Recommended) to Oil Mixture (using Motorex Cross Power 2T at a 40:1 - 60:1 depends on oil quality) and when KTM says to Change the transmission oil the amount called for is 0.7 liters engine oil using Mo…torex Top Speed 4T 15W50. \n \n. \nThese Quanities are from an 04 250SX could not find a 2000. So consult with your local KTM Dealer's Service Department and pickup a Owners Manual at the same time it would be in your best interest. \n \n \n Liter breakdown \n \n0.7 liters = 0.739681 quart (US liquid) OR 0 quart (US liquid) and 1.47936 pt (US Liquid) / 0.7 liters = 1.47936 pt (US Liquid) OR 1 pt (US Liquid) and 0.958726 cups (US) (MORE)
\n. \nThe XR 250 will have more power, however, the SX80 will be quicker off of the line. It's not always just about brute horsepower, but rather useable power and how quick you can accelerate. In many circumstances the SX80 would be faster than the XR even though it doesn't have the most horsep…ower. (MORE)
\nCheck your premix ratio, carb jetting and make sure you are running the right spark plug.
Answer . If you're fouling plugs your jetting is wrong. The mixture is too rich to allow the plug to reach and sustain the minimum temperature required to allow it to be 'self cleaning'. Your suffering from reliability problems as well as a loss in performance due to incorrect jetting. Fix the c…arb.. Hope This Helps. (MORE)

\nThe KTM 360 SX is still a good bike, like all other KTM's dependable but parts are expensive when you need them. Here is a link that has pictures of the 360 SX:\n. \nhttp://www.bikepics.com/ktm/360sx/
\n. \nStart the bike up and ride it or let it idle for a few minutes to war the oil up in the engine. Then kill the engine and loosen the drain plug on the bottom of the engine. Let all of the oil drain out and replace and tighten (careful to not overtighten) the drain plug. Remove the filler plug …and add your oil. (MORE)
\nI would talk to a suspension shop about what weight oil to use for your bikes forks and your weight and riding ability. It sounds like it might be time to rebuild your forks, possibly new damper rods and springs.
They can be geared to run 100 mph but a stock 450 shoud be 90 to mid 90's.
Depends on how heavy u are. im 14, i weigh 111 lbs, mine does about 80. heavier people may only get about 60 mph.
ktm dont do 500 2ts anymore they were made in the 90s but anyway the top speed would be max 96mph but up to 70mph they are f***king animals and you would be holding on literaly with your fingernails!
Fork oil level for a 2002 KTM 65 SX is 210 cc or 7.1 OZ per leg
well many things from those engines are the same. The best thing to do is go to ktmworld.com or ktmcyclehutt.com and cross reference the parts. I only say that is because the 125sx is a 6 speed and the 200exc is a 5 speed. I do know for a fact they are the same cases so the trany will interchange bu…t do your home work . go to those sits go through the parts manuals you will like what you find ! I did! TAKE YOUR TIME !!! you don't want to take the engine apart once you put it back together its not fun ! p.s. great bikes easy to work on very forgiving but DO YOUR HOME WORK TAKE YOUR TIME!!!!!!!!

Look at the vin number on the right side of the steering head tube.\n. \n10th character identifies the year. For example: 1988(J), 1989(K), 1990(L), 1991(M), 1992(N), 1993(P), 1994(R), 1995(S), 1996(T), 1997(V), 1998(W), 1999(X), 2000(Y)------2001(1), 2002(2), 2003(3), 2004(4), 2005(5), 2006(6), 20…07(7), 2008(8) (MORE)
go to google, type in ktm 450sx quad photos and you will have lots of pictures of ktm four wheelers
\nAs of 2/09, according to Kelly Blue Book, the ratail value is $2420. \n. \nKBB Disclaimer: "The final sale price will likely be less depending on the unit's actual condition, popularity, type of warranty offered and local market conditions."

KTM recommends Motorex Top Speed 4T 15W50 - 0.7 L It is a 2 stroke motor however. So I run the 80W-85W Honda Red, or typical 2 stroke oil such as Maxima, BelRay 80W or 85W I abuse my motor at tracks and may need the extra weighted oils for extra safety
\nMost likely it is either:\n. \n1) dirt or grit inside the cable housing\n. \n2) the cable itself is frayed or bent inside the housing.\n. \nIf it is grit you can take the cable off and use a cable luber to clean it out, if it is kinked, toss it and get a new one.
\nThis would depend on what type of oil you will be using for your premix. The oil base stock is either petroleum, semi-synthetic or synthetic oil and is mixed with gas at a ratio ranging from 16:1 (petroleum) to as high as 100:1 (synthetic).\n. \nMy 2 stroke I have is a 2001 Kawasaki KDX200 that I… run Yamalube 2R at 36:1 with no problems.\n. \nAlthough synthetics say you can mix them at 100:1 I would not, that seems way too lean to me.

\nYou left the question rather vague so I will list some things that could cause this. Upon reading these you may quickly discount some, I am just throwing several causes out here.\n. \nIf it has been a while since the bike has been rode, could be old fuel accumulated in the float bowl chamber.\n.… \nGas line clogged or kinked.\n. \nEngine flooded.\n. \nDirty or wet plug.\n. \nGap too large on spark plug.\n. \nBad spark plug cap or plug itself.\n. \nWater in carb or jets blocked.\n. \nPlug connection of the CDI has oxydized.

It would most likely be a SX or MXC. It could however be a EXC that someone has pulled the headlight and tailight off of.
\nI would go with a 125 if he can handle it if he's new to riding i would start with an 80
it may look high but the shocks will go down when you sit on it
Start the bike up and let the oil warm up (side of the cylinder should be pretty warm to touch) before killing engine. Remove drain plug (on bottom of engine) and let all oil run out. Replace drain plug and remove filler plug on side of cases and add oil.
The 450 SX is a single cylinder 4 stroke, so no you do not mix gas.
Just about everything, following is some differences between the 450 SX and 450 EXC. The EXC is a 6 speed with a dry weight of 252 lbs, compression of 11.9:1, electric start and is street legal. The SX is a 4 speed with a dry weight of 231 lbs, compression of 12.5:1, kick start (09 450 is e-start… I believe) and is not street legal. (MORE)
WTF!!!! LOL! hey brother the drain plug is either on the bottom or it is on the side at the bottom of motor, It is not like a drain plug on other bikes (yam,kaw,suz,hon) it used an Allan key to open up and then it pours out the bottom on the side on the left side of motor.
Highly unlikely, I would suggest finding someone who has an 07 and checking the fit before I buy one.
br9es, br9eg, br9egv, br9ev, rn2c, if it fould all the time something else is wrong
You didn't specify what size but most dirt bikes will run a gap of 0.5-0.6 mm.
I think both bikes are same in power and specs. no i ment size not speed
Some of them are two strokes an some are 4 strokes Most of them are 2
For off road go with the XC-W. It has a 6 speed wide ratio gearbox versus a 5 speed for the SX. Bottom line, the XC-W is a great off road race bike.
You need to learn how to read plugs properly.ride bike wide open down your street and hit kill button while bike is wide open,coast to side of road and remove plug while hot. This will give you an accurate reading of what color the plugs is while the bike is running withnload on it. There are plenty… of pics onlineto show you rich or lean conditions on plugs.ideal is light brown.white ashy is too lean and black,wet plug is too much oil or a rich condition. (MORE)
new about 5,000. but is you want a good used one it would cost about 2,000
That is the basic information, anything else will depend on the brand of parts you use and what gearing etc.. you run. However another useful piece of information to have is the VIN or Frame Number, this is unique to each bike and can be found on the steering column behind the forks
Run engine to warm up the oil undo sump plug drain old oil. Replace with the correct oil and amount.
The SX is supercross and the XC is a cross country bike. The XC has softer suspension and a 6 speed wide ratio dear box.
Take the VIN off of the head tube and enter it at the link below. The tenth digit in your VIN is the year.
No they wont, the axle diameter may be the same, however the spacing for the sprockets and disc rotas will be out. It probably could be possible but you'd be using an awful lot of washers. They do fit onto the Suzuki Rm 85 However.
That is not a complete VIN number, the vin is a 17 characters (numbers and letters) that is stamped on the head tube between the handlebars and the front fender.
The ktm 150sx is a brilliant bike but also can be dangerous if you treat it dangerously (Heavy Throttle Hand). but it all depends on what you weigh and height and of course riding history. so im going to have to say it is a good strarting bike. but its a monster when you first start lol!
It does not. My 09, as well as all other year KTM atvs, have a carb. Same goes for the 500's. .
The KTM sx is fast but the yfz is the best for what I do, what kind of riding do you do?
The popular KTM 450 motorcycle comes in primarily the color orange. It isn't rare to find them as different colors however due to the easy process of repainting them.
The KTM 450 EXC is a motorcycle vehicle that is often classified as a dirt bike. The vehicle is highly recommended on the market and typically comes in the color orange.
