Hi, Cg_brewer for the day no for an extended period of time yes for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary, transport your bike to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your problem.

The cheapest route is to overhaul the and clean the carb. The only pproblem is that you can have both of them be the problem. On mine I had to replace the jets and overhaul the carb to get it running right. It ran better when I just did the carb but not how I wanted it to.

SOURCE: I have a carbureted ZX-11. I am going from 4500

you have to adjust the carb for sure on your way up and down.... the reasoning behind it is the air change... the higher you go the less air there is, lower you go the more air there is... you'll feel your bike struggle, bogg and spurt and thats when you know to pull over and adjust it while its running....

SOURCE: all stock , very bad

The motorcycle was most likely set up at sea level or 400 feet. You have near perfect temperature and not to bad for humidity but the air is thin or thinner then what the motorcycle needs. I did a Google search but was unable to come up with an exploded view of the KTM carburetor. If the bog is that sever off idle you might want to drop a couple of high speed jet sizes. Buy a few sizes run the engine for a little bit and then pull the plug it should be running a light tan to coffee color if it's white then it's way lean and if it's black it's to rich. Right now I'd bet it'll look wet

I just moved from Charleston, SC to Colorado and went from sea level to 6,200 Ft above sea level...do I need to make any adjustments for the higher altitude?


it its fuel injected it will have an atmospheric pressure sensor that compensates for altitude. if its carbs you may have to alter the height of the needle and slightly smaller main jets

Typically, When you go over 3000 ft above sea level you should adjust the calibration or jetting in the carbs. If the bike is very sluggish at 6200 ft you may have to lean the carb out by installing smaller jets and lowering the needles. the carbs are very intricate and should only be serviced by a qualified technician.
Thanks and I hope that this helps.

What should the stock carb jets be for a 94 yz250 with the stock pipe and aftermarket silencer


Stock Jetting for a 1994YZ250 is:

350 main
45 pilot
J8-6EJ33-61 needle

Adjust your jetting down one size for each 1000' of elevation above sea level. Needle clip position on the needle fine tunes the pilot circuit.

My yamaha yz 125 is dumping to much fuel and fouling out the plugs but i need to knoew how to adjust my carb its a 1997


There are only two adjustments to make on your carburetor; the idle speed, and the idle mixture adjustment. If the spark plug fouls frequently, first make sure you are using the correct spark plug. Your 1997 YZ125 uses an NGKB9EGV. Then be sure you are using the recommended two stroke oil, mixed to the proper ratio, in the fuel. Also make sure the air filter is not excessively soiled.
With all of the above confirmed and corrected, start the bike and run until the engine is up to normal temperature. Adjust the idle mixture screw to attain the fastest idle and best throttle response. Then adjust the idle speed.
If you are still fouling the spark plug, verify that the carburetor has the correct size jets by consulting your owner's manual. Keep in mind that if you are operating your bike at an altitude higher than about 6,000 feet above sea level, the stock jetting may be too rich. Down-size the main jet in small increments until satisfactory operation and the correct spark plug color is obtained.

Jetting


WHAT MEAN JET? : Carb jetting can be easily understood if we understand the basic principles of carb and engine operation. A carb mixes fuel with air before it goes into the engine. When the mixture is correct the engine runs well. The bottom line is a carb must be adjusted to deliver fuel and air to the engine at a precise ratio. This precise ratio can be affected by a number of outside and inside influences. If you are aware of these influences you can re-jet your carb to compensate for the changes. I'm going to show you some examples of how you can change your jetting for better performance and in some cases increased engine life. As with any engine work be sure you have good tools the correct parts and a good manual before you get your hands dirty! ALTITUDE COMPENSATION: For our first example let's say we find a new riding area WAAY up in the mountains. Our jetting is dialled in for our usual riding area which ranges from sea level to 1500 feet. Our NEW riding area starts at 4000 feet and goes up from there. Going to a higher elevation will require will require a jetting change but which way? Like our fuel density air density can also change. Higher elevations have less air density then lower ones. At high elevations our engines are getting less air so they need less fuel to maintain the proper air/fuel ratio. Generally you would go down 1 main jet size for every 1750 to 2000 feet of elevation you go up (info for Mikuni carbs). If you normally run a 260 main jet at sea level you would drop down to a 240 at 4000 feet. Something else goes down as you go up in elevation is horsepower. You can figure on losing about 3% or your power for every 1000 feet you go up. At 4000 feet your power will be down about 12%-even though you rejetted! For our second example let's say we are still at our new 4000-feet elevation riding area and a storm comes in. We head back to camp and ride it out overnight. The next day there's a foot of snow on the ground the skies are clear and it's COLD!. Aside from getting the campfire going and making some coffee you should be thinking about jetting again! Cold air is dense air and dense air requires bigger jets. If the 240 jet ran good the day before you will need a bigger jet to run properly today. If the temperature is 50 degrees colder,,
