if its anything like my 2000 savage, you need to remove the tank to get at the bolts that hold the chrome cover in place. Once you remove the chrome head cover, you should have pretty easy access to the spark plug.
Quality depending.
a good branded quart of oil is priced around 15-20$. One thing you CANNOT cheap out on is oil.
I have to assume you're talking about Standard Byke's 125R vs. Standard Byke's 250 Series frames, correct?
First off, the intended purpose of these two bike frames are completely different. A 125R is a racing frame (thus the "R" in "125R") while the 250 Series are Freestyle frames.
As far as "size" goes, the 125R and 250 come in five different sizes: 20", 20.5", 20.75", 21", 21.25" (250 Series only) and 21.5" (125R Series only) top tube lengths. So to answer your question: A 125R and 250 are the same size if you compare the same two sizes, but the 125R comes 1/4" longer than the longest 250.
usually u mix it 40-1 for 4 gallons u use 12 oz of oil not shur about 5 but not that much more
first drain your old oil with the drain plug on the left hand side of the bike, replace oil drain plug. then remove the oil fill level plug on right hand side of the bike on engine casing. add oil(15w50 is spec i think, but dextron atf works), until it begins to run out of the hole when the bike is level. replace plug, replace oil fill cap. have fun
The front number plate and fender will fit. The side number plates, rear fender and airboxes will not. The 2005 KTM bikes have the side number plates attached to the rear fender (all as one piece) the 2003 models have number plates that attach indiviually (not as one piece)
the engine power and the seat height
250 SX manual calls for Motorex Top Speed 4T 15W50 ( .7 L)
KTM the famous motorcycle manufacturer do. They are an Austrian company that have been making very high quality motorcycles for years, they also make excellent bicycles using high spec components. Unfortunately they are not officially for sale in the UK yet but hopefully will be soon.
For 2008, KTM won the 85cc shootout, however there are more things to consider than someones opinion on what bike is best. Pick a bike that suits your riding style and size. Also, it doesn't matter how good a bike is, if you don't have a shop to help you with getting parts and technical knowledge, your bike is just another bike.
Your top gear or last gear you shift to. Depending on what make and model of your bike, either 4th or 5th on motocross bikes and for woods bikes it would be 5th or 6th.
Take a small cup and pour just a bit into the cup. If the gas has been premixed with oil it will be a color depending on what type of oil you use. On my 2 stroke gas can, I always dump the oil in the can first, then take a piece of duct tape and write how many gallons of gas is needed for the amount of oil I have in the can and buy my gas on the way to go ride. If I change my mind on riding that weekend, I don't have premix gas going bad in the garage and I have a reminder of how much gas to add at a later time.
Does it have a safety "kick stand" switch?
It a wire grounding when you sit on it?
Loose coil wire?
Does it cut out no matter what position the throttle is in? In other words, will it stay alive if you pull in the clutch, keep the revs of the bike up, then click it into gear?
If so, this might be a clutch issue, such as a grooved clutch basket not allowing the plates to separate enough. An easy fix, if you know your way around an engine. If not, I suggest taking it to the dealer. Otherwise, try the easy fixes first, play around with the barrel adjusters on your clutch lever and see if it goes away. If it's cold outside when this happens, try running a slightly thinner transmission oil to keep the clutch pack from sticking together.
I don't know, it was in the lineup from KTM for 08 and is in the 09 lineup also.
