20 Most Recent 2004 KTM SX 200 Questions & Answers

Hi, sorry you might need to post this again with a model before someone can help

try changing the HT leed the spark plug cap screws into this leed if its past its sell by date the plug cap dont make good contact with the carbon fibers inside the HT leed so just change it,,,

A service manual is a valuable tool with an aging bike. I suggest the dealer/mfr. or Clymer books. In the meantime, go to the library reference section.

weaken the fuel mixture - is it air cooled? sounds like over heating

125ml to 5 litres of fuel

Yep normal. All my KTM's do that. I don't even hear it anymore because it's mentally filtered out. ;),

depends on what material is stained.. Aluminium stains can be very tricky to get clean if not impossible...some cleaners will also cause a orange/reddish stain wich will not come out unless you use some harsh chemicals to get them out. problem is it's hard to get to those chemicals. IF you happen to have a truck wash nearby where they wash the big trucks (18 wheelers)take your parts there and tell them to use some brightener on it it's a chemical that really cleans aluminium.it may cost you a little bit of money but that stuff really works and i haven't been able to find that stuff for private sale anywhere. the number 2 reasons for stains on the bike are : 1) waiting to long to wash the bike some types of sand/mud especially the red dirt we have down south here will stain a bike if you leave it on the bike not only that it dries as hard as concrete and is very difficult to remove , so was your bike ASAP. 2) washing chemicals. Some chemicals / soaps when they are left too long on aluminium will leave stains as it reacts with the aluminium , these stains are almost impossible to get out. ,,,

have found the info i need in thetechnical how too's but was told it is shims and done differently?Yeah it's shims. Point the marks on the cams at each other on compression stroke (i.e. after inlet valves have closed) then check the clearances. No need to lock the crank. If they are out of spec then you need to lock the crank at TDC remove the camchain tensioner and remove the cams to get to the shims. Be careful cos the shims can stick to the followers and drop off into the motor. Measure the thickness of the shims with a micrometer then calculate how thick the replacements need to be. See the thread the other day about putting cams back in. It's all pretty easy and the good news is they hardly ever need adjustment,,,

which one would be the best?First of all there is no sxc it's sx exc mxc. The difference in the sx and exc is the sx is strickly a mottocross bike. It is not geared or setup suspension wise to ride in the woods. It is much more radical than an exc which is designed specifically for woods riding.,,,

Did you get water down the exhaust pipe???
Take the spark plug out,clean it and put it back in.The oil coming out the pipe may be soot and water mixed together.Try this and see how you go

you will need to check the wheel bearings, and the internal spacer between them, the speedo drive can also cause this if the tabs are not lined up with the wheel

That would be like riding a fixed wheel bike.Think about how you will stop and start. Only hydraulic fluid will leak. Bad idea!

Question edited for clarity. That sounds like it is just a bad connection somewhere or possibly a bad switch. Remove the battery leads and clean the lead contacts and battery posts with a wire brush. Smear with Vaseline and reconnect. Remove the starter leads and do the same. Then it could be the Starter Relay https://www.google.com/search?q=ktm+450+sx-f+starter+relay+location Or Starter Button https://www.google.com/search?q=ktm+450+sx-f+starter+button+replacement ..

personnaly I would replace cylinder with new OEM

All dirt bikes have a VIN. It is on the steering neck. https://www.google.com/search?q=vin+on+my+ktm+300 ..

Have you checked battery connections. Run switch in the correct position? Checked spark plug for debris? Just thinking out loud..

Drain oil. Use degreaser to clean area. Use JB Weld & allow to set up properly before adding oil.

Hi, most likely your cdi unit or ignition coil needs replacing.
