I have a 1998 ktm 65 sx I just bought it when we test rode it it ran good but we only took it to 3 rd gear then when rode it after getting it home the first time it went into 5th gear it got stuck there...

Thank you for contacting FixYa with your inquiry.
The first thing we need to do is eliminate the possibility that the shift lever is not interfering with anything limiting it's travel into the top three gear positions. It's possible that the lever is bent or has been incorrectly re-installed on the wrong spline position.
That being said, we more than likely have a problem with a bent shifting fork, a pall, or a shift rail, maybe even a broken gear.. There is also a good possibility the engine has been previously disassembled and not had parts replaced and the engine did not get re-assembled correctly. You will have to remove the engine and split the case to inspect the shafts, shifting forks, spacers, and shifting drum to correct the problem. This link will take you to the complete shop repair manual for this bike. Check the section 4 beginning on page 36-37.
You may have to make some holding parts and/or rent some pullers but it's not to bad of a project. A good KTM Shop can always fix the problem but it's expensive. This is a great little bike. I'm sorry it's having problems.
Thanks again for contacting FixYa.

A week ago i took my bike to get fixed at a shop it had been sitting for about 2 years the guy said it was a dirty carb and a dirty gas tank he cleaned both and the bike ran fine i rode it for 2 min. or so...

Try replacing spark plug,and check for spark if you do good,check to see if you have fuel to carb,at bottom of carb there is a float bowl screw loosen the screw and let fuel drain,tighten screw,choke and try again,sometimes when bike sits that long it may need one or two cleans,the bad gas that was in it still has varnash build up and can still clog up the jets.hope this helps.

Ktm 450 sx wont start when hot.

Had this very same problem with a KX 85 last week! Turned out funnily enough to be the spark plug. So try this first mate. If that dosn't fix it then you have the age old mechanics question "did I do somthing wrong or is it just a coincidence". Start back at your beginning next & re-check your valves.Most of these late model bikes(12000-16000rpm screamers) have titanium COATED valves. Once the coating wears off they close up valves REALLY QUICKLY!!!!! If the clearances are ok your work was good & at least it will rule out insuficient valve clearance as the cause to your problem.If it still plays up - well then I would use the process of elimination to solve the problem i.e is it electrical,fuel, or mechanical. With valves checked already a compression or leakage test would pritty well rule out the mechanical system.To test electrics on motorcycles without test equiptment & a lotof know how can be difficult & EXTREMELY DANGEROUS( shock hazard 40,000 v+). So I'll try keep it simple. On the web you can purchase ignition spark testers that will connect to any plug lead & cause the ignition system to jump a gap of 6 to 8mm.These are cheap & will test the system as a whole for its performance. Great for a quick check of any ignition system. If the spark seems fine then your left with the fuel system. check for blocked fuel tap,water in tank or carby bowl,blocked fuel filler cap vent,blocked carby vent hoses,accellerator pump function.
I hope this has been somewhat helpfull.
I am happy to help with further questions

Fuel becomes like a gel substance if the bike was not used for some time. There may be some gel blocking the main jet of your carburetor. If the gel formed in the tank, it may take a while to reach the carburetor. That may be why it operated without a problem for a while.

Well, depending on what your mechanical skills are, it may be tough to troubleshoot and fix your problem. I have the same exact bike, and it along with all other sport bikes are tough to work on because everything is very confined. You first have to start with the basics, Fuel, Spark, and Compression. Your going to have to get the fairings off and remove the gas tank before you test any of that. Once the tank is off, you can get access to the spark plugs and wires to do a spark test. Also while you are there, check to make sure the carb is getting sufficient fuel, or even possibly too much fuel. Leaky needle and seats in the carb bowls can cause lots of problems for starting and idling. And please don't blow yourself up! Exposed gas and spark test can equate to big flame balls if your not careful. If you need more help, I'd be willing to do what I can for you so shoot me an email at

Did you do a compression check just for the sake of saying the motor did not seize? Have you checked by grounding the spark plug to make sure there is not spark? Your problem really sounds like a seizure. You may have lost the CDI box.
