My 1997 ktm 250sx runs smove but wen u give it a fist full there is now power band just shonds like its missing eney help just going round is sercules thanks

All being as it should it is either ignition or fuel problem. Check air filter is clean or take for run without to see difference. Do a hard cut to check spark plug reading for lean out or fouling (run engine open throttle until high revs snd cut ignition while closing throttle and pulling clutch in to stop engine. Check plug lead. Change plug. Ignition grounded. All the basics

2007 KTM 125 EXC cuts out when warm

Hi, Jayjaynoble and the usual suspects are:
1. Faulty ignition coil.
2. Faulty spark plug cables.
3. Faulty temperature sensor.
4. Faulty starter motor.
5. Valves adjusted too tight.
6. Spark plug gap too wide.
7. Fuel has vapor lock.

It wont start

well it could be because the bike sat for a while. with the 2 stroke gas being mixed with oil sometimes when it sits the oil sinks to the bottom and it will clog the valves fuel lines carb every thing. you should check.
