Question about 2000 KTM 640 LC4
We have a dirt bike, we go to the beach and dunes a lot. Every time we go thu water we take the starter off, disassemble it and wash the armature with carb cleaner or gasoline, if we don't do that, dirt and rust build up will make the starter slow and heavy. While is off, it turns just fine, but when installed, it can not turn the motor fast nor long enough to start it up.
So my recommendation is to disassembly the whole starter, not just cleaning the brushes contact points. Starters are not complicated at all. If nothing is broken, the solenoid is good, the brushes and contact surface is good, the only other thing is dirty armature, as simple as that.

I am no bike expert but this sounds like a simple mechanical issue. Either the starter is not properly aligned or needs repair/replacement. If you can't kick start the bike because it is or feels like it is locking then there is something not aligned correctly. A weak starter or a starter with an internal problem will give you this symptom. In fact, you could narrow the problem down a bit by removing the electric start totally and see if that clears up the manual start problem. If it does then you know the major problem is the electric starter.

Hi! Looks like that the starter is faulty. The solenoid is surely worn causing it not to kick the engine with force. If you have an extra one try replacing it. This will surely work. Please be sure that you got fuel and a good set of spark plugs and plug wires. Hope this helps and have a good one!
