SOURCE: My KTM Duke 690 spun out on me while going no more

Hi Kathy,
Sorry to hear you have had a drama. It is often travelling at low speeds where you may experience problems like this, and come off the bike.
Things to look out for here are loose gravel or sand on the roadway where the problem occurred. This will make the tyres slid out from under you.
If the bike is brand new, another thing to look out for is products like tyre shine that may have been applied to the tyres whilst the bike may have been in the show room. Also new tyres have a wax coating that reduce levels of traction when brand new. you may have dipped a peg on the ground that could have levered the bike over on you also.
Hope this has helped you understand a little what has happened, perhaps get a biker mate, or bikeshop to check it out for you before you go riding again to be sure that there are no contaminants on the rubber surfaces of the tyres.
Happy to answer any questions you may have.
regards robotek

SOURCE: wiring diagran for ktm 690

My best suggestion is go to your local library and they will have your diagram. Our local library has wiring diagrams online. This way it is free. You can order a manual from the bike shop but it is going to cost money that way. I have looked all over for wiring diagrams on the internet and have had no luck finding any of them. I have even paid for them and they always seem to be wrong. Or no help.

How to tighten a bycyle chain

Generally bicycle (and motorcycle) chain tension is adjusted by the position of the rear axle. On bicycles you would move the axle farther back to tighten (forward to 'loosen'). Motorcycles are a little different as there is actually (usually) a specific adjuster for the axle position (same as bicycle though - rearward to tighten/forward to loosen). Hope this helps

My ktm duke had a low battery i fitted a new one and the ignition worked fine but now it dose nothing but bike kick starts

Check your stator and voltage regulator for proper output. Sounds like the battery isn't receiving a charge through the system. You can charge the battery with a trickle charger to verify the battery will take a charge outside the bikes charging system.

Problems with 640 duke starting,not a battery fault any ideas?

remove the sparkplugs and ground them to the engine try to start check for spark at plug if sparking check for compression put your finger over plug hole try to start if it pops off check carb for gas (didnt say if it was running and then sat for a while) with spark and compression and good gas it should run if your finger dosent pop off then the problem is no valve movement to create compression(broken cam chain) that would allow the engine to roll over quickly or whirr as you said check these things and let us know

i know you have to change the oil and oil filter but how often and is that the only thing different from maintance on a 2-stroke?. Im getting an 04 kx 250f any help would be great!The two most important aspects of four-stroke maintenance are frequent oil/filter changes and regular valve clearance checks/adjustments. And some four-strokes (RMZ450 for example) have a manual timing chain tensioner that must be regularly checked/adjusted. Everything else is exactly like a two-stroke.,,,

Put it up on your stand lossen the axel and remove the bolt on the bottom of the shock. Then tighten your chain and lift your swingarm up until its horizontal with the ground, then the chain should have almost no play. Not completely tight, but almost no play. Tighten the axel, and the bolt on the shock, and your set,,,
