You might have to drill out the lock By drilling a hole down each side of the key slot and put steel pins in the holes and twist the key way if possible to unlock the cap

check battery

if you turn a motorbike tank into reserve..
the patrol wont go to a little filter.. soo.. thats the splutter and so..

Try ebay.
Hope that helps

You can get new wheels on ebay, or at your local motorcycle dealer, and it does not have to be the exact same tyre, but it does have to be the same hight, i would reccomend bridgestone tyres as they last a hell of a lot longer than the stock, well worth your money

The problem is that one of the bulbs has blown or you have a bad earth connection on one of the black wires coming from one of the indicators,clean connections with wet and dry sand paper. Finally check the wattage of the bulbs is correct something like 3-5 watts ,

Not sure how much this will help...but....if you can't get a hold of a Derbi dealership (I'm pretty sure that Derbi is owned by Piagio now,) You might be able to go to a piagio or vespa dealership...once again if no luck, usually a good cable will run you about $30.00. Any bike shop that does moto cross stuff should be able to custom make one...(they use special solder for the ends) and usually not for a lot of money either....30.00-50.00.

When you have it on main there is a little pipe that sticks higher up into the gas tank and once the gas get down below the top of the pipe it will start to make the engine sputter and you have to flip the lever over to reserve so the rest of the gas can be used. But once you have used up all the gas in the tank you will be empty. So when ever you flip it to reserve you will only have about a 1/2 gallon of gas left to get you to a gas station to get it filled back up. No there is not a separate tank in side the main tank.

check fuel tank vent,fuel filter,float bowl vent

looks like you have a nut at the rear of thr swing arm, one on each side, these are the rear wheel/chain adjusters. slacken the wheel nut and then adjust the nuts, there should be some kind of markings on the swingarm so you can get both sides the same. when done tighten the wheel nut and you are done

There are several schools of thought on this. Some say you should change your oil every 3000 miles; others say every 6000 miles is fine. In any case you should change it every 3 months.,

Hi mate if the cable had not been seated into the speedo drive correctely it will give you intermittent spinning.
Take the cable off at the speedo drive at the wheel and repeat the lifting spinning of the wheel and watch the "actua"l speedo drive spin.
If that intermittent pull the wheel off and inpsect the speedo drive itself.
Its a basic unit so should be an easy fix.
Other wise replace it if you dont think you can fix it.
Hope this helps

You need a test light or multimeter and test for power from the bulb connector back. It could also still be the bulb as the broken filament could still be making contact occasionally. Remove the bulb and flick it with a finger while watching the filament. You are looking to see if the filament is vibrating. If the bulb is good wipe it with a clean rag before replacing. Check the high low switch contacts are clean and all wiring connectors.

I assume that is a 100cc, 2 stroke ATV? If the starter motor is spinning, and you just don't have any spark. First, replace the spark plug. If that doesn't fix it, then you may have one of the following problems: Bad CDI, Kill Switch or Rip Cord Shut off switch, Frayed wire shorting out, cracked/damaged spark plug cap, bad coil or coil wire, bad stator. My bet is on the kill switch and/or Lanyard/Rip Cord shut off switch or the CDI. You can bypass your shutoff switches to see if they are the problem by either disconnecting the wires or connecting them together(depending on the type of system you have). CDI's routinely fail on small engines and generally cost about $20-$70, depending on the style. www.solanocycle.com

ill tell you right now whats wrong, your using the completely wrong oil

I know you said you cleaned the carb, but maybe something got in the carb when trying to start the bike. Because it sure sounds like you have a clogged pilot jet.

Fixya is unable to source parts.

One of these. You buy by make and model, not by size. https://www.google.com/search?q=2008+derbi+terra+flywheel+extractor.

What state is the battery in? Fully charged? Did it work before the overhaul? Check your wires again from top to bottom

Use a airlift or comparable coolant system air removal/refill system.You attach the unit to the coolant system filler and it vacuums all air from the system,then you use the supplied hose to return the coolant into the vacuumed system.This fills the system with just coolant and no air.
