This requires a 10 key and a candle key. The key to the 10 is to remove the cover from the top 3 bolts. Then it is necessary to looser the bolt cutter, looser the handle, looser the tube.
Now we need to roll four bolts, one at each of the ignition, and remove them with the coil to access the candles.
Now we need to do it with an effort, but without the swimsuit, it's gonna turn out the candles. The new need to be curled carefully so that they do not recling or damage to the engine thread. Damage to threads can lead to costly and complex repairs.
