Supporting Your Bike While Servicing
Though covered in the service manual, many people use creative methods to support a bike while servicing it. This often results in tip-over accidents. Below we list methods that are proven to work, as well as general tips for preparing your bike for service.
Disconnecting the Battery
If there is a chance you will work on electrical components of the bike, it is a good idea to disconnect the battery. Remember that some wires are hot even when the key is in the OFF position.
To disconnect the battery:
Supporting the Rear End
Luckily, the Ninja 250 has a centerstand, so it can be used to support the rear end.
A few comments about using the centerstand:
Of course, if you are not satisfied with the centerstand, you can always buy a swingarm stand. This model from Pit Bull is known to work:
Supporting the Front End
Depending on what exactly you need to do, this can be done in a few ways:
1) If you need to work on the forks, you will have to prop the engine. Of course, you will have to remove the lower fairing for that to work. Be sure to put the bike on the centerstand to reduce the weight on the exhaust headers.
You can also prop the engine with a jackstand (which goes under the oil drain bolt). This method is less stable, but allows to raise or lower the front end smoothly and for some jacks there is no need to remove the lower fairing.
2) Of course, there is a civilized way of supporting your forks:
3) If you have access to an overhead beam, a ratcheting tie-down (with a large ratchet mechanism) can be laced between the top of the forks and the beam. If you use this method, be careful not to put pressure on any cables or wires, and ensure that the tie-down is pulling on the center of the bike. This is not the best way to do it, but can be useful when supporting under the bike isn't an option.
4) If you just need to take the front wheel off, you can:
The obvious downside is that this is not very stable. Taking off both wheels with the front end supported in such a way is not recommended. However, you don't need to take off any fairings for this method to work.
Working on the Engine
If you plan to work on the engine, you should get an engine stand.
Make sure you can stabilize the bike somehow while applying brute force. For example, you can sit backwards on the bike while tackling the rear axle nut. Another example is to start loosening the oil drain bolt on the sidestand and then switch to the centerstand.
