Mini Bike Maintenance

Mini Bike Maintenance is crucial for alot of reasons:

1) Cleanliness
2) Durability
3) Safety
4) Efficiency

Here’s a detailed guide on the best way to keep your mini bike

The Chain

For proper mini bike maintenance, you need to learn to size your chain, however this really is not difficult. After this, you have got to keep it correctly adjusted and lubricated.

Re sizing your chain

To resize your chain the pins have to be taken out from the link out. Affordable tools are sold that do this — or drive out the pins with a punch that is somewhat smaller diameter in relation to the pin.

Make certain you do not remove too many links. Most will let you know that you can not use multiple chain clips. And it is more easy to remove links, anyhow.

The chain is reconnected after removing the correct links. The connecting links are sold with a clip snap that will keep the pins in place.

Carry several links of chain and spare clips as a piece of a little tool kit in your toolbox.

Correcting the Chain Tension

After a certain period of time, your bike chain will start to stretch and will probably fall off if you don’t do anything about it. In order to adjust the tension of your chain, firstly you need to loosen the engine mounting bolts, this will allow you to move the engine block forward and backward.The right quantity of tension is all about 1/2″ of motion in the chain when examined between the clutch and sprocket.

It is important that you allow the chain to play a little. In case you over-tighten, the horse power and chain life will degrade. And severe over tightening will cause the clutch to get engaged when you are at idle position.

When fitting a brand new chain, expect the chain to relax a bit. You might need to correct the tension several times the first couple of rides out on a brand new chain. Bike tension is one of the most crucial part of mini bike maintenance. To learn more watch this video on removal and installation of chains.

Lubricating the Chain

Mini bike chains is called as roller chains. How it works is that the steel pins will rub against the inside of the steel tubes. This “rubbing”will require some lubrication to make it smoother. Proper chain maintenance will require you to apply lubricant on the chain directly under the tubes and on the pins for extended lifetime of the chain.

The best method to lubricate is to remove the chain and soak it in lubricant over night. If you are unsure of which lubricant it is always helpful to visit your local dealer for their recommendation. The lubricant will need time to sufficiently penetrate the rollers — just spraying over the chain is not adequate for mini bike maintenance.

In the event you need instant lubrication, you can get by for the day with waiting a couple of minutes after a fast spray, but you will wind up with lots of chain- spray on your clothes and small of lubrication applied.

Aligning the Chain

When doing mini bike maintenance on chains, make sure the clutch and drive sprockets are in alignment. Misalignment will cause wear that is more rapid.

To check the chain alignment, rotate the drive wheel in the reverse direction and check if the chain is properly feeding straight to the back to the rear sprocket. The chain should sit right in the middle of the sprocket. If not, try to adjust the alignment by adding or removing spacers until the drive wheel and the sprocket is straight and aligned.

Worn Out Components

One important part of mini bike maintenance you should not neglect is the inspect the worn out components. Replace the chain when there’s too much slack and does not fit between the sprocket teeth correctly. Replace sprockets should they’ve “pointy” teeth from wear.

Oil Maintenance

Changing the oil is not a difficult task, it is also cheap and one of the most neglected part of mini bike maintenance. Doing it on a regular basis will increase the life span of the engine of your bike.

Oil Level

Before taking your bike on a ride, check the oil level. the level should just about to touch the end thread of the oil cap.

How to Change the Oil

There is a couple methods to get this done. The very first is the filthy and simple manner, as well as the second is the way that is harder and cleaner. Oil will flow better and will remove sludge when the engine is brought to operating temperature before changing the oil. Use caution as the oil will probably be quite hot, if done this manner.

The Simple method

A Briggs engine is going to have square-headed bolt in the very bottom of the block. This is the drain of the engine. By removing the drain plug, the oil will flow out from the bottom drain of the engine, make sure to remove any sludge that might get in the way of the sludge.

Sadly this means the oil flows out around the mounting plate — and into your oil catch pan.

The Hard but Clean method

It’s possible for you to remove the engine and dump the oil, this method will not work if you heat your engine first, the flush with this method will not be as great. Alternatively, you can remove an oil-filler plug and tip the entire bike backwards on the rear fender, dumping the oil into a a pan that is carefully placed.

Mini Bike Maintenance Schedule

how frequent you need to do your mini bike maintenance and change the oil depends on the specifications of the engine. Briggs advocates changing the oil after once per season or 25 hours of usage. Considering that bikes get more activity than lawn mowers, make an effort to stick to the hours use.

End of Season

You will have to do some simple things to put away your bike when the season finishes.


Drain the fuel from the tank by letting the engine run until empty. If a crab is installed with the bowl, inspect the bottom of the drain plug at its foundation. Remove the rest of the gasoline from the tank via evaporation in an open, ventilated place away from any sparks or fire, or by using rags. Use care.

Some products like “Stabil” are made to keep gasoline, but the best bet would be to remove it.

Before using in the spring, remove the spark plug and add a bit of oil to the cylinder. Replace the spark plug before reattaching the spark plug cable and pull the starter.


Know about your brake and accelerator cables when keeping. Lubricate the ends with alternative lubricant or WD 40 so that they do not get stuck.


Keep the machine from the rain. You will be saved rust problems by an affordable tarp!

When Springtime Arrives

Perform regular care when you are prepared to ride again.

  • Oil all components
  • Check tires for dry rot
  • Use fresh gas
  • Check air filter
  • Change the oil
  • Oil the engine
  • Adjust the chains
