Learning how to change oil on a 2 stroke dirt bike is very easy, it’s also one of the first and most important maintenance procedures you should regularly undertake. It only takes a few minutes out of your day but it needs to be done properly.
Here is a step by step guide on how to change oil on a two stroke dirt bike..
- Firstly,always work with a clean bike. It’s best to warm your bike up beforehand as the oil drains better when hot. Take it for a spin then turn it off.
- With the bike upright unscrew the oil cap on the side of the engine casing. Be sure not to drop any dirt into the transmission.
- Placea drain pan or bucket underneath the bike and unscrew the drain plug to allow the oil to come out. Tilt the bike from side to side to get as much out as possible.
- Once it’s all out screw the drain plug back in making sure not to cross-thread or over tighten it. If it’s damaged replace it with a new one.
- Pour in therequired amount of transmission oil through the top filler hole. Check your manual for the correct amount although it should be printed on the side of the engine near the filler hole. My YZ 250 takes 750ml of SAE 10W – 30.Note: Some bikes have a ‘check bolt’ on the side that you can unscrew to check the oil level. If oil comes out it’s good. If no oil comes out you need to fill it up. Other bikes have a see through glass window so you can see the actual oil level.
- Wipe away any dirt from the oil cap and check that the washer is in good condition to ensure a tight seal. Screw it back in finger tight.
Questions & Answers
How often should I change the oil on my two stroke dirt bike?
About every 5 hours riding time. If you ride pretty hard then every 3 hours. Of course you can get away with longer periods between oil changes but it will cause more wear on the transmission.
What oil should I use for my 2 stroke dirt bike?
Vegetable oil – Ah just kidding! Use only high performance two stroke engine oil. Make sure you use a quality brand like Castrol, Motul, Yamalube, Belray, Putoline, Silkolene etc.. They aint cheap but they will prolong the life of your engine significantly over other inferior oils.
Tip: For a few bucks you can buy an after-market magnetic tipped drain plug that attracts the metal shavings floating around inside the gear box.
And that’s it! Make this a regular part of your maintenance routine and your beloved Two Banger will repay you with years of riding time.
