Hello, you may get more replies if you post in the 2 stroke or SM forum. Also, you should search for oil, piston, etc, because it has all been discussed before. In general, I'm not sure which motor oils are available to you in Greece, but would suggest a high quality full synthetic oil. And remember that 2 stroke bikes usually don't have much oil capacity, so it should be changed more often. Typically a 125cc runs at very high RPMs and also there's more gear shifting, so that is more stressful on the oil. There's sticky thread in this forum with a link for service manuals, maybe not for your model, but you should find something close and they have service info included.
hello guys , first of all excuse me for sharing my questions in the wrong place about the oils we dont have a problem , there is a variety of oils avaliable at many online greek motorcycle shops but there are also oils avaliable in local shops (i live in an island) so im more interested of bying oils from local shops because its easier and quicker to get them. the 2 oils i saw in a local shop are MOTUL 710 and BEL-RAY si7 are these any good? thanks
Both Motul and Belray have excellent products, I'm sure either of those oils will be fine. Many of us use a high quality auto oil like Mobile1 which can be bought in a large container and is a little cheaper than special motorcycle oils. If you change the oil often you will save some money this way. My wr300 uses only .8 liter of oil, I ride off road 3-5 times a week and change the oil every weekend, for example. If I use Belray from a local shop it costs me twice as much! And Mobile1 and similar auto oils are very high quality.
