crazybond700 Posted August 3, 2015 Report Share Posted August 3, 2015 Premix between 1:80 and 1:100 depending on what kind of riding you are doing, your country, etc. Gear oil for old type recommended is 5w30 engine oil. (for wet clutch motorcycles). I think around 650 (for the heavier engines). I think it is somewhere on the case. Quote Link to comment Share on other sites More sharing options...
peterb Posted August 3, 2015 Report Share Posted August 3, 2015 I've used a pre-mix of 50:1 for 20 years on GG. Use an ATF rated to Dexron III for the gearbox, 600 ml is fine. Bye, Peter. Quote Link to comment Share on other sites More sharing options...
glynno Posted August 5, 2015 Author Report Share Posted August 5, 2015 Thanks for replies , so many different opinions on here The gasgas 125 and a Beta 250 techno I've just bought will only be used for bimbling around in the woods No competition use .. I was trying to get away with running the pair of them on same premix and engine oil , just to make life easier Quote Link to comment Share on other sites More sharing options...
steve_earle Posted August 10, 2015 Report Share Posted August 10, 2015 Make sure you have permission to ride in the woods. Illegal off road riding is killing our sport and land at the moment. Quote Link to comment Share on other sites More sharing options...
