Hi All

At present I run my boys bike at 75ml of oil to 5 litres which works out at around 66:1. I run this the same as my txt 250.

I do get oil splats coming out the exchaust, GAS GAS Uk said that they run it 50ml of oil to 5 litres.

What oil amount does anyone else use?

Thanks

63ml / 5litres which I think is 80:1, runs well plug colour good.

With your bike if you run on a stand and rev it wide open does it bog slightly? I have cleaned the carb (its got a 70 main jet in it) cant think what else to do.....

I have played with the air/mixture screw but this does not make any difference, sometimes when holding it wide open it will also pop and backfire, riding it under load it does sound ok but I still think if my boy tries to go uphill wide open it will back fire like it was last weekend.
I have also checked all electrics and they are also dry and look in good condition, the bike is 2010 and only done 4 - 6 hours???

Any ideas or help would be greatly aprreciated!!
