i have a gas gas 250 2005 and i was going to clean the carb but i noticed that on my mates gas gas 125 there is a pipe coming the carb going to a different place (see pic) can someone tell me witch setup is right or if both is right? One is a clear hose and one is a black hose also his 125 dosnt have a fuel filter will this matter?

when i was out on my 2005 gas gas the weekend i had been on it for about an hour had a break and then fired it up after checking it was out off gear i kicked it off and it was as if i had started it in gear the bike started doing a donut with me holding on to the handle bars, after i manage to hit the kill switch i tried again and the same thing happened can anybody explain this...

i recently got a gas gas 125cc 2005 and have not been out on it yet but started it up and left if running for about 20 mins today and the fan never cut in at all is something wrong with the bike, i have toped the coolant up what do you think....

I have just brought a 2005 gas gas 250cc so my knowledge of engine's is rubish the problem i have is doing a oil change i know where you drain the old oil and i know where you top the oil up i just dont know how much oil to put in or where the dipstick is???
