Posted July 25, 201014 yr I have just bought yamaha yb100, its spuing oil from exhaust and loads of white smoke, it also wont run over 40. can anyone tell me what mix oil and fuel it should have?
July 25, 201014 yr If if is standard you shouldn't have to mix fuel and oil in the petrol tank. Look under the RH or LH side cover below the seat and you should see a seperate oil tank that must be checked regularly and kept topped up with two stroke oil.You should also have a red oil warning light that comes on when the bike is in neutral as a bulb check but if it comes on when you are in gear you are getting low on two stroke oil. Usually it is best to check the level in the tank at least once a week depending what miles you are doing and top up as neccesary. Tony.
July 25, 201014 yr Moderator If you have just bought it take it back. Otherwise check the gearbox oil on a daily basis and even money says it will be dropping. Crank seals, bit much on a new bike.
