Hello,
ive got a BP5ES plug in and the mixture is 70ml of Castrol super TT per 5 litres of super unleaded. Ive had the bike 4 years now and serviced it regularly but never needed to alter the plug for summer or winter, its always been spot on.
The fan did seem to be on all the time at the trial this weekend, and ive noticed that when ive topped the water up there is a slight amount of oil on the cap when i take it out, and it does seem to dribble out a little when its warming up if ive topped it right up. Other than that it doesnt seem to use any water, it doesnt go below a certain level and theres no water in the oil.
i was wondering if the bikes had a thermostat like on a car?? that may not be letting water through to cool the engine?
As for a kill switch, the bikes never had one.
cheers..
