Can anyone help me figure out why I loose so much coolant every time I ride? I have a 2000 426 and I am 99.9% certain there isn't a leak in the system. I do have coolant all around the end of my overflow tube and on my right boot. I have suspected my radiator cap but I am not sure how to check if it is working properly. I noticed 1.1 stamped on the cap. I also notice if I am idling for 10 or 15 seconds coolant starts coming out of the overflow tube like it is overheating but is it just seeping out around my cap? Usually around this point the bike will shut off by itself. I am currently using a 50/50 pre-mix of a walmart brand coolant. I now see after reading a previous thread that this isn't the best idea. I am not convinced that this is the problem though. I would appreciate any feedback good or bad.
