Hey guys, I'm new to the forum. I bought a 98 vtr1000 recently, and I'm having overheating problems. I was riding down the road when my bike starts to sputter, I look down, and the temp gauge is near red. I had the fan going, so idk what was going on. I look to see if there's any coolant, low and behold there's no coolant at all in the resevoir. I add more coolant. Next day I did a complete coolant flush, and added 50/50 Prestone. It's running better, however, teh resevoir is depleted again. I went to the local auto parts store to see what's going on, and they said to check the spark plugs. Therefore, I go change my plugs, and it seemed like a milky residue is on both spark plugs. I also checked th coolant lines for leaks, and there aren't any. Could it be a blown head gasket or does anybody what could be the issue? Thank you
