Hi guys i have a 04 yz450f with a big bore in it. here's my problem i switched over to engine ice this past weekend and my weep hole started to leak again not as bad as the first time but just one or two drops while i sat there idling. after about 2 hours of riding my radiators took a little more than 3/4 a quart to fill them back up. I have read on alot of other forums that if you see bubbles in your antifreeze your head gasket is leaking when i open the cap i can see fluid being pumped right across the top of the radiator can someone explain a little more to me about what everyone means by bubbles,should i not be able to see the antifreeze moving at all when the engine is running or do i check for bubbles right after i shut it off??? also i saw about 250* degrees in some real tight trials this weekend is that too hot it ran about 200 to 210 on the rest of the trails but they weren't as slow going.I also filled my radiators up when i got to the truck and then i filled up my turkey baster and my turkey baster was empty about 10 mins up the trail.I am going to replace the water pump seals again and put on a boyesen super cooler and give it a try and see if im still losing fluid. i just dont understand the bubbles in the radiators i guess. also i heard of a better coolant than engine ice what do you recommend?
