Ok so I have the dumbest idea/question yet. 1) What are the differences between front and rear hubs when nothing is bolted on to them? 2) Can you use a rear hub, wheel, and tire on the front? 3) Do I have brain damage for asking these questions? -SLR
I recently replaced water pump and seal after I noticed that my '02 CRF450R was spilling coolant on easy trail rides. After the water pump swap (which was successful), I noticed the same problem. It's interesting - the bike only spits coolant (I mean a LOT of coolant) after passing anything above 1/2 throttle. The bike makes this weird 'gurgling' noise, like trying to suck through a straw when your glass is almost empty. This is weird because I properly bled/ burped the radiators with coolant, and filled them to normal operating levels. The coolant spills through overflow hose. anyways - I swapped the radiator because I thought maybe the bike was running hot. I purchased oversized radiators, bought a 1.6 radiator cap (with a temp gauge) and bought engine ice. The bike runs very very cool - the temp gauge allows me to see this. Still, the bike shoots coolant out of the overflow after going above half throttle, making the same weird gurgling noise when it does. Bike has all of its power, top end was replaced not too long ago. I'm lost and don't know what is wrong with the cooling system in my bike. How do I make the bike stop shooting out coolant, and stop making the weird gurgle noise??? Any advice would help me!!! Thank you!👍
