Looking for some help got a apex 90 thats blowing antifreeze out of overflow bottle. As long as there is antifreeze in raditor and bottle seems like its not overheating but losing antifreeze from bottle.

guy I got bike from said he added a piece of hose inside of bottle does that matter what should be inside of bottle? Hose 3 or 4 inches long or no hose?

the hose should reach down in the bottle to the fluid so when the quad needs fluid it can suck it back i think? lol but first how does it run? im wondering if the head o-ring is leaking under compression.

when I purchased mine it did the same thing I found out the hose to the pump was on backwards and was pinched,also I found out dc motorsorts is also workin to make a billet pump impeller

I had the same problem with a brand new apex 90cc, ended up being the larger o-ring, letting the hot engine gases into the water jacket and boiling it.
