another overheating issue

Postby ghostdawg1520 » Sun Jun 26, 2016 5:38 pm



I have a 99 aspencade which had a coolant leak which has been fixed and i pressure tested the system to see if there were anymore leaks so far none i filled the system whick 50/50 mix anti-freeze i used the leak free funnel system to burp the radiator,soo for the past 3 days the bike had been heating to the half way mark and just a hair over that and recovering great on the hiway and in local traffic,now for some reason on day 4 when im in local traffic the bike heats up to the blackline on the right of the gauge and is not recovering any where near as fast as it was the first 3 days,so far no leaks the reservoir is filled to the correct amount,does anyone have any idea what else i can check ? btw the outside temp has been in the mid to upper eightys all 4 days i went riding

Faulty waterpump, blocked(partially) waterlines , thermostat not working properly. All likely causes for overheating problems.
I hope it's not your termostat by the way, if you have to replace that, you are in for a treat.....................

Just for giggles, I would take off the rad cap and check on your coolant level,
If it's right up, then you have 'burped' the coolant correctly. If not, top up with coolant

Your thermostat is likely stuck open if the coolant level is right. If the cooling system is working properly these bikes will never overheat. I ride mine to and from work every day on the freeway and in city traffic, the temperatures out here have been extreme, 112 degrees this afternoon riding home and my bike sits at half on the gauge in traffic, a little more than a quarter on the gauge on the freeway. Last Monday hit 118 degrees and still the same on the gauges, asphalt temp was over 160 degrees. The thermostat isn't terribly hard to change but certainly a must. Go with oem only, don't trust aftermarket.

Glad it seems to have worked! "Burping" can be a time-consuming, annoying task, and just when you think you've got it all, more air pockets will appear. Sometimes, an air pocket will form around the impeller in the coolant pump, and no circulation happens after that. It can lead to rapid temp spikes, and long cooling down periods. Some people go through the burp process, then run it up again for a few minutes, then let it sit overnight & do it again, giving coolant the opportunity to slowly seep into the air pockets & eliminate them.

It seems like every different engine design has its favorite hiding spots for air. The trick is to know where to look, and to find a method that actually gets the air out. I've been stumped a few times (okay, several times!), and the leave-it-overnight-and-try-again method works most often for me.

That's not a bad idea mabe I'll burp it some more when I get home after work and see if I get any more air out the system

Never had a problem burping mine. The important thing to do is make sure it's up to full operating temp so the thermostat is wide open. I run mine until the fans come on which is usually hot enough to get the coolant and air moving through the system. I also rev the engine a bit, to help move things around the passageways.
