Morning, Looking for some thoughts/advice on the above issue. Anyone had similar? Was out for a ride and the bike started to overheat. Pulled in immediately and stopped, noticed coolant on the floor while waiting for recovery. Got the bike home and stripped it down and ran it for a while, noticed leak from lower intake on the engine, coolant being forced out of the rubber hose where it seats over the metal intake seal. Tightened it up, topped up coolant, took it for a spin and after a few miles, temp started to head up to max. Stopped, recovered home, again noticed the leak from lower intake. Pulled the thermostat and stuck on boiling water, opens well and no issue. The coolant doesn’t appear to bubble in the expansion tank. Just forced out through lower intake. Im thinking this is a water pump issue. Anyone had this type of experience? How do I check the pump? Any other items I should rule out first? thanks
I'd personally take this as a chance to swap all the hoses to silicone. AS3 performance do some good ones without the extra cost of going with samco. Then maybe switch to waterless coolant after flushing the system. I noticed when I switched mine that the rubber around the clips was splitting due to age which is never good. No real issues since.
+1 above on silicone hoses with the Evans coolant..... can’t rate it enough. Expensive one off cost but lasts the lifetime of the bike so really a good deal.
Mine did this on my 2006 track bike. Pressure test the system and watch for little piss puddles and can easily find where it’s from. Mine was the OEM oil cooler finally gave out with 30,000 miles and 3 years hard track riding.
Silicone Hoses are they way to go. Mine now sits 1 "bar' less on the dash on the temp gauge. Also set the fan to come on earlier with Tune ECU. Factory is 102 but 96ish should be alot better.
