markparrish Posted September 29, 2018 Report Share Posted September 29, 2018 assuming the coolant is not too full (in which case it will spit) and assuming your fan is running, I guess you might have a problem with the pump or some kind of blockage in the system. Maybe a good idea to take off the cover and have a look (after draining) Quote Link to comment Share on other sites More sharing options...
section swept Posted September 30, 2018 Report Share Posted September 30, 2018 That’s a good suggestion from Mark, but shouldn’t you be talking to the selling dealer about this as it may be a warrantable issue. Bear in mind every time the engine spits coolant out that depletes the anti-freeze content/strength unless you top up with coolant mix. If the water pump impeller has broken up all the pieces need locating and removing otherwise they may cause restrictions to coolant flow. Hope resolve the problem, it may just be a kinked hose causing the problem, still I’d be asking the dealer fo advice.? Quote Link to comment Share on other sites More sharing options...
klonheadd Posted September 30, 2018 Report Share Posted September 30, 2018 Sounds like the bike is overheating(if it's not overfilled). Is the fan turning on and running ok? I had such symptoms when breather from the fuel cap was blocked. This leads to fuel starvation-> lean running-> overheating-> then coolant loss. Might be a good idea to check this too.

hoodie2 Posted September 30, 2018 Report Share Posted September 30, 2018 Hope it's not but could be failed head gasket causing the cooling system to become over pressurised. This would cause engine compression to pump fluid out and would cause more than a little spitting though. Quote Link to comment Share on other sites More sharing options...
