Stock 07 400ex
I was riding for about 1hr or so yesterday, when the hose from the oil reservoir that goes to the top of the cylinder head pops off spewing oil out ( I think it’s a vent hose). So I reattached it and about 10 min later noticed it didn’t sound or feel right. So I checked the oil and it was boiling, let it cool down starts right up sounds feels fine.
So I figured it was overheating, any suggestions what would cause it to overheat?
The temp were like 80, and I was going slow 2nd gear mostly (with the kids) my buddy was also with us and his 400 ex ran fine so I don’t think it was the conditions that caused it.
The oil cooler gets hot when idling I, so I assume I have oil circulation/pressure.
The only thing I did do recently was an oil change, made sure filter was in correct way and took the filter out today just to make sure and put in new one in case it was defective (I could push the spring in on the rear of the filter, so I assume it was functional)
Thanks for any help
