I've got a 2005 Brute Force 750 that just had the main timing chain replaced (It broke) along with a couple valves (Bent). The engine work was done by my Mechanic but I removed & reinstalled the motor.
Put it all back together and it fired up nicely. I let it idle for a bit and pulled the dipstick to make sure I hade enough oil in it. Major pressure coming out of the crankcase, it was as if I had my hand in front of the exhaust! Tons of coolant in there as well!
The guy who rebuilt it is very good and I know I put it all back together correctly. He obviously missed something, anyone have any thoughts?
