Ok gents help needed. I've got an 09 rtv900 with the D902 that's blowing white smoke out of the exhaust. Starts and runs. Engine oil looks fine and no signs of coolant. No signs of exhaust gas with radiator open. When I Crack fuel line at engine on cylinder 2 it clears up some. When i crack cylinder 1 or 3 engine dies out. Ive taken all 3 injectors out, apart, and cleaned. I tried swapping injectors around and smoke still clears when cracking #2 line. Taken all fuel lines off between injection pump and engine and ensured no blockage. Pulled injection pump and nothing seems to be seized and roller springs are tight. Please help.

RTV900 white smoke

Seems that you addressed the obvious stuff.
Since the engine runs okay, with no fuel to cylinder 2, I suspect a cracked cylinder head or broken piston ring.
How many hours on the clock?
There have been reports of no radiator bubbles with a cracked head.
In my case the radiator was blocked, so no bubbles with a cracked head.

Use this adapter for the glow plug port. The Kubota pn is 07909-31301
Instructions to run the compression test can be found on page 1-S10 in the RTV900 WSM.

Based on previous posts it seems that cracked heads are more common. Either way the head has to come off to make repairs.So compression tested. Cylinders 1 & 3 are in range. Cylinder 2 is way low (100 psi). Glow plug was wet on Cylinder 2. Thinking I've got a bad ring.
