Matt Gunter My Ride Posted January 13, 2016 Hey guys I've had this 2004 Rmz for a while I recently rebuilt bottom, top, and valves everything is brand new bike starts and runs perfectly. I'm having trouble with it blowing oil out of the bent tube on a straightaway on my local track, also when the bike is started and then shut off after a few oil slowly leaks out after it is shut off, I always drain all the oil out and put the specified amount in just curious if anyone knows a fix, my rear brake pad budget needs to be cut. Thanks. Share this post Link to post Share on other sites

speedtoad Posted January 13, 2016 Have you done a leak down test on the rebuilt motor? Sounds like excessive crankcase pressure. Share this post Link to post Share on other sites
Matt Gunter My Ride Posted January 13, 2016 Haven't done a leak down test I will do that right away but what's a good fix for too much case pressure? Share this post Link to post Share on other sites
speedtoad Posted January 14, 2016 but what's a good fix for too much case pressure? Bad piston rings or cylinder are a cause. Share this post Link to post Share on other sites
Matt Gunter My Ride Posted January 14, 2016 Did the leak down everything checked out okay I had the vent routed the wrong way it was kinked by the carb, runs great no problems had it out in the snow yesterday 1 Share this post Link to post Share on other sites
