    Engine failure question

    Thanks again for your help and confirmation. Should be running tonight-ish

    This is something. I indexed all the rings as the service manual instructed. When I pulled the piston out, this is how they were. How common is it for all the rings to turn and line up the gaps?

    Here is the newer piston that I just put in. It has always used a little oil. I think the exhaust guides are worn. It started doing that after I did the cams and springs. I'll check the seals too. Probably needs a head job.

    The skirts are worn but no heat signs. I'm sure it still got very hot when I lost the coolant. im going through wheelie withdrawals... I think I'm just going to tear it down and install the new cylinder and piston kit and see what I find in tear down.

    Performed the leak down test after getting it running. There was only a 10% loss and it sounded like it was coming from the crankcase. It also sprays oil out of both the valve cover breather and the cylinder vent (next to cam chain). More than I think is normal old piston looked fine.

    I can post that picture no problem. in response to your post, let's say the piston, rings, and cylinder is fine. Brings me back to my original question: What else could it be?

    Leakage, I can accept. Blowing all the oil out of the motor into the airbox, that has to be something else?

    I will do it today and let you know what I find. However remember, this is a new piston and rings with less that a couple hours. So we are assuming that if there is a leakage into the crankcase, then its probably the cylinder or another possibility?

    Overheated

    If the piston goes down, isn't a valve opening? Do you hold the motor at TDC on the crank bolt? My leakdown kit also has dual gauges.

    To perform a leakdown, don't you have to have the engine warm? It's in a non running condition. Also, is it ok to run the cylinder pressure on a leakdown test over 90psi?

    I was assuming piston and rings. I think a blockage would cause a lack of oil type failure. No signs of that.

    Engine failure question

    Hello everyone! I have a KLX400 that has been in supermoto trim for as long as I can remember. I have a big bore MT kit, hot cams, ignition, and other engine work. Recently I crashed and popped a radiator. Was able to limp it home, but I fear it overheated. After replacing the radiator, went for a ride and it blew all the oil out of the crankcase, and into the air box. I noticed the plume of smoke and towed it home. Tore down the motor, replaced the piston and rings, mic'd the bore and it seamed fine. (I am concerned of the accuracy of my bore gauge however) After the ring replacement, about a month later, same engine failure. Oil in air box and enough smoke to fill an entire neighborhood. I have just purchased a new cylinder kit and am in the process of rebuilding now. My question finally, is there something else I should be looking at that I may be missing? Thanks in advance for any thoughts. kevin
  15. Know of any? We are trying to find more things to do when out riding so we are looking for fellow TT'rs experience here. Basicly asking if there are any cool games that guys do on the bikes when out on trails to increase the ride fun. One game we came up with is H.I.L.L.. Basicly like HORSE in basketball, but played on differant hill climbs. Any other known games out there? Please share.
