Right cyl. still not smoking

[pearljam724]

Yeah, Coyote. Suction !

Well, i had my lines off, i cleaned them (not with compressed air) i took the oil pump apart, cleaned it (i was able to save the gasket) and i hooked the lines up to the pump and i turned it with a drill, I watched the pump , pump the oil through all the lines , i checked this over and over and everything worked great. I know the pump and lines are good, so either my right cylinder is lean or the left and center are burning tranny oil, not sure which yet , but im more afraid of my right cylinder burning a hole in the piston than I am burning oil., thanks for all the info guys!

Eddie,
That tells us that the pump is OK and that none of the lines is blocked. It doesn't tell us if a check valve or two is leaking and doesn't confirm whether or not an oil nozzle is blocked.

- Did you remove the SRIS valves and drain those two crankcases? If so how much oil came out?

- Did you do a "drain down" test on the lines to see if a valve is allowing oil to drain past the check valve?

Those two combined give a pretty good indication of which lines/valves are leaking.

If you did the two color test described above, you would know if oil is being pumped to all 6 lines.

Eddie - just to add a bit to TZ's input - a very east test is to remove the right cover and mark what the level of the injector oil is in the tank. Let the bike stand for 48 hours and then check to see if the level has dropped at all. It doesn't take a lot of injector leakage to generate an impressive amount of smoke. And +1 to pulling the SRIS valves and checking them - they can plug up (as can the SRIS hoses) as well as stick open.

When i had the octopus off I filled the lines with oil and hung them upside down for about 2 or 3 days, and there was very little oil that had drained out of one of the lines, very small amount, probly not enough to do any harm.I then flushed the lines clean with carb cleaner and wd-40, then hooked up the pump and made sure it pumped oil to all lines,(i actually cleaned them 1st then oil, then cleaned again). I took the sris valves off at the bottom of the motor, I have done this several times now, and the last time I did it, i got a decent amount out of the left and center cylinders which are the ones that smoke, it was not alot but more than the right cylinder, im not sure how much but around 5 mills i think. I did not take the lines off from the upper part of the jugs, just the bottom,( i dont even know if you can take them off from the top?) anyway the sris valves are not clogged at the bottom , i was able to squirt carb cleaner through them, my middle sris valve still had the screen on it, and the others did not. I was worried about a crank seal creating a lean mixture on the right cyl, but even if it was lean it would still smoke right? if it was getting oil? the plug looks tan , i will take a picture and post it as soon as i get back, I have to recertify my license once a year, and it takes 5 days!!! of testing so iv been studying , i finish friday and will be able to take pics and video probly sat, or sunday if i dont forget by then!

That all sounds OK. Sounds like you did the right things there. The extra oil in the smokey cylinders does suggest that perhaps the check valves were weeping before they were cleaned and the surplus oil is now in the pipes.

When you run the bike try opening up the oil pump lever to full at a fast idle and if the right cylinder now starts to smoke, I'd declare it OK and just run it hard enough and long enough to burn off the oil in the left and center pipes.

Or, and I hate to suggest this, you could pop the pipes off and see if left and right are really oily. I pulled a set of pipes off recently and they dripped black oil for a day leaving a trail across the shop floor.

Eddie could you take a measurement of the temperature of the header pipes?

[Coyote]

You know what I meant. But, you had to bust my balls. Ah ha!

I wasn't trying to do that. I respect those things. Of course at my age, they are merely decoration.
