I've got a '90 Mach 1 that smokes like crazy. Leaves a nice puddle of oil on the floor if it idles for a few minutes. I checked the oil pump marks, and they are lined up correctly. Wondering what else might be causing this.

use zyban or nicoderm to stop smoking

1st time running??
what oil??
Is the pump marks lined up when you have cable tension at the carbs, or at slack postion (you are to set at tension)
what happens sfter you ride it for a 1/2 day, does it still do it?

Yes they are lined up when there is tension, I drained the old oil out and put Sea and Snow in it, didn't change anything. I have to gotten to ride it much since there is no snow, but the 2 trips I took around the yard on the grass it was putting on a better smoke show than most foggers!

see what it is like after you get some snow and can run it for a while, when they are sitting for a long time they can drain fuel out of the carb and into the engine, the fuel flashes off and you are left with alot of oil, start it up and there is your smoke.
Old fuel can also help with this problem also
sorry I'm thinking no oil injection, but same theroy applies, the oil system is some what pressurized and can drain alittle extra oil in the crankcase

Check your carbs look and see if the floats are level if not level them.then check too see if the choke cable is set to tight.
that will make the carbs load up fuel and oil.then fuel and oil will come out pipes. and smoke alot. my mach z had the same thing happening with it.[:)]

Well we finally got some snow today so I could get it out and ride it a little. After a couple of miles, the smoking stopped so I guess it wasn't anything major. I also remember the former owner telling me that he had added some sea foam to the gas, so that might have been causing some of it too. Thanks for all the help!
