'85 Interstate Steam from both exhaust pipes

Ok, I have another question. When my 85 interstate sits overnight, and it's been a cold night, steam comes from exhaust on both sides when started. The bike does not miss and runs well. The steam stops after several minutes and does not appear again until after sitting overnight, or for several hours. I cannot detect any "sweet" smell in the steam, and the coolant level does not appear to be going down. I am concerned because there is SO much steam. Am I worrying for no reason, or should I look into this further? Would a compression check reveal anything?

 

Thanks in advance.

Is it just steam... which dissipates, or is it smoke?

It's most likely condensation in your pipes. I don't know where you are but with the cold nights and warm days your pipes are going to "sweat". You probably see it on the outside of the pipes as well. I would bet it is just burning the condensation out of the system. Nothing to worry about especially if you don't smell antifreeze and the level is consistent.

it's steam, as it does dissipate.

 

thanks

you will get that a lot if you just run the bike for 5 min intervals to keep the battery charged, don't panic as it is native to most bikes with a restrictive exhaust system :yes:
