I did my first autotune (basic) run with Power Vision a few days ago. Now I'm getting oil dripping from air filter. Never had this issue before.
Is the "new" tune causing the oil blow-by, or is it coincidence?

 

I'd say coincidence. The oil has probably been slowly accumulating in the air cleaner and it finally accumulated enough to start dripping.

Did you do anything else? Like change air cleaners or something.

 

I changed the stock air cleaner with the FuelMoto Stage 1 air cleaner last summer. Never noticed blow-by until I did the autotune last weekend. I'm gonna flash the ECM with the old map and I'll do a test run to see if it drips oil.

 

How many miles have you ridden the bike since changing the air cleaner?

The reason I ask is because if you don't ride that much it may take a while before the oil can accumulate enough to start dripping. If you only have 3 or 4 thousand miles since installing the air cleaner then my theory becomes even more plausible.

I'll be interested to see what you find when you go back to your previous tune, but I'd bet the farm the oil will still be dripping.

 

when was the last time you cleaned your filter? did you overoil it when you were done? how about change your engine oil? how much oil do you keep in your sump? a lot of stage 1 bikes don't like the oil level to be past the halfway mark in the hashmarked operating range. more than that, and the bike spits it out until it gets to where it likes it.....

 

I installed a new filter las summer. I've ridden about 2k-3k miles after that. I usually do the oil change myself (oil level is on the full mark). I will be doing an oil change in the next few days (and will pour less oil). However, before the oil change, I will re-map and go for a test-ride to rule out my crazy suspicion.

 

Skratch has a good reason, your oil sump cold will benefit at half dip stick. Even though a stage one provides more air and increased horse power it also seems to make more engine heat.
