Was curious what vacuum line I should use for the oiler. I hava California Versys and the direction say use the vacuum hose on the charcoal evap canister with the supplied T valve. Or is there a an unused vacuum port I can use:feedback:

There are 2 plugged up ports at each throttle body that you can tap into.
If you havent done the IAP mod, that is.

I question the value of connecting the throttle bodies with a vacuum hose like this (IAP mod). 1) The manufacturer would have done this if it offered any significant value 2) No motorcycle manufacturer has joined throttle bodies or carbs this way 3) The vacuum in the throttle body goes up and down as the cyl sucks air. When one cyl is drawing air the other is not so a linking vacuum line should reduce the vacuum which will upset the fuel air mixture making it leaner.

Reports of better rideability on slow speed came with the IAP mod. Perhaps the MAP sensor which monitors the Left TB has now also been able to monitor the Right TB with the IAP mod, making it more accurate in reading the vacuum conditions of both TB.

I tried the connect the throttle bodies. It didn't work for me. Bike did not run as well and mileage went down. I un did the mod and was glad to have my bike back. I had already done the TpS adjust by volt meter. That made a huge difference, mine was under spec.

Maybe if you hook your oiler to the right side only it will have zero effect on the EFI.

I do not have the IAP mod the directions on the oiler say connect between the hose from throttle body to canister purge valve. It is the hose with a white line on it. Those are the directions for the CARB certified model.

Would it cause any harm to attach the Scottoiler to -
a. the balancing tube (assuming you've done the mod)?
b. at one of the spigots on the 2 throttle bodies that have bungs on them?
