Smoke test the twins for evap.
 

Where are tech plugging into when you smoke the twins for an evap leak? With the main evap lines tucked under the intake and the canister tucked up behind the fuel tank I cannot seem to find any good place to enter from. I also don't seem to see an evap schrader to testing the system.

Just t-off the vaccuum lines on the upper intake under the engine cover and fill the whole system with smoke?
