What you’ll need:

When you’re done…

Check to confirm that all fittings and connections are tight, and then you’re ready to start your motor and enjoy!


**After enjoying your first ride with your newly installed BOV, be sure to check all fittings one more time, as things tend to loosen when they get hot.

    I have a GP1800 and I bought the blow off valve kit from Riva Racing but they tell me I can’t connect the plastic tee to the map sensor. If I connect to the map sensor cause something wrong failure to the Ecu?
