Good to know – thank you for reporting back. $150 is actually not unreasonable, if it does what it says. I just ordered a BP, based on your findings (which makes you responsible for life ) I assume the richer fuel mix may negatively affect carbon emissions, but luckily, even here in California's regulatory madness, there is no smog check for motorcycles (yet).
I will confirm (or deny) the Boosterplug's claims after installing and using it for a bit.
