Hello all,

This is my first post here on the forms, so - hello.

My question pertains to my Yoshi R-77 Full exhaust system. I purchased the bike with this mod, however, so far as I know, the ECU has never been flashed and there is no PC or juice box attached. I have been reading up on the whole notion of running to lean and I decided that I wanted to get a consensus. Will the Yoshi R-77 full cause my 2013 300 to run dangerously lean? Is an ECU flash or PC absolutely necessary? I intend on getting my ECU flashed here soon, however, I didn't know if I was at risk by riding it as it now stands.

Thank you all for your help!
I'm in the exact same boat. I'm about to buy a power commander but the price is a bit too expensive for me right now.

Someone please chime in :)?
