"OMG no the HARD BREAK IN! You're going to blow it up." Oh yes the hard break in and that DRZ400 or I should say DRZ434 LOVED IT. So Loud and Daves DRZ400, wait you know how Loud and Dave is right? I heard some nopes. Ok LINK BELOW,br Ok so Loud and Daves bike already was quite modded out. He had the 3x3, FCR 39mm, Hot Cams, Full exhaust and a GardenSnake Sticker (best mod) but he wanted MOAR! So big bore kit it was. Slapped her in pretty fast as well as adjusted some of the tightest exhaust valves I'd ever seen. AND BOOM 1000HP!!!! Ok not really but shes got some go. Almost hangs with my WR450f which is damn impressive. Oh and the hard break in thing. Ok so I know theres a LOT of opinions on this. I'm technically a Certified Motorcycle Mechanic so... I might know what I'm doing. If you want to hear more about hard break ins check this video out where I explain in detail why you should do this.
