I am working on my friends Mastiff, base gaskets, clutch work, etc... he has not ran it since last spring, i installed a new battery and turned the key on and nothing, dead. He did say he attempted to jump start it with a 200amp booster charger. Is there a way to check the computer on this bike? I see a usb jack coming off of it. Also read there are alot of issues with the electronics on these bikes. Any help will be appreciated! Jason
