wont be a start in gear.. more than likely a ducar.. but nothing concrete... try putting it in gear, pulling the clutch in and kicking it over.. if its a start in gear, it will have compression, if its not.. the kick start will just be slacky...
ask big red for some more specific details expaiin what you want to do.. IRK etc. this is where the feedback will come in handy, as if he has looked after it, he will be proud to tell you what its got, if he has trashed it, he will avoid the questions...
keep an open mind, you should have probably researched a little into things before getting a loan off ya pop, and make sure you pay him back + some intrest(bottle of port maybe) before you start to tinker with the donk
Oh and if you can get more pics, close ups of motor, forks, rear swinger, etc, it will help other ID the parts bike for you
Hope its helped!
