so i picked up my 1st bike yesterday, after wanting one for a few years, i found it on ebay gpr50 and paid £150 (i know why it was so cheap now).... Theres oil over everything, the fairings are knackered, the wiring looks like it was nibbled at by a hamster and is full of spade connectors, there are no keys, (well half a key in the ignition switched on), the chain is about 4 links too big, there was no battery (it starts with a bump though) rant over heres the main reason for the post.... I put a new battery in today, and tried the electric start, it made the right noises but didnt really sound like it was turning the engine. I took the starter motor out and the spring that pushes the solenoid back was in bits. Can I get a new spring or do I need a whole new starter motor? I've only seen genuine parts so far and they were charging £179. If the spings arent availible could i pick up a cheap motor from fleebay get the spring from that and fit it? or... Is this acctually the problem or could it be something else. Its the first time ive worked on a bike but I've been messing with cars for a few years now.
