I've been having a lot of trouble with my little YZF-R15 recently (not starting and stopping at weird times). I took it to the mechanic and they found the problem...it's the fuel pump. An OEM Yamaha fuel pump costs around the $500 mark and unfortunately I do not have that amount of cash (and especially since it's only a $2000 bike). Is there any other cheaper alternatives I can turn to? I saw this an item listed on eBay titled (since I can't post the link) "New Intank Fuel Pump 2008+ Yamaha YZFR15 YZF-R15" but I'm not sure if it'll do the job. Thoughts?
