Cranking problems, battery?
First post here but I've been creeping on these forums for a while now. amazing info here.
I've been having a problem with my 03' 750 where its not wanting to crank easily. sometimes it works, sometimes I have to do a push start and dump the clutch it get it fired up. I've replaced the spark plugs with Iridium ones I found the info for on here, I replaced the starter today. still not 100% on the cranking. the bike is making a whining sound, kinda like a whirring coming from around the starter area. after its been cranked up for a little while it tends to crank right back up after I cut it off. so I'm thinking its the factory battery not putting out enough juice and maybe when it runs for a bit it charges back up to full capacity allowing for easier cranks. I'm planning on getting one of the MF gel batterys you folks talk about so much but I want to make sure the symptoms match the correct problem. sound like the factory battery to you guys?
p.s. I was also having overheating problems when in traffic or parked. found what I guess is the radiator temp sensor for the fan on the bottom left while sitting on the bike. the plug was loose and a little corroded. cleaned it up, crimped it a little and plugged it back in. fan kicks on while its running now. so thats 1 problem down.
