Posted August 2, 200817 yr Hi, yesterday I rode my bike in to work, no problems. When I tried to start it up the next morning, the battery was dead, did about two swings and that was it. So I tried "bump starting" it. When I drop the clutch the bike starts up for about half a second and goes dead. The dash display disappearing with it. So I picked up a battery from my local bike shop and popped the new charged battery in and started her up. I measured the Voltage over the terminals and it stayed at 12V regardless if I pick up the revs or not. So I raced back home from work with the knowledge that it's not charging the battery and about a hundred yards from my home she spluttered to a halt. Dead. Now I would like to know if you have any thoughts on this. I am going to charge up the battery again now over night and take my chances to ride to the bike shop where they can find the problem. I would just like to know if there is a chance that it might just simply be a simple problem that I might be able to correct myself or can I take is as gospel that either my rectifier or alternator has gone? What do you think? I didn't know that a bike can drain a battery so fast while running... Thanks
August 4, 200817 yr Author OK, so nobody replied. Found the problem: I now have to replace the genrator stator, cover gasket and rectifier, about £400+VAT Not a cheap problem this turned out to be...
August 15, 200817 yr Author Still having trouble... Here's a pic of my alternating stator --- I have found a link to a R1 Manual in case any of you face the same problem: R1 Manual - Page 260 Hope this helps!
August 20, 200817 yr Author OK, that was an estimate from my local bike shop... They did a great job and the bill? £430 incl VAT and labour ! I just picked it up today, so I'm a very happy boy at the moment. The reason for the long wait was no one keeps the 2003 R1 (5PW7) Washer Bolt in stock. I had to wait all this time just to get the £3.50 bolt... --------------- So if you own a 2003 R1 (5PW7) and you have to replace your stator, I would recommend that you order one of these bolts so that you have it when it comes to putting your bike back together. Apparently you need to use a new one as it is fixed very very tight... The bolt part no. is: 90105 105A6
