Apologies for resurrecting an old post but I thought it better to keep relevant information in the same place. It is common knowledge the FZS1000 charging is only just adequate, I've always found it lacking myself. In the last few months 3 mates had RR failures on their bikes, 2 VFRs and a BMW. Following their investigations I decided to upgrade the Fazer with a MOSFET regulator.


I took a slightly different but not as efficient route as Robbo. I sourced a used Shindengen FH012AA regulator from a 2008 R1. The going price for these is about £50. There are plenty of brand new chinese copies/replacement units available cheaper than this but if you do a bit of homework it becomes apparent they are generally pretty poor. (One of my mates had one fail after 2 weeks).


I didn't upgrade the wiring or run it directly back to the battery. The white connector under the tank was in very good condition so I left this in place. I could have made up a new loom from here to the reg. Instead, to save a few quid I cut the cable off the original regulator and fitted the new connectors required.


The hard bit was deciding how to physically mount the new reg. After a bit of head scratching I decided the best position was exactly where Robbo had put his. Thanks to the excellant photographs I made a bracket that looks just like his. I might have been able to move it 20mm further towards the front of the bike but it's fine where it is.


I bought the new connectors from eBay. There were cheaper ones but I went for some at £13 thinking they might have been better quality. I wouldn't recommend them, they didn't seem as good quality as OEM equipment. I suggest you buy these from a reputable wiring accessory supplier if you try this yourself.


I haven't done many miles yet but checks with the multimeter show better charging performance. Other posts on the forum suggest the alternator isn't man enough to power everyting at tickover, that seems to be a fair assessment to me. Hopefully putting more power back in the battery as the revs rise a bit will ensure there's enough charge left in the battery after every ride.


Thanks again Robbo!
