    Help with bent alternator locking thread

    I have a crank wheel that the threaded end where the alternator lock nut sits is bent. The easy fix would be to get another wheel, but this is a 533 crank which are pretty scarce here in NZ and the crank has been rebuilt, welded and runs very true. It does not need to be 100% as it will be...

    Re-winding of XT250 stator from 6V to 12 V. Doable?

    One of my sons have a 1982 XT250, sort of a monoshocked baby brother of the XT500. This is actually a nice and lightweight little offroader. I believe its main drawback is the poor 6V headlight. The alternator and ignition on this bike is PMA type and CDI. I assume any 6V alternator can be...

    Alternator/Left Crankcase Cover Bolts

    Hi all, I purchased my XS650 without any bolts for the Alternator/Left Crankcase Cover and haven't been able to find them on the threads. Does anybody know the size/dimensions of the 6 bolts or if there is a kit online where I could buy them? Thanks! Matthew

    Alternator specs

    Hello, I took some measurements on the alternator I have and I need to know if they are good readings. It will eventually get replaced with a PMA kit from Hugh's but those are expensive, I am broke, and they are out of stock at the moment anyway. So for now, I am hoping to be able to use this...

    DIY Reg/Rec. 5twins and Jim

    This section deals with the '80 and newer A type regulator system. For '79 and earlier bikes, see comment #2. Comment #3 discusses using modern rectifiers. So, I've been getting quiet a few PM's lately about how I wired my reg/rec on the 80SG resto. I know there's a lot of info on this site...

    Bike will not stay started - Alternator?

    This morning bike started normal with choke depressed as I waited for it to warm up. But when I opened the choke up and went to leave my garage as soon as I started to accelerate I lost power and it cut out. I went to start again and it seemed like it didn't want to, but I figured it wasn't warm...

    PO ruined my lower case.

    So I have the bike torn down and rewired and all but ready to ride and I go to find that one of the mounting points for the stator to be bolted down has been destroyed. Looks to me that the PO broke a bolt off. Then broke an easy out. Then decided to drill it. The hole is mangled. No chance...

    I Somehow Fried My New Stator

    Hi guys, I've been reading this forum for a while as I've been working on my '78 Special, but this is my first post. This spring I did the PMA swap using Hugh's kit. The swap seemed to work great and for a few months the bike was riding great. After a few months, however, the battery...
