battery

Hey all. I need to order a battery for this project ‘73 xs650 I inherited. Is this the stock battery box? And if so, can someone confirm the battery size I need? I mistakenly ordered a Yuasa YB12A-A and that was too big for this compartment.

Hi! did anyone use one of those new noco lithium battery. or does anyone know which one is compatible that could replace a 8cell antigravity battery. thanks

I just picked up a 78 650 Special. It has been sitting for 30 years. I hope to rebuild it with my son (for as long as his patience lasts anyway). In any event, I am a total noob here. New to bikes, relatively new to vehicles (I putter on some cars and "figure stuff out"). As such, if you...

It’s that time of the year again! Yep - my dumb ass needs a new battery. Does anyone know the model number for a 1980 XS650 Special battery? Preferably just like a standard Yuasa? Thanks!

Hey guys, I’m in the middle of a Cafe build on my 77 xs650. I’d like to keep all my stock options (headlight, taillights, turns, push button start, speedo, etc.) I was looking into upgrading my charging system to the PMA style from TCBros (link below). Could I then run an 8 cell antigravity...

I have a Ballistic evo2 8-cell battery that won't keep charge anymore and I need to replace, but they don't seem to make these anymore. Does anyone know where I might be able to pick one of these up, or know what happened to the company? They don't seem to exist anymore... I'm also looking into...

Hello all, I've sketched up a wiring diagram for my 1975 XS650B, which is a hardtail chopper project. it has the stock alternator, as well as: a TCBro's reg/reg: http://www.tcbroschoppers.com/regulator-rectifier-yamaha-xs650-points-ignition-models.html. a TCBro's headlight...

I have Pamco ignition system with the EAdvance installed on my '81 heritage special with the stock solid state regulator/rectifier and im having a bit of trouble with my charging system. I followed Curly's charging system troubleshooting guide that is reposted all over the place and got to...

Hi everyone, Ive recently bought my first 1980 XS650. I bought it not running.. This is my first kickstart bike and I was wondering if its possible to kickover the motor without a battery? Just trying to do troubleshooting and want to see if having a battery or not is going to matter in terms...

So I'm having an odd problem with my 1980 XS650 that has seemed to develop within the past couple of weeks. Whenever I go to start the thing with the electric starter, it will crank over perfectly fine but won't fire up until I let off the starter button (when the engine is attempting to slow...

Hey folks, Long time (four years?) lurker, first-time poster here. I'm having some really sluggish turn over with my starter and I'm not entirely sure what the issue is. I'll try to be as detailed as possible, here's what I'm running: 1981 Special, running a new HHB CDI charging system (with...

Hey Guys, I switched over from my capacitor over to an Antigravity battery. The bike starts/runs a lot stronger but now it blows fuses as RPMs rise to mid-range. This bike never blew a few before, all I did was change the battery. Voltage regulator is new last season. I redid my wiring last...

chasing problems with bike running I believe may be battery. Runs for a few moments cold then dies, won't restart till sitting. Took me a bit to realize the battery was weak (kick only) Kick only '74, pamco ignition, updated coils from mikes (the dual output black one). Original charging...

I'm new to the forum but have been reading threads for the last couple years. Finally got the chance to do an xs build myself after a friend with a garage sold me an '81 Special motor with an accompanying hard tail frame. I was stoked. I dug right in but due to work, rookie mistakes, and other...

I finally had a chance to test start my bike, but once I put the battery on the tailight and gauge lights came on and stayed on (pushing the pedal didn't make it change brightness). The horn didn't work and the high beams dont work but the headlight on/off switch worked. I also cant turn the...

Hello everyone, I had previously posted about getting a new charging system. Well, I fixed here up! My 1973 TX650 now has a functioning stock charging system with a solid state reg/rec unit. I had her fired up and charging! It was worth it. However, I am a bit confused. Maybe the community could...

Hi all, I have been having issue with my bike and am relatively a newbie working on motorcycles. My issues are: Battery loses charge sitting overnight. I have but a tender on the battery got it back to 100%, it starts with a little throttle but cannot stay running. Pulled choke which keeps it...

Hey all, I have a 72 xs650 that has a PMA I pieced together years ago. No kits were available. I have a 5 wire reg rec combo feom Hugh if I remember correctly. Also running a pamco unit and small headlight taillight. Etc. I've tried the small cig box size batteries and killed cels in both. Now...
