its a blue box jay760....

What is the best coil to run with a boyer ignition set up... I am building a bike and the coil is bad... want to replace the coil with something that will work and not have to buy a whole new system. ? I saw mikesXS has some coils that could work... any info. THANKS!

does anybody have a flywheel puller - 24x1.0mm female rh thread puller I can use today/ this week???? thanks!

Ok, so wiring up my first Boyer ignition.. Pretty basic 5 wires: Black/ white and black/ yellow go to the plate the reads off the cam. White is Ground. Red is Positive and that is connected to the kill switch wire. Black is to Ign. Coil.... ? The coil has 2 terminals - positive is...

Just rebuilt the top end, new valve guide seals, brand new carbs from 650 central... I'm thinking it is coil/ spark plug related because it did the same thing with my old single carb and intake. Not sure why gas would come out unless the plug isn't igniting it.. But it will run, so I'm...

1977 xs650 I have been having a few problems with my bike and am trying to figure it out. Last time I rode the bike it was really down on power and when I parked it, I noticed fuel was coming out of the right side exhaust. I then pulled out the plugs and found that the right plug was...

and modified the clutch springs

the motor was a little rough when I got it, so it was completely rebuilt I sent the crank and cam to Hugh and I got started first painted the whole engine black

thanks to David Roy @ Voodoo Vintage for the sweet frame

working on resizing some photos... I want to post the process from engine to built bike

finished her up and got some pics in Transworld Motocross Mag - April 2013 started with just a motor and took about a year to fully finish the bike

New issue that has just come up with my xs650. It has a rephrased crank and cam from Hugh - did about 8 months ago. I went to ride today and noticed it was really down on power, then parked it and noticed the right side exhaust was wet with fuel. Possibly stuck open float needle? Or...

Ya I'm thinking its the reg/rec since the battery has been tested and came back good and I just put on the brand new stator.. Any idea what the output on the stator should be? (Off the 3 yellow wires) I'll probably need to order and new reg/ rec unit from Hugh or find one for a PMA system...

I'm getting a reading of just over 3 AC volts while the bike is idling... Is that right? Or should it be more with the PMA?

Trying to figure out what's going on with my bike... I already checked for continuity between the 3 yellow wires - 0.6 ohms on all Want to check the stator output but not sure where it should be at?? While the bike is running (idle) what should the 3 yellow wires be reading??

So here's where I'm at... Had the battery load tested - it's good Hugh sent me a new stator - plugged everything in Same reg/rec Started the bike up and road it around the neighborhood, when I came back to the garage the voltage dropped to 11.7 With the bike idling its at 11.7, rev it...

Ok, so I was having trouble with my charging system... Found out the 3 yellow wires got cut by the rotor sometime during the past couple weeks. Could this have done damage to my reg/ rect? I connected the wires and taped them up but still no charge.

Thanks for the insight... I'll check out some of the pma threads.. In the meantime I pulled off the rotor and checked the stator, found a bid problem - the 3 yellow wires that run from the stator to the voltage reg/ reg had loosened up and the rotor sliced thru them, 2 of them. So I cut...

Looking for a rotor puller in OC area.. Having some electrical issues and trying to diagnose the problem. Thanks!

I'm having the same problems as you guys experienced with the bike not able to run and voltage drops.... What ended up happening/ fixes??? I'm a motocross mechanic, but not too familiar with the xs... This being my first build
