timing

Hey everyone! Bike: 1979 Yamaha xs650SG bored out to 707 Ignition system: Boyer ignition I just got a new battery and it was running the other day but by the end of the day it would not turn over. The lights don't look dim but I know that its not getting enough power to get it started. I...

hey guys Hope everyone is riding while the weather is great! I have a 1978 Yamaha Xs650 bored out to the 707cc. I have currently made the bike into a chopper after the fong bros XS650 style. I am currently running stock pipes without mufflers. My electrical system is the Boyer ignition system...

I've got a 1983 with an electronic Boyer ignition, Hugh's PMA, and stock Bikuni bs34 carbs. I recently had a leakdown done and i've got 4% on the left, and 12% on the right. So, I know I won't be able to get her running perfectly, but I feel like I can still dial it in better than it is now. It...

I recently got my 73 tx650 to run after I got the timing right or so i thought i did. I rode it just locally but it usually would just die when I wouldnt ugas it no gas = dead bike (no idle bascially) it would completely turn off and it leaks a lot of gas im not quite sure where from but the...

FIRST OFF HELLO XS650 COMMUNITY! THANKS FOR THE ADD. BOUGHT MY XS650 ABOUT 6 MONTHS AGO. HAD IT RUNNING BUT IT NEEDED SOME LOVE. MY RIDE: 1977 XS650 I BOUGHT HHB COMPLETE IGNITON AND CHARGING SYSTEM, INSTALLED IT JUST AS THE DIRECTIONS DESCRIBED. MY PROBLEM NOW IS I Cant seem to get the timing...

so i bought a 1973 tx650 on ebay like a dumbass for my first motorcycle unfortunately some people suck and sell things to you by lying and saying they work when they don't. The dude said it ran and drove just fine but when it got turned on it kicked over but defiantly did not go into 1st anyway...

So I bough a beat up old XS2. I've replaced the condenser, spark plugs, point and the carbs are off getting bits done. Before the carbs went off to get cleaned up I couldn't get it started. I'm guessing it may be the timing. Anyone got any suggestions of anything else it may be and or can let me...

My set up: '80 xs650 PAMCO with E-ADVANCE PMA (not hughs,was already installed on motor, but i do have one new in a box for another motor if i need to switch for some reason) BATTERYLESS system dual output coil mikuni vm34s open 1 1/2" exhaust Just finished my bike and it was doing just fine...

A few weeks ago I removed my ignition (Boyer Bransden) on my XS650SJ ('83) because it's bleeding oil due a failing seal. I didn't know putting it back was influencing the timing (still learning). After putting it back, it bike was running fine although the RPMs went down a bit when running idle...

After buying a 78 with a PMA already installed "with no timing marks" . I rebuilt the motor and set the cam notch pointing up and pistons at true tdc; Being the pistons at the very very top. After watching a few videos on youtube now I'm hearing you install the piston stop so the pistons are a...

Hey Guys, I have read every thread on this topic. I know advance from retard. I have installed an HHB PMA, Pamco with EAdv, shaft, bushings and the replacement rotor for the right side of the cam. I believe the pin was inserted in the right place at the top of the shaft rotation. I have...

Has anyone ever seen a different mechanical timing advance I.e Harley, Honda, kawasaski used in place of the oem Yamaha piece? A Harley advance seems like the most common and easy to find, driving prices way down...just saying

My stepson had the heads rebuilt and has not been able to get the old xs to fire since seems like it should be a timing issue to me.Any ideas this is my first go on these xs's

hey just got my boyer kit setup how it tells you on the instructions, F mark on TDC and the white dot up the top, but i can't get it running fires and runs for 2 secs then stalls out if i have chokes on backfires out the carbs i have vm34's also, bike was running a few weeks ago with a morris...

I Just reassembled an XS1 engine and there seems to be a lot of slack on the back side of the timing chain. Before I installed the tensioner I was inspecting the chain and when I pushed on it, it moved until it was touching the lower/center chain guide. When I joined the cam chain both ends met...

I recently upgraded my original pamco to new plate w e-advancer. only problem i am having is, timing. I have a light and digital contact tach, i have the pamco turned as far clockwise as i can and i still seem to be quite a bit behind still. when i raise rpms to 3000, timing mark comes to...

Hi All, New to the forum. Quick question for everyone regarding my current project. I currently rebuilt (top end rebuild, new electrical etc.,) a 78 XS650. The bike fires right up and rides nice. Only problem is at times the bike dies while idling or when I pull in the clutch while...

I' keep getting a mile or two up the road and my plugs fowl out.after playing with carbs for days im starting to think it's more of a timing issue or possible vavle adjustments.any insight helps. Also might be an intermittent issue with the coil? Some info: I'm running 750 big bore/xs...

Amigos, Quick public service announcement and a request. Did the Hugh's Handbuilt PMA swap with the Pamco e-advancer. All went well. My bike is an 82 and didn't have the timing advance rod so I ordered one (part #14-0650) from MikesXS. Got about 50 miles on the bike then the rod broke...

I just installed a Pamco E advancer and having trouble with timing, when I time it using timing light the pamco sensor has to be in the full advance position to get timing marks within the fire range at 1200 rpm, everything was installed and wired correctly I have 60 degree rotor, all three...
