Thanks for the quick reply. No, i didn't not adjust timing. Can you guide me in the right direction on how to adjust the timing? I can't seem to find it in the "How to" section... Vince

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've been having on and off carb issues. I have pod filters and non-baffled straight pipe exhaust. Recently installed Hugh's hand build PMA. I have Bs38s and on my 1978. Main jet = 145. Pilot = 35, I changed both. Mixture screw is at 2.25 turns. At first, my bike would not idol correctly, it...

Cleaned up the carbs. Main jet 145, pilot at 35. B38 carbs. 2.25 turns on the mixture screws. I know one of my coils is a little shotty. Bike starts and runs good, but when I get on the gas it hesitates. At full throttle it gets up and goes but then bogs and the power is shorted... Any suggestions?

What about the diaphragm?

No, everything is fine.

I understand it could be the butterfly seals, but I cannot find a good picture of them or how to replace. Also, where is there a tutorial on how to do the dead cylinder test!

Pilot is 35**

Not sure?

I have a 1977 xs650. Bike starts up fine, but when I ride, I'm getting a shortage of power. I've battled wiring/electrical problems ever since I bought the bike. I redid all the wiring, because fuses kept blowing. But now the bike just isn't riding right. I tested the stock regulator and...

I have had serious problems with my 1979 XS650 and am new to building these motorcycles. My bike currently will not start due to a fuse that blows every time I start it. I am planning on re-doing the whole wiring. Any opinions on what sites I can buy all the wiring from? I have an aftermarket...

Thanks gentlemen, ill dig into it and keep ya posted!

No turn signals. 1978 xs650, does have 4 separate fuses. Probably due to the aftermarket headlight, speedo, and tail light. Whats the easiest way to pin point a bad wire? Continuity test?

Thanks again LEO, the two wires coming into the fuse that keeps blowing are 1. a red wire with a white stripe coming from the ignition coil (near the front of the bike under the gas tank) and 2. a black wire feeding into the wiring harness for the regulator rectifier. Something is causing the...

I purchased this bike used from a friend. The bike seemed to have some electrical issues because every time I would ride, one out of the 3 fuses would blow, losing power to the tail light and headlight. The main fuse never blew. Just one of the 3 others. I though it was caused by the rinky dink...

Leo check you PM

I just replaced my stock tail light with a new LED tail from Lowbro Customs. Every single time i start the bike the 10amp fuse blows! I checked all of the connection and everything seems fine. Any suggestions?
