xs650 birdbox challenge. help me.
Guys, please help me. I’m completely at a loss and don’t know what’s going on. After I static timed my motor it started right up and ran strong. I took it around town a couple of times in a couple of days as a testers (mainly cause I was waiting to time it dynamically to ensure I’m running within spec)
Ok let’s start the brain scratching.
1978 XS650 special
Today I got it up to temp (ripped around the side blocks for 15 mins) and planned on setting the dwell on the points and dialing the ignition dynamically.
My dwell was pretty close from the start, I got both points to 22.5 with no problems.
I used my timing gun on the flywheel and it was showing that I was sparking in the middle of the full advance mark and the Fire mark.. it was running real nice where it was at but I dont really have anything to compare it to.
I went to adjust my timing plate but the plate was maxed in the direction I needed to go. The backing plate (right cylinder) was maxed in the counter clock direction. When I tried moving it the other way it ran like crap and actually stalled.
I didn’t know what to do, I checked the cam chain tensioner and it was good (center pin was flush)
I started to static time it again to see if I can fix or find something.
Pulled the exhaust valve covers off to make sure I was working on the compression stroke.
I set up my test light and everything to static time and I can’t get it to light anywhere near the fire mark... I get a light when I’m between the fire and full advance mark..
WTF!
There’s nowhere to move the plate, I really don’t know what I’m missing, I dont think that this plate should ever have to be maxed in one direction.
PLEASE hit me with everything you got, I’m a novice at timing it might be simple and obvious to you (I hope) but please just point me in a direction, thanks guys!
It was running fine at this setting (plate maxed counter clock)
And this is the plate maxed clockwise
