Lost timing help!

Samclyde · Post by **Samclyde** » Wed Apr 23, 2014 1:23 am

I recently replaced the head gaskets on my 78 gl1000. When I was putting it back together I accidentally let the cam roll once. I thought I had it back in the same spot but it won't run right. So to make matters worse I figured I would just re time the whole bike. But now it won't even sputter. I tried what the book told me to do and I think I have the cams on the wrong stroke. I can't figure out where to start a base line. Any help would be very much appreciated thanks

Seeing as how you have been rolling the engine over with possible mistimed cams any further damage is impossible.

Remove the timing plug and turn engine to the T1.2 mark and check where your cam marks are.

Ok I have been dinking with it all night.i removed the timing plug, and lined up t1 and the made the right side valves match up to that mark. (I'm going off that the right hand front cylinder is number one.) Then I spin the engine till the mar t2 comes up and make the left side valves match that and nothing happens. So I figured I was 180 out so I took the belts off and spun the engine 180 degrees and tried again with no success. So at this point I am stumped and I don't know. Which way to turn. Please help me!!!

Once cam timing mark on the crank is set, both marks on the L/h and R/H cams should line up, the wheel are stamped with the mark UP on them
you don't set one at T1, then Turn the engine over to T2 then set that up

Yep, to clarify: set both valve timing belts with crank at T-1. You are probably thinking of setting ignition, or the rotating of the engine to set belt tensioners. http://www.ngwclub.com/forum/viewtopic.php?t=3544

Still no luck everything is lined up t 1 and bkthe can gears. Alls I get is the occasional backfire.I know it runs because I drove it in the garage. So it has to be something to do with the timing being off is the ibky thing I can think.

Check your plug wires? Easy to get them reversed if they are not numbered.
