New Moto Guzzi Door Mats Available Now
pull the plugs, and would be best to also remove the header on that side. Then spin the starter. If you get lucky it will pop out one of the 2 open holes. It might pop out the exhaust port easier because of the pressure release when the exhaust valve opens, so I would probably leave the plug in on that side. No plug lead attached of course.
Don't feel bad. Have done it on the T-3. Did pull the head but that is quite quick and simple on a T-3.GliderJohn
I would have been most concerned that a piece would have lodged on the valve seat and put a bending force on the stem as it was closing.Anyway, if it’s run as long as it now has post disaster, the bit/s must have shredded, melted or otherwise disintegrated.Since you have compression on both sides, nothing can be awry…
No need to ground the plug. Turned over fine. No sign of the broken piece. I’m guessing it passed through the exhaust already. Seems to turn over fine. Gina complete the valve check and go from there. I held the pen in my hand to prevent this but it did. I tried doing this gingerly but here I am. I’m glad it’s a small plastic piece but wish it hadn’t occurred. There’s no way it’s still in there now.
I turn the motor till the exhaust valve is open and adjust the intake valve, then open the intake and adjust the exhaust. First time I tried the tdc method the screwdriver stuck on me, probable same way it broke the pen. Decided I'd do it the other way.
That’s going to be ok if you have concentric base circles on your cams, if not, you will meet trouble using that method.What is so damn hard about just getting the damn thing to TDC on the compression stroke ?
