I’m not sure what it is, but i feel like i’m overcomplicating this or just being plain stupid...perhaps both. Please help my sanity
I’m trying to locate TDC on my bike that has a banshee PMA conversion where the PO kindly didn’t leave any markings. From finding TDC I will mark the timing marks.
To try and locate TDC, i’m using a piston stop and degree wheel which i’ve read the process about on this site many times. From what i’ve seen the process is this:
1)Loosen off valves
2) Bring the piston up close to visual TDC
3) Insert piston stop and continue bringing the piston up until it hits the piston stop.
4) Mark this position on the flywheel/case
5) Bring the piston fully back down and up again to visual TDC
6) Insert piston stop and continue bringing the piston up until it hits the piston stop.
7) Mark this position on the flywheel/case
8) True TDC is halfway between these marks
Correct?
If not...help! If the steps are correct...help!
I follow steps but both my TDC markings come out at the same / very similar location on the flywheel...is that correct? For example, TDC mark 1 has the points locating pin facing 12 oclock and the other has it facing 6 oclock but my original marking is very close what i should be marking. I was expecting both measurements to be way off like the HHB example below....
Points locating pin at 12oclock
HHB example i’m looking at, the two differnt TDC range marks are far wider apart than mine.
