Compo, I can get my hands on something like that from a friend who does drainage etc. but not today so I've used mine again which does self level and has a cross but doesn't tell you angles.
The first thing I did was set a piece of 9mm glass level and set the bottom yoke on it.
It's not too clear on the photo but there is a decrepancy between the lh and rh fork tube clamps even though the centre tube was vertical. It also rocks. Here's a video. The laser can be seen better also.
https://www.dropbox.com/scl/fi/cmu48sj3 ... y0ov4&dl=0Al, I could get a measurement underneath the swingarm pivot and it was 0 but with the bracing and welds around the headstock I was't confident with the reliability. I did get 88 both sides which makes sense but I could alter the reading by tilting the phone so not conclusive.
Next, refitted the lower yoke, set the laser to yoke centre underneath and also to the centre of the frame at the rear, then set the horizontal.
As can be seen the rhs is higher than the lhs and the headstock is tilted towards the left at the top (As it's looked at in the photo). I wanted to check other areas of the bike so set the laser up with the horizontal line set on the fuel tank mounts and the vertical on the top of the headstock.
With the lower yoke centralised I also measured the distance from the tail fin mounts to the slit on the fork clamp. There were within 2mm of each other. 119.0 cm and 119.2cm.
Z1Streetfighter, if you get a chance could you do this measurement please? Rear of the tail piece mounts on the side tubes to the top of the slit. Cheers
Another photo showing the top of the lower yoke tube's offset due the headstock. Again datumed to the underside of the lower yoke.
Dropped the top yoke back on and the forks in, set the bottom yoke central then lasered each fork using the top of the stanchion as a ctr point.
So unless someone can see a flaw in my methods I think the headstock is definitely kicked over and the lower yoke is potentially bent as well, therefore the top yoke also. Now just got to work out what to do next if I can't find a frame straightener. I have access to trolley jacks, chains, barn walls that are 50cm thick and tractors, steel bars.......just can't see it is possible without damaging some other part of the bike.
