Thanks Ash I shall give that a full read tomorrow. Had a quick look at it and left/right of the engine is as viewed from the front in that write up. That may be the reason as I am doing it as per sitting on the bike. Could it be that simple, lets hope.

After a real good look at this problem I think I have found the issue.
First of all left and right is as sitting on the bike not from the front as per Ash's MCM 500T article. It was easy to verify as at the LT mark only one piston is at TDC so that's the left side, confusion sorted.
The problem is that the right exhaust valve will not set when it should. For those that were reading my build thread you will know that the cam and followers were reground by Newman Cams. Looking at it (hard to measure with it fitted) they have taken way too much meat off the right hand exhaust follower and taken it way out of tolerance. So a new follower is required at £105 delivered (ouch) to fix the problem.
The settings are therefore as per the Clymer manual as mentioned earlier.
Anyone got a good condition 450 cam follower going spare. Cash or donation to the site waiting. Cheers.
