    Thanks I noticed that it seemed the same all the way through Commando production.

    Living in the UK I sort of forgot OB. But fact is my question was whether it was BSF or CEI. BSF is 55 degree and I thought CEI was 60. As I needed a tap wanted to get the correct one.

    If it is an American cam (Megacycle) it would be 1/4-28. Most EI kits come with both bolts for the magnet pickup, based on what cam you have in your bike.
    Cheers,

    Well problem is I have a nice array of possible bolts none of which will play ball. Next is to have at it with a starter BSF tap. The bolt that came
    out is clearly not the correct one. Ill report back...

    Reporting back: DPO apparently buggered the threads or at least the first few. I had at it with a starter tap and was fortunate enough to get it in.
    Second tap cut all the way down. The final tap wasnt happy about going in past the first thread so I wisely quit whilst ahead. A new bolt went in
    well and although slightly loose in the early threads it is fine as you go deeper. So solution is to use a longer bolt and Im a winner.
    Of course the bonus was I didnt even have to take off the timing cover!
    Huzzah!

    Well SOMEBODY plucked the duck...we all have made errors that were sold on or swept under the rug. Part of the learning process! :)
