1700 X flow ignition timing

I wish to check the ignition timing on my Vulcan engineering 1700 X flow, with 345 profile cam.  Any one know what this should be, it currently shows 21 deg BTC at 800 RPM.

Waaaaaaaaaay too much. I don't what it should be exactly, but 15 degrees wouldn't be a bad starter for 10.

Try giving Vulcan a ring and they should be able to tell you exactly.

wot they all said.

Mine was about 10deg at 800 when i had a dizzy installed.

Total advance is probably more important 34deg at 3500, no vac advance fitted.

1700, A2 cam, 2*40's
