Morning all.
I have a 1971/72 oil in frame B50 it's come with a rev counter drive which l would like fit . It appears to be of the early type. Apparently there is a later type produced as well.
Can I fit this early type rev counter drive?
I gather the early type cable entry can possibly foul the frame but looking at a later type there doesn't look at to be much difference.
Any help will be most appreciated.
Happy New year to all
With the earlier type tacho drive the frame doesn't allow for easy routing of the cable next to where the cable end nut screws onto the drive. Maybe try it and see? - but I've seen several early tacho drives with a broken thread resulting from doing that. The '72 type drive allows the cable to start bending around the frame nearer to the engine - it works fine.
