Hello,

For those who may yet be converting their older 910's to HTD cam drive I offer the following. In the process of setting up various drives for the engine to go into my restored S2 I have observed that the drysump 910 crank on hand does not permit either HTD or original cog to seat to the point where the cambelt guide flange is trapped tightly. I have carefully drifted the cogs home and find the flange still freewheeling on the 910 crank in either case, something I'd not tolerate. Either cog fits perfectly on the original S2 907 crank. FYI.

Cheers 

I may have sounded a false alarm here, having looked it over again last night and not finding what I thought apparent previously. Relieved to be wrong in this case.

Cheers
