4D, thanks for the mail last night. You are right, your L-bars are a very different shape than the ones that i have (at the rear peg mounting pt). I mailed Ventura yesterday and here is there response -
""Thanks for your enquiry. The part numbers recommended for your model should be D008/B and PF16/B. This rack may not be reversible and unable to be used facing forwards, however if this is your requirement you could exchange the PF16/B for a PF14/B which has longer legs at the base and would give clearance.
The design has always been to keep the carrier low and in line with the rear seat for all high speed sports bikes, which means the rack can often only be used facing to the rear.
I hope the above helps.""
No, not really..... I have replied again today including pictures so, i'll see what the response is tomorrow.
This is the pic from the ventura web site of how it should be mounted on a 996BIP (no pic for the 748bip). Is this how you use it, or do you mount the rack over the back seat? (same as Antonyes' question!!)
