I bought one for the Jackal (from a different supplier), but returned it as I had a couple of concerns and not being an engineer I didn't feel like taking any chances.
The smaller diameter oil (holes?)in the pan were 0.5m smaller diameter than the stock pan and the large one was 2mm smaller.
The pan fitted ok, but when the relief valve was installed it hit on a gallery in the crankcase meaning the fasteners didn't quite line up. Probably shaving a bit off somewhere would have helped but...?
This led me to think that there are some differences between the 1000 and 1100 Calis (that this apparently fits). Certainly the 1100 has a larger stock oil filter than the one supplied with this item.
