If you look at the ad for the £9.00 ebay ones it says not recommended for efi bikes. I have the CPC ones fitted to my efi bike which are the same spec I think as the DP kit ones but a bit cheaper and have had no issues with them so I assume they are much better quality. But with the risk assessment in my mind completed I would probably fit the metal ones now in preference unless I had a carby bike in which case I might risk the 9 quid ones. The plastic ones on my 748 have also given no problems in the 15 years of ownership and they are original CPC ones too.
