Title: IMD pistons
Post by: DAVE BRADY on 22 May, 2024, 08:50
Hi,

Never heard of this company before.  Has anyone any experience of their products?  A set of pistons and liners for £216.99 seems a bit too good to be true.

Yes a mate bought a set last year and touch wood have been absolutely trouble free , from memory the oil control ring needed attention as it was to tight to compress to get in bore , I was a tad concerned the piston circlip was very close to edge , I think he use some original circlips for piece of mind , he has had no probs no burning oil ,

the piston he replaced was non branded in plain white box's and the seized twice he had bores honed and seized again I measured his clearance for him and they were double what is  recommended and still seized , he bought cheap and got what paid

IMD make good stuff, it's a shame they don't do more for BSAs.

Fitted IMD to my A10 in 2020. Fine, the only problem was with the circlips which were almost impossible to fit, the wire far to stiff, so used a set from a different supplier.
