What do we reckon about the other makes hepolite, IMD, Jp etc
no one has yet commented on IMDs. i've fitted them to the a10 and think they are great, especially with the 3-piece oil ring. i've noticed the oil stays cleaner for much longer and none gets burnt. when getting the liners fitted the engineer involved commented positively on their design (exactly why went over my head). the down side is they are only available at lower compression and i can certainly notice the difference on the a10. strangely, the other possible down side is they are light so you may want to rebalance the crank (hence its not just a top end job).
i don't quite share trevors enthusiasm for JPs but only have had a couple of attempts with them. from memory they need to have wide clearances and so before long slap around a bit when cold. fully agree the rings don't suit our bikes. there are better options (tho few in +080, which JPs will do)
