CB750 Big Bore kits

[RupertB]

Having decided (almost) that the 810 pistons in the CB won't be reused in its rebuild, I was going to get a set of Wiseco 836cc pistons. I have heard of Wiseco and I think they are OK (opinions please...)
However a well known internet auction site has now thrown up a set of 'Cycle X' psitons which take it to 850cc.
Any opinons either way on Cycle X versus Wiseco please?

For in-depth discussion on all the options (and loads of people who have actually done it), go to the US site and look at the Performance section:
