Those are the ones I'm mentioning. Aren't the barrels completely un-torqued before those fixtures are attached? Seems like an afterthought to me. In case the jugs are bumped into or like you say, hope they don't leak. At that point why not just replace that gasket?
Can’t put the pistons back from the bottom of the barrel. You have to insert them from the top, that means to disconnect the conrods from cranck shaft, a big can of worms.
It could be completely different with the 2.5s (I'd like to know for when I get to where you are), but on the 2.3s you can replace the pistons going in from underneath. You may have already explained why not on the new bikes, and I missed it (my bad).
I just finished a Neville Lush piston and cam rebuild in ""record time"" with no prior experience. I had allowed myself a full five days during the Christmas holidays for the install. Well, now, more than three months later, I’m finally in a position to say, "job completed!" and share this story...
