Ok cool, well Pete / Z3i please let me know when you's want to sell your bottom ends/bare blocks and I'll decide how to go at the time you's offer me them if I don't use a std bottom end..
I recently fully rebuilt my bottom end (proper PY) - bored my spare block to 77mm, put new pec rods and balanced PY crank in with my OLD Wossners and the b**tard is blowing by horrendously - again! I am sick of it... The reason I stripped the first bottom end down was due to the fact that it had blowby under heavy/prolonged load and it sprayed oil everywhere - the original 77mm lump had one of it's Wossner piston's compression rings nipped into the land for some reason so I got it on a lathe and spun it clean so the new rings were slipping in and out nicely and this one piston in particular seems to be doing the same thing again. I think maybe it's been overheated prior to my ownership and it's molecular structure has changed as daft as it sounds as it keeps shrinking and holding the rings!... I could fix my own bottom end with one piston and a hone but I don't want to use old pistons again hence wanting a block that I could bore and use new pistons..
I did say mine was worn out to keep things simple but I could hone my current block out to new pistons I suppose as my current pistons were slightly undersize due to being used when I got it matched to each individual piston - the idea of getting a standard block was because they are are ten a penny and I could get some new Wossners and have it prep'd for the current one coming out to minimize downtime..
Z3i I will probably have a go at your forged bottom end if it has no blowby and you know it's good!
Sorry to waffle.. I struggle to make a point in writing!
Cheers!
