785 sleeve or re plate
The price to re plate is the same as re sleeve if I re sleeve I can bore to 780 Pistons ? Or is re plating better and going with 750 Pistons ?

This doesn't answer your question, sorry, but is a 785 a 750 with triple pipes? Guess I always thought a 785 was a 785cc.

I would replate in my opinion and you can't go with 780 pistons it messes up the port timing to much from what I was told ,don't get me wrong you can do it but it will never be right like they say anything will work but I like it right not rigged

If you put sleeves in, it also takes up space in the transfer and boost ports. IMO this is a poor idea on ANY cyl that was originally plated.
I can get cyls plated, get you new pistons, etc if you need. Feel free to call the shop 608-743-1305 if I can help.
Should add, It is also my opinion it is better to run actual 785 pistons, and be sure to have tolerances set up properly, as all that is available is Wiseco, they are a forged piston, and will grow more than a cast piston.

Wiseco's are out I ride in cold water and have had problems in the past . Are 785 piston still available or do I have to use 750 and bore for tolerance difference?
