1500cc motor

[Network Legend]

Hey all,   Just is still out, need to take motor off, but it would appear that it's a main bearning issue on the bike.   Oh well, so it's going to be a while before it's ridable, so I thought I may do some engine mods before winter.  Well, I've heard about this 1500cc PCW (PWC?) motor out there.......anyone know about it?   Or how about what you would do if you had to rebuild and wanted some more ponies out of it?   Thanks!   James Moore Atlanta
