If your front engine mounting bolt hasn't been removed and re-greased/copper slipped for quite a while then it could be worth checking.
I bought a low mileage - stored for years - Cali 1100i project bike approx 3-4 months ago and checked the two main long engine bolts (I have come across at least one rear seized bolt before now) a couple of weeks back and found the front one stuck fast. I tried heating it up (plumbers type gas torch) and WD40 with no luck and even a heavy lump hammer had no effect.
Left it to soak with a mass of WD and tried again a few days later with more heat and initially no luck at all. Tried again with a lot more heat everywhere including the frame and got a fraction of movement,so with more heat came more movement and so it went on. Still took the lump hammer and a drift to finally shift it completely.
Now that's free I'll be happy to take the bike apart if anybody is interested in a 96' Cali frame ( rails chopped off behind shock mounts) with V5 for not a lot of money. Got to decide what else I don't need,but definitely the swingarm,side panels,foot levers and ........??
