I found some plans for a wood lift, which uses a basic floor jack for the lift. Pretty basic and seems like a good idea for those of us who have limited access to metal or the ability to bend/twist/cut/weld that much but can cut a straight line in a wood 2x6. Plans include the whole list of items you need, pipe, fittings, etc. Link shows a sportbike on one.

I found this, while looking for a lift, ending up buying a HF metal one on CL for a good price. A metal one will probably last a lifetime (depending on use, how built), but if you are looking for one less cost, lighter weight (easier to move), this might be an option.

The plans are pdf format. can forward to anyone who wants.
