A good bender will cost yah a few bucks but can be moeny well spent. Cheap ones usually are a pain. Don't get a harbor frieght pipe kinker for pipe and hope it will work with tube. There are afew who have gotton them to work BUT its more work and still a good risk of crushing a tube.

Many times a local race car chassis shop can and will bend tubes for you. Just be sure you know what you need and if the tubes even already marked so its quick for them the cost can/may be quite cheap (check around to see what they say). That may save you a few bucks to put towards the build.

While I got a chuckle out of Yoshis comment IF you happen to not go that way the first thing I would do is look at every buggy out there. Gotta find one you like the looks of.

As for a motor anything realistic. You need electric start and you want reverse if at all possible. A big Raptor660 or better yet a 700 motor has the reverse and electric start. for a small buggy in the woods its a good choice. But if your into all out dunging it may not be quite enough. Where you ride and how will dictate whats a better engine for you than others.

If you buy a motor try to get one you can still see run or buy from a place with a good reputation if at all possible. A good deal is no deal if the motor happens to be junk or you get a good deal but then gotta hunt down a bunch of parts (fuel pump, ECU, etc) that all add up costing you more than a running wrecked bike or sled etc. in the first place.

Most plans can be altered enough to fit this or that engine.
