I finished my subframe porject this weekend.  I had never welded tubular steel before, and it was quite an interesting experience.  I am in no way a pro welder, but I can make some decent beads doing butt joints and t joints and stuff with a MIG.  I can get some really nice "dimes" doing oxy/acetalene too. I couldnt get a good bead to save my life doing this.  I overwelded a lot and ground stuff down mostly.the link for the site to view the whole project is www.fotki.com/cbrf23/subframeI would post pics here, but pics hosted on that site never seem to work right when I post them in forums.Thanks to those who helped answer my questions!  I got a few more questions about welding aluminum that I'll be posting later.
Reply:looks good im not a sport bike guy (mywife wont let me) choppers are my thingi know why i need to cut a frame and move stuff but ,did you do all that to make that seat fit? or is there more to the bike than what the pic's show?anyways good job looks like a pro did itride safe chuck
Reply:Good job. Looks much cleaner. Do you think you saved any weight?
Reply:Thanks guys.  I definately aint pro, lol.I love choppers too, but I cant afford one, and I have more fun riding a sportbike right now. I did it to use that rear tail section and to clean up the back and give more clearance for a custom dual exit undertail exhaust that I am going to be making.  I dont really think I saved any weight, because the tubing is 8 gauge and stock is like 14 or 16.  So even though there is a little less metal, it is thicker.  If anything I may have gained a few ounces, but I do know it is way more rigid then the stock subframe - so I'll take that trade off.  I figure whats a few ounces, when I could gain or loose a few ounces off my body each week?
