Don't do it! Finish the build! Si, you know the pain and anguish I went throught trying to build that XRO works spec GSXR750 SRAD. Nearly eleven long years and at the end all I had was a very nice pile of parts! I'm sorry to say I made more money breaking the SRAD than I ever would of trying to sell the bike as a 'going concern'.
It's a very tough descision to make, but personally I'm now glad I did what I did by breaking the SRAD and then buying an NX5 RS! Hurrah!
Sorry I can't be of any more help, I can't help thinking about RS250's...
