check this place out, they will make life better for you--> http://www.skycycle-salvage.com/
we had another small field trip the other day, this time up to Fitchburg, MA. hidden amongst the rotting mills and fog up there is a gem of a place for anyone into jap bikes, especially those who like to cut and paste their bits with other bits. i really like it here, they have parts to things you've never heard of, piles of every part of a bike AND imagination. every time we've been up there with some half-assed idea and an even shittier description of what we need they've been able to decipher our babble and steer us towards progress.
i took a bunch of pictures and will post them every so often so keep your eyes open.
