fallenarch - I remembered that you'd upgraded your suspension - what did that whole package cost you, and where (what site) would you recommend a start when shopping around?
I took WAY too long to upgrade the suspension on my DR - I grew up on bikes and can pretty much ride anything, but I know I can ride it a lot faster and more safely with the suspension upgrades I made on that bike - I'm sure the 'Busa would be the same story. The biggest change was when I dropped in Ricor Intiminators (inertia valve) and changed the oil weight on that bike. No nose dive when braking, and soaks up the bumps perfectly. I liked it so much I just ordered the Ricor shock.
I know the 'Busa suspension is going to cost more, but if the difference is as drastic as it was on my other bike, I'm going to do it. I recently attended the "Texas Redneck Ramble" dual sport ride, and the night before they had a suspension set up class and a speaker that came in talking about suspension and he made a VERY good point. He said a lot of guys ride their bikes for a few years, finally pay for good suspension, then sell the bike a year or two later. He said - "buy the suspension first, and enjoy it the whole time you ride the bike". It was one of those "duh" moments for me. Why hadn't I done that??
I'm sure you've posted before on your suspension upgrades, I'll see if I can find the link. I'm sure the OP would appreciate it.
