Well, I got the bug to work on my VR this past weekend. The PO had let some things go and I thought it was time to correct them (and the wife was out of town at her sister's ) Issues: Front tire worn out Front Springs sagging and bottoming out unless I had max air pressure in the shocks Noticeable stumble when accelerating past 3500 rpm Headlight a little dim Too quiet (ok not an issue but something I wanted to change) Original fuse box with glass fuses (scary) First on the list was a new front tire and while I was there I replaced the springs with a progressive set from Skydoc. I also changed out the fork oil. Is this stuff supposed to be dark gray/black? The new Yamaha 10 wt fork oil was clear. Man! what a difference 1 hour worth of work can make, no more bottoming out and the bike tracks much truer through curves; no more pogo stick effect....wooottt. Now the stumble had me concerned so I went out and bought some Sea Foam and promptly added a healthy dose to the system. I also decided to replace the plug wires and plugs. Not as easy as replacing plugs on the wife's Jeep Commander but not as hard as the Vette so it took me about 30 minutes to complete. Well all I can say is the stumble is gone and the bike definately idles smoother (albeit a little low ~400 rpm). I think I need to service the carbs but I am going to wait on an area expert (Skydoc) before I dive into that tangle of tubes and such. Fixed the headlight by replacing the bulb with a Silverstar Xtra 9003 H4. I am amazed at the improvement made. Much better pattern and brighter white light even the low beam setting is much better. The mufflers were modified by cutting off the turn-downs and cutting out the end baffle. I left the inner baffle and I have to say I really enjoy the sound; not at all obnoxious but mellow and very authoriative. Very similiar to the low end growl of a Ducati (at least to me) but smoother. I may have the turn-downs welded back into place but right now I am enjoying it. Now the fuse box is still a work in progress but suffice it to say the glass fuses are history and in their place is are ATC fuses that light up when blown (pretty handy if trying to track down a blown fuse at night). I still need to fab up a holder but at least all the circuits are protected. All in all, a weekend well spent and the bike rides like a new machine. Heck it only has 29K miles on it and I hope to take it 100k more.
