I ride year round and do mods on my winter ride in the summer and mods on my summer ride in the winter. I was using my 2K VFR in the Winter, but since I bought an 03 R1 last March I got behind on the 2k VFR maintenance. I did a lot of work and mods/upgrades on the R1, and used it most of the summer. I plan to use the R1 in the warmer months for commutes, aggressive runs and trackdays. I recently picked up an 05 VFR which I am using this winter and will do some mods and maintenance in the summer.
Winter Mods: Yamaha R1 - Velocity Stacks, PC III, Dyno tuned, Yoyodyne slipper clutch, re-cover seats with custom flame leather and gel pad.
2k Honda VFR: Chain & Sprocket, Iridium plugs, thermostat, anti-freeze flush and change over to Engine Ice, Stainless Oil filter & oil change, convert to synthetic oil (Shell Rotella T), Fork oil change and seals *(maybe new springs), recover seat, brakes pads. Not sure if I am going to be selling the 2k VFR after the summer, if not then I will also do the wheel and swingarm bearings, and tapered head bearing.
Summer Mods:
05 Honda VFR: Turbo City Fuel Pressure Regulator, Motovation Sliders and weighted Steel bar ends/sliders, CNG Levers, Galfer Stainless steel brake lines, Stainless Oil filter, convert to synthetic Oil (Shell Rotella T), Flush Anti-Freeze and convert to Engine Ice, Zero Gravity Double Bubble Windscreen, Gel pad in seat, Freeway Blaster horn, and Skull graphics kit.
I am selling my Yamaha YZF600R and will only be changing the oil, anti-freeze, and brake pads. The YZF 600R is a nice bike in excellent condition, and only a 600cc bike - reliable and cheap to maintain. I am a Motorcycle Club member and two of my club brothers will be working on my old 94 Suzuki Intruder so we can ride it this Summer.
