I've now been driving my "new" 5th gen for a few months and I'm planning to do a bit more than regular maintenance the coming winter. I've read through a ton of related threads including GreginDenver's excellent sticky and I've come to the conclusion that even though mine is low mileage, 20 years is still 20 years and I want to at least check/replace some seals and gaskets and give it a good cleaning once I'm taking it apart anyway. There is nothing actually wrong with the bike although I've never ridden it new so what do I know One thing I have noticed is the brakes. According to previous owner the fluids have been changed once every two years but still the front brake feels a bit spongy especially when driven a bit harder on track. Rear brake lever is quite stiff but works. Clutch engages very late, at the end of the movement that is, but doesn't slip and otherwise works ok. To my knowledge the electrics are original but there is a small computer fan on the RR. The point of this thread is basically to see if there are some things I've missed that I'd need to take a look at while doing all this. I'll list below what I've thought and gathered from other threads. The bike has around 40k km / 25k miles on the clock. Brakes - new brake lines, going with stainless steel - taking apart and cleaning all brake calipers and rebuilding with new seals - the same for front master, front slave and rear master cylinders - even though rotors are not alarmingly worn, I'll go and replace them too - new brake pads and fluid obviously Clutch - same as for brakes, take apart / clean / rebuild - I'll probably change the springs for a bit heavier EBC ones - slipper clutch would be nice but they're prohibitively expensive Electrics - I've purchased a VFRNess so installing that - mosfet-type RR - checking and cleaning connections Suspension - doing something for the soft front, thinking Andreani Misano cartridges currently - rear already has a Wilbers shock so only adjustment needed there Other stuff while I'm at it - new coolant hoses - new thermostat and o-rings - maybe cleaning and coating the exhaust headers - having injectors serviced - starter valve sync - new spark plugs Maybe - PCV - Pazzo/ASV levers - Helibars - do the flapper/snorkel/PAIR valve mods make sense on a '99? Feel free to comment if there is something else that would make sense to check/fix while I have the bike apart.
