Finally decided to give the old girl the once over. Had been running the 17" rear wheel off my spare bike for a while and decided that fuel economy hadn't changed a bit, so I went back to the original 16 incher. While the wheel was out, I went digging further after reports of the driveshaft actually stripping the gears off them and found this.-
The teeth weren't worn to the point of having a razor sharp edge on them, but they had a definite step in them which probably would've been through the hardened faces, so future life expectancy was drastically shortened.
To date, all I'd done with this was pull it from the housing every 70,000 klms or so, fill the female drive socket with grease, and plug it back in.
this time, I actually cleaned all the old grease off it, and saw how much the splines had been worn. To be fair, the bike has just clocked over 300,000klms and this is the original shaft, so that's not bad mileage for a sliding joint that moves with every movement of the suspension. I went out and pulled the shaft from my donor "E' and saw that it was in nearly new condition.
While all this was happening, I removed the swingarm and checked the tapered roller bearings in the pivots, washed them out, repacked them and reassembled as it all checked out ok.
Repacked the diff flange with moly grease and reassembled, then refitted the 16" wheel.
Took it for a run to work today, and all I can say is, "What was I thinking?"
The acceleration off the line is awesome with the lower gearing, and overtaking without downshifting will be something I'll have to get used to doing again. Engine braking is much stronger, too, which will take a load off the brakes in the long run, which is good, eh? Plus the fact that these motors love to rev. I can feel it, alrighty!
Combined with stripping off all the rack, panniers, towbar etc. which has made the bike about 30kgs light er makes it all the better. The fairing's coming off this weekend, so I can take full advantage of the newfound, old performance.
Roll on Sunday!
