After changing the oil, filter and chain, I went for a ride to town to pick up some half and half (15 miles one way)and to see if there was any noticeable difference. Other brothers had smoother shifting, less engine racket, smoother clutch operation and probably better sex from a change to full synthetic oil and an o-ring chain, but I'm ever the skeptic.
I'm a former army aviation maintenance officer and post maintenance test pilot so I'm very sensitive to vibrations and noises and I have found the T-Dub to have a noisy valve train and quite a bit of high-frequency vibration from around 40 on up in fifth. Also, the clutch sticks in the morning or after the bike sits for a while when it's cool - I always put it in gear, pull in the clutch and rock it back and forth until the clutch breaks lose before I try to start it, always starting it in neutral. If I didn't do this, the engine often died as soon as I put it into gear, and it would almost always lurch forward slightly when I shifted to first even if I did.
Like I said, I'm a skeptic - I've never been the guy who thought my car runs way better after I washed it, or went oh so much faster with the brand new fuzzy dice on the rear view mirror, but the differences in my T-Dub after these two simple steps really surprised me. It shifted much more smoothly going up or down (no more CLUNK when I went into 1st as I approached a red light), the clutch was smoother (it was never really bad but now it's like butter and keeping it in the friction zone is as easy as on any bike I've ridden - I was a motor officer with a Bay Area PD back in the mid-70s), the engine noise was noticeably reduced and the vibration at the hand grips had moved from 40 to 62. Let me tell you, if I didn't have a half pint of half and half warming in my saddlebag, I would still be on the road it was such a pleasure to ride.
Now, if it stays that way I'll be a real convert.
