Had my bike serviced, now I gotta learn to ride it again
Had my bike in to the dealer for it's second valve adjustment last Friday.
The first valve adjustment was at 15k miles by an independent mechanic, and when he sync'd the TBs he backed out the adjuster screws a bit which made throttle response much smoother--at least off idle, or for low throttle inputs.
The last service, at 38k miles apparently the dealer went back to the factory set up. At first I thought the bike was more responsive, until I realized they just adjusted the factory snatchy throttle back in. Today I was getting used to riding it again. I've had a smooth throttle for just over a year now.
I never bothered with the TPS mod on this site before, but now I might--it sounds easier than re-syncing the TBs with the screws backed out further.
FWIW at the 1st valve adjustment 7 valves got adjusted. This time 3. Both times the tech adjusted valves that were near the limit, not just out of spec. I didn't get a before/after report this time, but the 1st time most of the valves were close but still within spec.
It looks like the wisdom I gleaned from the forums one this was correct: do the 1st valve check early, but after that the factory service intervals are good. At least that seems to have worked so far.
