When I first bought my '05 FZ6 I noticed a little bit of surging at idle. No big deal I thought, just a little out of sync, and rode it. Lately it has a stumble off idle, especially with just a blip of the throttle, and sometimes it "misses out" on hard acceleration, but eventually smooths out sort of like an engine loaded up and finally clearing out. The two problems don't occur all the time. I'll say most of the time it's just fine. Well, today, riding in town accelerating away from a stop I noticed the roughness off idle and also "pinging". Any ideas what might be the problem? The roughness, I'd suspect injection, but the pinging I'm wondering if there's an ignition control going bad. The bike has just under 29,000 miles on it. I have only had it about 700 miles and it appears to have been well maintained.
Thanks, in advance for thoughts and experience you might have had with anything similar.
