Remember that "playing card" sound after the bang?

[SnakeyesTx]

I had that piss-poor idle when cold, and the bucking at lights, and a few days ago I heard a *bang* by my feet then heard this buzzing noise like a playing card in the spokes of a bike wheel. Naturally the noise increased with speed, but vanished at below 30mph. My dad was with me at the time and swore I ran over something, but unlike him, I'm not half blind, and I scanned the rear-view mirror immediately after the bang. I had a theory it was the guibo exploding, and that the nylon cords were blown through and smacking the floor. I couldn't have been more right. This is what came out the next day :




Basically, the bucking was exaggerated by this little #$^@er cracking apart. (I think I solved the bucking as well - timing chain tensioner was broken but I haven't had enough cold days to confirm it). The bang was the rubber flying apart along the cracks, and the buzz was obviously these nylon cords flailing around. 54 dollars for a new guibo, couple hours of heartache due to distractions, and problem solved. Thought I'd share this with you in case someone elses looked worse than this one

that one is pretty bad, saw worse though. I wonder why it went with a bang though, I could see under a hammer the peddle session but cruising?
