So the mechanic says my bike bits should *finally* be arriving today (apparently someone sent 3 sets of rings for an I4 - wtf?) and I should be up and running again in the next few days, after a month off the bike. Man, I hope there are no further delays, 'cos I'm *itching*. Definitely will go easy when I first jump back on though - even in this much time the skills can rust a bit, and I'd only been riding that particular bike for a few weeks when it died. And given how crap the rings/compression apparently was, it should be significantly more powerful when it comes back (just call this the 50,000 km top end rebuild).
