Big-end Bearing Replacement

The zx6r (2000 model J1) tracky saga continues ... as I feared at the xmas trackday the big end on #1 has definitely let go. At this stage #2 & #3 seem OK and although I can't easily check #4 without splitting the case, given where the noise was coming from I suspect it's OK. So, the question in my mind is, should I drop the engine, split the cases, remove the crank and get it machined (if needed, but I suspect it will be) and replace the big-ends (all four obviously, I only want to do this once!), should I wreck it (it's probably worth more in parts, but having bought the 08 it would be nice to get the money in one hit instead of dribs and drabs), or bite the bullet and get it professionally rebuilt?
Who's done this themselves? Any gotchas? I'm pretty confident mechanically and built this particular bike from a wreck, but I've not had a bike engine's insides on the outside previously
If you've had similar work done before who did it for you and how much was it? Would you recommend them?
If I decide to part it out is anybody interested in anything in particular? Noteworthy parts include:
- straightened frame. Not recorded as a write-off, last registered with single seat rego in Qld
- Racetech fettled shock and forks. Gold valves, anti-dive valve in the shock, eibach springs
- Ohlins dampener (across the tank 916 style)
- Factory-pro Jetted carbs
- D&D system (re-skinned end pipe isn't real pretty)
- Wet4U race glass, painted green with a black bellypan
- Woodcraft 42mm clip-ons
- Tinted double bubble screen
- Front and rear wheels painted green (originally red)
- Braided lines
Finally, if anybody's interested in a 'project' tracky 'as is' then I'm open to offers.
Cheers,
Dave
