Well it's back and looking as shiny as ever
Managed 20 odd miles tonight and all seemed well. Gearchanges are smooth and power seems unaffected by the engine strip trauma, looks like they got all the bits back in the right place.
A few scratches I didn't have before (oddly on the front of the crankcase) and a bit more gasket sealant oozing out than I'd like but I can rectify that easily enough.
Suspected a head gasket leak after ten miles but I think it's just assembly oil so I'll keep an eye on it.
The biggest improvement has been the removal of the screen. I took it off after my small accident and haven't put it back yet. For such a small screen it must've reflected back lots of engine noise because things are a lot quieter now.
All in all I'm glad to be putting the miles in again and look forward to finishing the running in, 534 miles so far.
