This R1 had its carbs’ funnels missing, which went some way to explaining why it was running terribly. Once we’d sorted all that out (we sourced a complete replacement bank from Portugal) and set them up on the Dyno it still wasn’t sweet, and refused to idle cleanly. We started to get get a bad feeling, and a quick examination of the breather pipe (simply pulled off the back of the airbox) showed it pumping out lots of smoke…
Ouch. Blow-by the pistons engine was the cause – the engine was simply worn out. So the unfortunate owner had coughed for a set of carbs to get the bike running on four cylinders, only to discover that his engine was completely knackered.
Sorting the carbs only led to bigger problems – this R1’s engine needs a complete overhaul.
