Yes she's a cb750 ! Sohc 4 cylinder:)
Deleted dpf egr and stage 1 map done today , clutch is slipping so im assuming some contamination. But engine is absolutely flying ,, mot tomorrow, have some range rover L405 sests to collect tomorrow, hoping a proper spin after mot might burn off whatever contamination is on the clutch plate , perhaps thier may be air in the system might give it another bleed failing that will sort a new clutch after Christmas, she's driving that's the main thing!
