My current jetting is perfect for the entire rev-range and at all throttle positions...
How's the jetting going?
...because it's going nowhere until I sort the clutch!
Got a lovely big SIP clutch order in this afternoon though; banded SIP sport, Sip CR80 with Sip plates (I'm wary when stock is low, but after order it said immediately dispatched on confirmation, so thanks for correction, Jack; I'd have missed that), choice of (16) standard or L springs, reinforced circlip.
93402000, 93081900, 28960300, 93120100, 93182000
Thanks everyone for chipping in; I'll update when stuff arrives and/or when I commence surgery.
