come and see me on Sunday I will try tune it for you. btw make sure clutch is set probably!
if you could help me out on Sunday , that would be fantastic.
bit more information:
- have always been using plug P6 (that's what I have been told to use at my lhs when I bought it) so that's all I have at the moment, I will buy some P7 plugs before the weekend if I get a chance
- bottom end needle untouched, sems perfectly flush
- top end needle is at 2.2 turns from full close
- pipe is OS Tuned 1050 SC
- clutch ! oh gosh ... this is a whole another story, I have spent 1.5 hour on it last Sunday but not 100% sure if I got it right, I have a feeling that the black spring may be too hard (with yellow shoe) so yeah this may need more work
