Hi Stevie.P, I have a subscription to Haynes. But I noticed that for some procedures they are not very specific. For example, in the Tiger Gen1 service manual the values for Inlet and Exaust are:
Inlet: 0,10 - 0,20mm
Exhaust: 0,275 - 0,325mm
And these values are different for GEN2. So Haynes is excellent for most procedures, but if they were more specific with some information it would be perfect.
