Need help figuring out what is right and wrong here. I’m reading through the Chalkdust II and come across on pages 70-72 where someone made reference to typos in the service manuals referencing cylinder positioning at TDC when inspecting valve clearances. I made the changes in my service manual as instructed and hopefully those are now correct. When I got to the next page or so the person claims there is another typo referencing “Specified Valve Clearance (Mean Value=0.125mm (Exhaust), 0.145mm (inlet) whereas the person claims the actual “mean value” for the exhaust should be .215 and not 0.125mm. I’m just wondering where does one confirm that this .215mm is the actual “mean value clearance” for the exhaust valve? Also on that page in my service manual, it gives a formula for figuring out what your replacement shim size should be with a formula of a+b-c=d whereas a= present shim thickness, b=Measured Valve Clearance, c= Specified Valve Clearance (mean value= (0.125mm printed or .215mm as corrected by Chalkdust II article and 0.145mm printed (Inlet), d= Replace Shim Thickness. Furthermore, my service manual gives an example of how to use formula with given values of: 2.300mm= present shim thickness- value “a” in formula, 0.31mm- measured valve clearance- value “b” in formula, 0.145mm value “c” in formula, and it comes out as 2.465mm as Replace Shim Thickness. However, the next sentence below it states “ Exchange the shim for the 2.475 size shim”. Is this last sentence also a misprint in the service manual as well because that does not make sense to me. I’m going to be doing a valve check soon on my bike soon and just want to make sure I go into it with the correct info and knowledge.
