Evening.

for once I am just sharing rather than asking for help.   Whilst looking for torque settings for the clutch nut and primary gear nut I came across this pdf.

davestestsandarticles.weebly.com/uploads...8-73_rt-dt-whole.pdf

didnt answer my questions but an interesting section on timing.  I have heard and seen 2.9 and 2.5 mm BTDC.  

but this pdf says RT1-F  1.9 +0.2 -0.5 mm BTDC with governor wedged open.

this probably isn’t news to you all but it is to me.  Have people seen and used these settings?

anyway just thought I would share and hope not wasted your time. 

many thanks, ian


 

Good catch!  My take is 1.9 is a typo in that doc.  Yamaha and aftermarket literature unfortunately has many typos.   

Note that the actual timing procedure explanation in that same doc uses the "RT1-F" as the example and states 2.9mm there.

Cheers Mark,

I should have looked deeper before posting. Cleared up anyway.

Always worth asking.

Thanks
