600SX Specs
I have a 2000 Yamaha Service Manual that states the SX600R production Specs are MJ #1 136.3 and MJ #2 and #3 are 133.8. I don't think it changed in 2001.
I know the SX700R is the same for 2000 and 2001. I think Mr Sled may have mis-typed the first 136.3 to 136.8 but everything else looks right to me.
