it appears to be timed correctly, as the index mark is just right of the top stator plate bolt and aligned with the right edge of the case casting boss.
remove stator plate and the seal pops out! yet a whole nuther deal on the main bearings as the cases must be split.
Would be the same as later years if you can find that. Not that it is not going to change with variables such as fuel and altitude/ air density(temp).
45/125 is pretty standard place to start with the Kiehin jets. needle somewhere near center groove or one notch down and airscrew between 0.5 and 1.5 turns out for best running.
standard enduro pants work fine, shirts too for that matter. spend on proper trials boots and gloves. helmets are mild to wild on the budjet, just depends on what fits the noggin well really.
5W is the one, however you do it you will need to pump the air out of the damping cartridge in the right side fork and assure the fluid level is correctly measured on the Tech forks.
no real easy way on them
