I don't remember the quantity but if you go to Yamaha Auth. service center they have a small plastic box of fork oil labelled as Geniune Yamaha Suspension oil and the whole box is poured in one fork. So you will need 2 such boxes if you are servicing both the forks.

Hello
The main jet size should be 2 wire drill sizes larger (measure to the closest wire drill size as a starting point) to start for a 4 into 1 exhaust system, There is no one size fits all, you start with drilling it out the 2 wire drill sizes (set is 1-60) and see how it runs. Do not go more than 2 drill sizes larger as a base line. I have done this on at least 5 of my Japanese bikes.

did you turn the fuel on?

If the clutch is working as it should, the shifting problem is unrelated to the clutch. The bike has a bent shift fork or two. It is costly to fix.

Have you checked your altenator? With a fresh battery it will run for a while but if your altenator dosnt work your battery will drain and bike will die. Also the bike is not made to run on a battery so if the altenator is weak or or bad you are not getting enough juice to your plugs , thus causing sluggish ride.
