I HAVE JUST AQUIRED A 99 SCRAMBLER 400 4X4..CALL ME DUMB BUT I CAN NOT FIGURE OUT HOW TO CHECK THE OIL IN THE CRANK CASE?? THERE IS NO DIP STICK & THE BOLTS I HAVE REMOVED ARE SOLID BEHIND..MYBE IM JUST BLIND BUT I CANNOT FIND IT..ANY HELP WOULD BE GREATLY APPRICIATED.. THANK YOU..DG

 

Pull the seat off an look strieght down past the carb would be on the right side of the carb when look at it from behind .it is very hard to see it down there. An it is very hard to get out too. The best place to check the oil too is there is a both on the front of the motor on the right side of it coming stright out it is the bolt for when you fill to make it level so if you put to much in it will drain to the right hight.

 

It's oil injected =)
You could always mix a little two stroke oil in with the gas too. I do just to be on the safe side.

 

Forgot to add that this oil is a counter balance oil. I was recomanded to use a synthaci gear oil in it from someone who has a HPD built motor
