How do I check the compression from the engine? So I set it up level and I had to add 500mL + bringing it back up to the top of level of the window. Here's the kicker.. I had only gone 1500km! The bikes is running so nice when I ride it, but there is something seriously wrong with that much consumption. I think I need the compression test and maybe a leak down test done? Should I talk to KTM? What do you guys think?
