I took my 99 KTM200 out this weekend and noticed some problems with the hydraulic clutch. The clutch action at the lever seemed fine when the bike was not running, at idle, or just riding at slow speed. But when I got the bike up through the gears at a pretty high speed and then backed off of it, the clutch seemed to loose the full range of action; it was very loose through the first 1/2 to 3/4 of the lever action. But soon after that it would return to normal. I think the first thing I will do is back bleed the system and hopefully remove any air that might be in there. Has anyone had this problem before or have any ideas as to what is casing it?
