Hey, I've been working on my recently purchased (used) '00 XR650R. First of all, the bolt that holds the subframe to the main frame, at the top, where the subframe pivots. It has no nut on it!! The bolt comes in from the right side, sticks through but no nut. It appears that the subframe is slightly marked from a washer or something. Furthermore, the bolt is tight, but hardly sticks out more than a 1/4 - 3/8". My manual doesn't say jack. Is there supposed to be a washer/lock washer/nut on there!!!!???? Second, what's the deal with the dipstick hitting inside the frame as you screw it in? Mine is kinda twisted because every turn it hits and then slips past the frame. Obviously, straight dipsticks hit too, or else mine wouldn't be twisted. Any fixes??? Finally, I've got the open intake manifold, airbox restrictions removed, White Bros. pipe, bigger main jet, and needle in 4th position. My idle kinda surges, it doesn't keep a steady idle. If I blip the throttle, it idles down, but only for a minute, then it surges back and forth. I've checked thoroughly for airleaks, and can't find anything obvious. I'm pretty sure my stock 68 pilot jet is too lean for my setup. Is the "68s" pilot I've read about any richer?? Should I go up a whole size bigger on the pilot?? Any help would be greatly appreciated. Thanks in advance.
