1. Question 1: My KLR650 2002 is starting to idle at about 900 to 1000 rpm and needs a little choke around town for longer than usual to keep from dying (and me dying from embarrassment) at stop lights.
Its got about 14K miles and has been running perfectly before this. I have not had the valves adjusted since buying it new about 7k miles ago.
2. It has a 14tooth front sprocket and I drive it a lot on the freeway. I was thinking of changing the front sprocket (it was included with the deal about 7k miles ago, which should give me better gas mileage and maybe 5 more miles per hour at the same revs...is this correct? It does now seem to have some nice grunt down low and maneuvers well at low speeds...would this change drastically? and would just changing the sprocket be not a good idea as I have heard that you should always change both sprockets and the chain together (which would be more $$)?

If it's been sitting a while, you probably have varnish in the carb jets. Start by using Sea Foam, and if that doesn't do the trick, pull the pilot jet and clean it.
I've posted detailed instructions in previous posts.

First, turn it up closer to 1400 at idle.

You seem to be saying that you bought it "new" with about 7,000 miles on
it. I assume you mean "new to you", but just checking.
Are you sure that the valves *ever* adjusted?
Note that I don't simply say "checked". Checking and finding them to be
within spec is not good enough, they should be moved to the open end of
spec if you bother to open it up.

Steven,
Sorry to hear about the mechanical issues. I'm guessing your cylinder
also needs attention since the piston and rings are not serviceable.
That would eliminate the possibility of a used piston and rings from
another bike. So this might be a time to consider doing a 685 up grade
from Schnitz Racing. You'd have to get the 685 piston kit and then get
the cylinder bored to size matching your new piston. If you go this
route get a new headgasket from them along with all the other gaskets
you'll need. The mechanic/machinist will have to resize the headgasket
to fit the cylinder.
I don't know of any other options unless the cylinder is good and you
would be willing to try a stock used piston and rings. But that could be
a problem as you'd be hoping for a set that would match your cylinder
bore.
Can your mechanic or machinist there measure your cylinder bore
accurately so you could see if anyone has a used piston that might just
fit?
I've been told but have no first hand knowledge that the early rings are
not available new.
No matter what, it seems to me you'll be needing parts brought in to get
this situation resolved.
Best,
Jeff Saline
