Fuel. Generally as a rule of thumb, if the screw is located towards the front of the carb it regulates fuel--to the rear--air.

I've never seen a 99mm piston or heard of a motor made to run with a 99mm bore. But no, any old rings will not work. There are other critical dimensions other than the bore size. They have to be accurate in width and thickness. Some rings are tapered, some are flat.

It sounds like maybe this cylinder has been re-sleeved and then never bored to fit the piston.

The magnet is not visible unless you remove the drain plug.

Upon entry into going through the stock carb on my '06, I think somebody has been in here before.

Can anybody confirm the stock size main jet in a bone stock carb ? What about a stock pilot jet size ?

Are all the rubber O rings and bowl gasket available direct and seperate from Suzuki ?

And who would be a good OEM Suzuki parts mailorder place to the midwest ?

While I am at it, anybody know the Suzuki parts number for the counter seal keeper on the new bikes ?

Sorry for the questions, but I just got the bike and have no service manual, and there is no Suzuki dealer anywhere near me at all.

If I could "view" a service manual and parts manual on line that would help alot. ( anybody know, a PM would be great. Dont wanna violate the rules ??)

I'll check later. I have 2 PC drain plugs in our bikes.
Typical magnet insert:

Sprocket question

Been away from the DR for a while but want to put a new sprocket and chain on the beast. Am I correct in remembering that a 14 will give me a better slow speed offroad speed then the 15? Where is a good place to order sprocket and chain? Thanks

Yes, but the parts can be had for less money in a rebuild kit (see http://www.advrider.com/forums/showthread.php?t=528038).

Will these be suitible?

You might be making a common mistake DR owners make. DO NOT try to
break loose the Allen bolts on the rear sprocket ... not possible.
Get a socket on the NUTS on the other side of the sprocket. They should come right off. They are Loc Tite'd from the factory, but should break loose easily.

Bike Cover

I don't have a garage so rely on bike covers for some protection from the fierce western sun. Currently, I have the cover I used on my Concours, which is too big.
I originally had a cheapo unit which the sun broke down in just a few months. What bike covers are people using that fit the DR?

Procycle is correct about the rings- Shape, depth, radial dimension etc are all important.

And you said the rings were "too small"- which on a 99mm bore should be too big.

Define "too small" for me if you would. Are they too small to go on the piston? or do they fall through the bore when you put them in? And how did you come up with the bore being 99mm? Bore gauge? Snap gauge? We are only talking .0394" difference between 99 and 100- a ruler probably isn't going to cut it.

With the smaller 99 bore they should not go in the bore square without the ends touching or overlapping (both bad). Your part # looks correct- was the ring package sealed when you got it? Maybe someone sent them back with the wrong rings in the package. I ordered stuff from partzilla about 3 weeks ago...they had the order all messed up. Didn't send some stuff I ordered, sent some stuff I didn't order. One of the packages looked to have been opened and messed with. Luckily it was the "extra" part they sent- not one I ordered. Anyone need a master cylinder for a Honda?
