I'm thinking of setting the "adjustor" (i.e., item 28 in Partzilla link) so that the "bottom" of the throttle is higher. Hopefully, this will increase the idle speed and keep the engine from dying.
Adjusting the idle speed idle stop knob (part #28) is no big deal, but the real problem is it seems to be running way to rich. Are you sure an O-ring didn't drop out or something? I'll take a look at the parts diagrams.

It looks like there's an O-ring, a spring, and a washer that sit above the pilot screw. There's an O-ring above the main jet. If any of those got lost or put back in the wrong sequence when you were putting things back together, it would mess up the mixture. I would focus on the main jet first, because a messed up mixture on the idle circuit (the pilot screw and related parts) ought not to make it run so rich that it fouls the spark plug...that would just mess up the idle mixture.

I'm sure I assembled the pilot screw correctly.

I didn't notice an O-ring above the main jet. If I lost that, then I'm SOL. I can't even go back to the original main jet if I wanted to. Oh well, $306 for a new carb.

Negative. Just order another O-ring if that's the case.

Nice. Does it have a kick start?

Yes, Kick start only. Same bike as DR200.

If I ran across one of those, I'd snap it up in an instant.

Took the carb apart today and the washer (it is not an O-ring) is on the main jet, so that is not the problem.

One last thing, when I ordered the jet kit I asked if it was necessary to have the muffler modified also. I was told it was not, so I am still using the unmodified stock muffler. Is this correct? Do the new Kientech jets need a muffler that flows more freely than the stock muffler?

Thanks.

I ran the Kientech jets for a period of time with the unmodified muffler, and there was no problem. Keep trying, there's got to be something we've overlooked.

Just installed a DG Performance Exhaust

Just installed a DG Performance Exhaust. I chose the oval version because I thought that the shape would be a little closer to the OEM than the round version. Delivery was rapid, I ordered it on a Friday and got delivery on Monday. Upon opening the box I was impressed with the build quality of the exhaust. Nicely welded and it this is a quality piece of equipment. Installation was pretty straightforward but not a perfect fit. It is a very very tight fit on the lower mounting point bolt. I had to trim the rubber spacer on the plastic side panel to accommodate the width of the exhaust. I'm still not sure if I'll have to trim the side panel to keep it off the muffler to prevent melting. When I fired it up after installation my first reaction was Wow! Sounds like a 400cc now. I will say that if you are looking for quiet performance this is not for you. If you are looking for aggressive thumper sound it is beautiful music. I would recommend the DG Performance Exhaust. It's far cheaper than the FMF and is available in both round and oval versions. Bike's a little dirty from daily riding but here is a picture of it installed.

1.) how do you drain the gas properly?

I just figured out the fuel petcock doesn't have an "off" position...

the fuel line to the carb is also pretty short, so I was going to yank it off the tank, and quickly put on another hosed (piped into a gas can), then let it drain...might get a little messy, so I was hoping there's a better way

2.) what size is the fuel line?

I want to extend the line and install an in-line fuel filter in case any residual crap from the old gas gets into the carbs

3.) what's the easiest way to clean out the pilot circuit?

after the gas is drained, I need to pull the float bowl off to clean the pilot jet; can I just unhook the fuel line, then just twist the carb enough to get the screws off and the bowl off to access the pilot jet?

I perused the internet and I found out that the air/fuel mixture can be made leaner by moving the clip on the needle up. I currently have it set on the third notch as it as sent to me by Kientech.

What do you think of moving the clip to the highest (leanest) slot? Do you think it will have enough of an effect?

Thanks.
