Is that yellow thing screwed into the airbox a prefilter you made for your open airbox. I just used a nitro r/c car engine air cleaner for my breather.

Same here. I bought my mag plug at Auto Zone. It went in a little harder than it should and when I removed it at the next oil change the threads were bunged up. I put the stocker back in but need to get a quality mag plug for the next oil change. My 07, 4000 mile DR needs to have the NSU checked this winter, valves too. She sure runs quiet and smooth right now.

Carb probs

Hi guys, I'm trying to get a handle on this so I can get at it today. Hopefully everyone is out riding istead of answering this. Iced up here so maintenance time. I'm having a stutter in the first third throttle range. I found this pick and have been reading as much as possible, but can't wrap my head around it for some reason. I have a bone stock 09 DR, only thing I've changed is the air filter. To a K&N and took out the snorkel. So I found this pic and have a few questions,

Does the carb have to come off to get at this fuel mixture screw? And what should it be set at (turns) once I get in to it. Has anyone had the same issue and found adjusting this to be the answer? Thanks

Part of the reason you're having trouble figuring it out is that this diagram shows the idle mixture screw adjusting airflow, whereas the idle mixture screw on your carb adjusts fuel flow by being inside the pilot ("slow") jet. On the stock carb the fuel screw is covered by a removable plug. Once the plug is popped out, you can adjust the mixture (screw in to lean the mixture, out to richen).

It's a prefilter made for snowmobiles, used to change jetting as the weather changed, by controlling airflow. They came in a 2 or 3 pack from Thunder Products.

Do you have a pic or link of the RC filter?

Excellent! I know where the pins are in the shifter cam-driven gear, but is there another name for the "cam knock pin"? I'm not sure what/where that is. Thanks loads for taking the time to help me figure this out. I want to get back on the road!

my guess is too lean. try taping the hole in your airbox up & give it another ride. when i re-jetted my bike back to stock for mileage for the LAB2V last week, i had to close up the airbox to richen it up.

New to me

I just picked up my second DR the other day, its an 05 with 5000 miles on it, first one was an 01 and got rid of it at 25000 miles. the 05 has a whine when in third gear but other than that runs like a champ. The 01 had a procycle high perf kit in it and ran real strong, but it had no whine at all from the tranny. I guess my question would be how long can i let this whine go without looking into it. is there some kind of oil that is better for the tranny? i always run Mobil 1 4T in every bike of mine. I read about the neutral switch screws and will probably do that at some point this winter, any tips on making it last would be great.

I'm sure the magnetic sump plug I got through the local Suzuki Dealer was from another suzuki bike. The bloke behind the counter seemed suprised it didn't have one as standard.
