22 cent mod and or Doo Hickey For 2009

So, i have checked here and KLR world and saw how to do the 22 cent mod and the doo hickey mod. My question is, is it necessary on the 2009? I just did the mod on the gas cap (removing the orange check valves) and I noticed an enormous difference right away with regard to surging at constant throttle. Is the doo hickey that jacked up on the 09 that it needs to be replaced? I have 4000 miles on my 09, and it seems to be running great right now. I'm a big fan of if it ain't broke don't fix it, but i love this bike and I want to get the most out of it.

There's not much danger of the doohickey breaking so no worries there. BUT the spring is too long and will not adjust the tension on the balancer chain so if ya got change the spring you might as well change the doo as well.

You're eventually going to have to do the doo, imo. Put the order in.

The KLR 650 has a notoriously lean set carburetor from the factory. Aside from performance [or lack of] issues, a lean set carburetor will create a hot running engine, which I believe will shorten the lifespan of the engine. A simple readjustment of the air / fuel mixture screw will solve this. Drilling the slide and shimming the needle will create a much better throttle response, and probably one of the more significant performance modifications an owner can make short of going into the engine. If I were allowed only one modification, this would be it.

The balancer idler lever, AKA the doohickey. There are shops and mechanics using the same doohickey you have on your bike on pre-'08 models to replace the weaker, less reliable doohickey they came with. Spring tension seems to be an issue on the Gen II doohickeys. For under 15 bucks, you can upgrade the spring and have some peace of mind. This would be a good reason to hit a tech day session some time. The tools and know how would be present at one of these tech sessions.

Thanks folks. That's just what I was looking for. I didn't realize the lean setting from the factory made the engine run hotter , I just thought it degraded performance a little. I also didn't realize that the spring tension was the issue on the gen II bikes, and not so much the "doo hickey".

So I just completed the 0.22 mod. (0.16 in my case) on my 2009. It was pretty easy using instructions from KLRWORLD. Getting that diaphragm to reseat was a bit of a bi%$&, but it turns out mink oil is good for something other than oiling a baseball mitt. I took it for a quixk spin around the block and noticed immediate improvement in throttle response. Can't wait to get it out for a ride to see if it improved the ride-ability wrt surging and the like.

One thing to note, is that I had to remove the big fuse box on the left side where the battery and starter connect to get to the bottom of the carb to adjust the fuel mixture. Word of caution to make sure the loose battery connection doesn't touch the starter wire... If unavoidable, take the bike out of gear. I had a rodeo-ish ride through my garage hanging off the side of the KLR! i think I held on for 8 seconds before I realized what was happening and pulled the wires apart. Whoops! Thank goodness for a cold beer afterward.

Beer is good. And I agree with vatrader. If you got the money, buy the doo. If you don't, put in a shorter spring. I have an EM doo cause money was more available then. Today, I would put in a better spring and ride. My.02
