scared to touch the carb

Guys, I have a 2009 that I want to do the 22 cent mod to. I've looked and found articles how to do it, but none that are step by step for a guy who hasn't messed with a carb before. I really don't want to screw it up. Is there a step by step instruction with pictures for dummies that I have missed? Also, I've got a Lexx pipe on order and it came with a K&N filter. I also ordered those little foam filters from Uni to put in the airbox. Thanks

Run the stock filter, pull the snorkle from the left side of the seat. You can do the .22 mod with the carb still on the bike. Just loosen the clamps in the front of the carb and behind it and rotate the top toward you so you have access. If you've never done it, it will be intimidating. Watch some vids on utube. The bottom plug can be drilled out while still on the bike as well, you just have to rotate the bottom out.

There's probably a video on the 22-cent mod up on the 'Net; Google it!

Other KLR websites may have detailed procedures . . . hey, what about THIS ONE?

Ain't the 22-cent mod in the 'Popular Mods" thread?

(Same for both generations.)

Hey guys would you recommend this mod for a new bike? ( under warranty)..? Does it really open it up enough to tell? And what exactly does removing the snorkel do?

Some 22-cent mod pictures:

IMHO, the 22-cent mod's worth doing; adjusting the fuel screw fuel-enriches the idle circuit, shimming the needle fuel-enriches mid-range operation, and drilling the slide improves throttle response.

As to removing the snorkle, ain't been there--imagine the object's creating lower-restriction intake air path . . .

Attention MODERATORS:

Ain't the 22-cent mod in the"How To's & Tech Guides" Forum?

Should be, IMHO; couldn't find it.

Common mods and issues thread here.

To the OP - disconnect the choke cable from the carb before you turn it. The plastic fitting will break if you don't.

The OP has a Generation 2 KLR; of no consequence, regarding the 22-cent mod, although the dating in the forum title may have caused him to overlook the information.

IMHO the K/N filter doesn't flow as good as the stock filter and it is agreed that the Uni filter is the best filter to have in your KLR. The K/N is worse than the stock one so unfortuneately I would sell it to someone who doesn't know this...sorry.
Yes the 22 cent mod is worth doing, but while in there drill the slider to 7/64" to allow the slider to move quicker during it's range. IMHO, I would spend the money and buy a KLX needle kit from Eagle Mike and do it right first time around. The needle is adjustable and has a much better taper to it. The kit also comes with new stainless steel bolts for the top and bottom of the carb. I would also drill out the pilot jet screw and set it to 2 turns out from seated as a starting point for the best setting for your bike.
Before you undo the intake and airbox boot clamps, loosen the choke plastic clamp that the choke cable attaches to the carb with, it takes a 12mm wrench IIRC and is a pain in the arse to undo. You need to remove this from the carb BEFORE rotating the carb or you WILL break it's plastic locking fingers that holds the cable firmly into the carb. It is very easy to break these clamp fingers. Some people just pull the cable out and let it hang but it is still easy to break the clamp fingers. Once broken the choke won't seat against the carb firmly.
The rest of the how to should show you the rest.

The 'Common Mods and Issues' thread covers Engine, Chassis/Suspension, Frame, and Electrical.

Many of the items are applicable to both generations. For that reason, there is an exact copy of the thread in both the '2008 +' and the '1987 - 2007' sub-forums.

The 22 cent mod, the KLX needle, the L-Mod, and the broken choke nut are all covered under 'Engine'. I believe the Snorkel is covered in the discussion of the needle mods and perhaps the L-Mod.
