    Ive decided to do the 22 cent mod and was wondering if I should do the L mod at the same time?

    instead of cutting out the L, I drilled four 1" holes in the box. much cleaner operation & easier to fix if you decide to go back. dumped the snorkle too. does it help? meh... mebby. I have a Gen I so ymmv

    "mebby..."?

    I have never seen any documented before and after, specific, measured information that confirms the L mod or the snorkle removal mods work. Lots of anecdotal and tribal banter. Makes more carb related noise - same as noisy exhausts. A waste of money on a KLR - unless noise and looks are what you want.

    As I have commented before in other threads, I tried the KLX needle, drilling the slide, other jets etc and eventually about 40K miles ago, happily reverted back to stock.

    I did the 22 cent mod and found it helped to stop some of the popping on deceleration. If you are looking for more power, not so much.

    it makes the throttle response quicker... more hp? not so much... mebby, but only a fraction if any... pretty negligible

    anyway... why not... klr's struggle for any gains

    Advance the exhaust cam 1 tooth. Better result and cheaper than 22 cents

    i would say do one thing at a time. 22 cent first see what happens. May be pull the snorkel next than the l mod, though i like beezers idea better.
    Doing too much at one time gets confusing especially if something goes wrong or you end up not likeing what you did. Also 22 cent richens engine in first part of the throttle opening up air box leans out every where. My basis recomendation based on my, limited knowledge and experience with two bikes klr and ktm is to check out james dean jetting before you do any cutting. There may be nothing wrong with other ways but jd has worked for me.

    For me, I don't like the .22 mod because I don't like the needle taper. I use/used the KLX needle, which has a much better taper design and it works perfectly well. The .22 mod is a cheap band aid for a needle designed to meet clean air standards and not performance. :deal

    and if you start fiddling around with jets be aware that Kehin, Mikuni, and Dynojet all have a different size hole for the same jet number... do not mix.. it will drive you insane. how do I know this?

    Took the plunge today and gave my bike the storied 22 cent mod.
    When finished I only managed to take a short loop or two around my apt. complex as a test. So far I would have to say I am glad I did it, lean popping on deceleration seems to be gone and that alone is worth the trouble.:D

    I never did expect any HP gains so if the bike hasnt gained any power I am OK with that. Smoother roll on power and less hesitation when cold or at very low RPMs will also please me..and the bike.
