Wink Breathing advice

Hi there, first post, have ridden long time but new to KLR'ing. Just got an '11 that was bought new a year ago. Am looking for advice on some intake and exhaust mods to free up some power and 'sound' without breaking the bank. Have already ordered K & N, looking at slip-ons and jet / needle kits, any ideas? Nice to be riding in January, sorry rest of Canada! cheers

You should start here, where there is a large collection of information you might find useful.

Others will chime in with their experiences, but I'll start. The K&N is generally held in low regard in the KLR community, the UNI being preferred. Even the stock is preferred over the K&N.

The only slip on I ever tried was the SuperTrapp. I found it to be loud, way too loud, when properly tuned. Stay away from it, even though it's cheap and tempting.

Lots of folks like the Lexx.

x3 on the Uni's.

I like to have two of them on hand. One that's clean and ready to install so when I pull the dirty one to clean it I don't have to wait for it to dry.

My advice is spend a bit more and get Twin-Air air filters especially if you use the No-Toil products. The Uni filter's glue gets soft with the No-Toil stuff and the filter will split at the seams eventually.

UNI, 4 hole drilled into the top of the air box 1" in dia. no larger, Remove the snorkle, KLX needle kit, if money is tight, my way of doing the low buck exhaust mod, research it here or elsewhere, if you can spring for a LEXX can they work very well.!

You will find this to be the best way, in the long run, we all mostly have. We all usually go the few cheaper routes before learning this, but money will dictate. Why spend it one cheaper routes first?

We all have been in your shoes.....the majority will say this is the best way....that is until you spend serious money on big bores, cam, head work and carb swaps...........get some boots that can grip the slippery slope you are about to step onto......it's a fun ride...enjoy!


Hpe this helps.....

Thumbs up

Thanks all, have already ordered Doo kit and K & N, won't be doing a lot of 'dusty' riding [ am on the 'wet' coast after all ] so hopefully filter works out, was it harder to clean or something else not liked about it? Will prob. do klx needle kit , air box mods and Lexx. Also wondered 'bout best shock settings for 225 lb rider? Cheers

One factual report on the K&N was that, on a bench flow test, it flowed less than the stock filter. Opinions from users were that it did not filter well, allowing dust to pass and that it clogged quickly.

I spoke with a gentleman earlier this week who had removed his K&N and replaced it with a Uni. His immediate reason was that the K&N filter was poorly constructed, the cap having become loose, and that it did not seal properly to the air box.

Interestingly, this doesn't seem to be one of those issue where there is a camp of K&N lovers and a camp of Uni lovers. It's a general consensus that KLR riders don't like K&N.

My advice would be to use it, paying attention to its fit, cleanliness and general state of repair for its useful life, then either revert to the stock filter or go with a Uni.
