Hello!

Im from Portugal and i have a XT 600e 3TB. iv read here on the hub someone say something like this:

But, the inlet openings of the the airboxes are notoriously small
Ill also drill the airbox(get rid of the nozzle completly?)

sorry, what is this about?

under the seat is a rubber inlet snorkel that you dont need, i think it might be there in case you think your bike is a submarine.
drilling out the airbox is something supermoto riders do to improve the airbox on tuned up competition bikes, but i cant think how it would improve a low tuned bike like the XT. it also lets all sort of rubbish into the airbox. looks trick though i guess.

ou wont gain anything from that, its jettet after thtat, and even with a rejettet carburetter, you'll have a stock exhaustsystem that wont be able to let it out.

And you get more junk clocked up in the airfilter.

Hey man
This is what worked for me with my 86 XT 600e.
I had over-rich conditions, plug told me that. i peeled the carb, float was correct, jets in mint shape all nicen clean. I started looking at the airbox design and herein lies the problem... its junk. The design is very restrictive. I removed the airbox used a keyhole saw bit and drilled 2- 3/4 in holes in the side(the side panel covers them). cleaned and primed the air filter. Then I removed the spark arrester fron the tail pipe, cleaned it and trimmed the four fins down with a small grinder so it still has support. Then cut the outside screen off and removed the crimped end so it was almost freeflow. Made it sound throatier and deeper but man did it ever increase the mid range torgue. Those two mods breathed new life into the bike but please remember what worked for me may not necessarily work for you. Check out my sprocket woes in a earlier post. If you want pics let me know.
