4 posts in this topic

I have a 1993 honda 300 trx and i used to ride it a basiclly sea level, now i live in the mountains and am riding at 1500-2500 feet above sea level. Im wondering if there is any carb adjustment i should do.

Thanks

You should be ok still at 1500 feet, but you may want to drop the main jet one size if you go up past that. You may also raise your needle clip one notch and adjust the air screw. You may or may not want to drop the pilot one size too, if it runs a little sluggish on the bottom end, then drop the pilot too.

For every 1000 ft you go up in elevation, you want to drop one size main jet. I agree with Dirtdemon that you will be ok.
