Has anyone tried a split fire in a big single 400/450/650? I am wondering if it would improve anything on the DR at higher altitude...

Besides re-jetting for high altitude any recommendations? Air filters...octaine booster...

+1 splitfires are mostly gimmicky.

Up your amperage. Find a coil/HEI unit that goes to 11.:headbang:

open up the air box (3x3 mod)
otherwise if you want more power out of a drz it takes $
Octane booster is not even a consideration, search octane on here and learn the facts about it.
Go to Thumper Talk in the DRZ forum if you want some in depth answers. Look for Eddie Sisneros (sp) he knows what he is talking about, take other advice with a bit of caution
