Re: [TR] Travel and tuning question

Sounds like a great trip - I didnâ??t make the last tour with my other FOG 
buddies but when they went through the Rockies the #1 issue at altitude was the 
mechanical fuel pump cavitating due to ethanol gas we think.  A couple guys on 
the trip hooked up temporary electric pumps and had no issue - no carb 
adjustments were made for any of them.
