[TR] Travel and tuning question

[Randy and Valerie DeRuiter]

Dave

Sounds like a great trip - I didn’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.

Our first destination is going to be Colorado Springs, Co. to drive up Pikes Peak (altitude approximately 14,115’). Then north to Mt. Rushmore (altitude approximately 5,700’), then north to drive through Yellowstone national park (altitude approximately 9,200’). That’s going to be quite a swing in altitude and I am wondering if I will have to occasionally tune the SU HS-6 carbs? Has anyone on the list done a similar drive? If so, how did your Triumph run and what did you have to adjust?
