Here are the circumstances as I see them:
- The ride home is a straight 70 mph shot down that highway 94 I've mentioned several times once I get out of town (4 miles of intown 55 mph riding).
- In town riding consists of buildings, homes, businesses, and other cars while the highway is open with no obstructions (especially after the 17 mile marker) but with one long steep hill and cutouts from smaller hills the highway travels through. It's two lane pretty much the entire way after getting out of town
- Only times I lose power is if I'm facing a strong SE to NE wind (today's wind was SSE at 15mph gusting to 22mph but felt more like it was coming from the east).
- It acts like a vacuum leak but I can reduce speed, downshift, throw petcock over to prime and still have the problem. Vacuum line, intake boots, and airbox side boots all look good - read no cracks that I can see.
- When I do reduce speed I can swap back over to "on" and the bike runs but I'm at a slower speed and will experience surges that sometimes helps to clear out the issue and sometimes not.
- Temperatures outside today were mid-90s which has been about the same during the other episodes.
- Only happens in the afternoon, no other time so far
- I wasn't out of gas (odometer was at 70 miles and I normally swap to reserve around 100 miles)
- Does not do this every day but almost always if I'm running into a wind coming from the east (I drive east in the afternoons, west in the morning).
- I think my air filter needs changing but I've only put 4000 miles on it so I'm not positive if it's time
- Fuel flows perfectly every other time and I don't have a problem if the wind flows from the west on the way home (sometimes does) or directly from the south or north as best I can tell
- I sealed the air box this winter and those screws are tight.
Thanks
