I have 930 miles on my F7 and I tipped it up on the clutch side tonight-I was trying to find out why I had a jerking feeling on engagement (it was a chunk missing out of my belt). Anyhow-I starved the smart valves and sure enough they collapsed and the sled stalled. I tried to get the recall done last week but the dealer is currently out of smart valves-he has more coming. I pulled the rear valve and freed the membrane up (like I learned here on the site-Thanks guys! ) and the sled started right up. My question is this-I couldn't get the front valve out of the tank, not enough fuel line-should I assume it is collapsed too? I plan on riding tomorrow-should I be worried about anything? I tried to buy updated smart valves at the local dealer (not where I got the sled) and they told me Cat is sending them only enough to do the sleds that they sold. I'm thinking that as long as I don't run the tank too low I should be OK. Does anyone have any thoughts on this? I'd appreciate your input.
