Going to trailer the RX1 to Wis. this weekend. The manual says I should put valves on the fuel lines so the cylinders don't fill up with fuel.

Do I really need to do this??

I played it safe and did. Many have reported no issues, but I have read of a couple guys hydro locking their engines. It's cheap and easy insurance, do it.
 
I trailer mine at least once a year to Ontario and back, total of about 1200 miles each trip. I have never had a problem. I don't keep the tank full though, anywhere from 1/4 to 3/4 full.
 
I did it too! After one of our members went to start his engine after trailering and the engine went POW! :( It's cheap insurance, you can also shut the valves and run the engine till the carbs run out of fuel for maintenance purposes :D
 
I've trailered my 04 RX1 hundreds of miles with a full tank of fuel and no problems. The gas station is less than a kilometer from my home, so I fill it so I don't need to search for fuel when I reach my destination. Just start and go. This does NOT mean that at some point I may have a problem, but so far so good. :wink:
 
No

I must trailer my RX-1 for all my riding and have never had a problem after 5000 miles and i always keep my tank full. Not a single problem on smooth or bumpy roads.
 
Trailering RX-1... Do I need fuel valve shut off's

Obviously Yammaha do not consider it necessary but the consequences of a stuck or leaking float are serious and it is cheap insurance.

The benifit alone to be able to shut off fuel and run carbs dry for service or storage is worth it.

I do not believe the engine failure reported months ago due to hydraulic loading the crank case was warrantied.
 
I ran into where I trailered, did not have them, had a full tank of gas and yes, carbed em right up due to the fuel dumping in. I would recommend it, or trailer it with a smaller amount of gas in there.

I rarely trailer mine but for the cost of a couple shutoffs and a half hour of time I put them on/ cheap insurance/ and even if you got Yamaha to cover it do you want to ruin that weekend or vacation and have the sled tied up for a couple of weeks while the dealer waits for parts etc./ also sometimes when you trailer there's no gas at the starting point which means you've got to carry gas and fuel before riding or start out with less than half a tank and hope you can find fuel in a few miles/ put'em on and just enjoy the ride/ all the possible grief and aggravation are gone/ later
 
The manual says not to trailer with more than half of a tank of gas. I put them in because where I drop there is not always gas. Like the previous post say, it is cheap insurance. Who wants to start there ride off with a problem. Great advice.
 
cheap insurance

when we ride, we fill as soon as we are done riding. I think leaving a tank anything but full is the best way to get watyer in the tank, so dont leave room for it. Shut offs are very cheap and incredibly easy to do, and I also added a couple clear inline filters. I had a polaris hydrolock, because I didnt shut the fuel off, cost me an engine.
