Fuel shut off

[Dukester]

I have been reading my owners manual and it say not to trailler with gas above the carbs so as not to pump fuel into the engine. In the past I had fuel shut off valves. Has anyone had this type problem? After a brief look it seems there are 2 fuel supply lines comming out of the tank. Is that correct? If so 2 fuel shut off valves are required, right! Help please!

valves

yes you would need two valves

Sketr2 Your dealer should have the shutoffs there are two places that I've seen them installed. 1. Right at the fuel pumps 2. Attached to the Steering column frame right where they come out of the tank.

Good Luck

Sketr2, there was a big discussion on this topic last fall after others saw that part of the manual. Some people actually installed their own shut-off valve and posted the pictures, while others said it really wasn't an issue. I got so concerned about this that I called my dealer, but they were not aware of any issues. I then called Yamaha HQ in California and again they said there should be no issues. I then called a friend that is the lead engine for independent engine testing company. We talked about it, and while it is possible that some left over fuel in the tank could cause problems while trailering, it was unlikely.

I trailered all winter driving more than 150 miles each time with fuel in the RX-1, and no problems.

I have read many posts on this subject and was looking at the Yamaha site this morning and found this,

I guess they think there is a problem. I am ordering my valves today.

All the yamaha manuals say that. It just means the possibility is there. I trailer every weekend and have never had a problem and neither has any of the other 3 yammi guys I ride with. If it happens, maybe I'll buy one, but probably not. One guy put one on his polaris and the only problem he has is pulling it over 20 times before he remembers to turn it back on. :roll:

I installed em but only because my polaris would never start after trailering if I did'nt shut the gas off POS :evil: . Guess I would rather be safe than sorry hell it's only $20 so if it gives you peace of mind go for it. Does make it easy to empty the carbs in the spring shutoff and run it dry

If this is what Yamaha wanted why did they not put a shut off on from the factory.
why should we have to finish the job?? :?:

For the same reason we did'nt get the rebuildable gas rear shock or a decent track "to save a buck or two"

 

[ger]

but as bad as the shocks are they are there and so work somewhat ( not looking for an arguement here ) but if they say we should not trailer without shutoffs then they should put them on, they could put shtty ones on so we would have to change them later but at least put it on

I agree it was a shitty thing for them to do they claim the vibration if at the right frequency can affect the diaphrams in the fuel pumps Like I said I just put them on because of the bad experiences I had with my other sleds. In fact my XCR was so bad I had to shut it off everytime we went into a bar or it would just flood and be a real PITA to start. To each his own man thats the beauty of this forum we can all speak freely.

2 things.

1. Don't buy the yamaha shut off valves. You can go to any motorcycle and/or snowmobile shop and get them half that price.

2. I agree with Convert. I travel over 100 miles one way on rough road and never had a problem, but put the shut off valves on anyway 2nd to the ease of emptying the carbs at the end of the season.

shut off,s

there are vacum shut off,s built in to the fuel pumps all ready that shut off the fuel supply when the sled is shut dowen. so let,s not reinvent the wheel here guy,s 8)

i trailered 10 times last season, average 350 miles per trip, full tank, no problems

Twice last year I trailered to Ontario-9 hours each way and had no problems with either my RX1 or my wifes vmax 500. Never had any problems with earlier Yamahas either.
