Fuel usage

[-chris-]

Hi all, newb question here. I'm trying to find out how long you get out of a tank of fuel on a superjet and an SX-R both stock just doing normal riding? Thanks. Awesome forum you guys have here aswell!

2 1/2 to 3 hours of non stop shredding on my SJ.

 

[BombThreat]

My SXR manual says something like 36minutes @ full throttle.

 

[Mouthfulloflake]

really?

my 650 powered superjets with single carbs never lasted that long!

just cruising around, maybe an hour?

wave jumping, and things that require throttle "pumping" less than 45 minutes per tank.

those are approximate for the single carb 61x I can last year.

2 1/2 to 3 hours of non stop shredding on my SJ.

I know my crew here only gets about 1 to 1.5 hr per tank if we are lucky, and that is just cruising up river, wave jumping and very little WOT. Of course we all ride 760 - 800+ dual carb big bores or strokers. I also remember when we had a SXR in our group, it sucked fuel faster than our SJs.

I get about a 1-1/4 hours at the lake and about 1-1/2 hours in the surf on a full tank.

so i'm looking at 1 hour for the SXR and 1.5 hours for the superjet?

i got an hour and half to two on a limited sj set up - ocean wave jumping

I wouldn't say that. Stock 05 SXR and 05 SJ in the surf were very close. Mine went to reserve and by the time we were in to the dock the SJ was about 10 min away from reserve. Modded, now that's a different story. The SJ lasts about 20 min longer.

my superjet last about an hour or so of riding in lake mi, but I have to go threw the channel, it take about 15min each way, so I would say I could get 1.5 to 2 hrs. My sxi pro was better on gas than the yam. hope that helps.

I have noticed that before, as well - the only explanation I came up with is this: because it's underpowered, you're WFO all the time.
And if you're moderately heavy, there's quite a load on it, too.

 

[Mouthfulloflake]

IM not heavy!

hahaha

180lbs or so.

it seems hard to fathom that a 650 can use more fuel than a 701..

but yeah, WTFO most of the time is what im used to, even with the 61x last year.

Ok, so basically the superjet gets about 15 mins more per tank then the SX-R?

Ain't no way. Watch closer next time you ride.

 

[keefer]

Maybe they are really short hours :trink26::439:

 

[MADMAT]

I know for a fact that my mildly modded SJ (a little lighter too) will run for 2.5 hours filled to the max (internal fuel fill). I am rarely WOT.

I'll try for 3 hours this summer and see what happens.

 

[MADMAT]

Weird thing too. All the Cleveland crew has different set ups and none of us get the same "mileage".

In that case, non-stop shredding and "rarely WOT" don't go hand in hand in most folks' minds.

 

[keefer]

I could see getting 2+ hours if I did no cruising and shred / jumping only.

My '92 Seadoo XP runs for 2 hours off-and-on (mostly on) riding for 5 gallons.

I've been getting close to 2 hours for 4 gallons in the '89 js550
