You can test ride it on the prime setting without any problems but remember to turn the tap back to 'ON' when you stop riding. Also you will not have any reserve fuel so keep the tank filled.

If your test ride(s) using 'prime' are OK then I would not mess with the jetting but check all the parts of the fuel shut-off valve and the vacuum connection.

You could also replace the fuel valve with an older model that has the 'OFF' 'ON' and 'RESERVE' settings and no connection to the vacuum fitting. Be sure to plug the vacuum connection if you make the change to this manual fuel control valve but now you would have to remember to shut the fuel off after each ride all the time.


Good luck and let us know what you find out.

We pulled it apart and took a look. My hubby had suspected the same thing... that or that I ran out of gas. What we came to the conclusion of is that the vaccum is fine. It was weird when we were trying to drain the tank becuase the gas wasn't draining when it was on "on". So, we pulled the whole thing out of the tank and discovered the "on" setting pulls gas from so far up the tank that after a gallon or so has been used (in the 2.4 gal tank), the "on" setting can't pull fuel anymore... it's too high. "Prime" and "reserve" both pull from a lower fitting. So, I'm going to try running the bike in "prime" or "reserve" on my way to work tomorrow... I had almost a gallon left in the tank when we drained it.
So, I figure I will try again tomorrow, fill up, and see if it still does that with a full tank in "on". If it does... we've got some more digging to do. If not, I think the problem is solved... I ran out of gas without being out of gas.
yay! Love my little jelly bean tank!

I pulled over, wouldn't start, wouldn't start, wouldn't start, flipped the gas to "prime" and started right up and made it the rest of the way home.
And yes, I did have gas in the tank.
If there's a fuel filter in the gas line remove it. If the gas line is too long and droops too much from the tank to the carb, shorten/replace it.

My Sherpa did the same thing when I tried to put in an inline fuel filter. I'm running a transparent piece of straight hose now, so I can see when/if there's no fuel in the line.

It's probably also worth checking the petcock, to see if the vacuum line still holds vacuum. If you do a little searching, you'll find information on how to replace it with a manual petcock from an XT350. There is a Yahoo Group called "1999-2003 Super Sherpa" that has a lot of information in it.

Your problem is almost definitely not jetting, but if you do want to rejet, put a message in to DrJeckle in the Yahoo group. He can set you up with the jets and instructions.

Might try cutting the pipe that is 'too high'

You could try cutting the pipe that is 'too high'. The more you cut off that pipe the less reserve you will have but most small bikes only have one quart or two reserve so one gallon seems excessive.

As long as you remember to pull into the very next gas station once you switch to reserve you should be fine. or get hubby to carry spare gas for you

I really should do that to my sherpa as well. The reserve on my sherpa sounds like it's a bit smaller, but it's still 1/3 of the tank - theoretically giving me 70km+ range in reserve, but running the bike a loooong way on reserve doesn't seem like a good idea, so a lot of the fuel capacity doesn't get used.

Wow! I'm speechless, Hammock dweller. I'm retired American military, so the post was very moving. Beautiful shots, btw.

A couple of questions, if you don't mind.

1. What model of Givi is your top box.
2. What's the make and model of your tent. That thing looks awesome!

Very nice! Are those E21's on the side? Tell us more about the Yahama. I don't think I've heard of that model.

Klay;

As we had already exchanged via PM's the carb had high altitude jetting. Such would not cut it here in Michigan.


Just thought I would also mention here.

This is the 5th? time it's done this to me this week. Each time was a bit different, but all the same... humming along and no signs of trouble... then it just dies.
No noise, no lurching, no sputtering... nada.
I'm convinced it's either the jetting and it's starving itself or the carbs are completely shi-lacked and need to be cleaned. I haven't checked the carbs yet... have to sweet talk the hubby.
Suggestions?
Join the sherpa yahoo group and there is a guy on there that sells a little jet kit and very detailed instructions on setup. I think it involves drilling the fuel screw (brass cap) and installing a larger main jet....possibly a new needle or a spacer. I did this to mine several years ago. The kit is cheap...$15 IIRC and is a great improvement. You can just start it and ride after dialing it in....no more 10 minute warmups.

You might check for a pinched fuel line or clogged inline fuel filter. Sounds like fuel starvation under load.

Re-jetting these small bikes really helps also. From the factory they are all too lean in order to meet EPA standards.

Good luck tracking the problem.

tremor38, to answer your questions...

The Givi is an E52 maxia. It looks huge on the little XT but when you have to cram all of your camping gear on the bike there is no substitute for cubic inches, as the saying goes. It fits well onto my homemade rear rack and it handled the weight no problem. If I lean right back I can use it as a backrest. No room for a pillion on there!

The tent is a Hillerberg Nallo GT 2. This is a lightweight, fullsize 2 man tent with a large vestibule on the end. I can get all of my panniers inside there and still have enough room to sit and even cook if it's raining. This means that I don't have to keep going in the sleeping area when the bugs are out. It packs down pretty small, I fit it inside my E36 side pannier when I'm on my Tiger and it only weighs 2 1/2 Kg, 5 1/2 lbs. The only downside is they cost 400!!

Haha! Yeah, I figured it would look pretty big on the XT. I use a motofizz most of the time, but I find myself craving the simplicity of the Givi, no matter how big it looks. I have a KLX250 D-tracker, so the E52 wouldn't look any smaller on my bike . Not having to worry about a rain cover and having the one key lock/release is definitely a plus though.

I dug through the entire thread a bit earlier, found the brand of your tent and went to the website. Looks like a quality product and I love the design.

Talking Random factoid...

I just felt like I had to brag about this all of a sudden. This looks like a good place to do that...My TW200 with a 55 tooth rear sprocket has ample hill-climbing torque at an indicated 2 mph without using the clutch. AHAHAHAHA. I just really like my TW and my snail tractor gearing...felt the need to write about it.
