XS Southeast 2015 discussion

Mileage up to 33.5MPG - Get me gas lamp at 110.

Last MPG check on an SF was 36 with 2 up and 40 solo. Mostly straight and some small twisties. I will not get my best mileage if on an all day mountain twisty ride, but it will not be less than 34-35

XS Folks,
I wasn't going to fess up to this but...... I knew the specs, was SURE I did it all correctly. BUT, I pulled the carbs last night to take ONE MORE LOOK before XSSE so I have plenty of time for local testing.

The floats were off sooooooo far I can't believe it ran so well. Only carb #1 was correct. #3 & #4 were so far off it looked like a mile (AT LEAST 3mm high). #2 was closer but still crap. I re-set them to spec and re-checked it multiple times.

I drove today two-Up driving and I was absolutely flogging it at times. Got 'er up to 85 once or twice (short burst) and drove higher RPM's at 45mph for like 30+ miles. Give me gas lamp started flickering at 105miles.

Gas mileage is now at 33.5. If I hadn't been beating the snot out of it I probably would have gained a mile or two.

Thanks..... YOU WERE RIGHT TO TELL ME TO CHECK 'EM.

Respectfully,
KURT

P.S. The first time I pulled the carbs I felt it was like I went 10 rounds with Mike Tyson. After I got the tank out of the way it took me like 5 minutes to get 'em out and about the same to get 'em back in place once cleaned and adjusted.

Just bumping this so that it will show up again on the LAST PAGE of this thread, I had merged it with this thread, but because it was a few days old, it got put/merged by creation/post date into the thread and on the previous page!

[DeanR]

Hope to maybe make a short howdy visit to Motoman & Motowoman on Sunday 13th if they are up for visitors.

That sounds like a fine idea Jeff!

... One more repair done as we get closer to XSSE.

Kurt,

Hope you can make it. As previously posted, some of us Atlanta riders will be staying overnight Thursday Sept 24 at Days Inn, Cornelia (just off I-985 / US23 on Level Grove Road). E-Z to find with convenient fuel and a Waffle House just across the street. Don (from Tallahassee) and I will be meeting Brent & Marty up there on Friday around 9:30AM. Along with any other Florida riders that are coming up for the Rally. btw: Days is like $60 with tax.

But first I'm riding out to Utah with Stewart. Will break off at Zion National Park / Hurricane UT on 16th and get to Atlanta on maybe 22nd. With SE Rally that will make a 5,000 mile September. Not bad. Hope to maybe make a short howdy visit to Motoman & Motowoman on Sunday 13th if they are up for visitors. I'll be 2 or 3 days ahead of Stewart coming back so he will not make the SE Rally.

So we hope you get your XS working to your satisfaction so you can bring it to the SE Rally. Ride up Thurs pm to Cornelia and beat the nasty Friday Atlanta traffic.

See ya,
Jeff

Kurt's a DUMB BUTT!

OOOPS.... Kurt's a DUMB BUTT! Took a MUCH closer look! I was putting it on wrong. Disregard it IS the correct part. The THING the PO has installed was a lot different. Thanks again Marty.... One more repair done as we get closer to XSSE.

2M0-24641-00-00 is the OEM one. It will cost twice as much, but will last at least 20 years instead of two.

Received from Partzilla and part number on package is correct. Won't fit my cap. Not even close. Does a SH have a different cap? It's listed for an SH but not for an SG?

I like your style! I hope you'll be able to come down and join the party.

I am trying,changed a dr's appointment and as long as she doesn't send me to the hospital again I am hoping to make it by car.not safe right now for me on a bike or those around me. Life throws a curve ball now and then.
Don't let the good times pass you by grab all you can.

The Iron Horse is down to one bed for our weekend. Get it, or pack your tent and sleeping bag! This is proving to be a popular rally.

Idle mix screws only affect the idle circuit. Once the throttle gets twisted the butterflies open and it's all about fuel level, jet sizes, needle position and air flow/restriction. This is where pods and non stock pipes get people in trouble. You've got to make sure those carbs are dialled in.

Special

XSFolks,
I did a little testing the last couple days. I filled to the tippy-top, fortunately no leaking as I do not have Partzilla cap seal yet. Low fuel started flickering at 97 miles. Filled up at 107. Based upon the amount of fuel taken vs. mileage I'm getting only 30.5 mpg. This is all one-up driving and pretty much keeping to the speed limits.

My plugs do look pretty good with only the very slightest hint of soot. BUT, as stated I was seeing a good bit of soot in the tail pipes. I made an adjustment to the carbs (in 1/2 turn leaner on each) before the test. Doesn't seem to have had any effect. I may go a little further?
I'm at 1-3/4 turns out from fully seated at this time on all carbs. Sync is perfect across the board. Floats are within 1mm of each other and at proper height.

Hi Kurt,

Last MPG check on an SF was 36 with 2 up and 40 solo. Mostly straight and some small twisties. I will not get my best mileage if on an all day mountain twisty ride, but it will not be less than 34-35. Plugs are quite lean appearing. I frequently use non- ethanol 90 octane fuel, but not always. Upgrades include Dyna coils, Iridium plugs, and K&N air filter.

All carb parts are stock and Mikuni brand. Floats are adjusted to the lowest (in the bowl) setting by Yamaha manual. Lowest setting insures a leaner burn, no fuel leaks into carb throat when static, and better fuel consumption. Needle jet clips are in the standard location.

From a static test of 3 different float settings (all within Yamaha range), I found that over a 24-48 hour period on each test, that there would be some weeping of fuel into the carb throats except for the lowest setting. Fuel was left on the entire time. This was done in the winter, so I would guess that there would be more weeping at higher temps. I'm guessing that everyone's mileage will differ. But, the bikes are capable of the 40 mpg achievement. I have an old publication where the test riders got this mileage as was claimed by Yamaha.

I do notice a lot of posts here where guys are getting 25-30 mpg. I have to assume that this is a combination of riding habits and tuning.

Plugs look like this:
