Okay, so I've owned my 2000 W650 for almost three years now and I've had a love affair ever since I laid eyes on her. However, I've constantly dealt with carburetor issues the whole time. The bike would never run right. I experienced surging, dying constantly when pulling out...I'd have to give it a lot of gas to keep from stalling, very very cold natured, and just an overall PITA I still loved the bike though, and nothing could cause a bigger smile than riding the back country roads here in Middle Tennessee.

Well, finally I took my bike to a carb expert. The guy has been working on bikes longer than I've been alive, plus the guy is like a mechanical engineer. Needless to say he promptly told me that the carbs for the W650 were woefully under-engineered. He worked his magic and now my W650 and the two W's my father-in-law owns run like dream bikes...better than new

If I'm following what he said he had to do: he shimmed the needle, synced the carbs, and said he drilled the holes in the bottom of the carbs to be bigger. He explained something about gas flow in/out of the carbs...but I'm too simple for all that. He said he did something else, I know it wasn't rejetting them, but anywho...I'm in love twice over now!!! The bike runs the way it always should've run.

It's not that the carbs are under-engineered. They are in fact Keihin carbs. Keihin is a respected Japanese fuel system supplier that puts out all kinds of top-notch carbs and fuel injection systems for a whole bunch of motorcycles out there like the carbs for our Kawis and the fuel injection for my Triumph.

What the carbs are, though, is set way lean from the factory to meet emissions requirements. This leads to the big being very cold-natured, taking forever to warm up on the choke, certain driveability issues, etc.

Sounds like your guy did the common mods that we tend to do to ours. Shimming the needles allows for a bit more fuel flow at the higher engine speeds and loads without re-jetting.

As for drilling out the holes at the bottoms of the carbs, presumably he drilled out the caps that were installed at the factory blocking access to the pilot mixture adjustment screws. Once the caps are drilled out, you can adjust the pilot mixture with a screwdriver to a certain extent. And this is the adjustment that will net you the most benefit in terms of the symptoms you were seeing: cold-bloodedness, hesitation, stalling, etc.

The pilot circuit is the part of the carb that supplies the fuel/air mixture for idling, low engine speeds, and a lot of the steady-state cruising operation where you were seeing lean symptoms.

Adjusting out the pilot screws a bit can solve a lot of the ills if you still have the stock exhaust. Sounds like that's what he did.

Sounds to me like he just tuned the carb to run properly instead of the lean stock setting to pass emissions. It is pretty easy but time costuming and takes some experience and the right tools. I tuned my carbs and it is very smooth..sometimes I forget that I'm on a 675cc parallel twin it so smooth.

sounds like he killed your bikes personality quirks and made it boring.

I got a "Sigma-6" Kit - upped the pilots & main jets a bit - didn't need to shim the needles (or drill the slides), totally transformed her, no more hesitation or 1/4 hour warming up - all standard pipes & air filter


All you need is a couple of larger mains + pilots

I shimmed the needles, very easy, first time I dared to work on a carb. Also drilled out the covers over the screws and adjusted them 3 1/2 turns out.

I did them both at the same time, so I can't say if only one or both caused the transformation, but the difference was amazing.

It went from a bike that would barely stay lite from cold on a freezing winter day, to a smooth running non hiccuping bike.

My skills are minimum, so I'll use the oft repeated, "If I can do it, anyone can do it".

Unfortunately, the "Capt. Jake" site that had a step by step picture tutorial for shimming the needles, that I relied on, is not longer up. But here is the one for the adj. screws: http://www.captainjakes.com/w650/fue...elscrews.shtml

So I pulled off the vacuum hoses from the carbs the other day in order to connect my carb sync tool and I noticed that both vacuum nipples were damp with some sort of liquid.

I didn't really think anything of it at the time but for some reason I was just thinking about it and had a "wait a minute..." moment.

Those shouldn't be damp at all, unless...some fuel is getting past the vacuum diaphragm in the petcock.

Oil vapor from the crankcase breather wouldn't be making its way to the outside of the vacuum nipples. So what else could it be? What am I missing?

Anything to do with your blocking stuff with marbles? Condensation?

What did the liquid smell like?

Nah, that stuff has long been properly removed. The only thing connected to the vaccum nipples now is the hose from each to a T-connector which goes straight to the petcock.

No obvious sources of condensation.

Yes that's the obvious question but of course I wasn't thinking at the time so I didn't bother to check! I will do so next time I get a moment to work on the bike.

Wicked Whatever Happened to the Pacific Northwet Dubya Wrally?

Good grief, time flies so quickly and I've been such a bad boy . . . .


We should call this the "Mountains to the Sea Tour."

The "Wrally went off as scheduled, with orsurf76 and RetroRuari arriving Friday afternoon, 15 August. Ed and his lovely bride showed up shortly after, but since he's just on the backside of a bad case of bronchitis he elected to drive . . . and listening to him cough I had to agree!!

orsurf76 made himself most useful cooking the brats and burgers that night, and Ed had brought some excellent liquid refreshment from a couple of craft breweries in his native Bellingham. The "barely sodas" were most tasty!

(Note: The photos are by me, RetroRuari, MauiRob, and Jane . . . Ed's better half).



Next morning found cloudy weather, but no rain in the forecast. Bacon, eggs, hash browns were eaten, coffee was drunk, Dubyas were saddled, and we were off to meet up with MauiRob and climb the roads to the mountains.



Of course, being motorcyclists riding small, fun, cool bikes, we didn't take the direct route but skittered along small country roads south of Port Townsend to take in the local color. (Note: If you see bright blue skies and sunshine--and no Dubya riders--the photos were taken the next week when I rode the same route and took the time to stop for a couple of cool photos . . . ).



MauiRob told us the interesting story behind this road's name. Turns out the road was named for a book.

"The Egg and I, first published in 1945, is a humorous memoir by American author Betty MacDonald about her adventures and travels as a young wife on a chicken farm on the Olympic Peninsula in Washington state." Wikipedia

The author lived on this road, so it was named for her book.

I'd mentioned local color, so here it is . . . .



Olympic Peninsula soils are so rich and fertile you can grow just about anything.



Not the most modern of motels, but perhaps one of the coolest around; the place is full of whimsical rockwork and funky decorations. If I didn't live so close I think I'd come over here just to stay the night.







So of course we all took photos of the place. RetroRuari and MauiRob . . .



orsurf . . .




The local Jamestown S'Callam tribe does roadside rest areas right.



And off like a flash . . . to Sequim for more coffee. Seems like RetroRuari likes his espresso, and we all were most happy to join him. For those of you in deprived parts of the country, drive-through espresso joints are just about as common around here than gas stations . . . high-test for both you and your bike!



Drinking and taking photos at the same time, dunno about that. Ruari's photo of me taking the picture above. Coulda sworn I don't look that old.



Then on through Port Angeles and a left turn up Race Road . . . to the line of cars waiting to drive up to Hurricane Ridge on a summer Saturday morning.



As it turned out, it didn't that THAT long to get up to the entrance station, pay the Park piper his due, and travel up the sometimes very foggy road to the Ridge. (orsurf had his video camera on . . . hope he can post a clip or two of that ride up). Glad the Park Service sees fit to paint good center and side lines 'cause sometimes that's all we could see.

The Visitor's Center parking lot was crammed with touristas so we motored blithely through the crowds and rode onward towards a small picnic area on the little road to Hurricane Hill Trail. Much less croweded!



Our picnic was notable for the swirling clouds rising from the Elwha River valley far below. It wasn't cold; the temperature was quite pleasant in fact. And, to me at least, the rising mist has it's own charm. But we didn't get to see the peaks and mountain ridges for which this viewpoint is famous. We're a mile above sea level here, and less than 20 miles from Port Angeles.





Wonder what kind of motorsickle MauiRob likes?



orsurf enjoying the view.



MauiRob at the picnic . . . .



. . . .and a moocher. Sorry sweetheart, but the only animals we feed are ourselves!



After chow, an hour's saunter down the mountain, back through Sequim, around Discovery Bay (Where the honorable Captain Cook anchored his ship while he explored the area in small boats), delivered us to North Beach near Port Townsend on the Strait of Juan de Fuca. To our pleasure, sunshine had begun to leak through the clouds when we got to the bottom of the Ridge road and the beach was invitingly warm.



RetroRuari, MauiRob, and orsurf76.



Perhaps I should send this photo to Aerostich? Yep, the Combat Lights are waterproof.



A wonderful dinner at an Italian place in Poulsbo that MauiRob recommended, then towards home for Ruari and one more night in my yard for the rest . . .

Ruari's bike en route Victoria on Sunday . . . .



And on the fast ferry heading north.




I had a great time with everyone who was able to come . . . Acquaintances from last year and new friends from this year. The weather was decent even though we didn't get the mountain views like we did last July . . .

I rode up the next week on the GS and this is what y'all missed . . .




Hope to see everyone next year . . . we're thinking about a Bellingham meet-up and a ride up to Mt. Baker.

Aloha!!
