my day

[Bob KellyIII]

Wow those are really bad ! I can't wait to see the results !
you might use a heat gun to heat the carb base to get the jets out !
I've snapped off pilot jets before in carbs like that !!!!
good luck !

Bob......

[ducatiman]

were in such poor condition, achieving throttle plate/shaft motion took awhile. Both carbs were frozen solid. Note "were". Jets out/back in after my normal treatment. Getting there, need 1 more day to complete them.

[ducatiman]

followed by ......note pic prior to bench synching and setting float levels via wet testing...both ONGOING

[ducatiman]

the next victim chosen...................

[ducatiman]

recently did carbs for a certain EX500 owner, he reinstalled them yesterday, became anxious to hear it start/run......however, without the OEM air filter.

He reported the bike started/idled ok, but upon throttle, puked at 1/4 to 1/3 throttle.
Answering his text, I made him aware that the filter supplies somewhat of a restriction, which the carbs require by design. I suggested he give it up till he had the "missing piece" installed. Today he texted, reporting it "passed with flying colors".
So I offer y'all.....keep in mind the difficulties running without airbox or filter, or testing carbs without same.

[ducatiman]

currently doing a set of 250'S..... an in process pic attached, more to come tomorrow.

[ducatiman]

TUNING BRASS ready for installation. Posting here for the owner.

[Bob KellyIII]

You must be looking at the tiny pilot screw orings, top/right side of carb in pic.

[ducatiman]

yah that must be it ! I was thinking man it would be a bummer to loose a BB
from that carb..... but it's not ! just o rings ! whew !
I lost a BB out of a carb on a pinto one time and obviously it didn't work after that I found the right size from a bicycle and got it going again ! and the kid never noticed it ! LOL.... dirt floor shed at the time that sucked !
.....
Well done Gordon ! you do exceptional work !
Bob.......

[ducatiman]

ty, BK.

Yet another set of 250's on the bench today.

[ducatiman]

finished up the aforementioned 250's today

[ducatiman]

"Work" was forgone today in favor of watching both NY Yankees and NY Mets opening day MLB games. More will follow tomorrow, stay tuned.

[ducatiman]

completed my #106 refurb today, start to finish

[ducatiman]

per owner request, i returned a carbset from Dynojet kit back to stock within a refurb today. Note stock brass after my usual attentions. A long day here, got a long ride in too!

[ducatiman]

no carbs here ATM, targeting front brake pads replacement followed by full (all 4) bleed on my Toyota Matrix this afternoon. Edited.....too cold today, can wait for some warmth another day.

[ducatiman]

Ducati carbs nearing completion today, currently waiting on correct sized main jets.

[ducatiman]

Completed a set of 500's this morning. Carbs in my posession less than 24 hours, already shipped back home.

[ducatiman]

so far, finished an EX500 refurb (pictured), still working on a GS850 4 banger AND Bob Kellys' 250 arrived for intense scrutiny.

[ducatiman]

knocked the GS850 4 bangers off today.

[ducatiman]

todays victims

[Bob KellyIII]

LOL they Look Brand new ! good work Gordon !
.....
Bob.........

[ducatiman]

insides as well, ty BK

Upon opening, found the decel valve diaphragm was firmly attached to body, ZERO movement. And both floats offered vastly differing heights. Both issues corrected, should be fine runners now.

[ducatiman]

an EX500 set completed today

[ducatiman]

been awhile....bad news to report today.

A completed (refurbed) EX500 carb set has disappeared from USPS tracking while en route back to owner. First time this has happened in all my time doing this stuff.

Giving it 1 more day to show up....but if not I'll make good by shipping a replacement refurb from my stock at no charge to the very patient owner.

[Bob KellyIII]

Man Gordon that is very nice of you !
as many times as you ship stuff you know it is bound to happen...by the sheer odds alone if nothing else....the worse part is they probably will never be used
for anything now.... and wind up sitting on the thief's shelf. but he's got another box stolen ! damm mail thieves need to be drawn and quartered !
....
Bob......

[ducatiman]

been awhile........

Did a Yamaha Mikuni carb from an ATV today, float seat was destroyed by a PO, thankfully replaceable. Done, completed and even wet tested to assure no leaks and a perfect float level. Should be a bolt-on runner.

[ducatiman]

doin a set of 250's today. Some pics.

[eltel]

Cleaned the carbs, reset float bowl height and replaced the rubbers between the airbox and the carbs. That last item made a great difference. The old rubbers didn't look too bad but the close fit of the replacements sealed them tight. I could never quite get the old ones to sit nice. This bike only has 6K miles on it but the clutch must of had a hard life from the previous owner who put 5K miles on it. The friction plates were worn below limit and the clutch springs were below minimum length. Although it wasn't slipping the feel on the new clutch is much sharper now. Plus I treated it to Castrol Power 1 Racing (which I think is the equivalent to Castrol Power 1 Stateside).

[ducatiman]

Ducati carbs in the house for a full refurb/split/clean

Made some headway today. Look like new, yes?

[Bob KellyIII]

Yes ! very nice !

[ducatiman]

performed a refurb on a Honda XL600R single cylinder/twin carb finished a few days ago. Found incorrect, undersized pilot jets, whacked out float/fuel levels.
Made corrections, delivered carbs and actually worked on the bike locally, owned by a good friends boss. Reset tight valve adjustments then reset fuel/air ratio (via the piot screw) and idle speed while running.

Fully successful, no more stalling, even starts up easier.

[Bob KellyIII]

was that XR600R a stock bike or were the carbs added by the owner ? never herd of a single with twin carbs...except for home mods !
... one thing for sure single cylinder bikes can take alot of abuse in the carb department....knowing that most carb problems are self induced i haven't touched the carb on my XR650L ! LOL and it still starts and runs like a new bike !.... when in doubt don't touch it Bob ! HAHAHAH

[ducatiman]

specifically an '85 XL600

the LH (master) carb contains both main, idle and choke circuits...the RH secondary carb slide is timed to rise later, without choke or idle circuits. All factory designed/built.

[Bob KellyIII]

thanks for the info Gordon ! an interesting design and I bet it was an animal in the dirt too...
....
Bob.

REFURBING a single carb off a Honda VTX1300

pics to follow

[ducatiman]

oh oh, trouble in paradise....a frozen in place pilot screw required drilling and an easy out to remove

A carb kit has been ordered for needed orings and pilot screw as well. In the meantime, cleaning all disassembled components.
