my day

[ducatiman]

Thanky Mav. What massive piles of stuff comes offa these, consumed my entire workspace! These were truly challenging.

[ducatiman]

250 ninja with way oversize #50 pilot jets, returned to OEM 38

Ready to rock again!

[ducatiman]

refurbed a set of EX500 carpo-traitors today

[ducatiman]

Today sold and shipped the 500 carbs pictured above (were my property)

Those look GREAT....wish I had a set like those...........

[ducatiman]

wishes often come true

as clean in as out...fully functional, set up, ready to bolt on. The owner must endure the extreme task of setting his idle, though.

Added a gut shot (make you envious of owner)

Gordon........do you pack a spoon and a fork (or, perhaps a "spork") when you send them back to the rightfull owners....???

[ducatiman]

look good enough to eat out of, eh?

[ducatiman]

A "recheck" completed today on Holley carb model 1904 from a 1958 Ford F100 pickup truck
Found a shard of glass in fuel intake path, otherwise ready to go. Old reference material needed to confirm all components were accounted for and in proper placement.
Interesting old tech.... 1 main jet, accelerator pump, using various ball type check valves of various sizes, in multiple spots. Some use set/return springs, some "float" ...hence the need for an old 50's era manual.

[BloodFX]

This is my carbs when I bought my el250 27 years old lol.
Not as clean as yours but a damn site better after hours of cleaning.

Paging Dr. Ducatiman1 to the Courtesy White Phone......(in other words, check your home email, buddy!!)

[ducatiman]

EX500 carb refurb underway.

Beyond 2 clogged pilot jets, 1 carb pilot circuit was badly clogged, now cleared.

Some in process pics'll follow. I predict the owner will be pleasantly surprised, a dramatic transition underway, affecting both functional and visual levels.

[ducatiman]

ANOTHER snowstorm underway here...figured I'd complete these 250's I started yesterday. After full resto....look like they came outta the Keihin factory just a few days ago. I'll predict bolt on runners with a very long service life ahead. In addition petcock innards inspected and confirmed operational as well.

[ducatiman]

A few 250 observations. Of late I'm finding the mesh fuel strainers, which should be inserted into the black inlet rail, to be pushed out of place....crumpled and way up a few inches into fuel lines. These are no doubt causing fuel flow issues.

I've discovered the Kawasaki factory EX500 fuel rail filter to fit *much more snug* and not pulling out every time the fuel line is removed.

I stock them and will offer the install option within my services going forward.

But owners need to be aware, I'm finding this a common issue. FWIW...YMMV
***********************************************************

Another 'trending" discovery, long term parking on sidestand. Within many carb services I'm encountering contaminants (damaging liquid additives as well as varnish) greatly affecting the LH carb moreso than the RH.

I'd suggest long term storage using centerstand (if so equipped) or an appropriate block of wood under sidestand to somewhat (safely) level the bike somewhat. I repeat....FWIW...YMMV.

Good info, Gordon........something every "current EX250 owner" should pass along if/when the bike is sold to the next owner.......

[ducatiman]

not limited to 250....i'd apply it to any carbed bike under long term storage, if not draining bowls entirely in anticipation.

Some lean way over too, due to suspension mods or various other reasons.

[DannoXYZ]

yeah, factory config leans way over. I park mine with sidestand on a brick

Are these Joey’s? If so, I hear we’ll be seeing them soon and looking forward to it. I’d be interested in hearing what was troublesome with these. I put those in my ultrasonic cleaner when I bought the bike in 2018. The previous owner did some tinkering and it wasn’t running when I got it. I sold the bike to Joey in December 2019.

[harleystyles]

Yep they are mine. I'm looking forward to getting the bike back going again.

[ducatiman]

main issue included accrued varnish resulting in float valve and pilot circuit issues

pic= 1000 words (Joey is in possession of numerous in-process pics)

[ducatiman]

Today safely extracted this faulty pilot jet, replaced with brand new jet... thus saving the carb body.

Extracting stuck pilots from deep within always a heart pounding experience...though it came out in segments. Hey, whatever it takes.
Carb body threads verified undamaged, circuit confirmed clear and ready to roll again.

Note carbset received this morning, shipping back home this afternoon.
Same day service. Try that at your local HonZuKawi dealership.

[Moto-Kafe]

I never posted "publically", but need to say "Thankyou Ducatiman", my rebuilt carbs by you looked absolutely BRAND NEW!!! I have rebuilt carbs (mainly cleaned), but NEVER to the level that he takes his rebuilds. All guts are new, nothing just "cleaned and put back in". It was well worth the $$$ to have it done professionally, and the idle/running of my carbs now prove it!!

[ducatiman]

thank you for kind words, glad the refurb worked out so well. At your service during your next upcoming project, if necessary.

[notunderweight]

Wanted to briefly echo Moto-Kafe's sentiment here - This is now the second time that ducatiman has provided a fantastic, professional service for me. Both times - carbs look straight out of the factory, run straight away, and keep running... Not to mention his skillful surgery on my stripped pilot jet
1 day service!
Bike is running great now, looking forward to nice riding weather. Can't say enough good things.

[ducatiman]

today finished a Honda CB360 twin carbset from 1975. Yep, 46 year old Keihin carbs there!

[BloodFX]

I'm gonna buy a soda blasting setup in next few weeks to blast carbs, got any tips for a beginner?

Update. I finally got off of my duff and put Nina the Ninja back together this weekend. Carbs went on and fired right up. No tuning required, although the next time I find a little time I will fine tune the idle circuit as Ducatiman instructed. She is a TOTALLY different bike now. Absolute hoot to ride.

[ducatiman]

glad it worked out! enjoy

[ducatiman]

leisurely doin' a refurb on a set of EX500 carbs today.

Unannounced, my neighbor brought his non-running pressure washer over, I found a clogged tiny main jet in the *plastic* carbed BRIGGS engine. Now a one pull start and runner.

Finished the 1st 500's, then onto a 2nd set in house.

[myates92]

@ducatiman you wouldn't happen to have a spare one of these Main fuel intlet fittings I could buy off of you?

[ducatiman]

sorry...no, I don't.

[myates92]

Ok, thanks.

[ducatiman]

another set of 500's knocked off today, multiple issues dealt with.

[ducatiman]

Refurbed and corrected faults found within these new gen 250's today.

All brass came out awesome, wet tested perfect, all should be a "go".

[ducatiman]

knocked off these 500 refurbs today, these my property, for sale

[ducatiman]

cool, windy ride on my SS800 this morning.

[ducatiman]

Red Max EB7001 blower dropped off today. To be serviced, picked up tomorrow, at which time something else will be dropped off.

Back to normal with my landscape contact.
