Oh well...we can always dig around here I suppose - https://jrcengineering.com/technical-support/jrc-pwk-carb-instructions/

Was that the "Boss Hoss Blue" or the "RT1200 Uber Alles Blau" you used? Stands out well from they grey background!

[viczena]

I just dont know what you are talking about. Maybe the blue colour dizzes your mind?

@ #16: Did you write the response at #14? If not, I can see the confusion.

These folks can help : https://www.blublocker.com/

Not sure if they'll help with the dizzy spells though. Best to avoid operating motorized equipment until that clears up.

Yes, #14. "I'm afraid my notebook went to the new owner, but JRC was helpful with jetting."

Therefore you have to wear sunglasses. Or you wear sunglasses? Or want to wear sunglasses?  It gets more confusing every time.

Maybe its really the best if you avoid operating motorized equipment until that clears up. Sounds like a good idea.

@ #14 was written by Stanley. So you're Stanley, not Viczena? This is getting deep! 

I think what was actually going on @ #14 was that Stanley was poking a bit of good natured fun at me for using blue font. Now we're ostensibly embroiled in a discussion regarding the theoretical effect of blue light on cognition. I have copied in a reference regarding possible effects of blue light, left in black font so as not to trigger an adverse response.

" Blue light is the most likely to trigger photophobia, migraine attacks, and other symptoms of chronic conditions (including vertigo, dizziness and disequilibrium). Plus, these wavelengths are literally everywhere...in fluorescents, device screens, and other forms of artificial light. "

BUT in the JRC instructions (when you gentlemen have quite finished), if you scroll down you do indeed come to some settings PWK carb settings for the Indian-built Royal Enfield Bullet. The 350 and the 500 AVL are also included, but THIS is what the original poster is looking for!

Thank you for the link!

A.


Royal Enfield 500 (Iron Barrel)

Carburetor size: 30mm

Pilot Jet: 35

Main Jet: 138

Needle: Standard

Needle Position: Center

[viczena]

@#19: So now you are triggered by photophobia? Explains a lot. But what has your malade to to with Royal Enfield?

[AzCal Retred]

Ha Ha, Touché, Adrian II! Glad we were of accidental service. Sorry for the misappropriation.

Viczena, continue on:   " Denigrating all things Swedish "? It seems appropriate for this level of discourse.

[viczena]

So what has sweden to do with the topic? You seem more and more confused.

[AzCal Retred]

The only guy confused here is busy burning up bandwidth answering my reply to Stanley's post #14. Are you "winning" yet? Any more phrase inversion "zingers" to get out? This isn't adding value to the Iron Barrel section, it's just spleen venting. The Campfire Talk is a better place for this, "Denigrating all things Swedish" seems about the right box for this level of discourse. No reason to muddy the water here even more.

You say the carb on it (presumably the Mikcarb) was utter crap, Why?  Is it worn out, broken or just not setup right.
If it's just not setup then it is easy to sort. 
I had rarely played with carbs before my Enfield and it was shithouse, but I have sorted the Mikcarb with a little help from the brains trust on here.  It is now very well behaved, no backfire on the overrun and smooth delivery throughout. 
Just a simple change to the pilot & main jets - with a little trial & error.

My PWK 30 with a glued on flange has operated perfectly for the last 15 years. As an aside, what is the difference between a 2 stoke carb and a 4 stroke carb that you guys speak of?

Can you tell me if your needle has a code on it? (f.i. JJH?) i am wondering if you can 'secretly'convert a 2 stroke pwk to a 4 stroke with only a different needle.

Normally, there's more difference between a 2/4 stroke carb (venuri, atomiser)

[winsun-enfield]

I was wary of the Chinese-made copy of a Taiwanese copy of a Keihin, so I went with JRC's Taiwanese copy. They offered me the jets to tune it but I got them on eBay from one of many suppliers. My bike ran fine after fettling with a main change and needle adjustment. The JRC bolts right on and negates the need for a leak-prone rubber hose.
I would avoid any PWK sold for $20.

But, the JRC's are NOT 20 dollar copies with a flange glued on? Is there more difference??

[Stanley]

My choice of carb was based the observation that every Taiwanese product I've encountered was on par with Japanese products. BMW and Piaggio use tons of Taiwanese components including engines.
The Chinese PWK copies are packaged to resemble the Taiwanese carbs but with small clues that can alert the buyer to the poorly made Chinese cheap copies with generic jetting. The defects of these "$20" carbs are often the fodder of motorcycle fora and blogs.
JRC sells Taiwanese carbs jetted for specific bikes and fits them with a flange that could be called glued on but to my eye is substantially bonded. They also answer emails and sell carbs for a range of Brit bikes.
To me, the PWK was better than the Indian copy of an ancient Japanese carb.

BTW, I would have gone for a classic, simple Amal if they weren't so steep.

[winsun-enfield]

Thanks all for reply.
Browsing on ebay you can see pw clones for 2 stroke and also 'universal'

Strangely enough some of them still/do have a powerjet and even rodder in the venturi?

And, i know that (maybe) te greatest blockage is in my head, but given the 'normal' differences between a 2- and 4 stroke carb (you have -at least- to change the needle, atomizer, jets and slide to convert the one to the other) Ho can one be suitable for both?

I was searching for an OKO 30mm, made in Taiwan, whithout powerjet,for a price you can expect some quality (around 40-50 bucks) but did not succeed yet in such.

Is the -far more expensive- JRC carb nothing more then a cheap OKO with a flange glued on them?

I've had several bikes with amal carbs, besides they seem to wear out fast, they seem very crude and hard to finetune..
