Flat @ WOT.PWK Your thoughts, please. UPDATE

Speaking as someone who likes to fabricate things and do everything myself, I've found that a sorted complete carb kit is going to cost less in the end. If somebody doesn't put any value on professional expertise then there's no changing their mind.

So, Mr. Carbon Fiber, please tell us your name.

Don't hide behind your keyboard if you know so much.

I bought a set of flat slides from Jim Schmidt here on this forum back in September.

They say PWK on them and nothing is filed off, removed, defaced, etc etc etc etc

He has stood solidly behind them in every possible regard.

They are fabulous. Much superior in stable idle and performance to my twin Amal set up.

They flow really strong, for the first time I feel my motor and carbs actually match up well.

Yes, I know there are many here who love their Amals, fine, great, happy for them.

Nobody is telling or even advising them to change from their Amals.

Jim's flat slides are not intended for those who love their Amals.

BUT, if one wants a dual carb set up that is superior in solid idle, no gas tickling, and great flow (all just my opinion), then these

well sorted out flat slides are worthy of serious consideration.

Have a look at the choke side of the carb just above where "PWK" is cast into the carb body. The flat area here is where the "OKO" branding has been removed from. If you are happy to buy something which seems to purport to be something entirely different (Keihin I would imagine?) then no problem at all, but as OKO is certainly comparable to Keihin anyway, I cant see any real reason for removing the branding.

You dont need much knowledge to work out that several people are selling OKO carbs in the US, that have had the branding removed. As your company seems to be one of those doing this, then perhaps you could explain the reasons behind it? Also I wonder why there is any need to suggest the OKO is a 2T carb, and that it needs to be "redesigned" to work on 4T motors? Probably though the price of $455 is quite reasonable, as there are quite a lot of additional parts required, which although they are cheap and easily available here in the UK, this might not be the case in the US.

Here are the facts.

I got into these carbs when an american supplier asked for help because they were not working and the jetting and needles were completely wacked. Workable needles were not available from anyone - so I had to design them - think about how much time and testing went into that.

I was told that they were designed by Keihin and were made by contract by another company. Thats all the research I did about the source. I have bought every carb from an american supplier for several times the cost that has been posted in this discussion.

I have not asked the people I get them from about their source. That is their business and I have been gratefull for what they have done for me - it started out by them sending a free set of carbs to me to sort out. I liked them so much that I asked for a dealer account and put them on the market.

I have never contacted a compary called "OKO". But I reserve the right to change plans, make adjustments and buy and sell from anyone I feel like.

I have never removed a brand name from any carb and re-sold it. Brand name removing was first brought to my attention by this discussion thread.

I am learning more about this carb all the time and investing more time into getting improvements for it. I am into it so far now that some momentum has built up and I'm going to ride with it.

I am learning some things through this discussion group that I don't like - but it comes with the territory. I can take the good with the bad and there is always a mix when you are dealing with people.

Even though it is the lowest cost flatslide on the market - apparently thats not good enough for some.

Anyone can reasearch this carb and tell me what they learn. They can market it themselves and come out with their own carb kit. They can find their own source or buy it from the same american supplier that I buy it from. They can perform all the same upgrades that I have. But I'm not going to give them any free help or make it easy for them. They will have to plow through everything I had to go through. There are those who just talk and there are those who "do". I'm one of the do-ers.

Jim

Look at the stuff JS offers, look at his approach to quality.
Plenty of people make stuff for Commandos, few approach
what he can do.
You don't like his wares or his prices? Fine . Trade elsewhere.
When I get up to the engine in my rebuild, Ill be a customer.

Jim, for the record your stuff is top notch including the carbs and related setup and some of it is just damned incredible (cam kit).

Although I do not own this thread/topic, I did, however, start it and it's open to all sorts of milarky. As far as CF goes, the more we feed into CF's conversation the worse it gets and when CF sinks his teeth in .......well.......I've never seen CF let go. Whisper "tank sealer" in his or her ear (seems a little bitchy IMHO) and see what happens. He/she may be quite knowledgable, just misdirected.

There are many who would like to know where he/she, CF, lives. Why is this? Do they want to bring him/her gifts? Some beer/wine? I just don't know. Maybe to see his/her Norton Commando. It must be too good for us to see posted here.

Jim, you have been totally supportive and I thank you.
Keep up the truly great work.
Peter

Hi there, let me add that I totally agree with Jim Schmidt, he is the sort of guy who help us to make our Norton to perform better as some others , and in such a small world i do not think it is fair to attack him on his business.
Yes , it is a business , and since I am in Norton, I always feel happy to see some guys trading spares , when I need something , I think about first , then count the money in my pocket, and if it's OK , I go, but never I complain after , it's my life , I am adult, and they are my toys..........this life downthere is pretty short.
So Mr Carbon, if you have better deals , propose them , but please be positive , don't go again like you did against Hobot, we are all different , but i am sure you know lot of things , so don't be so shy , and show me .....I am just 56 and now in Norton since 1974, and I don't know everything..........
I am sure that personal attack could upset some people and so they will not come anymore on this forum!
for a long time we had the pleasure to look at Ludwig's post , now where is he , may be someone upset him ???
On another forum , there was a very clever guy : beltdrive man , where is he ??
Keep cool , and take it easy , just like me , and few others........Pierre

Personally it is just irritating when people can't post any BASIC info like GENERAL location and a name and expect to participate in a public forum. I think it is just a paranoia thing and every forum has a personality or two like that and for the positive comments about Jim, I agree 100%.

Well then Carbon,

Since you know so much about the cost of every item in a twin flat slide setup and since you have spent the time and field testing to sort and fit every jetting component, why don't YOU get in the business and make the HUGE profit that you believe comes from selling them YOURSELF?


Either that, or shut the hell up until you demonstrate the depth of knowledge and real world experience required to put together and market aftermarket parts for Commandos.

OKO carbs are a quality item, but I just cant see the need for removing the branding?

Give it a rest, it's beyond tiresome.

We hear ya,CF.
Hey LAB or Jerry, My problem is solved, all is well, feel free to go ahead and zonk my topic here. I can't take it any more. I realize I could use the "foe" option but I just don't want to go there.

Re: Flat @ WOT.PWK Your thoughts, please.

Run at WOT for 5-6 seconds. Then back off the throttle to about 7/8 and hold it there.

Does the bike run better at 7/8 throttle than wide open?

If so, your main jet is too small.

Go up a size on the main, and repeat the test.

Best of luck.

Hey brian!

I don`t think so….i think it`s reverse.
When the bike pulls better when you drop from full throttle to 7/8 throttle:
The mainjet is too large! A smaller one is needed!

Because in such a case:
you minimize the flow [gas] passing through the mainjet when you drop to 7/8throttle ……
Situation is when you drop to 7/8 throttle:
you get a better mixture for your bike where it pulls better….
In this case it pulls better with a leaner mixture! -----smaller mainjet is needed!

Try it!
Think about it…..sounds more logicaly for me……and it works with my amals as well with my mikuni rs flatsliders!

Have a nice day!
chris

No sorry Chris, but Brian is right. It basically means that at 7/8 throttle the engine is getting all it can get and needs more fuel to go any better.
If the main was too big the engine would be blowing black smoke. Go up a couple of sizes to make sure you notice the difference and test it up hill
or with your mate on the back, or both, so it really has to pull hard... keep going up two sizes at a time until it is blowing smoke or becomes
noticeably less powerful, then come down one at a time untill you are happy.
Theoretically you could run without a main jet, if you never went over 3/4 throttle opening.
AC. P.S.... Just went back and re read the original post. Does sound a bit like air cleaners or restriction, although there would probably be smoke.?
Always test without air cleaners if possible. Starting to ramble.. sorry.... Good to see you got it right pviss.

If the OKO carb you have has not had the fuel inlet ports modified, then its possible that fuel starvation may be a problem when running on the main jet for any length of time.
