Is there any difference between the
OKO K-102 24mm FLAT SLIDE POWER-JET RACE CARBURETTOR
and
NEW OKO 24mm FLAT SLIDE POWER-JET RACE CARBURETTOR

both sold by the same supplier with a difference in cost of about $20
It can't just be the float bowl as the 102 comes with either

I thought it was the float bowl, it may be just a marketing ploy, you may have to ask them and see if their answer makes sense.

Anyway they get modified so it probably doesn't matter much. We use a plastic bowl to check the actual float/fuel hight and the metal one out on the track.

Don't forget to get a flange type rubber manifold for it too, the original GP one is to small for the OKO.

ProbabLy is just the float bowl. You know you want the flashy clear one. Get the black carb to go with, looks cool so must be faster.

I know why you want me to get the clear one and it is just not sporting!

I have asked the question of the supplier so should get a diffinitive answer over the next couple of days,.. Black would look cool with my planned colour scheme

I don't know the quality of these but i seen somewhere how to pick the better ones it was something to do with not having allen Screws and something else i forget.

These cover a wider range of sizes than i have seen for the ones on the net elsewhere.

Available here http://www.akunar.com/CARBURETTORS.html

Also here some Honda stuff whats the secret HRC

Yoichi Oguma was the Vice president of HRC was hands on and often seen at the track.
He retired the next year early to have his back fixed.
He was one of the original Honda NR500 test riders he gave up the test riding after testing one of the original NSR500 for built for Freddy. I Don't blame Him either.

The page that didn't fit plus some other stuff including something that backs up Dave's claim that they are in bed with the devil.
Kenny Roberts quotable as always.

I don't think Honda did have anything that special other than a well developed bike
It did have a ignition and power valve curve which was adjusted dependent on what gear and throttle opening, but i guess they all had that by then surely Cagiva did I think and i hope Yamaha did.
I guess the ignitech could possibly do this Wob?
Also is the last page i had lost from the plating article it has the squeeze form liner but alas the sizes.
it is also interesting re the die casting and plating.

and the lack of powejet circuit?
i've a motoforce 24mm, didn't know it was a motoforce until i got it, filled it with much better oko jets, the motoforce jets were plated with some sort of shiny/silver stuff and the oko jets were good old fashioned plain brass. the thread in the big nut on the float bowl is horrendous.
next one will be an oko

I work at Asaka, ( actually it s asakadai , next station up ) and I can vouch for that article ,

Photos are banned and as much as I try , no joy in getting in

seriously it ain’t flash , you have the skills in Christchurch to do better , if you lot weren’t so individualistic

I remember one listening to the Engineer who designed the cbr 6 , going on like it was the best thing since sliced bread , and me thinking that there was better being built opposite the boat sheds

Which boatsheds Stephen? Are you referring to the ChCh public hospital maintenance workshops by any chance ?
And getting any two Kiwi motorcycle racers to co-operate on a project is nearly impossible unless one has money....

Here is the air corrected powerjet setup - I have a pair and will test these on the first F3 - 400 engine on the dyno

Really? I'd seen this ages ago & dismissed it as marketing hype, just sounded too good. But open to hearing if there is something to it.

Funny shit, completely independent of that my Dad and I had thought of doing a similar thing. When I was repairing the broken powerjet takeoff on my carb we were talking of the possibilities of adding a mixture screw to both the power and main jets. It got put on the "Maybe try it one-day" list.

[husaberg]

It seems little Jon was indeed less tactful than talented.
Who would have guessed that
Was the Honda entourage really that small for Doohan?
I will add the Kenny Roberts training regime later i had heard of the ranch and the xr100's but never seen how it all works.

After reading this it looks like i won't make a world champion any time soon.
Kenny rated John ahead of both Lawson and Rainey at the time on the dirt track.

did you get my message ok ...all good?

[husaberg]

did you get my message ok ...all good?

Yeah Pm ed again. All Good Hush Hush. Its a secret

I mented the VP of HRC and the NR500
The NR500 had something i believe was the first use of something that all the Moto gp bikes, i think now have, Virtual choc fish for anyone who can guess what it was?

ps it is not carbon or USD forks or Valves cams etc either

Hint it is to do with the fact it had virtually no flywheel effect.

Attachment 0

It failed, but a least they tried to do it as an even match 500cc vs 500cc

Little RC planes have a right angle fuel adjuster screw/tap thingies with needle valves. I'll try and dig out a photo. but it would be very easy to introduce one into the mix as adjustable power jet.

Roberts fell flat on his arse when he had a go of making his own engine. Wasn't until he hired (ironicaly) Oguma-san and ex Yamaha GP engineer Yoda-san(I forgot his firstname) they redesigned the engine to be shorter, narrower and increased the V angle and incorporated a balance shaft did that Modenas start to go like a GP bike. The shorter and narrower engine allowed a longer swing arm which gave better traction made it handle like a GP bike. That all came to naught when the 4T rules were announced a short while later . In which the cycle began again, best results were with the HRC V5 and some pointers on frame flex.
HRC always seem to perform best when there is a stern hand on the rudder, though with a smart cookie like Nakamoto they should be winning for some time to come.

A Zeeltronic has Pulse Width Modulation (PWM) on soleniods (can use air or fuel), to map in each gear with the Ignitech RACE you need to install a 6 or 5 position switch. The NSR250 has on standard as a part of the speed limiter the RGV has one as an optional race kit part. Both replace the neutral switch at the end of the shift drum. Would not be hard to make just time consuming to get reliable.
