Matie

Punt nommer een, as jy minder rook sal jou exhaust header al blink gewees het!

Is daar net 3 clip posisies op die needle?

Jy moet die carb diaphram breather filter verbeter. Ek het stukkie uit 'n ou DR lugfilter gesny en met foam filter olie gespuit, voor ek dit voor in die bestaande filter ingedruk het. Maak die ou een eers skoon, as daar nog iets oor is!

Ek twyfel of jou "D" shelf mod gedoen is. Dis hoe die oorspronklike lyk.

hahahah

Ok, ok, ek sal minder rook en meer werk ma!!!!

ek het nie die clip slots getel nie, sal gou vnaaand.

so as ek reg verstaan het die stock plastic washer so n slot in?

ek sal die breather filter vanaand mooi bekyk! maar ek deink nie die carb is al in die agelope 16k km oop gemaak nie!!

chooper gaan kyk op my ander thread: http://www.wilddog.za.net/forum/index.php?topic=170654.0

het elke foto spesiaal vir jou met my asbakkie in geneem!

niks gerook nie en die header is nog nie skoon nie!!!

So pas daar kommentaar gelewer! Gewonder of hulle doelbewus daar geplaas was!

Matie Spero there does not seem to be much of a difference between these two needles.
Stock is about 3mm shorter by the look of it, diameters look about the same and the taper runs out in about the same place.
Can you check them with a caliper and micrometer.

They are as close as one would say in afr : soos damit aan n vloekwoord.

here's two links that would give you the idea, the diff is really not a lot:

OK so the first three are very similar, and the #4DJ is quite a bit thinner on the small end. Like the stock needles that people taper in their dremels.
I think the last needle is going to make the mix richer at wider throttle positions.

yes
yes and yes

I will as well try to taper my stock needle, as I have the factory pro needle that is so close to stock that I can just revert back to that if the taper fails.

I will do a lekker writeup when I finally get around to do this....

the plan will be a double taper, which I will explain later.....

I will tonite try and do all the measuremenst that I require for my thought process.

I think the most difficult part will be the actual tapering, cause the: jas moer it into a dremmel en grind die ding approach will not really work for me

Like #4? It is much like the standard needle up to the last 10mm when it suddenly tapers down to a mm under standard size.

Personally I don't like mucking about with the needles taper. This has been carefully designed to maintain the correct fuel to air ratio at all throttle openings. Raising my DR's needle circlip from middle to lowest groove dropped my bike from 19km/l to 14km/l. I have to assume that the bike must be running too rich now. Imagine what a modified needle will do.

Andre sien onder: Die verskil tussen Andre en matie!

Maar met die afstande wat jy gemeet het het mens geen idee nie.
Ek dink jou naald lyk soos daai toe ons leer vas skryf het, so een laaaaang squiggle!!!!

As jy ooit weer daai naald uithaal meet elke twee mm, en meet van die ander kant af!

Ek worry nie oor Kykdaar se naald nie...ek's net bly Matie leef nog!

Maar ek like die comment oor die vasskryf!

My juffrou het gevra of my skrif geheime skrif is! Regtig! Nota destyds in my boek gewees!

Ek het my agter shock laasweek van Superfoxi terug gekry. Die aand gou terug gesit. Pre load is die "stiff" lengte in die manual. Daar is static en dynamic sag, maar moet dit nog wetenskaplik meet!

Voete voel effens verder van grond af. Hy't gese ek sal tevrede wees!

Vandag ook oproep van ou gekry wat die caliper extension bracket ge-mill het. Ek moet kom loer se hy! Vandag gou in die big smoke gewees. More middag gaan ek loer!

Ek sal fotos neem!
