Hi Leon,
alles klar?
Team Schleenbecker sold me an OBDVR needle for my 501 (2002).
Now the spark plug is dark brown.
They also gave me an PJ #42, but with this jet it is nearly impossible to
start the warm engine, so I changed it to my old #48. It´s better.
I wonder why my estart doesn´t work as good as before. But I think
the main reason lays in a too weak battery. I have some problems with
the battery charging.
Do you have a feeling that the engine could go in higher rpm´s in 6th gear? You mean you still have some reserves but the engine doesn´t manage it?
greetings

at the risk of trying to sound like i know what i'm on about can i just say alles is veruckt!!!!
a bikes jetting needs to be lean for it to restart when hot! so going up in PJ size is the wrong thing to do.
a D series needle doesn't release the power so it must be running lean. to compensate people fit far too big a MJ. get the EKQ like me and you won't look back.

Huhu! 
verruckt hehe, sweet :wink:
Taff´s right Hrib, i went down from 50 to 42 because of bad hot-starting!
Thats pretty much exactly what im feeling! But i also have the feeling that the changeover from the pilotjet to the needle is not right. the pilotjet is correct, plug is deer-brown, as we say in germany.
But the berg stutters a little bit at close over closed throttle :roll:
too lean i think. Will change back to E-series i think. First needle for me was an EMP, too fat in idling, but i think an emr or s schould be right.
Or an EMQ, but then ill need a 40 PJ.
Taffy, whats the advantage of an *K* needle? I know its shorter than the *M* ones, but what does it cause?

Hi Leon,
danke. Haste den in meiner Gallery gesehen?
I know, my van is really conspicuous, in the meantime it is even known in several european countries. :wink:
But that´s not all the time an advantage.
Back to the topic:
Right now I´m also thinking about another needle. Should I buy a OBEKQ?
These little metal thing is very expensive. Only for testing I have to pay 16 Euros.!?
I don´t understand, why my engine starts bad with the #42 PJ. I think I will test it soon again.
I have also the feeling of a little bit too less power. But it can also be an result of the Kokusan ignition.
I don´t exactly know, right now.
Leon, did the OBEMP needle release more power from your engine? Maybe you can lend me yours and I can test it if there is a difference.
Are you collecting needles?
best regards

Hrib,
Just came back from 2 hours of rain-driving through our woods, its cold and wet but very nice to ride at the moment!
I got the coolant-liquid cooking in a very tricky section, after 2 minutes with practically no cooling-wind, guess thats another sign for to lean jetting.
And i broke a mounting point of the rear sidepanel, ****** wet trunk :wink:
To the needle:
Im not collecting them, although a complete set of all needles, Pilots and mainjets would be a dream!
And yes, u can test the needle, i dont think i will use it anymore, as said, the idling is very fat with that needle!
On the other Hand, i GUESS the needle has a better midrange and topend power! But this is very subjective, just what the "Popometer" sais, im really not sure
Another problem is: I changed my Cylinderheadcover with one of a 1997 Berg, because the rockerarmshaft of the 95er has 10mm Diameter, which is produced no more. The 97er headcover has 12mm, and can be bought at moto-rumpf.
Perhaps something with the timing is slightly different. HEY PROFESIONALS, what do you think?
U see, it aint easy at all! :?
But hey, send me a pm with your adress, ill send you the needle!
And yes, ive sean ure bus in the gallery! And i can imagine it can get a problem!
And yes, those keihin-parts are very expensive! I will check the new Keihin-importer (www.keihin.de) but i doubt he is able to sell that thingies cheaper...
cu later!

the difference in the middle code of the needle is simply the height at which two needles are identical!
so
EKQ on clip 4 is equal to
EMQ on clip 5 is equal to
EPQ on clip 6 is equal to
ERQ on clip 7
also that
EHQ is equal on clip 3
each clip is worth two alphabet letters so it is possible to have ELQ on clip 3 and then put a .5mm washer under it. =clip 3.5!!!!
they don't use the letters O and I in the middle suffix ok?
the only other difference is that the needles are all the same length so a needle on clip 1 and a needle on clip 7 will be 6mm apart in length. this has little or no affect at all.
remember the first letter is the angle of taper
the second letter is where the needle is 2.515mm wide
the third letter is the needle straight's width
we pay 30 euros for a needle so don't complain!
get that yamaha needle!

Hi guys,
Leon, thank you very much. I ´ll send you an email. I still have got your adress.
30 Euros for a needle is incredible. I thought 16euros would be very much,
but that breaks every price record.
From that point of view I should rechange to dellorto, but joke apart:
Normally there should be no need for buying new jets and needles all the time.
If one day everything is set perfect, I´ll be happy and that´s it. No more need to worry about anything in this carb, I hope.
I must say, till now I can really call the Keihin carb as easy-care.
greetings

(05)fe550e jetting
We found that the new fe550e(05) started ok and ran just a little lean in the stock form. Took a little too long to warm up and always popped on the overrun. I live a sea level and the air temp is just a few degrees above freezing here now.We changed the pilot jet from the #38( stock) to a #45 and the bike now starts easy on the e-start and first or second kick.......sweet........nsman

keeping this long time classic thread going so.....
took the steed up to R & S performance today before moving on to see my friend in hospital. Sean is a long time friend and we are both good friends to the above so i killed two birds with one stone.
i was there just to meddle a bit and check out my jetting hunches. don't forget it may be a FE400e from '02 but it has the '53' MX cam and a keihin carb fitted. started with std silencer at 35.7 rwbhp.
i had 37.5 RWBHP at the end.
the FC/FX pipe only gained .7 bhp through the midrange which hardly makes it worth it but at least it's actually no noisier than the FE pipe anyway.
the larger downpipes from the 550 (28 id as opposed to 26 id) produced a free 1-2 bhp all the way up to 3/4 throttle
the power curve is like a plateau from 6,000 to the redline.
the main jet came down on this fine crispy clear morning to 160MJ from 162 and should never need to go higher-especially in the summer. ground level and zero degrees celsius.
the needle which was an F** test needle was raised from 5 to clip 5.5 using a washer.
tried a 42PJ with my special needle and it was too rich so went back to the 38PJ. from my results i will be going back to try the 'E' series again back to back with the 'special' as i lost power at 3/4 throttle due to being too rich even though the MJ was correct.
i will wlso try increasing the MAJ size to lean the top end. i'm presently on a #180 which i fitted whilst running the standard '01' cam.
adjusted the cam timing (********) and it was poorer. may try advancing it sometime if i can afford the back to back time.
TBM tested a knobbly shod '02 standard (and rather new) husey at 32rwbhp. and it had a steep bhp curve where mine had a plateau from 6-10,000 revs. that's why i want a little peak infact. i can be in any gear and lug but it used to be like a two-stroke!
so that's it really. the needle was a success but i will try for more.
ONE THING IT DOES PROVE THOUGH IS THAT MY "seat-of-the-pants" TESTING HAS BEEN VALIDATED. :shock: :shock:

i'm digressing here from a straight carb chart but it is a bloody good thread!
first of all i have a question for all you 650 riders! can you give me the i/d of your down pipes please? the 550's are 28mm i/d so i want to know now what the 650's are?
question 2 for the 650 boys is: what is the i/d (top to bottom) of the inlet rubber twixt head and carb at the head? this'll be off the dell orto carb rubber i guess. i think it'll be 33-34mm. can anyone check please?
to finish though i will leave my latest jetting and the bike goes like snot!!!!!!
158MJ
200MAJ
DMS needle
clip 4
35PJ
45 PA
PS = 1.75 turns
wheelies in third gear from stand still no leaning back and in wet grass.
this is fairly similar to lineweavers prefered jetting. different but close....

i've recently gone to the following;
158 MJ (down from 160)
200 MAJ (up from 180)
DMT needle on c4 (larger straight than DMS)
35PJ (down from 3 8 )
45 PAJ
.028" of APJ
1.5 turns PS
#75 starter jet (down from #80)
will be going back to 'E' series again soon. however the rekluse is knackering the bottom end a bit. need to get rid of a bit more of that slipping clutch feel to get valid results.
just a reminder that the bike has a '53' cam and an FX pipe with 501/550 headers. but a DVR needle is where i was at with the standard bike and everything else is pretty much the same.

i have a 04FE550. i have change the orig. exaust against the sil motor exaust. Now the jetting is wrong. i have already change the mainjet from 175 to 188. But the plug is white. The power in the low rpm is ok. in the middle it could be better. in the high rpm the engine runs not with enough gas. Because that the plug is with. Should i change the main jet againgst the 195 or 205 main jet?

i'm coming to the conclucion that YOU CAN'T GET A PLUG COLOUR WITH THE KOKUSAN IGNITION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
i have told the tale there of how i ran a new ignition on my F2 ducati in 1989 and only ever had a white plug.
go back to your original jet. indeed 175 was too high and a 168 or 170 should be fine. raise the needle one clip.
please let us know how it goes!

i also have dales kit husabutt. my tale about the white plug at the MGP is somewhere in the archives of UHE. it's well worth reading because it represented a season of heartbreak and lost money.
what i learnt the hard way i pass on in a one sentance post on UHE.
i'm tired of saying it. it seems the only thing people believe is either from dale or basically don't bother.
i've been here three years and i don't think i've passed on one bit of info that i can say has stuck! it's just IMPOSSIBLE!
how many times have i said "split the pipe and look down the middle".
answer this for me-but not here; in your head or PMing me will do. what MJ did dale give you?
what MJ are people trying to fit to their 04/05 550's?
now you tell me which one you believe now! it's dale isn't it!
but before you got the kit and i put up the post 'somethings wrong here' on that 550 thread, when i said that, what were you thinking? smelly stuff from mr lloyd again? i think so
they're getting white plugs with 180 MJs!!!!
what else can i say anymore. it's enough to make you weep!
ma lord the defence rests it's case :wink: :wink:
