This isnt because of the carbs this is due to the extra wire conected to the cdi and the neutral switch changing the amps or ohms that run threw it!

the talk about the carbs was due to the fact that our bikes dont have more powergain beyond 13k.
which (as i presume) is (in my case) because the carbs are lean

mine should be bone stock, i only raised the clip one place.
Ehh, the muffer's as good as empty, there's a rattling sound

i guess i burned most of it out, but i like the sound now. Kinda "raw"

my B4 is pretty standard exept it has different air filters (four of these but not K&N)
last week i checked my spark plugs and they were way to white.
so i opened the carbs and removed the 110 jets and replaced them with 130 jets (because i still had those)

now it is to rich (i will buy some 120 jets after x-mas) but it has a bit more from 6k to 14k revs, atleast thats how it feels...
in 6th the max rev hasnt gone up

also i noticed my needles dont have different settings, so i cant raise them. but i saw there were alreaddy small plastic thingies beneath them to raise them about 2-3mm

i also couldnt find a carb code on it (10D1 or 102) which is also strange

Bartjan · « **Reply #24 on:** December 23, 2006, 03:01:58 PM »

i wont

1st of all i dont have the money for it.
2nd if i did, i would prefer to spend it on other things.
3rd i like trying it myself (i study automotive engineering at school (hbo bachelor, final year), so i should know what im doing)

4rd it doesnt run bad, just not as good as some others

Its the flow that the new needle has is why you want one

Bartjan · « **Reply #26 on:** December 23, 2006, 03:11:26 PM »

gsxr400 racer · « **Reply #27 on:** December 24, 2006, 09:53:26 AM »

Hi gues. I made a decition to rebuild my CDI(just changing capacitors really) and when was taking off the CDI noteced that i have only 2 wires on a small plug and my bike suposed to be 1994. A while ago i came to conclucion that its a 1992 model ( N ), but still not 100% sure.
Just thought i share it.
Getting my carbs rebuild ( Got the kit from Jay) and servicing it too.
Cheers
