Yes.
Quote from: fsrdhNow my stupid question is : as the float level is adjusted when the carbs are upside down technically the higher the distance between the float-bowl/gasket surface the lower the fuel level will be when the carb is oriented correctly in the motorcycle .
Anyways to make it simpler, do I have to increase the distance between
the float and gasket surface to make it leaner?
ok besides that bike pulls realy strong up till 100mph (probably could go
with a bigger main but that would mess me up in lowrange too.
According to the method that you are using, the answer to your question as modified above is, yes.
A bigger main does not usually affect lowrange, as the pilot jets, pilot screw and float heigth affect this range.
Yes you increase the distance between the carb body and float top to lower the fuel level and this will lean the mix across the board (except for idle, I think). Playing with float height isn't as exact or as responsive as jet or needle changes. Float height is kinda like your base line, if you change that, you've changed everything and have to start over. Which is why I avoid it if I can
If your idle and just off idle (where pilot jet and mix screw play) is fine and top end is good, have you gone all the way to the leanest clip position on the needle (the one on the end)? If you haven't try that first before an out of spec float height. If that cures your low to mid range, but your top end is too lean (it will be hard to tell) THEN go with a larger main jet to compensate.
Thanks !
The bike runs fine on idle steady 1200rpms or whatever I set it to.
The problem was initialy with 0-1/4 throttle opening ( a litte to rich ) I had no luck setting the floats right so I compensated with the needle's E-clip
going one step higher to lean it out . The bike runs great now (40/122.5)
It doesnt want to pull over 100mph on 5 or 6 gear. I didnt have the chance to check the sparkplugs on full openings but will do that soon .
From what I know the correct way to jet the bike is to start with mainjets .
I have the K&N pod filter on the way and I want to set the floats & needles correctly before I rejet to fit the fuel needs of the new airfilter
You should start with selecting the best main jet first. The main does affect all of the rpm range, but mostly at WOT.
