Posted November 28, 2010 - 12:57 PM
right now the bike starts fine, if i put the choke on......the bike still runs.
my mid range is ok. my low and high end arent right. Help?
i removed the exhaust.....actually very clean. not much carbon build up at all on the jug end. im getting nice blow out from the other end. any ideas? i dont think its a dirty carb issue but how i have it set on the needles.

when you say "main" do you mean the thing with the 4 or 6 little holes in the end of it? its clean as a whistle. i made sure the little holes were clear, it got a bath in carb cleaner and blow out. I can see through every orfice in it. is that what you mean by the "main"? the exhaust is clean. pulled it off the jug.
check out the pictures...................
hows the plug look? it was installed yesterday..........rich or lean?
is this normal? every once in awhile the breather tube from the carb pukes some fuel then stops. seems when i put the bike on the stand or something?
and here is a picture of the bike.......not bad shape at all!

Puking fuel is not normal, it shows that the fuel level in the carb is too high for some reason, such as float level adjustment. It could also be due to the float pivot binding or a faulty fuel needle and seat which are not sealing properly. It seem s as though you have probably found your problem, you just need to find out what is causing it.
Strange, the plug looks good, but if the fuel level is too high the mixture will be rich and the plug will generally be black or dark in color.
The exhaust might look acceptable at the exhaust port, but still could be restricted somewhere down the line, like where the expansion chamber chokes down to go into the silencer.

If you search here in the peewee section you will find a relatively simple mod that will give your bike a two speed tranny. The gears are already in there, you just have to modify the bike to enable first gear.
There is an extra pilot jet in the carb to tame the bike for newbies; yours may have already been removed.

are those the little tiny things i removed? one on top of the other? the bottom one ws longer then the top......what one do you remove? you have to remove the top one to get the bottom one out.
Yup, the 2 small jets, stacked on top of one another. I believe you remove the first/long one.
