incontenant buffalo carbs

Post by two-stroke-brit »

hi guys ,i am suffering from a strange malady,
incontenant buffalo carbs :?
i have been using the bike to ride to work to try an hurry along the breakin of the new cylinders etc.
i leave at 5am and regulary but not always the center and/or righthand carb flood when i pull up to the first light and then on until i get to work (7 miles).
i turn it off and leave it until lunchtime when i use it again and it never floods until the next morning.
it is texas and 75 degrees at 5am ,95 by lunchtime.
i have had the carbs apart so often i can do it in my sleep.
i have also changed the float valves to no avail.
any clues :( :(
thanks mark.

Mark did you inspect the brass seats the float valves sit in??? If the seat is compromised a new valve wont fully cure the problem.
Two strokes, its just that simple.

Dont forget the little red gaskets need to be good too, if not, well more leaking will come your way.

float not

Post by two-stroke-brit »

hi i think i have finaly sorted it ,
(all the carbs have new valves and seats now)
still floods :o
then i remembered reading on here that someone had a damaged float that caused intermitant flooding so i changed out the float and presto fixo .
not flooding now . :lol:
i should wait for a week of use without incident to pronounce total success.
plenty of false dawns when i thought i had fixed it before.

Leaky floats can drive you crazy! I hope it's fixed.

If you stroke it more than twice; you're playing with it.

Thats on my personal list when i have the carbs apart .. to give the floats a shake to hear if there is gas inside them . If there is .. time to replace :D

I totally agree there Dave, thats why I'm wondering if they were leaking and had in gas how Mark could have missed it.

fingers crossed

Post by two-stroke-brit »

the floats looked ok to me and i didnt notice any signs of damage, but it was worth a try and it worked.
i also dont understand how the prob would be so intermitant but my fingers are still crossed.
i should know if it stays good for a while.
but where would the fun be in that. :lol:
is the gap a bi anual event ,sping and fall ?
thanks mark.
