Hi all, I am new to the forum,
and here is my first post, problems of course..! :)
I have a
little problem with by bike. It has been standing for couple of years,
after which I bought it and now I am trying to bring it back to life.
When I first drove it, it worked quite ok, but seemed to be
somewhat lazy, so I opened carbs to see if there is some dirt etc. Both of
the carb membranes had several holes, which I fixed using Gorilla Glue
(which was probably bad idea, because it is way too hard after it dried).
Anyhow, I put those "fixed" carbs back and went on a testride. To my
surprise the bike is now functioning worse than before all that carb
cleaning and membrane fixing!
With low rpm (under some 3000-3500 rpm)
engine hesitates, coughs and sneezes, and on the traffic lights it might
even die, after which it is reluctant to start again.
After test drive
I took spark plugs out, and the result was: front cylinder plug was very
very white, and rear cylinder plug was very very black.
might be the problem? Maybe the membranes are broken again because of that
too hard glue? Maybe I should synchronize carbs (but can the lack of
synchronization have such dramatic effect)? Or can it be some sort of
ignition problem, although I havent touched the ignition timing at all? I
also didnt check the fuel level at the bowls.
I hope you could
give some advice, although I prob try to sync the carbs anyway, and if
that doesnt help, I take them out once again.
is there some upper limit how high speeds Cycom will show? Earlier I wasnt
able to get it over 85 mph, and now I tried few pulls but always 140 kmh
was the maximum. Although my clutch is slipping (problems, problems!) it
is hard to believe I always hit exactly the same top speed!
