Damaging the bike when starting without choke

 

I have this argue with my beloved one. Sometimes, when the
engine is not cold (note, it's not really hot any more), i
choose to start the engine without using the choke. It results
in a jerky sound from it. On an occasion or two it also died.

Now, the most beautiful in our houshold claims that it's
damaging to the hardware and should be avoided. The coolest
in our household claims that the only issue is to start again,
either with choke (if the engine died right away) or even
without it once again.

Who is right?

If the engine starts and warms, it's no problem. If you have to keep
using the starter ten or fifteen times every time you start the bike
because the choke needs to be on or doesn't work, then you will
eventually need a new starter.

On the other hand, if you leave the choke on too long, the engine will
run too rich, which has other bad effects on the bike.

So the best thing is to compromise: Use just enough choke so the bike
will start. Ride it gently, for that's a faster way to warm it up than
just letting it idle, then turn off the choke. (Five minutes of idling
just wastes fuel and puts unnecessary wear on the engine.)

#10 cam chain adjuster bolts. There are two of them. If you have a shop
manual to explain the procedure, you can loosen the lock nuts and then adjust
the cam chain tension and retighten the lock nuts.

The cam chain may need adjusting, or you may need to manually hold the
throttle open a little more so the engine idles faster.

It might help to adjust the carburetors, but turning the idle speed screws
without a vacuum gauge of some sort can cause the carburetors to become
unsynchronized.

Turning the idle speed up too far to quiet down the cam chain will defeat the
"choke" and make cold starting difficult.

Your engine doesn't really have a choke, it has a starting enrichener valve
that only works correctly when the throttle butterflies are fully closed.

 If it was my motorcycle, I would probably open the idle mixture screws about
1/4 of a turn.


Mechanical systems are often noisy and noisy cam chains can snap and cause
expensive repairs.


She is always right. If you don't want her to always be right, don't tell her
all your litle problems.

I never told you who's the beauty and who's the
coolness in our house... You're just excercizing
your prejudices! (And yes, you happen to be
right, but still...)     :)
