Honda 650 starting problems when very hot
|
Hi: I own a 1981 Honda CB650 custom, 30,000 kms on it. one of my
problems is after riding for a while, I cannot shut it off and have it
restart again unless I wait about 5 -10 minutes. It barely cranks over
at all. After about 5 - 10 minutes, no problem. I have been told that
it is the coil and I have also been told to advance the timing a bit.
|
Could be a weak Battery if the engine barely cranks over. No more cheap
batterys for me. Coil has nothing to do with the engine cranking over.
|
While I am at it, I just had all the upper gaskets changed and since
then (also when the bike is hot) I cannot sit at a red light and kick
it into neutral. It will always go into second.I was told by the
mechanics that they did not touch the bottom end of the motor. The only
thing I did was after I got it back, I changed the oil and did put too
much in but I siphoned most of the excess out. Could too much oil
cause this sort of a thing?
|
Too much oil - not unless there`s an awfull lot of it.
if it shows a reluctanct to crank, your problem is not in the ignition.
If it cranks easily when cold, suspect some sort of temperature
related friction. (probably serious).
Did the cranking problem start right after the gasket work???
Is your mechanic SURE that nothing got dropped into the lower
case??????
Check the oil pressure hot & cold????

I was thinking it could be a venting problem in your gas tank. Vapor
lock maybe.... Have you tried starting it with the gas cap off when its hot?

Yep, did the same thing to my FT-500 Ascot. Couldn't find neutral until
I drained the excess
|
Any info or comments would be appreciated. Thanks in advance

I have the same bike and the same problem. As for the starting problem,
it's one of two things. the starter is bad or needs cleaned, or the
charging system isnt working.
I found my problem was the voltage rectifior was bad and not keeping
the battery charged. As for the shifting into neutral, the clutch may
be worn or out of adjustment. If you dont have one get yourself a
clymer service manual(at any honda shop about $20) it is very detailed
and gives step by step insturctions on how to test all this. Good luck.
