Brian :

Good day and welcome to Just Answer. My name is XXXXX XXXXX I'd be happy to help you with your problem today. Do you have a multi meter?...

Customer:

Somewhere

Brian :

was the fuel left in there all winter?

Customer:

I could go find it I think

Brian :

we will need it

Customer:

yes

Customer:

I spaced draining it

Customer:

Had planned to ride

Brian :

ok, thanks, XXXXX XXXXX least need a carb service. Your little pilot jets can't take that. And my guess is a new battery, but that is why we need the meter, to load test it & make sure..

Customer:

Sorry for the delay; tried to find the meter. I have a battery charger device hooked up that I think will measure the Voltage though it measures what is coming from the charger too

Brian :

we'll need to check it without a charger connected.

Customer:

I tried watching the voltage while starting the bike and it dipped back and forthe

Customer:

Okay I will see if I can find the meter brb

Brian :

that is what we need the meter to check more accurately. If the voltage ever dropped below 10 with the start button depressed the battery is junk.

Customer:

The battery is dead by itself. The bike will not turn over without the battery charger hooked up.

Brian :

then it is junk.

Brian :

you need a battery & a carb service. I'd also get a new set of plugs.

Customer:

I had the battery checked out last year and it seemed to hold a charge when the bike was clutch started. The bike would even turn over after riding for a while; seemed like it was charging

Brian :

it is junk now.

Customer:

Why wont the bike start with the charger hooked up? it is turning over.

Brian :

because the battery is junk & likely has one or more dead cells or an internal short, or the charger has welded several of the plates together.

Brian :

the plugs are likely fouled & you need a carb service.

Brian :

but I've said all this already

Brian :

I'm not sure what I'm not conveying properly.

Customer:

Dude chill; just asking since that did not make sense to me.

Customer:

I will try another battery

Customer:

etc.

Brian :

I am "chill" whatever that is. I just want to make sure that you are understanding what I'm saying is all.

Brian :

you need a carb service. you can not leave fuel in them for more than a month without issues.

Customer:

Can I try starting with the battery out of the bike just using charger?

Brian :

Your battery fails a load test when the charger says it is charged & it will not then turn over the starter

Customer:

I know you are right about the carb cleaning

Brian :

You can try it but you will fry your cdi box and then need one of those.

Brian :

The carbs are reason for the no start. The battery is just junk.

Customer:

okay; good to know

Brian :

2 separate issues.

Customer:

Can I do the carbs myself or should I take the bike in?

Brian :

I, unfortunately can not asses your abilities, you will need to do that. If you know & understand late model motorcycle carbs, go ahead, if you've never done any carb work I'd fine someone who knows them well, most dealers don't.

Customer:

Okay thanks Brian good night

Brian :

if you need any more info, I'm here frequently, just reply back. If you tear into the carbs & need help, let me know.... thanks for stopping by.

Customer:

No problem
