New battery still trouble

I have bought a new battery for the bike (97 250) I get 3 or 4 cranks out of it and it acts like it is dead. I know it is not the battery because you pull it out take to another bike, fires right up.

Is this a continuation of a previous thread? I ask in case some information was given there about the problem.

Check the oil level!!!!

If gas is leaking down into the case, it will do that.

ps... if so, change the oil too

Also if fuel is leaking into one of the combustion chambers the engine can lock.

Could the starter motor be tired and need a rebuild?

Finally got back to the ninja. Still not starting.
So far :
Carb rebuilt by ducatiman. Nice job.
New carbs boots
Valves adjusted
New plugs. Just pulled again to check for vapor lock, clean and I have spark.
New battery fully charged.
Oil changed and at a good level.


Hit the starter. turns slow like a dead battery.

Nice job Bug. Now I can only suspect the starter motor or starter relay at this point.

Check the battery voltage before cranking. It should be 12.7V if it's fully charged. Then check it when you hit the button. It should be over 10V while cranking.

If that checks out, confirm all the connections and grounds are solid. Then trace the power on the way to the starter to confirm you are getting very close to the same voltage there. If you are, it would suggest the starter itself may be the problem.

Are you measuring on the battery terminals themselves, or the connectors on those terminals? The reason I ask is you said it's a new, fully charged battery, and if the wire connectors aren't making a good connections to the battery terminals, they might measure low when cranking, even if the battery is holding its voltage well.

It the battery is really new and charged, and it's dropping to 6v during cranking, either something is drawing massive, cable-burning current, or the new battery is bad.

Tried a second new battery with the same result. As triple jim might be right "it's dropping to 6v during cranking, either something is drawing massive, cable-burning current"

She runs...... sort off. There is idle problem now. Idles great at 11/1200 for a couple minutes then up to about 3k for a couple minutes, then back down. I have looked of a vacuum leak. with no success.

Did you solve low-voltage starting problem?
What was issue and how did you fix?

Choke on or off when you start?
Do you turn off choke when it turns up to 3k-RPMs?

Low volts cured. The harness had rubbed on a bolt a damaged a couple of wires. Cleaned that up also replaced the new solenoid again. And she fired up.
Choked is on to start it. about 2600 to 3000 rpm. it does not take long for that to climb to 6500. Shut the choke down it will shut down. start it back up down the choke down real slow she will run at an idle with no choke but the idle is erratic. My first thought was vacuum leak. but I could not find one.

What's your pilot screws set to?
Have you done gas-cap mod?
How long had bike sat?
Did you flush out all old gas from tank?

Does it do this on the road when you are riding, or in the garage when idling?

I'd look at the gas like JR suggested. If there is any question, drain the tank and floatbowls completely. Catch the gas from the floatbowls and look for water or debris.

Check the tank for rust.

Check the inline filter at the carb inlet for debris.

Check the air filter and be sure the snorkel is clear.

Are the idle mixture screws at 2.5 turns out?

Set the idle speed to 1300 when fully warm.

I have not taken the ike off it's table yet. So it is just sitting.
Floats look real nice. Ducatiman did a great job of straighten them out.
I have not checked the filter. Did not think of it, none of the other bikes have one.
Filter is new and snorkel is clean.
Screws are 2.5 out.
Tank was cleaned inside by a radiator shop. Now it has been on the shelf for a couple months. But I have a climate controlled storage cabinet for that. Because I live so close to the coast. New gas Tuesday.
No gas cap mod done. Not even sure what that is.

It is almost acting like some sort of vac system failing. Like the valve gets suck dry or presurized then magically find air somewhere.

I know when I find it, there will be something simple. I an feel it.

Fired her up this morning. Left time for a decent warm up. And decided to go for a short ride. So of we go to Half Moon bay (13 miles)figures some coffee a snack then home. Beautiful weather, bike riding nice, traffic going back is a parking lot because of are Fog Fest. So next stop, Santa Cruz (50 miles more. Then the back road home, up 17 to 9 to Skyline up to Half Moon bay a home. Total of 140 miles. She did good, still a little something in the idea (couple hundred rpm) but not like before. So thank all for your help and comments. We did it
