So I replaed the basket and clutch pack a couple weekends ago. bike started fine, but I couldn't ride it because of rain. Tried to go on a ride with my brother yesterday and of course the battery was dead. Bike sat on charger all night but I still can't get it to charge. It sounds like it barely wants to turn over. It's a lithium battery only a couple months old. Took a video and put on youtube of trying to start it. https://youtu.be/ZSRCNlN1MAo (https://youtu.be/ZSRCNlN1MAo)
Any idea what's going on? It's supposed to be nice this week and I would really like to get a ride in.
Those batteries are reported as very fragile when they go below a certain charge.
It might be dead....
What type and what size (amp hours and CCA)? Reason I ask is that I found a hard starting Marelli 1100 with a tiny little Li knockoff with insufficient amp hour capacity and CCA for the demands of the motor and the Marelli starting programme.
if the voltage goes below ~10.8v with no load the cells are toasted.
So I just put the voltage meter on it. With nothing on the battery ready 13.2 volts. When I tried to start it it bounced around from 7.4 to 10 volts during the starting process
actually its loaded*
i remember this video i made. turns out it was the battery.

I just installed a brand new battery and had the same result. What's my next step? Could it have something to do with the clutch replacement? It did start right after I got done though..
Are your trying to start in neutral with the clutch lever held in? Bleed your clutch and double check your lever adjustment. After that I would look into maybe some loose battery connections.
Before anything make sure the engine is free to turn mechanically. Remove the spark plugs, then, if you have one, turn the engine with a turning tool. If you don't have the tool, raise the rear wheel, put the bike in 6th gear and turn the wheel slowly and carefully. Remember, that wheel gives you a lot of leverage.
All right, removed spark plugs and put it in sixth. It took a fair amount of effort to turn the wheel, but I'm not sure what it is supposed to feel like
I've gone through and made sure all electrical connections are tight. It doesn't seem to be going through the whole start up process, I hit the starter and it only goes a couple of times, it seems like it should go on for a couple of seconds.
Also is it normal to hear air during starting? I would assume so since the cyliders are moving, but I've just never heard it before

I'm *ASSUMING* that the air you're hearing is coming from the cylinders because the spark plugs are removed. I may be wrong.
I reinstalled the sparkplugs..probably out of the airbox no?
I know I hear my cylinders sucking air, I have pod filters however. Don't think I ever heard it from the factory un-modded airbox.
The top has been cut off. so not completely stock. But it doesn't explain why it won't start..

should not be a lot of force to turn in sixth with the plugs removed (from both cylinders). it should be no harder than trying to roll a car tire up a moderate incline. once you get it going it should be also fairly easy. if you have a rusted chain then it may be harder.
did you put in your pressure plate with the notch lined up and all. the basics. if you didnt well. thats a problem.
from here, id start with the basics. check for spark. check for fuel, then check your ground.
Pressure plate is lined up-I think-It had a hole in one of the arms and I matched that with the split post
It took a lot of effort, definately more than rolling a tire up a hill
Chain is well lubed
Bike started and ran last week. No changes to it have been made since then.
Where would I find the ground?
Thanks for the input everyone btw.
trace the rear brake to the cylinder reservoir. its in that area. its a cable that goes from the battery to the engine case where the breather hose is.
when it last run, did it run well? or did it run like crap? when you swapped batteries, how do you know it was good?
It ran well, I was testing because I had just replaced the clutch pack. Got the battery brand new today and the guy tested it at the battery store

Did you happen to disconnect a ground wire from the ECU? I know I did that before on my S2R800 and mistakenly grounded it to the battery and I had similar symptoms.
it is slightly possible that you did not install the clutch basket correctly and you may have not tightened it enough and it backed out causing some sort of resistance. Take apart the clutch down to the basket and check those bolts that hold the basket down. thats all i got for you without actually being there. Worst case scenario. install the old clutch and see whats up. maybe you did something wrong during the installation.
Between watching your video and posting I forgot that it cranks but slowly, sorry about making you go through the work. First step is to confirm you have a good battery. That, in your case, means buy or borrow a known good battery, make sure it is fully charged and passes a load test. Easy alternative is jump it with your car, just make sure the car isn't running. One of the problems with lithium batteries is, at this point, there are no good way to field test them. Diagnosing a starting or charging system with a bad battery is like pissing up a rope. If it still cranks slowly you need to go further. You could randomly clean and tighten things hoping to solve the problem or work with your head. A meter and measuring voltage drop is the way to go. This means finding out how much voltage is lost at each connection and component.
This will save me a lot of typing. http://www.aa1car.com/library/voltage_drop_testing.htm (http://www.aa1car.com/library/voltage_drop_testing.htm) Yes, it is for a car, but same thing.
SOLVED [thumbsup] All right, because I'm too lazy and stupid to start checking voltages I started taking stuff apart. I actually had a theory but I thought it was ridiculous so I didn't check it out. It turns out there is enough drag on the new EVR basket from the gasket between the clutch cover and engine case that it wouldn't let it turn over. I took the cover and gasket off and remembered that I thought it rubbed a bit so I tried to start it-No issue starts right up. So now what do I do? Can I shave down that gasket or will will the world come to an end?
Thanks everyone for their input. I really appreciate the time and effort you have all taken to try and help me.
