riding my AN650 2012, hadn't ridden in long time, installed new battery, started, ran normally for 5 minutes, then. the red F1 light came on and seemed to lose power, I could accelerate very slowly, but if I gave it any gas it would just rev and not speed up.

Any help appreciated.

If it appears to be stuck in first gear and hasn't been used for a while then check the centre stand switch as it may be sticking. check out le dudes info on getting the fault codes up

I'd check the battery connections again.

Do a quick look at the wiring around the seat and battery areas. Rodents like to chew.

thanks for your help, was unable to get back to the bike until now.

In summary, my AN 650. 2009, not 2012, F1 code came on after replacing the battery. Bike starts, but "never gets out of first gear, very little of power being transmitted to the wheel. Center with seems not to be stuck, and wiring looks ok. I did LeDude's trick of shorting the plug to get the F1 fault code. Initially there was no code displayed, but when I started the bike on the center stand, I got code of " -COO. "

Any advice of what this means, and what to do about it would be appreciated.

when you shut off the bike you lost yer code, you gotta get the fault indicator light again and check the code without turning off the bike , get it broke, stop, pop it up on center stand , jump the dealer mode switch, record the code, get back to the house and have a few refreshing beverages to prepare yerself for what the code means. probably the discomababulator is malfunctioning, and the bike has a problem too.

this time, I connected the 2 wires as directed, then started engine and initially code was C00, then changed to C58, which means CVT reduction ratio disagreement.

I hope somebody knows what this means, and I hope the situation is not too dire...

Bump. F1 light on, code is C58, "CVT reduction ratio disagreement". Anyone dealt with this before, any ideas where to start?

Thanks.

any maintenance done between the time you rode it and it was fine and now? I am thinkin there are a couple sensors in the cvt and if they don't jibe with other things you might get this code kkgood news is , one is easy to get to , bad news is the other you gotta use a borescope and tweezers, go in thru the tailpipe, around the left headlight and back over the top to the bottom inside of the cvt to see it.

C58 means the primary pulley and secondary pulley may be having a fight over their respective positions. Could either be sticking primary pulley sensor or debris causing the pulleys to stick in different locations. You could pull the PPS and see if the plunger operates smoothly with no crunching and make sure it is nice and clean. Need to take Tupperware off though to get to the top hex bolt to get it out. Stick a hoover over the hole as well see if it sucks and debris out.

No recent maintenance, rode it about once/ month over the winter, did not use tender, then the bike would not start due to dead battery, which would not take a charge and I replaced it. Immediately after that, the F1 light and engine racing and very little power getting to rear wheel

Just remember us old folks like to give advice. It may not necessarily be correct advice but it is free 😉
