Bike cuts out when i try to put bike into gear,was fine.

Do you have the kickstand up when you put it in gear? Many bikes have a lockout on the side stand to prevent you riding away with the stand down. Kills the engine instantly when placed in gear with the stand down.

Hi dont know if this helps but i had a problem with my freewind when i put the bike in gear it would run in tickover but when in tried to rev the bike it cut out, the problem was the cut off switch on the side stand you can test this by finding the wire, disconect at at a connection and use a piece of wire to compleat the circuit that solved the problem for me i just left it by passed.
hope it helps Neil

Hi. There ae numerous forums/site for your bike's FI codes. Since I don't know what code your FI is flashing, all I can say is put the FI code into your computer google or yahoo search area, and you will get an answer. Yiur FI should flash a few times first, and that is the first digit in the sequence. A second later, it should flash again, and that is th 2nd digit in the code. an EXAMPLE is 2 flashes, pause, 3 flashes...then repeats. That will be a code 23. Trust me, you will find the FI code online. Good luck!

Check for proper operation of side stand switch, clutch switch, neutral indicator lights up as it should on neutral gear position.

Did you try an impact driver? How about putting the bike in low gear? If not, just get a breaker bar on there an whack it with a brass hammer. I'm pretty sure it is a right hand thread. Hope this helps.

now you would have to make sure your clutch is not faulty as if the bike slightly jump while putting it in first gear and cuts off , you most probably have a clutch problem .
this is what you have to try first :
start the bike on while depressing the clutch while in gear and see what happens .
if the bike keeps on running , tension the clutch .
if the bike stall , your clutch could be faulty or your oil could be too ,thick and needs changing .
try this first and let me know how you go

Your kickstand switch is either broken or out of position. The bike kills the engine as a safety feature if it thinks the sidestand is down and the bike is put in gear while the engine is running.

hello and welcome
it seems that you may have a faulty side stand switch. the side stand needs to be in the up position before the bike can be started off in gear. but if not the side stand contains a saftety switch that shuts the bike off when put into gear. to verify this you can check for spark when the bike is being turned over in gear with the clutch held in.
there should be two wires associated with this switch. a green, and green with white. so when the stand is up these two wires are connected, and the switch can be tested as such. thank you.

Does the bike have a sidestand switch that cuts the power if the stand is left down? If it does, disconnect it and temporarily join the ends together and try starting....
