i have a 06 ltr that i was riding all day with several beer breaks lol and the all of a sudden when i tried to crank it it ran for about 3 seconds and stalled the it would not start at all pulled the tank off and pulled the plug it had zero fire swapped the coil for another one i had laying around and now it has a very weak fire and still will not start when i say weak u can see a spark but its very weak looking you can hold the plug in your hand and turn it over with a very faint tingle could this coil be bad also or what could it be has anyone ever has anything like his happen any help would be greatly appreciated

Sure it's possible that both coils could be bad. Did you check for any trouble codes? Possible CKP sensor going south?
i dont know how to check the codes do i need a scanner for it or will it scan its self this is my first ltr
Ground the white/red wire in the CRBM connector and count the flashes on the FI light. Then go to the service manual for the diagnostic chart of that code.
i can not find the red white wire to short out what is the CRBM connector is it in a plug do i need to unplug it to short it out lol srry i feel like a newbie now im sure its something simple and im just getting frustrated today i put a meter on the connector for the coil and it only has 2 volts on it with the motor turning over and i also unpluged the ckp sensor and the spark stayed the same weather the sensor was pluged in or not

i hope this info will help thankyou i will look for the wire again in the morning
The CRBM connector is under the right front fender area. Most likely you have a cherry bomb plugged into it.
I think the service manual shows the location of it. It's a 6 wire connector.
ok i found it lol i was looking right at it its plugged into a fi2000 controller i grounded out the wire and it didnt show any codes the lights just came on as normal and went back off
