Well like they say " dont fix whats not broken" this ones biting me in the a**.
I have a 1997 yamaha banshee with vforce 3 reeds, boost bottle, K+n airfilter, and jetted carb.
Im suppose to be going riding monday but if i cant get my bike to run there go those plans. I decided to do a little maintence because i was bored. I cleaned the air filter and took off the carbs off the bike to clean the entrance of the carbs where the boot connects. I did not take any jets apart or adujst them all i did was spray down carbs to clean them. I put the bike back together took a few kicks to start would not stay running unless i stayed on the gas also only 1 cylinder would smoke also when on the gas. I shut off bike losen the tors caps and she starts right up and both cylinders are smoking which is good to me she revs nice and stays running no problem. im guessing the tors cap were too tight causing some type of problem but i am not worried about that because she runs now. I let her idle for 15 mins idles fine no problem then it starts to rev up a little by its self and dies out swapped the plugs starts right up idles fine revs nice. I go for a test ride it rides nice has low end power but its just not simply hitting powerband i dont know what the problem could be all i did was take carbs off spray them down cleaned airfilter and put bike back together. The bike ran like a champ before i took carbs off any help in the right direction would greatly be appreciated.
after test riding for 15 mins and making some passes i check the plugs and one plug is darker than the other.
