[slamdxterra]

hey guys i am new on here cuz i have always had a shop close by to build and work on my banshees but since moving now its all on me!!! Its a kinda pieced together bike that when i bought it the guy said it was all brand new! HAHA...anyways its been running good but i havent ridden it in forever...i have had it 2 years and ridden it 4 weekends at the dunes. Its bored over w new pistons, v force 2 reeds, stock carbs, cool head w 19cc domes, fmf pipes, dual k&ns w out wears. I believe that is all for performance...anyways last time i rode it it would start and had to compression start...tow behind a vehicle and that took alil bit but i put new plugs in NGK BR7es, changed the oil and cleaned the carbs and still wont start! I tried starting fluid...still wont start!!! I need help ASAP i am tryin to go riding this weekend!!! It feels like good compression and the motor was fresh...well supposedly when i bought it...i run C12 gas w 927. The jets are 280...i dont know pilot jet size or float boat clicks or any of that other stuff! I NEED HELP!!! ANYONE???

First check to make sure your even getting spark.

I'd change over to B8ES, then check for spark and fuel. Have u played with timing any?

check for spark like everybody else said. have you done a plug chop? 280 mains may be a little lean depending on where you live (elevation).

X2, Banshees should run a B8ES or BR8ES or some other variation in the 8 heat range. You need to check for spark. If you don't have spark, you need to ohm out the stator and coil per the manual EXCEPT when checking the secondary resistance in the coil you need to hook the meter leads to both plug wires and not from plug wire to ground. Also, check your pickup coil air gap- it should be .017 inches, about the thickness of a business card. While your in there make sure the flywheel is tight, the key is in good shape and look things over for damage, although if the stator is damaged, it should show up when you ohm it.You will need a flyheel puller to get the flywheel off to inspect the key and you really should have a service manual also. If all this checks OK, then see if you can find a CDI box to swap out and see if it runs.
