mysterious engine cut out


Recommended Posts

has anyone had their banshee just die for no apparent reason, then after sometime just start again like there was nothing wrong? i was on a trail ride yesterday and probably an hour and a half into it, cruising along a firetrail in 4th maybe half throttle and my bike kinda popped and cut out. i thought it had blown again as it was similar to the last time it shat itself. after borrowing a bike to get the car and maybe an hour had passed i kicked the bike over and it started first kick, ran excellent again. i was ready to throw it in the bin when it died... this has me fucked at what it could be, any help?

bike is an 03 with athena 392cc kit, vitos pistons, fmf ssts, power core 2s, k&n filter with foam outawear, airbox with no lid, 27.5 pilots, 280 mains, needles in the middle position

the plugs are fine, i had a mate (not to bright!) hold his finger in the cap and i kicked it but no spark. came back with my ute an hour later and it started first kick... i am thinking maybe the jetski style kill switch maybe a bit shit?? i did pull it out then plug it back in but it just seems a little strange to happen as im just cruising along

is it a spark issue or could it also be a fuel issue?  im wondering if you were running the bolwls dry on your carbs without realizing it.........check your electrical connections, check the wiring to make sure its not melted or pinched somewhere, check and clean your carbs to make sure the float isn't sticking, and check your fuel cap and your fuel cap vent tube for something blocking it.....remember if those get blocked....your tank is going to go under negative pressure....

it seemed to be a spark issue as when i kicked it while my mate had his finger in the cap he got nothing. It has the jetski style kill switch on it, could this have a shit connection or something? i wont be able to have a look for the next week and when i can have a look at it the bike will be going with me on a trip down south, i just dont want it shitting itself while on holidays. the bike was running at a good temp to, just seems strange that it would go from no spark to perfect spark again without doing anything except the kill switch

So you just installed this thing?? So no it's not strange. You probably fucked up some where. Go check again on this thing.

Also, what is a jet ski style kill switch

yeh sorry for not being clearer on that, its a tether switch, its just easier to explain sometimes as i have seen more jetskis with them... no its not a recent addition, its been on the bike for as long as iv owned it ( the last 9 months ) and it looks as if its been on the bike for a few years. Sorry if my questions seem stupid, im new to banshees and im learning as im going along. Cheers for the help so far
