TrIbbeY Posted May 9, 2012 Report Share Posted May 9, 2012 Ok guys im new to this forum but not new to the forum world.. i just got a 1999 banshee tonight that i traded my yfz450 for and the only problem im having is it wont stay running it wants to die out... when i let it idle the lights start to dim fast and when i give it gas the lights get real bright im thinking its my charging system/stator is weak or maybe my carbs arent set right/ may need cleaned? im used to 4 stroke quads and 2 stroke dirtbikes (which i hate dirtbikes lol) are there any common problems the 99s had that i should be aware of?

sangheraent Posted May 9, 2012 Report Share Posted May 9, 2012 A real problem I'v noticed with 99 banshees is that rear tires tend to wear very quickly. Most banshees are the same they only changed a couple of things throughout. your problem sounds like jetting your lights are suppose to do that.

banshee760 Posted May 9, 2012 Report Share Posted May 9, 2012 Banshees arent suppost to idle for long remember these are 2flat stroke motors that are air cooled. They dont have a battery or a fan like your yfz did there for what really is giving you power is the rotation speed of the crank amping up the stator. That s why the light get brighter as you rev up the gas the only problem with 99 or other banshee are. Destroying your tires and are anti being riding slow lol welcome to the forums Quote Link to comment Share on other sites More sharing options...

Destroying your tires and are anti being riding slow lol welcome to the forums Banshees are liquid cooled. If jetted properly, your bike should just sit there and be able to idle. I wouldnt reccomend letting it idle for extended periods of time, just like with any quad, but a couple minites is fine. Quote Link to comment Share on other sites More sharing options...

As said above the dimming of the lights is normal. What you should worry about is how it runs through the powerband. If it pulls smooth with no hesitations throughout, all you probably need to do is adjust your idle screws. However if thats not the case then you will have to look into your jetting. The best place to start is with a plug chop. There are articles on this site and on the internet with methods of how to do it. You want to start with a plug chop and get your main jet dialed in and then work down from there to your needle, pilot jet, and air screw. Either way i would definately do a plug chop to make sure your main is dialed in. If the previous owner didnt have it jetted properly you could be running lean and overheat then fry your motor.

Thanks guys it pulls through just fine with no stutter or weak pull so i guess for now im in the clear but ill just see if i can tune the A/F screws right to have a idle for a few seconds cause the only thing ill admit i hate is kick start lol does it help charge keeping the lights on like how it is with a 04-06 YFZ?

bansheesandrider Posted May 9, 2012 Report Share Posted May 9, 2012 does it help charge keeping the lights on like how it is with a 04-06 YFZ? Therer is nothing to charge, Banshees DO NOT have a battery. Quote Link to comment Share on other sites More sharing options...

sheerider11 Posted May 9, 2012 Report Share Posted May 9, 2012 You can put a battery if you want. You won't gain anything. Just now you can use LED lights that are bright as fuck. Quote Link to comment Share on other sites More sharing options...

The radiator needs airflow to cool. There's no fan to draw air to dissipate the heat. But I agree it's not gonna happen in 5 minutes .

zach45 Posted May 9, 2012 Report Share Posted May 9, 2012 Mine don't overheat... Just the other day I had it in my drive way for 30 minutes or more just idling... Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
TrIbbeY Posted May 9, 2012 Author Report Share Posted May 9, 2012 well only thing i can guess is that my carbs need adjusted by the a/f screws hopefully but no big deal Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted May 10, 2012 Report Share Posted May 10, 2012 Make sure carbs are synced. Quote Link to comment Share on other sites More sharing options...
