I have a stock yamaha banshee, i take it out today for little ride, choked and started good, i start riding everything is good, power is perfect, but when i hit the throttle it smokes white, the more i hit the more it smokes... i was riding about 5 minutes doing some wheelies ... etc then i lost power!! here's what i did: 1. removed old plugs and putted new NGK's 2. removed carbs and cleaned them 3. checked the compression very good BUT !! its still smokes white so much so much !! never seen this before even when it idling, only the right side is smoking... the fuel i am using is little old, i mixed it month ago... thanks Quote Link to comment Share on other sites More sharing options...
black sunshine Posted April 19, 2009 Report Share Posted April 19, 2009 How's your coolant level? Might be burning it... Quote Link to comment Share on other sites More sharing options...

If it is right side only, your crank seal may be leaking. The smell is very noticeable if it is burning gear oil... Quote Link to comment Share on other sites More sharing options...
CoreyReid Posted April 19, 2009 Report Share Posted April 19, 2009 i would guess X2 on burning coolant. Quote Link to comment Share on other sites More sharing options...

LS1Inferno Posted April 20, 2009 Report Share Posted April 20, 2009 No, coolant level is ok... Is it both sides or just one side? and what ratio are you mixing the oil at? Quote Link to comment Share on other sites More sharing options...
GhostRider Posted April 20, 2009 Author Report Share Posted April 20, 2009 (edited) Is it both sides or just one side? and what ratio are you mixing the oil at? no, not both sides, only right side, half yamalube oil liter with 25L fuel..

KlotzBanshee Posted April 20, 2009 Report Share Posted April 20, 2009 If it is right side only, your crank seal may be leaking. The smell is very noticeable if it is burning gear oil... X2 time for new crank seals. Quote Link to comment Share on other sites More sharing options...
GhostRider Posted April 20, 2009 Author Report Share Posted April 20, 2009 X2 time for new crank seals. So how could i change the seals ? tear the bike down and open the crank case? or from the clutch cover? do you have crank seals picture? and what do i need to change it...

LS1Inferno Posted April 20, 2009 Report Share Posted April 20, 2009 You need a crank seal kit, you can get them from many places if i have to do seals i just replace both but the one that is bad is the one in the red box you should replace that one AND the one on the stator side just to be safe plus a few more bucks is good insurance. Burning oil is one thing, burning pistons is another. And unless you want to inspect other things, which if its the first time this motor has been apart I would, you can cheat and leave the top end on and split the cases upside down and just lift the crank enough to get the seals on and off and BTW its easier to get that nut off before you slit the cases.

KlotzBanshee Posted April 20, 2009 Report Share Posted April 20, 2009 Do a search on Leak down test :thumbsup: Buy a Clymer's Banshee service manual. Quote Link to comment Share on other sites More sharing options...

LS1Inferno Posted April 25, 2009 Report Share Posted April 25, 2009 Yes but like i said you can get a kit with aftermarket ones cheaper then each at the dealer. Quote Link to comment Share on other sites More sharing options...
liveordie72089 Posted April 25, 2009 Report Share Posted April 25, 2009 When you took out the spark plug what color was the plug? It's supposed to be brown. As for the coolant i would definitely check that you don't want that getting into your engine. Just do a leak test and it should tell you if its that.
