brian102 Posted August 2, 2008 Report Share Posted August 2, 2008 (edited) the situation: banshee screams when its cold, it doesnt run as well whenits hot, if i go in 6th gear wot down a field, then go to turn around when i jump back on the gas it bogs then finally takes off and hits power band soon as it stops bogging, im guessing the jets are a touch to big? they are outa the factory, it only does it when its warm out, like i just rode now and its 73 degrees here in michigan and it ran awsome, it was 85today and ran like crap off start, i backed the two air screws out a full turn and it seemed to acually help a little, but very little thanks also was wondering its all stock what plugs do you guys run , do you run the b9es or 8? i know the 8 is hotter but how much hotter? and is the 8 gonna make it run any better ? like burn more of the fuel up thanks for reading! oh and 32:1 on the oil is right correct? yamalube i just bough some mobil sythetic aswell itsmells good cant wait to try that Edited August 2, 2008 by brian102 Quote Link to comment Share on other sites More sharing options...
mopar1rules Posted August 2, 2008 Report Share Posted August 2, 2008 run the b8es plugs and drop down your mains 1 size on those warmer days. leave pilots alone, leave needles and clip position alone, and you could probably leave the air screws alone, when going from a warm day to a cold day. 32:1 oil ratio is fine. if it were me, i wouldn't run the ratio that rich, just a waste of oil. plenty of lubrication @ 50:1 ratio, with good quality synthetic oil like mobil 1.

brian102 Posted August 2, 2008 Author Report Share Posted August 2, 2008 you think that the sythetic mobile 1 is good stuff? cause its 6 bucks a qt. but if you use that 50:1 is fine? i guess that would makeup for the price difference, the exhaust really smells rich like you cant breath that crap..

brian102 Posted August 8, 2008 Author Report Share Posted August 8, 2008 so this is probably a stupid question i just dont wanto mess anything up this wont lean it out to much to hurt my motor will it i will be able to tell if its to lean? just wont hold speed or what for right now its just field riding no dunes or anything? maybe it will make it run a little cooler, it always seems to get really hot just messing around Quote Link to comment Share on other sites More sharing options...
ASRBanshee Posted August 8, 2008 Report Share Posted August 8, 2008 Making the fuel/oil ratio higher will make the bike run richer. You have nothing to worry about so throw that worry out the door. Running at 32:1 will make the bike run more lean with the jetting rather than running 50:1 which will make the jetting a little more richer since their is more fuel to burn.

However too rich will foul plugs, and too lean will blow it up. It is always better to be a little rich. Edited August 8, 2008 by boneyardbanshee.

brian102 Posted August 8, 2008 Author Report Share Posted August 8, 2008 so should i take the plunge and change the jets or should i just leave it alittle rich to be safe, will i notice any other horsepower increasement other than that sluggish take off Quote Link to comment Share on other sites More sharing options...

However too rich will foul plugs, and too lean will blow it up. It is always better to be a little rich. yeah, 50:1 is leaner "OIL" wise vs 32:1...yes, but 50:1 will allow more "FUEL" to pass through the jets, so its richer "FUEL" wise. brian102, you could drop your mains 1 size on those warmer days, but i would still switch to 50:1 ratio.

boneyardbanshee. Posted August 8, 2008 Report Share Posted August 8, 2008 (edited) ditch the yamalube, run the good stuff at 50:1 to start. use your b8es or br8es plugs. bogging in the lower end is your pilot air srew and jet, and then the needle jet mid throttle, according to the Clymer manual not your mains. they are on the top end wich sounds to be were you are running good.

brian102 Posted August 9, 2008 Author Report Share Posted August 9, 2008 yeah im running fine on top end, just like i said 2nd and 3rd gear taking back off it just hesitates some or bogs, i changed to the b8es, it was better today but it was also only like 75 when i was riding not 85 -90 degrees with high humidity, i did switch to the mobil with 50:1 now i gotta find somewhere else to get that oil from cause those quarts igot were just on throw away at our work cause we arent going to carry them anymore, so my manager was like take em home hah.
