sorry for the stupid questions but i want to learn. i have a 95 banshee thats stock with 200 main jets and 25 idle jets and the air screws turned out 2 @half turns. went riding yesterday ran good all day then lugged it around the trails at the end of the day and it fouled the plugs. the temperature was about 55 degrees. should i run a higher octane gas or change my main jet to a 190? it smoked all day am i mixing my gas to rich? its 32 to 1 pump gas 92 octane. i want the fiance to ride the atv but if it will foul plugs just luggin around she cant.any suggestions would be helpful. oh yeah the plugs were ngk b8es brand new that morning.

 

If your putting around trails that maybe the problem. Shee's dont like to go slow if they do they tend to load up. If you know how to keep revvs up you wont have that problem maybe some faster trails?

 

just make sure you open it up once and a while. When you are in the trails and you feel it starting to foul and loose power then just give it a quick good clean snaps and she should clean up.

 

Could try synthetic oil...it burns cleaner. Try a hotter plug, if shes just gonna be doing low speed riding, Make sure the air filter is clean, if its restricted, itll run rich.

 

Sounds like your keeping it in a low rev. Open her up every 5 min's and you shouldent have any problems

 

what would the number be on a hotter plug? she is learning to work the clutch so she wont be able to open it up when it starts to foul the plug. ill try a synthetic oil see if that helps but maybe look for a 4 stroke for her.thanks for the suggestions it really helps.

 

thats not true
banshees will not foul a new set like that going slow or lugging.
im pretty sure its the jetting i ride and lugg mine all the tiime and have never fouled a plug. I lugg it alot too

wait till sum other people help you out with jetting.

 

On NGK plugs, going lower( the number portion of the spark plug number) is hotter. A b7es is hotter than a b8es.
spark plugs
ngk

 

i use GOLDEN SPECTRO in my gas and ive NEVER fouled a plug, ever, even when i lugged it in the yard for about 20 minutes when i was sick.
