i have a 99 shee with pipes boost bottle and a tors removal kit. all of a sudden when i was riding it it began to sputter at full throttel. so i changed the spark plugs and gas. then i took the cards out and cleaned them completey and still does the same thing. now the quad idels and strarts good but under any load it it sputters and spits and wont rev up. if anyone has any ideas that would be great.
thanks
